AFSC/RACE/GAP/Prescott: Central Gulf of Alaska Multibeam Survey H11118

We assembled 1.75 million National Ocean Service (NOS) bathymetric soundings from 225 lead-line and single-beam echosounder hydrographic surveys conducted from 1901 to 1999 in the central Gulf of Alaska. These bathymetry data are available from the National Geophysical Data Center (NGDC: http://www.ngdc.noaa.gov), which archives and distributes data that were originally collected by the NOS and others. While various bathymetry data have been downloaded previously from NGDC, compiled, and used for a variety of projects, our effort differed in that we compared and corrected the digital bathymetry by studying the original analog source documents - digital versions of the original survey maps, called smooth sheets. There were several areas where these older surveys were superseded by more recent, higher quality multibeam surveys, mostly from the NOS (n=106). Three of these were unprocessed NOS multibeam surveys in the Sitka area, which we edited and processed into final bathymetric surfaces. We reduced the resolution of these multibeam surveys to 100 m, since some may have sub-meter resolution and many exceed a million soundings, and added them to our bathymetry compilation. 
In Sitka Sound survey H11118 was missing. Processing and adding its bathymetric data to our compilation filled in a substantial gap in Sitka area, between Kruzof, Krestof, and Middle islands.

Chukchi and East Siberian Surveys (ChESS): Joint U.S.-Russian Aerial Surveys for Ice-Associated Seals and Polar Bears, 2016

The Chukchi and East Siberian Surveys (ChESS) were a joint U.S.-Russian effort to enumerate ice-associated seals and polar bears in the Chukchi and East Siberian seas. ChESS is a component of the Loss of Sea Ice (LOSI) initiative, which is a multi-disciplinary effort led by the Habitat and Ecological Processes Research (HEPR) Program at NOAA Fisheriesâ Alaska Fisheries Science Center. 

The focus of this project was to provide baseline distribution and abundance data for breeding populations of bearded and ringed seals in the Chukchi Sea and to provide additional polar bear population estimates. Russian colleagues conducted aerial surveys in the western Chukchi and east Siberian seas while U.S. colleagues conducted surveys in the eastern Chukchi Sea. These surveys were designed to occur concurrently using similar methodology.

AFSC/RACE/GAP/McConnaughey: Fishpac Projects-2012-SonarWiz

The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species.  For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf.  Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes.

AFSC/RACE/GAP/McConnaughey: Trawlex Chronic Effects-1996-Other

The eastern Bering Sea has experienced rapid and intensive development of commercial trawl fisheries. Because of good record keeping and the relatively brief history of fishing it is possible to reconstruct the spatial and temporal patterns of exploitation. Previously unfished (UF) areas can be identified and directly compared with heavily fished (HF) areas to investigate long-term consequences for the benthos. Using this approach, macrofauna populations in a shallow (48 m average) soft-bottom area were studied during 1996. Catch data were extracted from the AFSC NORPAC database for years 1973-2001 to provide a summary of trawl catch effort, specific focus was placed on the area within Fisheries Management Area 512. Data were merged with a 1nm grid that covered fisheries management area 512. The total number of hauls were summed for all points falling within each 1nm cell.

Sabine National Wildlife Refuge 1999

Terracing uses existing bottom sediments to form terraces or ridges at marsh elevation and the intertidal zone is planted with marsh vegetation. This study examined the habitat value of terracing at Sabine National Wildlife Refuge, Louisiana in the spring and fall of 1999 by quantifying and comparing nekton densities in a 9-yr old terrace field and nearby reference area using a 1 m2 drop sampler. Using density and biomass patterns and the percentage of marsh and pond area in the terrace field, we concluded that terrace fields support higher standing crops of most fishery species compared with shallow marsh ponds of similar size. Future restoration projects could include design changes to increase the proportion of marsh in a terrace field and enhance the habitat value of marsh terraces for fishery species.

AFSC/RACE/GAP/McConnaughey: Bristol Bay Reconnaissance Study-2002-GIS

Environmental variables that are ecologically relevant and easily measured over large areas are useful for modelling species distributions and habitats. Continuous acoustic, sonar-backscatter data convey information about physical properties of the seabed, and hence could be a valuable addition to that suite of variables. The potential utility of acoustic backscatter was tested for improving habitat models of marine species using data from a pilot sidescan-sonar survey conducted from 28 June to 3 July 2002 in the Bristol Bay region of the eastern Bering Sea (EBS). Raw digital backscatter data were processed with QTC SIDEVIEW and CLAMS software to objectively segment bedform based on statistical analysis of the echograms.  Resultant acoustic variables  - Q-values (Q1, Q2, and Q3)-, representing the first three principal components of the data derived from image analysis of backscatter echoes, and a complexity metric (compx) measuring the variance of Q-values in a geographic area - were used in multiple linear regression to model individual species abundance from bottom-trawl survey data.

A Dataset from Bio-loggers Deployed on Harbor Seals (Phoca vitulina) in Cook Inlet, Alaska (2004-2007)

Between 2004 and 2006 we conducted four harbor seal tagging trips in Cook Inlet during the months of October and May. In total, we captured and released 93 harbor seals, 77 of which were tagged with satellite transmitters. Each transmitter was glued to the hair on the back of the seal using durable epoxy. Fourteen of the seals were also equipped with specially developed transmitters that were attached to one of the rear flippers. Transmissions from the 91 tags resulted in 178,536 location estimates and 310,593 dive and haul-out behavior records. These data formed the basis for the development of novel analysis techniques. Johnson et al. (2008) described a novel continuous-time correlated random walk (CTCRW) method for predicting animal locations from satellite tags. Higgs and Ver Hoef (2011) described a new statistical method for analyzing dive behavior based on dive histogram recordings obtained from satellite tags.

The data files within this dataset represent the 'raw' data obtained from the Wildlife Computers data portal. Each deployment (unique tag id + animal id combination) is provided as a zipped archive. The root folder also includes additional documentation. The various files and detailed column descriptions are described in the 'Spreadsheet-File-Descriptions.pdf' which was downloaded from Wildlife Computers (https://wildlifecomputers.com/support/downloads/). The '00_cookinletpv_get_data.Rmd' file is an RMarkdown file that provides code and documentation of the data retrieval process. The corresponding '00_cookinlet_get_data.hml' file is autogenerated from the RMarkdown file.

AFSC/NMML: Platforms of Opportunity Program (POP): 1950 - present

The Platforms of Opportunity Program (POP) is an opportunistic marine mammal sighting program that dates back to the 1950s and includes over 108,000 sightings.  Sightings have been submitted by a number of sources including: NOAA vessels, USCG vessels, USFWS vessels, various research vessels, and the NMFS commercial fishery observer program.  While data for POP is collected on a not-to-interfere basis, the opportunistic sightings provided have greatly improved the understanding of marine mammal distribution.  In general, POP data has been used to document both historic and present occurrence and distribution of marine mammals, help identify potential cruise routes for systematic marine mammal surveys, and aid in examining relationships between marine mammals and fisheries.

Alaska Harbor Seal Haul-out Locations

Aerial surveys of coastal Alaska are the primary method for estimating abundance of harbor seals. A particular challenge associated with aerial surveys of harbor seals is maintaining consistent spatial representation of haul-out locations (waypoints). In some cases, seals aggregate into a single large grouping at a particular area. In other cases, seals aggregate into several smaller groups spread over a particular area. To establish geo-spatial consistency, the Alaska Fisheries Science Center (AFSC) maintains a list of haul-out locations that represent known harbor seal aggregations in Alaska.  Haul-out locations were identified through aerial survey efforts and historical knowledge. Locations are assigned a unique alphanumeric identifier, based on the survey unit they fall within, and the spatial data are provided in the geographic (epsg:4326) coordinate reference system. These haul-out locations are used to inform management decisions pertaining to coastal activities (presence/absence of seals in a particular area) and to facilitate AFSC field work that includes both aerial and vessel surveys. Haul-out locations are updated annually based on information obtained from aerial survey observations. This dataset contains Alaska harbor seal haul-out locations that are recorded primarily to support aerial survey efforts in August and (in some areas, June). Harbor seals are known to use various haul-out locations seasonally and, thus, this is likely not a complete collection of harbor seal haul-out locations. Some haul-outs that are close together may be combined and represented as one site or waypoint. Important haul-out locations have been identified in the "status" field of the attribute table and are labeled as "key haulout" if a particular location contains 50 or more harbors seals. A haul-out location containing less than 50 harbor seals is labeled "not key haulout". This number may change as more in depth analysis continues.

AFSC/RACE/SAP/Swiney: Primiparous and multiparous Tanner crab egg extrusion, embryo development and hatching

This study compares timing of egg extrusion, embryo development, timing and duration of eclosion, and incubation periods of Kodiak, Alaska primiparous and multiparous Tanner crabs (Chionoecetes bairdi) reared in identical conditions to determine if and how these variables differ between reproductive states.  Female reproductive state (primiparous or multiparous) and dates of egg extrusion were recorded, eggs were sampled monthly to determine egg stage and area, and larvae were collected daily during eclosion to determine timing and duration of eclosion.
