1 Introduction 

ShoreZone is an imaging and habitat classification system for the coastal nearshore margin including the 

shallow subtidal, intertidal shoreline and supratidal fringe. One objective of ShoreZone is to produce a 

georeferenced, searchable inventory of the physical and biological attributes of coastal habitats. 

ShoreZone imagery and habitat attributes can provide a useful baseline from which to study change over 

time, while the attributes mapped (such as shoreline sediments, predicted oil residence and biotic 

communities) provide an important resource for scientists and managers. The ShoreZone mapping system 

provides a decision support tool with many potential uses, including community planning, facilities 

citing, conservation planning, research and fisheries management, emergency planning and response, 

search and rescue, education and habitat modeling.

The ShoreZone system was developed in the 1980s and 1990s to map coastal habitats in British Columbia 

and Washington State (Howes 2001; Berry et al. 2004). In 2001, ShoreZone was implemented in Alaska, 

beginning with Cook Inlet, Outer Kenai, Katmai, and portions of the Kodiak Archipelago (Harper and 

Morris 2004). ShoreZone has since expanded to a spatially continuous database of over 75,000 km of 

coastal Alaska and 45,000 km of British Columbia, Washington and Oregon (Figure 1). The NOAA 

Fisheries Alaska Regional Office manages the ShoreZone online database for Alaska, Washington State 

and Oregon. This database allows users to see high resolution digital coastal imagery, download photos, 

access or visualize mapped physical and biological data, and even download the entire ShoreZone 

geodatabase.

The Alaska Peninsula was a gap in the ShoreZone imaging and mapping of the State of Alaska due to the 

remoteness of the area and challenges of mounting a survey there. The purpose of the work conducted 

under this contract was to fill that gap by imaging, mapping and conducting ground surveys along the 

Alaska Peninsula. Relative to prevailing currents, the Alaska Peninsula is downstream of the Cook Inlet 

Planning Area and adjacent to the Kodiak and Shumagin Planning areas. This information will provide 

BOEM with comprehensive coastal habitat data to help analysts and decision-makers identify high 

priority fish and wildlife habitats in National Environmental Policy Act (NEPA) and Endangered Species 

Act (ESA) analyses and documentation for lease sales, Exploration Plans (EP), Development and 

Production Plans (DPP), and other efforts to analyze risk from spills originating in these planning areas. 

Figure 2 shows the 2,216 km extent of the Alaska Peninsula shoreline from Mitrofania Island to Bear Bay 

in Shelikof Strait) that was covered under this study.

The ShoreZone imaging survey was conducted in May 2016 and acquired aerial video and digital still 

images of the coast during minus tides (zero-meter tide levels and lower) according to the ShoreZone 

protocol (Cook et al. 2017). The ground station surveys were conducted over two low tide windows in 

May 2016 as well. The imagery and associated audio commentary were then used to map the physical and 

biological attributes of the shoreline according the most recent ShoreZone coastal habitat mapping 

protocol (Cook et al. 2017). A summary of the imaging, habitat mapping and ground survey results are

presented in this report. A catalog of benthic marine algae collected during the ground survey was also 

prepared as a NOAA Technical Memorandum (Lindeberg and Lindstrom 2018). That catalog was not a 

deliverable of the BOEM contract but acts as a complimentary report.

2 Imaging Flight Report 

This flight report summarizes the field activities of the ShoreZone aerial video imaging surveys 

conducted by Coastal and Ocean Resources in Southwest Alaska during the 2016 field season. 

The Alaska Peninsula survey was conducted by Team Chignik out of Chignik, Alaska (see Table 1 for 

personnel) from May 5-11, 2016 and collected imagery for 2,072 km of the coast, according to the 

Coast63 digital shoreline. Figure 1 shows extent of imaging and habitat mapping. A Bell 206 Jet Ranger 

was charted from Egli Air Haul based in King Salmon, Alaska and imagery was collected looking at the 

shoreline from the left side of the aircraft through large photography shooting windows. 25 HD videos 

were collected during the survey and recorded to MP4 format while a total of 14,709 photos were taken 

by the team.

The Chirikof and Semidi Islands survey was conducted by Team Chignik on May 8, 2016 while they were 

based in Chignik, Alaska. This survey was undertaken for the National Oceanic and Atmospheric 

Administration, National Marine Fisheries Service, Alaska Region (NOAA, NMFS). That imagery 

captured 183 km of shoreline. That imagery was also contracted for habitat mapping by NOAA. Egli Air 

Haul and their Bell 206 Jet Ranger were used to collect the imagery looking at the shoreline from the left 

side of the aircraft through large photography shooting windows. 2 HD videos were collected during the 

survey and recorded to MP4 format while a total of 1,595 photos were taken by the team

A summary table and map for each video, illustrating its location, length, and key geographic points is 

presented in Appendix A. Maps for each video are annotated with representative geographic names, photo 

numbers and video times in Coordinated Universal Time (UTC) which is 8 hours ahead of Alaska 

Daylight Time (AKDT).

All videos and photos were supplied to NOAA on a hard drive, organized by video number and named 

consistently with the ShoreZone image library data schema. GIS data and imagery are linked by a date 

time code (yyyymmddhhmmss), and the GIS data that accompany this report illustrate the flight track 

positions at 1-second intervals. That imagery has been posted online at the NOAA ShoreZone web site:

3 Physical Attribute Data Summary

This section presents summary statistics and distributions of some of the physical attributes classified in 

the Alaska Peninsula study area using the ShoreZone habitat mapping protocol (Cook et al. 2017). The 

length of shoreline imaged and mapped was 2,216 kilometers and was broken into 7,583 along-shore 

segments (units), averaging 292 m in length. The digital shoreline used for the ShoreZone habitat 

mapping was compiled from multiple sources to create the best available representation of the current 

shoreline. The primary source for this project was the AK_Shoreline_NHD_NOAA_Jan2015.

3.1 Coastal Class

The Coastal Class is used to define along-shore coastal units based on the dominant process, geomorphic 

features and other attributes such as substrate size, across-shore width, and slope (Cook et al. 2017, after 

Howes et al. 1994). The principal characteristics of each along-shore unit are used to assign one of 39 

overall unit classifications. Sediment shorelines (48.9%) dominated the Alaska Peninsula area. Rock and 

Sediment shorelines followed with 28.2% and Rock shorelines were found on 16.5% of the coast (see 

Figures 3 and 4 for summary statistics and distribution). The description for each Coastal Class category 

in the survey area is presented in Table 2. Photographic examples of the major Coastal Classes mapped 

for the Alaska Peninsula are found in Appendix B, Table B-1.

3.2 Environmental Sensitivity Index (ESI) 

The NOAA Environmental Sensitivity Index (ESI) is a shoreline classification system developed to 

characterize coastal regions based on sensitivity to potential oil spills (Petersen et al. 2002). The ESI 

system uses wave exposure and principal substrate type to assign a rank of 1 to 10 (with 10 being the 

most sensitive to oil) to alongshore units. Up to three ESI numbers can be assigned to each ShoreZone 

unit (high, mid and low intertidal) if applicable. The highest ESI number for each unit, which is the most 

sensitive, is used in this analysis. 

The Alaska Peninsula is balanced with a slight weight to the Low and Very Low categories (45.75% of 

shoreline length). These sections of the shoreline have a potentially low sensitivity to oil. At the other end 

of the spectrum, only 24.1% of the shoreline was mapped with a potentially high sensitivity to oil 

(Figures 5 and 6). The summary of Shore Type by ESI class is presented in Table 3.

3.3 Oil Residence Index (ESI) 

The Oil Residence Index (ORI) is a rating between 1 and 5 with a value of 1 indicating a relatively short 

oil residence (days to weeks) while a value of 5 reflects potentially very long oil residence times (years). 

An ORI value is applied to each alongshore unit and to each across-shore component based on sediment 

texture and wave exposure (Cook et al. 2017). The ShoreZone ORI is an algorithm developed by Dr. John 

Harper based on his many years of experience with cleaning up oiled shorelines and observing behavior 

of oil on shorelines, starting with the Exxon Valdez spill in Prince William Sound in Alaska. Lower wave 

exposures and unconsolidated sand and gravel sediments lead to high ORI values for 54.4% of the shore 

segments of the Alaska Peninsula, indicating oil residence times are on the order of months to years (see 

Figures 7 and 8 for summary statistics and distribution).

3.4 ShoreZone Coastal Vulnerability

3.4.1 Flood Zone Width

The Coastal Vulnerability Module (CVM) includes a classification of flooding sensitivity based on the 

across shore profile and photographic evidence of historical flooding such as an unambiguous marine 

debris line (Cook et al. 2017). The Flooding Class is an estimate of vulnerability to inundation of the 

terrestrial area beyond the supratidal. The distance to the debris line is measured and used to classify the 

flooding potential. Flat shorelines with very low gradients that show evidence of historical flooding have 

a higher risk of being inundated by storm surges. Potential for damage due to flooding is generally low in 

the study area, with 69.9% of the shoreline at a low risk of flooding <5m from Mean High Water (MHW)

(see Figures 9 and 10 for summary statistics and distribution). The flooding class is a parameter of the 

Coastal Vulnerability Index (see section below).

3.4.2 Coastal Vulnerability Index

The Coastal Vulnerability Module of ShoreZone includes several attributes that provide qualitative 

estimates of the vulnerability of a unit to impact from sea level rise, whether that is due to anthropogenic 

causes or natural phenomena such as storm surge (Cook et al. 2017). The ShoreZone Coastal 

Vulnerability Index (CVI) combines these attributes with several others from ShoreZone habitat mapping 

and combines them into one rank that assesses the overall vulnerability of a given unit to sea level rise. 

The methods of Thieler and Hammer-Klose (2000) were adapted to develop the CVI using these

attributes: Coastal Class, Max Tide Range, Shoreline Erosion Index, Flood Zone Width, and Wave Height 

(Cook et al. 2017). 

The Alaska Peninsula survey area was characterized by stable shorelines and low flood zone widths, so it 

is unsurprising the majority of the survey area (97%) was in the lower CVI ranks (Low and Moderate). 

See Figures 11 and 12 for statistics and distribution of the CVI, respectively.

3.5 Anthropogenic Shore Modifications

The Shoreline Modification attribute provides a thorough catalog of the specific types of anthropogenic 

modification in each unit (Cook et al. 2017). This can include multiple modifications within a given unit. 

For example, if both riprap and a pile-supported wharf occur, both are catalogued in the appropriate zone 

of that unit with an estimate of the alongshore length of the unit that modification covers. A total of 4.36 

km of the shoreline (taking the estimated length of that modification within the unit into account) exhibits 

shore modifications in the Alaska Peninsula study area (Figure 13). Riprap was the most commonly 

recorded observation (55.3%) with Landfill for 20.7% of the observations. Figure 14 shows the 

distribution of primary shore modifications, though it should be noted that any given modification is not

necessarily along the entire length of the indicated shore unit. The Geodatabase delivered with this report 

displays each shore modification with a specific length category (meters) for the shoreline pertaining to 

each unit and the specific zone in which the modification occurs (supratidal or intertidal).

4 Biological Attribute Data Summary

4.1 Biobands

Biobands represent assemblages of coastal biota found on the shoreline at typical wave exposures, 

substrate conditions and across-shore elevations. Biobands are spatially distinct, with alongshore and 

across-shore patterns of color and texture that are visible in aerial imagery (see Appendix B, Table B-2

for examples from the Alaska Peninsula survey area). Full descriptions of all biobands, including 

indicator and associated species can be found in the ShoreZone protocol (Cook et al. 2017). The metrics 

for measuring the biobands are detailed in the protocol document. The specific elevation (or Zone) of the 

bioband on the shoreline determines the metrics applied. Biobands found in the supratidal (A Zone) and 

subtidal (C Zone) are described by percent of alongshore length of unit and a width category. The 

intertidal (B Zone) biobands are described by percent of alongshore length of the unit and percent cover 

of the zone. 

The 29 individual biobands mapped in the Alaska Peninsula survey area are summarized in Tables 4 and 

5. Please note that number of units is used to describe the distribution of biobands in the tables rather than 

length because biobands are usually not continuous along the entire length of a unit. The survey area was 

remote and diverse in terms of geomorphology of the shoreline, with a range of shore types and exposures 

represented. Filamentous and Foliose Red Algae was the most commonly observed intertidal bioband 

(68.3% of units) with Barnacle only slightly less common (66.0%). Kelps were common in the survey 

area with three biobands of Bladed Kelps recorded (Soft Brown Bladed Kelp, Dark Brown Bladed Kelp 

and Bladed Brown Kelps). Together, they occurred in 71.2% of the units. Surfgrass was only observed in 

9.3% of units, mostly on large Semi-Exposed platforms (see Figure 15 for map of distribution).

Black Lichen was the most commonly occurring Splash Zone bioband (66.1% of units) while Dune Grass 

was the most common supratidal bioband (27.9%) (see Figure 16 for map of distribution). Salt Marsh was 

only observed in 6.7% of units, although it should be noted that both Salt Marsh and Dune Grass might

have been underestimated due to the timing of the imaging survey, which was conducted in early May. 

The Dune Grass was still brown at that time and the plants that make up the Salt Marsh bioband were just 

beginning to grow. The imaging survey needed to be early in the year to avoid disturbing Stellar’s Sea 

Lions, which are much more common on the Alaska Peninsula in the summer months.

Canopy Kelps were common in the survey area. There were two specific canopy kelps identified, Bull 

Kelp and Dragon Kelp. Where the imagery did not allow for specific identification of the kelp species, 

the general Brown Canopy-Forming Kelp bioband was used. Together, these biobands occurred in 50.8 

percent of the units, with Bull Kelp making up almost 90% (see Figure 17 for map of distribution). 

Eelgrass was present in 587 units (7.7%) so was not common (see Figure 18 for distribution) although in 

some protected bays and lagoons, such as Chignik Lagoon, it formed extensive beds.

4.2 Biological Wave Exposure

Biological wave exposure categories range from Very Protected to Very Exposed and are defined in 

ShoreZone based on a typical set of biobands. When present the observation and relative abundance of 

biota in each alongshore unit is used to determine the classification for the biological wave exposure. The 

assemblages of biota observed are then used as a proxy for the wave exposure at that site. For definitions 

of the Biological Wave Exposures and the exposure ranges of the biobands, see the most recent 

ShoreZone protocol (Cook et al. 2017).

The distribution of the wave exposure categories mapped in the Alaska Peninsula survey area are 

summarized in Figure 19, and a distribution map of the categories is shown in Figure 20. This was a 

diverse survey area in terms of exposure, with 44.3% of the shoreline length in the lower exposure 

categories (Very Protected, Protected and Semi-Protected), and the rest was in the higher exposure 

categories, with Semi-Exposed making up 46.1% of the length of the shoreline in the survey area.

4.3 Habitat Class

The Habitat Class attribute is based on wave exposure and geomorphic characteristics observed on an 

alongshore unit. The habitat class is intended to provide a single attribute to characterize the biophysical 

features of each unit. The habitat class is assigned by the biological mapper and weighted according to the 

dominant structuring process. Wave exposure is the most common structuring process, while less 

commonly observed habitats are those structured by current, estuarine/fluvial processes, and 

anthropogenic structures. For habitat classes structured by wave exposure, substrate mobility determines 

the presence of epibenthic biota. Where the substrate is highly mobile, biota is sparse or absent, and 

where the substrate is stable, biota can be abundant. For further definitions and explanations of Habitat 

Class codes please see the most recent ShoreZone protocol (Cook et al. 2017).

The distribution of habitat class categories mapped for the Alaska Peninsula survey area are summarized 

in Figures 21 and 22. Partially Mobile and Immobile substrate classes are the dominant shoreline types 

(71.6%). The Riparian, or Estuary, Habitat Class was rare (6.6% of the shoreline length) and is 

characterized by a significant source of fresh water flowing into the unit, the presence of a delta fan and 

the presence of marsh habitat (the Salt Marsh bioband).

5 Ground Station Survey Report

5.1 Introduction and Methods

The primary objective of a ShoreZone ground station survey is to obtain detailed geomorphologic and 

biological site information that compliments and improves the image classification and habitat mapping 

process and provides descriptions of the species associated with the biobands mapped in various habitats 

types and exposures. The collection of ground data can provide valuable information on regional 

differences in species diversity, species habitat requirements, and geographic ranges in Alaska and the 

Pacific Northwest. Hundreds of shore stations have been completed as part of the Alaska ShoreZone 

program. In the Gulf of Alaska, shore station data have been collected since 2002, including southeast 

Alaska, Prince William Sound, the outer Kenai Peninsula, the Kodiak archipelago, Cook Inlet, and the 

Katmai National Park coast. These data are spatially linked to the Alaska ShoreZone Database and are 

available through the NOAA online portal. 

The specific objectives of the ground survey on the Alaska Peninsula were to:

1. Obtain specific site information and enhance knowledge and understanding of ShoreZone habitat 

mapping classifications.

2. Conduct detailed site specific observations of substrate, morphology and biota to better 

understand coastal processes and ecology and to complement interpretation of biobands from 

aerial imagery.

3. Document differences in species and assemblages in biobands for different coastal habitats and 

exposures.

4. Collect photographic evidence of sites, including alongshore and cross-shore details, biobands, 

and select species.

5. Make the information publically available by adding it to existing state-wide Shore Station 

database served online at http://alaskafisheries.noaa.gov/shorezone.

The Alaska Peninsula ground station surveys were conducted during two low-tide periods from May 4 -

12 and May 20 – 27, 2016. Sites were selected from the BOEM Alaska Peninsula study area as well as

two sites on Chowiet Island in the Semidi Islands, which was part of the survey area paid for by NOAA. 

Two sites were also sampled opportunistically in Katmai National Park during vessel transit from the 

Alaska Peninsula study area back to Homer, Alaska (Figure 23). The survey team was supported by the 

Research Vessel (R/V) Natural Habitat Ursus for berthing accommodations. A skiff was available to 

access shore stations. Sampling was conducted within a three-hour window on either side of low tide to 

ensure sampling of the largest portion of the intertidal and shallow subtidal zones. The specific sites were 

selected to represent the diversity of wave exposures and Coastal Classes occurring along these shorelines 

(e.g. exposed rocky platforms, exposed boulder beaches, semi-exposed and semi-protected cobble 

beaches, salt marshes, eelgrass beds). An effort was made to sample habitats with multiple biobands and 

mixed species assemblages of individual species that may not be discernable from aerial imagery. 

The shore station survey was conducted prior to ShoreZone habitat mapping, therefore detailed habitat 

data were not available for randomly selected sites representative of all habitats. As a result, sites were

not selected based on statistical distribution of the range of habitats within the study area. 
31

Figure 23. Study area map showing location of ground stations. 

Adjacent sites may show as one symbol on the map. 

The shore station survey teams were composed of 3 to 4 specialists in ShoreZone survey and mapping 

techniques, Alaska seaweed and invertebrate taxonomists, and coastal ecologists with decades of 

experience working in Alaska’s intertidal zone. A brief description and schematic of the geographic, 

geomorphic, and biological characteristics of the ground station were recorded for each site. This 

information included habitat type, exposure, major features or uniqueness of the site (e.g. adjacent 

freshwater influx), and the relative placement of substrates, geomorphic features, and dominant biota 

within the site and tidal zone. Representative site photographs were taken from the upper beach towards 

the waterline and from the lower beach towards the upland habitat to show the across-shore habitat and 

relative locations of biobands. Site photographs included alongshore and cross-shore views to show 

relative positions and patchiness of substrate and biota and to place the shore station in the context of 

nearby habitats. Additional site photos focused on individual biobands, species assemblages, or individual 

species. 

A physical transect was placed within each site from the top of the beach to the bottom. It was placed to 

best reflect the overall shoreline habitat observed at that site. The GPS position was recorded at the top of 

the transect where the high water line was estimated to be. Profile breaks were established based on 

changes in biota (e.g. bioband divisions) and/or major substrate or slope changes (e.g. shift from a vertical 

rock wall to a rock platform or shift from a cobble beach face to a boulder field). Measurements of slope 

distance and vertical elevation were collected at the profile breaks to place features horizontally and 
32

vertically within the profile. Vertical elevations were measured using a survey level and rod. Horizontal 

measurements were made with a stretched surveyor tape or range finder. The time at the water line was 

recorded so tidal corrections could later be made. Physical and biological characteristics were recorded 

for each across-shore section. The amount of the intertidal zone exposed at each site varied depending on 

when in the tide cycle it was sampled and where the site was located. For example, the tide level in Wide 

Bay (as predicted by the NOAA Tides and Current web site) when it was sampled was -0.7 feet, but was -

2.55 feet on Chowiet Island when the ground team sampled there. The tide height directly influences the 

biobands exposed during the survey so can influence the data collected and comparisons to beaches of 

similar habitat and wave exposure which is why direct comparisons are not usually made.

Bioband boundaries were mapped and labeled on the profile sketch such that their relative position along 

the profile was reflected (vertically and horizontally), with the potential for bands to overlap. Detailed 

photographs were taken of each bioband to reflect species assemblages. It should be noted that bioband 

observations on the ground can be different from aerial observations as the patterns that appear clearly 

from the air may not be so obvious on the beach. Within each bioband, observed species were identified 

to the lowest taxonomic level along a 10 m swath on either side of the transect with an estimate of relative 

abundance. These abundance estimates were scaled to the size of individual organisms and their ecology. 

For example, a dozen Sunflower Stars (Pycnopodia helianthoides) in the swath would be considered 

abundant, whereas it would take many thousands of the Acorn Barnacles (Balanus glandula) in the same 

area to be considered abundant. The relative abundance categories used were: 

• Abundant: the organism occurs in large numbers throughout most of a band.

• Common: the organism is present in moderate numbers throughout most of a band. Few: the 

organism occurs sporadically or in small patches within a band. 

• Rare: only a few isolated individual of the organism occur in a band. 

To provide more quantitative information to the ShoreZone mappers on bioband indicator species and 

assemblages, quadrat percent cover data (up to five quadrats per bioband) were collected when time 

allowed. If time precluded sampling five quadrats for each bioband, collections were prioritized for those 

biobands with the most complex species assemblages or that most difficult to identify from aerial 

imagery. Quadrats were randomly tossed roughly five meters apart along the band. Percent cover of each 

algal and non-motile invertebrate species was recorded within the gridded 0.25m2 quadrat frame. Motile 

invertebrates within each quadrat were also counted.

A sample of each algal species was collected, pressed and vouchered for taxonomic identification and 

archiving at the University of Vancouver and NOAA Auke Bay Laboratories herbaria. A complete 

taxonomic listing of seaweeds and seagrasses and a digital collection of all pressed specimens are 

provided in a NOAA Technical Memorandum (Lindeberg and Lindstrom, 2018). 

Site data were entered in the standard Alaska ShoreZone ground station MS Access database. All data 

were reviewed following data entry for accuracy and completeness. Taxonomists reviewed the species 

lists and corrected misidentifications from the field, based on vouchered specimens and photographs.

During the two ground station surveys we identified 252 unique taxa, including 114 invertebrates, 130 

algal species, 2 seagrasses, and 6 forbs, grasses, and lichens. Though boulders were not overturned to 

look for intertidal fish, an additional 4 taxa were observed during the survey when fish were encountered 

in tide pools, in cobble, or between boulders. A complete list of species identified for each site are 

presented in Appendix C (Table C-1). Since species could occur in more than one bioband on a site, data 

in Appendix A are organized by major taxonomic groupings instead of by bioband. These groupings 

include the green algae (Phylum Chlorphyta), brown algae (Phylum Ochrophyta, Class Phaeophyceae, 

excluding Order Laminariales), Kelps (Order Laminariales), red algae (Phylum Rhodophyta, excluding 

Orders Corallinales and Hapalidiales), invertebrates (Phyla Annelids, Arthropoda, Platyhelminthes, 

Porifera, Echinodermata, Cnidaria, and Mollusca), seagrasses (Phylum Anthophyta), Lichens (Phylum 

Ascomycota), Grass (Leymus mollis), and forbes (Glaux maritima and Senecio pseudoarnica). Species 

are listed alphabetically within each group. Quadrat data are presented in Appendix C (Table C-2) and 

show percent cover for algae and sessile invertebrates, and counts for mobile invertebrates.

Narrative descriptions of the geomorphology and biological attributes observed in-situ for each shore 

station are presented in Appendix D. Also shown are satellite images with shore station locations and 

aerial images showing the exact transect locations. Biological observations are organized by intertidal 

biobands with observations of flora and fauna. The narrative for each site includes photos highlighting

geomorphology, biobands, marine algae, and invertebrates. Note that a ‘Bare’ bioband does not mean that 

there were no species present. This bioband reflects a splash zone devoid of a distinct black seaside lichen 

(Verrucaria sp.) and typically appears as unpopulated gray, black, or white rock or gravel, but may 

include species not identifiable from aerial imagery. If present, these organisms typically include 

scattered invertebrates and small patches of algae. 

 

5.3 Discussion

All Alaska ShoreZone ground station data has been posted online by NOAA’s Alaska Regional Office 

and is available from the online portal. On the portal, species lists by bioband can be viewed and 

downloaded along with site profiles that place biobands within relative tidal elevations. The data can be 

viewed, compiled, and downloaded by shore stations, biobands within shore stations, shore station 

groupings, by a specific region (e.g. Alaska Peninsula), and by combined regions (e.g. Gulf of Alaska). 

All data collected in the Alaska Peninsula will be amalgamated into this online data portal.

This survey was the most extensive survey of intertidal species reported for this section of the Alaska 

Peninsula coast. The shore station survey provided a rare opportunity to conduct a comprehensive 

assessment of marine species occurring in a range of habitats across the littoral zone (including the splash 

zone, intertidal zones, and the very shallow subtidal). The suite of shore stations represents a diversity of 

habitats and wave exposures and provides a species list that is representative of epifaunal species along 

the shorelines of the study area. There is little historical information for intertidal species assemblages 

within the study area, providing few opportunities to compare the shore station species lists to those 

reported in other studies; however, a long-term intertidal monitoring study near the study area provides 

the opportunity to assess shore station survey methods for documenting species presence. The Southwest 

Alaska Inventory and Monitoring Network (SWAN) maintains a series of sites along over 500 km of the 

Katmai and Kenai Fjords National Park coastlines (Dean et al. 2014). From 2006-2014 these sites were 

surveyed almost yearly. Data from these 28 sites showed 103 unique algae and invertebrate taxa on rocky 

habitat (bedrock and gravel) and 129 taxa for all habitats including soft sediment habitats. Along a section 

of coastline overlapping the SWAN Katmai study area, ShoreZone shore station surveys were conducted 

by Archipelago Marine Research Ltd in 2003 and 2009. These data are available on the ShoreZone shore 

station online portal. A combined total of 46 sites were surveyed, once each, and 193 unique alage and 
35

invertebrate taxa for rocky and soft sediment habitats were documented. When this is compared to the

246 unique invertebrate and algal taxa documented at the 27 shore station sites in our Alaska Peninsula

survey it is clear that ShoreZone shore station survey methods are effective at providing comprehensive 

inventories of intertidal species across a range of habitats.

 

Another comparison can be made to the ShoreZone ground station data from the area which represents

116 sites along more than 5000 km shoreline that encompassed Kodiak, Afognak, Shuyak, Sitkalidak, 

Sitkinak, and Perevalnie islands. During those surveys, conducted in 2005, there were 141 unique 

identified algal and 180 unique identified invertebrate species for a total of 321 taxa, compared with 246

species reported for the Alaska Peninsula survey. The difference could be due to the higher number of 

stations sampled, but may be due in part to regional differences in shoreline aspect and wave exposure. 

Shore stations on Kodiak were sampled around the entire circumference of that island archipelago, 

including sites along Shelikof Strait on the western side and the Gulf of Alaska to the east. The suite of 

sites represented north-, south-, east-, and west-facing shorelines while the majority of the Alaska 

Peninsula shoreline faced mostly to the southeast. An additional factor potentially influencing differences 

between the Kodiak archipelago and both the Alaska Peninsula and Katmai areas could be differences in 

input of freshwater to the nearshore. The Alaska current hugs the coastline, with a stronger component 

following along the Katmai and Alaska Peninsula coast than the Kodiak coastline. Glacier ice melt can 

depress intertidal biotic communities by introducing turbidity and freshwater stresses (Peterson 2005). 

The Katmai coast is also somewhat in the lee of Kodiak Island so has some protection from major storms 

from the southeast, while both the east side of Kodiak and the Alaska Peninsula study area would be 

strongly influenced by strong onshore winds. These winds have the potential to mix the water column and 

bring deeper saline, nutrient-rich water to the surface. 

The updated Alaska shore station database with May 2016 Alaska Peninsula data provides information 

that can be compiled and assessed at the site level and at different regional scales. However, the Alaska 

shore station master database must be further updated to incorporate the numerous taxonomic revisions 

made to invertebrate and algae species since the first shore Gulf of Alaska station survey in 2002. The 

Alaska Peninsula dataset provides an impetus for updating the master database and improving website 

capabilities. Species assemblages at hundreds of shore stations in the Gulf of Alaska could be compared 

at various taxonomic and spatial scales if the database included a tool to extract and normalize data to 

account for varying sampling tidal ranges. Subsequent multi-variate analyses of the most complete 

datasets along the Kenai Peninsula, Katmai National Park, Alaska Peninsula, and Kodiak Island 

Archipelago might provide insight into what are the main drivers of intertidal diversity and richness in the 

western Gulf of Alaska.

5.4 Expanded Bioband Table

The ground station data collected in the survey area was provided to the ShoreZone biophysical mappers 

to assist in interpretation of the aerial imagery. The ground station data also allows us to create a bioband 

table with actual indicator and associated species for the common biobands in the Alaska Peninsula 

survey area. This expanded bioband table is found in Table 7.

6 Aerial Imaging and Ground Station Data Comparison

The goal of ShoreZone is to provide first responders, managers and researchers with a descriptive 

overview of the geomorphology and biology of the shoreline from the splash zone to the subtidal. It is 

therefore important to know if the aerial imagery collected in ShoreZone surveys was interpreted

consistently and accurately. Consistency among mappers is addressed by an internal QAQC process 

where mappers review 10% of each other’s work and discuss or correct discrepancies. The accuracy of 

the data interpreted from ShoreZone imagery is generally measured by comparison to shore station data 

collected during ground surveys. Shore station data used for this purpose has primarily been transectbased, in which a cross-shore profile is completed with a basic description of the substrate and a listing of 

the algal and invertebrate species that make up the biobands adjacent to each transect. The algal and 

invertebrate species found on these transects are then used to define the ‘Associated Species’ for each 

bioband, as discussed in the previous section. 

While this methodology has worked well in previous surveys, we decided to develop a different 

techniques for this project. In the past we compared the ground survey transect to the ShoreZone unit in 

which the transect was located which meant comparing different spatial scales (a small swath compared 

to a broad expanse of beach). For this project, we defined small homogenous ground units during the field

survey which were then classified using the aerial imagery in the office. This meant the same area was 

classified both from the ground and from the air and ensured that all classifications were directly 

comparable. It should be noted, however, that observations made from the ground will always differ 

somewhat from observations made using aerial imagery. This verification survey focused on defining the 

differences in the observations at the two different scales so the datasets can be interpreted appropriately.

The ground verification sites were completed during the field survey conducted in May 2016 in 

partnership with Sue Saupe at the Cook Inlet Regional Citizens Advisory Council (CIRCAC). The results 

of that survey are presented in Section 5 of this report. The verification sites were completed by Coastal 

and Ocean Resources (CORI) and were adjacent to the transect sites chosen for the ground stations. The 

start and end coordinates of the site were recorded by the field verifier as they walked the shoreline.

Those boundaries were then marked on the corresponding high-resolution aerial still image and given to 

CORI physical and biological mapping technicians to classify. See example of ground verification unit in 

Figure 24 below. 

The attributes classified by both the field verifier and the office classifier were Intertidal Zone Slope, 

Intertidal Zone Width and Substrate (Primary, Secondary and Tertiary/Interstitial). These attributes were 

classified over the entire intertidal zone. The office classifier was not allowed to see the classification 

done in the field prior to their own classification to preserve the rigor of the comparison. 
42

Figure 24. Example of still image of ground verification unit AKP16_018.

The office and field classifications were put in an Excel spreadsheet and the attributes were scored using 

the criteria shown in Table 8. For this system, it is assumed the field classification is most accurate and it 

is the office classification that is being scored as the same or different. The spreadsheets with the

classified attributes and the scores are found in Appendix E. The scores were summed for each site, 

giving an idea of how similar the field classification was to the office classification. The lower the score, 

the more similar the ground and office classifications.

The overall scores for the 26 verification sites completed during the May 2016 ground station survey are 

presented in Table 9. The rank for each site was based on the following criteria: 0-4 indicates a Match 

between the office and field classification, 5-8 indicates the office and field classification were Similar 

with a few significant differences, and >8 was a Mismatch between the office and field classifications.

Half the sites were ranked as a Match between the field and office classification while half were ranked 

Similar, and no sites were ranked as a Mismatch. For those sites that were ranked Similar the main 

differences between the field and office classifications were:

• The tertiary substrate was the most commonly mismatched, which is unsurprising since there may 

be more than just three substrates, so deciding which is the third most abundant is a judgement 

call. Also, the tertiary substrate may be interstitial or underlying the primary and secondary 

substrates and is therefore harder to assess from aerial imagery than the more abundant substrates.

• The Intertidal Zone Slope category was rarely off by more than one category.

• The Intertidal Zone Width is still the most problematic attribute despite the inclusion of the 

orthophotos created using Structure from Motion (SfM). The lack of ground control points during 

the image collection makes taking measurements from orthophotos more challenging, especially 

on complex and constantly changing shorelines such as those found in the Alaska Peninsula. We 

are currently working on ways to both collect the imagery and process it with the SfM software to 

make the measurement of intertidal width more accurate.

• Biobands were generally similar, with those most often missed by either the office classifier 

being the Barnacle, Green Algae and Bleached Red Algae bands. This is unsurprising since those 

bands often overlap with each other and with the Rockweed and Filamentous and Foliose Algae 

bands which tend to be more obvious in the areal imagery. It should be pointed out that green and 

red algal and barnacle species are defined as associated species with both the Rockweed and 

Filamentous and Foliose Red biobands, so while those groups may not appear as biobands from 

the air, the species themselves are considered to be present on the beach.

• The weather often was cloudy and rainy, making the survey challenging and the imagery dark. 

This made identification of the substrates and biobands from the aerial imaging challenging at 

times.

line shows location of transect where site profile was measured
206

Site AKP_16_001 was located on the east side of Wide Bay, on the northwestern side of an islet, between 

Slaughter Island and Hartmen Island (Figure D-1; Figure D-2). The site was characterized by a semiexposed vertical cliff and wide bedrock platform with gravel beach (Figure D-3; Photo A). The substrate 

was classified as partially mobile, current and sea swell influenced the site as noted by semi-rounded 

boulders. The upper intertidal zone had patchy flora and fauna, except within tide pools. The lower 

intertidal zone was lush with red, green and brown seaweeds, with few invertebrates observed. In the 

nearshore, bands of ribbon kelp (Alaria marginata), soft brown kelp and bull kelp (Nereocystis 

luetkeana). 

Site AKP_16_001 consisted of a vertical bedrock wall above the high-water line. The intertidal zone was 

approximately 50 m in width, with a low gradient slope (<5°) to the waterline (Figure D-3; Photo B). In 

the upper intertidal zone, large boulders over bedrock dominated the substrate for approximately 30 m. In 

the lower intertidal zone, the substrate consisted of small boulders and cobbles over 20 m wide bedrock 

platform.

Splash Zone bioband: The supratidal zone consisted of a wide band of black seaside lichen (Verrucaria

sp.) with patches of orange seaside lichen (Caloplaca/Xanthoria sp.). In addition, patches of green rock 

scum (Rosenvingiella polyrhiza) and olive green winter laver (Pyropia pseudolanceolata) were 

documented. Common splash zone invertebrates included the Sitka periwinkle (Littorina sitkana) and 

mask limpets (Tectura persona).

Bare bioband: Patches of Caloplaca/Xanthoria sp., P. pseudolanceolata and R. polyrhiza were 

documented. Common invertebrates in the bioband included L. sitkana and T. persona. 

Barnacle bioband: A wide distribution of thatched barnacle (Semibalanus cariosus) and acorn barnacle 

(S. balanoides) were documented, along with an abundance of L. sitkana (Figure D-3; Photo C). During 

the quadrat survey, percent cover of S. cariosus ranged from 1-50% in all 5 quadrats. Counts of L. sitkana 

ranged from 60-1000 individuals in four out of five (4/5) quadrats. Patches of Turkish washcloth complex 

(Mastocarpus alaskensis), studded sea balloons (Soranthera ulvoidea), and graceful black pine 

(Neorhodomela aculeate) were distributed along the bioband. Quadrat data identified rockweed (Fucus 

distichus) ranged from 10-15% in 3/5 quadrats. Lower in the bioband, tide pools provided habitat for red 

coralline algae species (encrusting and articulating), rockweed tuft (Elachista fucicola), sea brush 

(Odonthalia floccosa), and sea fungus (Ralfsia fungiformis) (Figure D-3; Photo D). 

Red Algae bioband: This lower intertidal bioband was wide and continuous, with a mix of red, green, and 

brown algae. Red algae species dominating the bioband included red ribbon (Devaleraea spp.; 5-40% 

cover in 5/5 quadrats), Mastocarpus sp. (1-20% cover in 5/5 quadrats), and O. floccosa (Figure D-3; 

Photo E). Common green algae species included green rope (Acrosiphonia coalita; 1-15% cover in 3/5

quadrats) and sea lettuce (Ulva lactuca; 1-25% cover in 4/5 quadrats). Observations of sea stars 

(Evasterias troschelii, Henricia leviuscula and Pycnopodia helianthoides) and dorid nudibranchs were 

recorded. 

Nearshore biobands: Three biobands were present in the nearshore and included a patchy, narrow Alaria 

bioband, a moderate band of Soft Brown Kelps and a narrow, continuous band of Bull Kelp (Figure D-3; 

Photo F). 
207

Photo A: The site was characterized by a semiexposed vertical cliff with a wide bedrock platform with 

gravel beach.

Site AKP_16_002 was located in Wide Bay, on the western tip of Slaughter Island (Figure D-4; Figure D5). The site consisted of a vertical bedrock cliff with wide bedrock platform that was classified as semiexposed with immobile substrate. Both the ocean current and sea swell influence the site morphology as 

evidenced by polished bedrock in upper intertidal. The upper intertidal zone was mostly bare of flora, but 

a thick, wide barnacle band was present. The lower intertidal zone was lush, with almost 100% epifaunal 

cover along the entire Red Algae, Alaria, and Dark Brown Kelp biobands. Just offshore was a narrow 

Bull Kelp bioband. Site AKP_16_002 consisted of a high, vertical bedrock wall above the high-water 

line. The intertidal zone was characterized by a wide bedrock platform spanning 68 m in width, with a 

low gradient slope (4°) to the waterline (Figure D-6; Photo A). The upper intertidal zone was 18 m wide 

with scattered boulders and cobbles on the bedrock. The lower intertidal zone was 50 m wide with large 

boulders over bedrock. 

Splash Zone bioband: The supratidal zone consisted of a medium (4 m) patchy band of black seaside 

lichen (Verrucaria sp.) and a wide patchy band of orange seaside lichen (Caloplaca/Xanthoria sp.). 

Winter Laver bioband: Patches of red algae laver (Pyropia sp.) and black sea hair ("Bangia" spp.) were 

identified (Figure D-6; Photo B). In the quadrat survey, four quadrats were placed in this bioband. 

Pyropia sp. ranged from 10-60% cover in 3/4 quadrats. "Bangia" spp. ranged from 10-40% in 3/4 

quadrats. Invertebrates common to the higher intertidal zone included shield limpets (Lottia pelta) and the 

Sitka periwinkle (Littorina sitkana). 

Barnacle bioband: A continuous and wide distribution of acorn barnacles (Semibalanus balanoides and 

Balanus glandula) dominated this bioband (Figure D-6; Photo C). In the quadrat survey, B. glandua 

ranged from 3-30% cover in 2/5 quadrats while Balanamorpha ranged from 10-90% cover in 2/5 

quadrats. Patches of the red alga, Oregon pine (Neorhodomela oregona), were present in the lower 

portion of this bioband. Quadrat counts of L. sitkana ranged from 60-250 individuals in 4/5 quadrats. 

Red Algae bioband: This bioband consisted of a thick continuous mix of red, green, and brown algae. 

Along the upper parts of the bioband, N. oregona (10-20% cover in 4/5 quadrats) was present, while the 

red algae, sea brush (Odonthalia floccosa; 10-60% cover in 5/5 quadrats), fominated in the lower band. 

Tide pools scattered the bioband’s bedrock substrate and provided habitat to several anthozoan species 

including plumose anemone (Metridium senile), red bead anemone (Urticina coriacea), and painted 

anemone (U. grebelnyi). Other marine invertebrates present included the chitons, black katy chiton 

(Katharina tunicata) and red lined chiton (Tonicella lineata), and the six-armed sea star (Leptasterias 

spp.). 

Alaria bioband: A thick, continuous band of ribbon kelp (Alaria marginata; 10-98% cover in 5/5 

quadrats) was observed in the bioband in addition to the common red ribbon alga (Devaleraea sp.; 5-45% 

cover in 5/5 quadrats), Turkish washcloth complex (Mastocarpus sp.; 5% cover in 1/5 quadrats), and 

laver species (Pyropia sp.; 1-10% cover in 3/5 quadrats) (Figure D-6; Photo D). Dense patches of the 

Pacific blue mussel (Mytilus trossulus) were scattered throughout the bioband (Figure D-6; Photo E). 

Dark Brown Kelp bioband: This continuous bioband was dominated by brown bladed kelps, including

split kelp (Saccharina nigripes), five-ribbed kelp (Costaria costata), three-ribbed kelp (Cymathaere 

triplicate), and A. marginata (Figure D-6; Photo F). Common red algae found in the bioband included 

corallines, Northern mazza weed (Mazzaella phyllocarpa), and Mikami’s sea oak (Mikamiella 

ruprechtiana).

Site AKP_16_004 was located on the western coast of Nakalilok Bay (Figure D-10; Figure D-11)

adjacent to Site AKP_16_003. The site consisted of a wide, low gradient boulder beach over bedrock 

platform. The site was classified as semi-exposed, with partially mobile substrate, as evidenced by the 

well-rounded rounded bare boulders in the higher intertidal zone. In the upper- and mid- intertidal zones 

wide Splash Zone, Bare, and Barnacle biobands were present (Figure D-12; Photo A). A bedrock ramp 

was exposed in the mid-intertidal zone. The lower intertidal zone contained wide biobands of Rockweed, 

Red Algae and Dark Brown Kelps on rounded boulders. A narrow bioband of Bull Kelp was observed

just offshore of site. Site AKP_16_004 was characterized by a 106 m wide low gradient boulder beach, 

with an overall slope of 2.5°. The 67 m upper intertidal zone consisted predominantly of smaller boulders, 

with cobble and shallow tide pools. The 39 m wide lower intertidal zone had medium to large boulder, 

most with close to 100% vegetation cover. 

Splash Zone bioband: The supratidal zone consisted of a distinct, continuous band of black seaside lichen 

(Verrucaria sp.) covering most boulders. Common invertebrates were beach hoppers (Traskorchestia 

traskiana) and Sitka periwinkle (Littorina sitkana). 

Bare bioband: The band spanned approximately 34 m and consisted of a mixture of boulders over 

bedrock with tide pools. Marine flora was sparse and included the red filamentous seaweed, black sea hair 

("Bangia" spp.), graceful black pine (Neorhodomela aculeata), and encrusting coralline algae.

Barnacle bioband: The Barnacle bioband was 19 m in width with a composition of substrate and flora 

similar to the Bare bioband. Barnacle coverage was sparse at only 1-30% in the three quadrat plots. 

Common high intertidal invertebrates included L. sitkana (20-50 count in 3/3 quadrats) and limpets 

(Lottia sp.). Tidepool sculpin (Oligocottus maculosus) and serrulated surfgrass (Phyllospadix serrulatus) 

were common (Figure D-12; Photo B) in the tidepools. 

Rockweed bioband: The band consisted predominantly of rockweed (Fucus distichus; 25-35% cover in 

3/4 quadrats). Red algae were also observed and included sea brush (Odonthalia sp.; 10-15% in 2/4 

quadrats), Pyropia sp. (laver; 5-25% cover in 4 quadrats), and red ribbon (Devaleraea mollis; 1-20%

quadrats) and green rope (Acrosiphonia coalita), and the brown algae, soda straws (Scytosiphon 

lomentaria) (Figure D-12; Photo C). Marine invertebrates included black katy chiton (Katharina 

tunicata), Margarite snail (Margarites sp.), Pacific blue snail (Mytilus trossulus), and mask limpet 

(Tectura persona). During low tide, a red fox (Vulpes vulpes) was observed foraging for invertebrates 

(Figure D-12; Photo D) and eating several K. tunicata. 

Red Algae bioband: The bioband was dominated by a thick, continuous layer of foliose red algae 

(Odonthalia sp.; 60-95% cover in 3/3 quadrats) (Figure D-12; Photo E). Encrusting coralline algae (5-

40% cover in 3/3 quadrats) was observed below the other red algae. Marine invertebrates were diverse

and included three seastars, the blood star (Henricia leviuscula), sunflower star (Pycnopodia 

helianthoides), and leather star (Dermasterias imbricata), and two anemones, the green anemone 

(Anthopleura sp.) and plumose anemone (Metridium sp.). Marine molluscs included white capped limpet 

(Acmaea mitra), Oregon triton (Fusitriton oregonensis), Margarites sp., K. tunicata, and orange fragrant 

nudibranch (Peltodoris nobilis). 

Dark Brown Kelp bioband: This continuous band was dominated by the brown bladed kelps, southern 

stiff-stiped kelp (Laminaria setchellii), Northern rhizome kelp (L. longipes), five-ribbed kelp (Costaria 

costata) and split kelp (Saccharina nigripes) (Figure D-12; Photo F). Common red algae included sea 

fern (Ptilota asplenioides), Russian sea brush (O. setacea), bladed red alga (Devaleraea sp.), black tassel 

(Polyostea bipinnata), and red eyelet silk (Sparlingia pertusa). When sampled, this bioband was

221

Site AKP_16_006 was in the Semidi Islands group, on the northwestern coast of Chowiet Island (Figure 

D-16; Figure D-17). The site consisted of a wide, low gradient beach with medium to large rounded 

boulders dominating the lower intertidal zone and large rounded cobble and small boulders on the beach 

face (Figure D-18; Photo A). The site was classified as semi-exposed with partially mobile substrate. Sea 

swell influences site morphology as evidenced by the well-rounded boulders and cobbles. Terrestrial 

grasses and woody debris were observed above the Splash Zone bioband (Figure D-18; Photo A). The 

upper intertidal zone consisted of Bare and Green Algae biobands. The lower intertidal zone contained 

relatively high algae diversity, with wide, continuous Red Algae and Dark Brown Kelp biobands. Though 

wave energy influences the beach, vegetation cover on tops of boulders indicates that it is not high 

enough to preclude attached epifauna in the lower zones. A narrow band of Bull Kelp was observed just 

offshore. 

Site AKP_16_006 was characterized by a wide, low gradient boulder and cobble beach. The Splash Zone 

bioband consisted of large angular boulders. From the Bare bioband to the water, substrate was comprised 

of rounded boulders and cobbles. The Green Algae bioband spanned 14.5 m, the Red Algae bioband 

spanned 11.6 m, and the Dark Brown Kelp bioband spanned 7 m. Combined, the 33.1 m mid- to low 

intertidal zone spanned had an overall slope of 6.7°.

Supratidal zone: The high intertidal zone consisted of a Splash Zone bioband and a Bare bioband. Above 

the supratidal zone, terrestrial grasses and logs were present. The Splash Zone consisted of a patchy band 

of black seaside lichen (Verrucaria sp.) and sparse cover of laver (Pyropia sp.) over angular rocks. 

Seaweed drift and woody debris were recorded in the supratidal zone. There were no observations of 

fauna.

Green Algae bioband: The bioband consisted of a patchy distribution of the green filamentous algae, 

Ulothrix sp., and Acrosiphonia sp. (1-20% cover in 2/3 quadrats) (Figure D-18; Photo B). Red algae 

distribution was also patchy and included Turkish washcloth complex (Mastocarpus sp.; 1-10% cover in 

all 3 quadrats), stiff ribbon (Palmaria hecatensis; 1-10% cover in 2/3 quadrats), and laver (Pyropia sp.). 

Invertebrates were limited to common Sitka periwinkle (Littorina sitkana; approximately 20 individuals 

in 1 quadrat). 

Red Algae bioband: Algae richness was high in the Red Algae bioband amd the dominant species 

included the red algae Turkish washcloth complex (Mastocarpus sp.; 60% cover in 1/3 quadrats), massa 

weed complex (Mazzaella sp.; 30% cover in 1/3 quadrats), P. hecatensis (15-50% cover in 3/3 quadrats), 

and sea sac (Halosaccion glandiforme) (Figure D-18; Photo C). Patches of bladed brown kelps included 

ribbon kelp (Alaria marginata; 5-30% cover in 3/3 quadrats) and split kelp (Saccharina nigripes) (Figure 

D-18; Photo D). Green algae included the filamentous Acrosiphonia sp. (1-5% cover in 3/3 quadrats) and 

foliose sea lettuce (Ulva sp.; 5% cover in 1/3 quadrat). There were no observations of marine 

invertebrates in this bioband. 

Dark Brown Kelp bioband: The bioband was dominated by two bladed kelp species, split kelp 

(Saccharina nigripes; 25-80% cover in 2/5 quadrats) and Northern rhizome kelp (Laminaria longipes; 5-

80% in 4/5 quadrats) (Figure D-18; Photo E). A variety of red algae were also commonly encountered, 

including filamentous red algae (Ptilota sp.; 25-50% cover in 4/5 quadrats), red ribbon (Devaleraea 

mollis; 1-15% cover in 4/5 quadrats) and encrusting and articulating coralline algae (20-60% cover in 4/5 

quadrats). In addition, diatoms covered the Ptilota sp. (Figure D-18; Photo E). Few invertebrates were 

encountered within the bioband and were limited to grazers such as red lined chiton (Tonicella lineata), 

shield limpet (Lottia pelta), and white capped limpet (Acmaea mitra). 

Bull Kelp bioband: A narrow, continuous band of bull kelp (Nereocystis luetkeana) and few strands of 

dragon kelp (Eualaria fistulosa) were observed just offshore.

site was complex, consisting of a wide, mixed substrate beach with a bedrock outcrop in the mid- to lower 

intertidal zone. The site was classified as semi-exposed with partially mobile substrate. Sea swell 

influences the site morphology. In the upper intertidal zone, a Bare bioband was present with substrate 

consisting of sand, cobble, and boulders in the upper band transitioning to a bedrock platform in the midto lower portion. The Rockweed bioband consisted of a bedrock reef feature with shallow tide pools. A 

lush Rd Algae bioband, mixed with surfgrass, and a Dark Brown Kelp bioband were observed in the low 

intertidal. A Bull Kelp bioband was just offshore. 

Site AKP_16_007 was characterized by a wide, low gradient beach spanning approximately 116 m in 

width, with an overall slope of 2.7° (Figure D-21; Photo A). The supratidal zone consisted of a log line 

over sand, cobble, and boulder substrate for 6 m. The Bare bioband was approximately 33 m wide, with 

substrate mixed sand, cobble, and boulder transitioning to a bedrock platform towards the waterline. The 

Rockweed bioband spanned 51 m in width. Geomorphic features included shallow tide pools and a basalt 

reef outcrop (Figure D-21; Photo B). The Red Algae bioband was approximately 27 m wide on a bedrock 

platform where tide pools were also present. 

Bare bioband: The supratidal zone consisted of a wide log line over mobile substrate comprised of 

boulder, cobbles and sand (Figure D-21; Photo C). Approximately midway through the bioband, substrate 

transitioned to bedrock. Although no marine fauna or flora was observed, pockets of seaweed drift were 

present. 

Rockweed bioband: The wide bioband had a patchy distribution of rockweed (Fucus distichus) that 

ranged from 1-30% cover in 3/6 quadrats (Figure D-21; Photo D). A mix of filamentous red algae 

included sea brush (Odonthalia floccosa; 1-50% cover in 2/6 quadrats; Figure D-21; Photo D), rockweed 

brush (O. floccosa f. comosa; 3-40% cover in 4/6 quadrats), and black tassel (Polyostea bipinnata; 10%

Site AKP_16_009 was on the north shoreline inside Port Wrangell (Figure D-25; Figure D-26). The site 

consisted of a steep bedrock cliff which transitioned to a narrow, benched, bedrock ramp (Figure D-27; 

Photo A). The site was classified as semi-exposed with immobile substrate. Sea swell and currents 

influence morphology. The upper intertidal zone consisted of narrow Splash Zone, Bare, and Barnacle 

biobands. The lower intertidal zone consisted of Blue Mussel, Rockweed, Alaria, and Dark Brown Kelp 

biobands. Species richness was relatively high at this site, and tide pools within the bedrock ramp 

scattered the intertidal zone. In the nearshore, a patchy Bull Kelp bioband was observed. 

Site AKP_16_009 was characterized by a vertical bedrock wall which transitioned into a narrow bedrock 

ramp to the waterline. The upper intertidal zone was 2.20 m in height on the bedrock wall and consisted 

of a Splash Zone, Bare, and Barnacle bioband. The Blue Mussel band spanned the bottom of the bedrock 

cliff and covered 2.7 m of the bedrock ramp. The overall bedrock platform was narrow, at 20.6 m wide 

and the mid- to lower intertidal zone included Rockweed, Alaria, and Dark Brown Kelp biobands. The 

upper bedrock platform had shallow tide pools and deeper tide pools were present in the Alaria and Dark 

Brown Kelp biobands (Figure D-27; Photo A). 

Splash Zone bioband: The high intertidal zone consisted of a continuous, medium width black seaside 

lichen (Verrucaria sp.) bioband on vertical bedrock.

Barnacle bioband: A continuous and narrow distribution of acorn barnacles (Balanus glandula) and small 

brown barnacles (Chthamalus dalli) dominated the bioband. Barnacles were also present in all three 

quadrats, B. glandula ranged from 5-20% cover, while C. dalli ranged from 5-30%. Limpets (Lottia sp.), 

Pacific blue mussles (Mytilus trossulus), and Sitka periwinkles (Littorina sitkana) were present. Common 

high intertidal algae included sea moss (Endocladia muricata), black sea hair ("Bangia" spp.), rockweed 

laver (Pyropia fucicola), and green rock scum (Rosenvingiella polyrhiza). 

Blue Mussel bioband: The Blue Mussel bioband originated at the base of the bedrock cliff and 

transitioned to the bedrock ramp. The bioband consisted of a mix of the Pacific blue mussel (M. 

trossulus), the brown alga rockweed (Fucus distichus), and the red algae sea brush (Odonthalia floccosa), 

and Polyostea sp. (Figure D-27; Photo B). Three quadrats were sampled in the Blue Mussel bioband with 

the following present in all three; M. trossulus (10-30% cover), Polyostea sp. (20-70% cover), and O. 

floccosa (1-40% cover). Shallow tide pools provided habitat to L. sitkana, plumose anemone (Metridium

Site AKP_16_017 was located at the eastern entrance of Castle Bay, near Chignik Bay (Figure D-49; 

Figure D-50). The site was composed of large, angular boulders overlying a bedrock platform. The site 

was classified as semi-exposed with immobile substrate. The Splash Zone was continuous and wide. The 

upper intertidal zone consisted of continuous Winter Laver and Rockweed biobands, while the lower 

intertidal zone consisted of a lush Red Algae bioband. Tide pools provided habitat to numerous 

invertebrates and encrusting coralline algae. Quadrat data were not collected at this site.

Site AKP_16_017 consisted of a soft sediment cliff wall above the high water line. From the Splash Zone 

to the water line, substrate was composed of a mix of angular rubble (in higher intertidal) and semirounded large boulders intermixed with angular cobbles and pebbles across the beach, all overlying a 

bedrock platform (Figure D-51; Photo A). The beach face was approximately 31 m in width, with the 

upper intertidal zone spanning 16.5 m and the lower intertidal zone spanning 6.0 m. The exposure, fetch, 

rounding of large rubble in the low intertidal, and the biota all indicate a relatively high energy beach. 

The angular cobble in the upper beach indicates an actively eroding bluff. 

Splash Zone bioband: The supratidal zone consisted of a continuous band of black seaside lichen 

(Verrucaria sp.) (Figure D-51; Photo B). Common invertebrates associated with the high splash zone

Site AKP_16_019 was located on the south coast of Chignik Bay, near the mouth of Anchorage Bay 

(Figure D-55; Figure D-56). The site was classified as semi-exposed with partially mobile substrate. The 

beach face consisted of a huge vertical bedrock cliff above the high water mark, with a wide, low gradient 

bedrock platform covered in cobbles and boulders to the waterline. These rocks were mostly highly 

rounded. However, spherical rocks were seen eroding from the cliff making it unlikely that wave energy 

is rounding the rocks. The upper intertidal zone consisted of Green Algae, Bare and patchy Rockweed 

biobands. In the lower intertidal zone, a continuous band of Red Algae was present. Species richness at 

this site was highest in the lower intertidal zone, with a wide variety of fauna and flora observed. In the 

nearshore, a band of coralline red algae was present, which may be an indication of sea urchin barrens1

, 

followed by a narrow Bull Kelp bioband. 

Site AKP_16_019 consisted of a vertical bedrock wall and a low gradient beach face spanning 60 m in 

width (Figure D-57; Photo A). Substrate consisted predominantly of a bedrock platform, though bands of 

boulders and cobbles were present (Figure D-57; Photo B). In the upper intertidal zone, a narrow Green 

Algae bioband covered boulder, cobble, and pebble over bedrock for 3.7 m (Figure D-57; B). A wide 

Bare bioband spanned 17 m with substrate transitioning from boulder to bedrock (Figure D-57; Photo B). 

The Rockweed bioband was patchy and 22.2 m in width, with substrate consisting of bedrock and small 

boulders to the waterline. The lower intertidal zone consisted of a wide, continuous bioband of Red

Site AKP_16_021 was located on the northern coast of Kujulik Bay (Figure D-61; Figure D-62). The site 

consisted of a vertical bedrock cliff above the high supratidal zone and a bedrock platform with boulders 

and cobbles in the intertidal zone (Figure D-63; Photo A). The site was classified as semi-exposed with 

partially mobile substrate. The supratidal zone consisted of a wide, continuous Splash Zone bioband on 

the bedrock wall. The upper intertidal zone consisted of wide Bare, Barnacle and Rockweed biobands 

(Figure D-63; Photo B). In the lower intertidal zone, a narrow Alaria bioband was followed by Dark 

Brown Kelps at the waterline. In the lower intertidal zone species richness was high, with a wide range of 

algae species recorded. Although marine invertebrate species richness was high, abundance of any one 

species was low.

Site AKP_16_020 consisted of a vertical bedrock cliff and a wide, low gradient bedrock platform 

spanning 41.2 m (Figure D-63; Photo A; Photo B). In the upper intertidal zone, the Barnacle and 

Rockweed biobands were wide, extending 14.5 m and 17.1 m respectively. The lower intertidal zone 

consisted of narrow Alaria and Dark Brown Kelps biobands, spanning 5.7 m. While substrate was 

predominantly bedrock, boulder and cobble were present across the beach.

Site AKP_16_022 was located on the southwest coast of Kujulik Bay (Figure D-64; Figure D-65). The 

site was characterized by a low-lying cliff and a wide, low gradient beach consisting of bedrock, boulder, 

and cobble (Figure D-66; Photo A). The site was classified as semi-protected, with partially mobile 

substrate. The supratidal zone was marked by a distinct, continuous Splash Zone bioband. The upper 

intertidal zone consisted of wide Bare, Barnacle, and Rockweed biobands with a Bleached Red Algae 

bioband in the lower intertidal zone. There were no observations of canopy kelps in the nearshore. The 

Bleached Red Algae bioband appears to have bleached more than was shown during the aerial survey of 

the coastline, which took place two weeks prior to when this shore station was sampled.

Site AKP_16_022 consisted of a low gradient, 77.8 m wide beach. Substrate was complex, consisting 

predominantly of bedrock in the Splash Zone and Bare biobands transitioning to boulder, cobble, and 

pebble for the remainder of the beach. The upper intertidal zone was wide at 40.08 m, with Bare, 

Barnacle and Rockweed biobands. Lower in the intertidal zone, a continuous Bleached Red Algae 

bioband spanned the remaining 27 m to the waterline. 

Splash Zone bioband: This band was comprised of a continuous band of black seaside lichen (Verrucaria 

sp.) was recorded. 

Bare bioband: Common to abundant invertebrates in the Bare bioband included the Sitka periwinkle 

Littorina sitkana, beach hopper (Traskorchestia traskiana) acorn barnacle (Semibalanus balanoides) and

sand, pebble, cobble, and small boulders. The site was classified as semi-exposed with partially mobile 

substrate. In the supratidal zone, biobands included a wide Dune Grass band with woody debris and a 

wide Bare band consisting of sand, pebble, and cobble (Figure D-75; Photo A). In the intertidal zone a 

continuous wide band of Green Algae and Surfgrass covering boulder, cobble, and pebble was observed. 

Site AKP_16_025 consisted of a low gradient, wide beach spanning 154.5 m from the base of the dune 

grass to the waterline. In the supratidal zone a log pile had accumulated adjacent to the Dune Grass 

bioband, with substrate consisting solely of sand. A wide Bare bioband was also part of the supratidal and 

high intertidal zone, spanning 60.7 m. Substrate consisted predominantly of sand in the first half of the 

bioband and transitioned to pebble, cobble, and sand in the lower half. In addition, an ephemeral stream 

flowed through the Bare bioband. The mid intertidal zone included a 69.8 m wide Green Algae bioband 

with pooling water and a sand, pebble, cobble substrat (Figure D-75; Photo B). A wide, dense band of 

Surfgrass occurred in the low intertidal zone and extended beyond the waterline (Figure D-75; Photo B,

Algae bioband (16.0 m).

Splash Zone bioband: The splash zone had a wide and continuous band of black seaside lichen 

(Verrucaria sp.).

Bare bioband: Very little fauna were recorded in this bioband, with most having abundance category 

"few." They included Oregon pine (Neorhodomela oregona), rusty rock (Hildenbrandia rubra); Dwarf 

sea hair (Blidingia minima); and twisted sea tubes (Melanosiphon intestinalis). Invertebrate were also 

limited, with low abundance of acorn barnacles (Balanus glandula), the Sitka periwinkle (Littorina 

sitkana), and the mask limpet (Tectura persona). 

Barnacle bioband: The bioband consisted of a wide, continuous band of B. glandula and thatched 

barnacle (Semibalanus cariosus) (Figure D-81; Photo C). Invertebrates ranged from few to common, with 

the most abundant species being L. sitkana having counts ranging from 66-141 individuals in 2/2 

quadrats. Other common ivertebrates were shielf limpets (Lottia pelta), hairy hermit crabs (Pagurus 

hirsutisculus), rockweed idotea (Pentidotea wosnesenskii), and Northern feather duster worms (Eudistylia 

vancouveri). The foliose red algae, black seaweed (Pyropia abbottiae), was also common. Less common 

(rare to few) algae included N. oregona, rockweed (Fucus distichus) and studded sea balloons 

(Soranthera ulvoidea). 

Rockweed bioband: This continuous, wide bioband consisted of a mix of red, green and brown seaweed. 

Laver (Pyropia sp.) ranged from 5-60% cover in 3/4 quadrats. The relative abundances of marine flora 

were otherwise classified as rare to few. These included the brown algae species F. distichus, S. ulvoidea, 

soda straws (Scytosiphonia lomentaria and chocolate pencils (Chordaria flagelliformis). Red algae 

species included rock crust (Clathromorphum sp.), encrusting corallines, and black tassel (Polyostea 

bipinnata; 5-22% cover in 2/4 quadrats). Green sea lettuce (Ulva sp.) was found on bedrock and in tide 

pools. Marine invertebrates included an abundance of S. cariosus and B. glanduala (2-23% cover in 4/4 

quadrats), Lottia sp., L. sitkana, and black katy chitons (Katharina tunicata). Other species ranging from 

rare to few included the painted anemone (Urticina sp.), red lined chiton (Tonicella lineata), hermit crab 

(Pagurus sp.), and blood star (Henricia leviuscula).

Red Algae bioband: In this wide, continuous bioband, common red algae included Kjellman’s laver 

(Wildemania variagata), P. bipinnata, and O. floccosa; while the green algae Ulva sp. was abundant 

(Figure D-81; Photo D, Photo E). Invertebrate included: green anemone (Anthopleura sp.); E. vancouveri, 

C. dalli and S. cariosus in tide pools (Figure D-81; Photo F).

Photo A: Site AKP_16_028 was complex, consisting of a spit 

with sandy beaches on either side. The lower intertidal zone 

had a relatively high number of seaweed and invertebrate 

species. 

Photo B: Looking towards the waterline along the long, narrow 

spit, the substrate consisted of a mix of bedrock, boulder, 

cobble, and pebble.

Photo C: The wide, continuous barnacle band consisted of 

Balanus glandula, Semibalanus cariosus, and patches of 

Fucus distichus and Neorhodomela oregona. 

Photo D: In the intertidal zone a wide, patchy Rockweed 

bioband mixed with the foliose red algae Pyropia sp. was 

present. In the lower intertidal zone a Red Algae bioband 

included a mix of red, brown, and green algae. 

Photo E: In the Red Algae bioband the sea star Leptasterias 

sp. sits atop the red algae Odonthalia floccosa. The foliose 

green algae Ulva sp. and foliose red algae Pyropia sp. can 

also be identified in this image. 

Photo F: In tide pools marine invertebrates included barnacles 

Chthamalus dalli and Semibalanus cariosus, the anemone 

Anthopleura sp., and the tube worm Eudistylia vancouveri.
