**[Abstract]{.smallcaps}.** On 8 December 2004, the *Selendang Ayu* went
aground on Unalaska Island and spilled approximately 321,000 gallons of
IFO 380 fuel oil and approximately 15,000 gallons of diesel fuel. About
70 miles of shoreline were within the area of principal oiling, defined
as shoreline response segments where some portion required cleanup
action. As a preliminary step in the natural resource damage assessment
(NRDA) process, NOAA conducted preassessment surveys from December 27,
2004 through February 1, 2005 and from June 2 through 23, 2005. In the
winter surveys, NOAA damage assessment teams examined the shoreline for
patterns of oil movement and deposition, but daytime high tides were too
high to comprehensively examine intertidal habitats for indications of
oil impacts on the biota in these habitats. During two extreme low-tide
series in June 2005, NOAA and scientists working for the responsible
party conducted preassessment surveys of biota in intertidal, subtidal,
and stream habitats in the spill area. In visual surveys of the
perennial biota (algae and invertebrates) in rocky intertidal habitats,
indications of possible adverse impacts of *Selendang Ayu* oil were
observed at Spray Cape, but there were no other visible loss of species
or reduced abundances of biota observed at other sites that could be
attributed to the oil in the time period of 8 December 2004 to 20 June
2005. Shoreline clean-up operations, such as burning of oiled debris,
use of heavy equipment, and removal of sand and other material from
sections of oiled beaches, very probably killed or removed some
beach-wrack biota and infauna to varying degrees. Between 20 and 23 June
2005, the teams observed beach cleaning operations that resulted in the
release of oil into surface waters; this release apparently caused
bleaching and necrosis of marine algae at HMP-11a. Warm conditions
increase both the mobility and toxicity of heavy fuel oil, and these
clean up-related oil releases and potential impacts resulting from those
releasesmay have continued into the summer months after the field study
data collection ended on 23 June 2005. In addition, the U.S. Coast Guard
documented more releases of oil from the wrecked *Selendang Ayu* in
October and December 2005, some of which stranded on the shoreline. The
preassessment-scale surveys were designed to detect gross, acute,
readily visible effects, such as acute mass mortality of biota,
occurring before 23 June 2005. However, the observations made, as
described herein, suggest that injury likely occurred to intertidal and
subtidal biota. Additionally, injury to a variety of marine resources
can be inferred from experience with similar-sized spills in similar
environments and from the scientific literature.

**[Introduction]{.smallcaps}**

Preassessment surveys of intertidal, subtidal, and anadromous stream
habitats, and associated fauna and flora were conducted in two time
periods. In December 2004-January 2005, NOAA staff conducted preliminary
field surveys of intertidal shores, subtidal habitats, and freshwater
streams on Unalaska Island, in the area affected by the *Selendang Ayu*
oil spill. These winter surveys mainly focused on documenting patterns
of habitat oiling. Short day lengths, high daytime tides, and adverse
weather conditions limited the observations that could be made of biota
in these habitats. In June 2005, NOAA teams returned to the spill area
during a series of extreme low tides to specifically conduct a second
set of preassessment surveys of the biota in intertidal, subtidal, and
anadromous stream habitats. Observations made during these surveys are
presented below.

**[Description of the *Selendang Ayu* Oil Spill]{.smallcaps}**

On 8 December 2004, the *Selendang Ayu* grounded and broke in half on
Spray Cape, Unalaska Island, 53^o^ 38' 04" N, 167^o^ 07' 30" W (Figure
1). An estimated 335,732 gallons of fuels, mostly Intermediate Fuel Oil
(IFO 380), were released following the grounding. Additional information
about the incident is available at the Unified Command Website for the
*Selendang Ayu* incident:

<http://www.dec.state.ak.us/spar/perp/response/sum_fy05/041207201/041207201_index.htm>.

The Unified Command for the *Selendang Ayu* oil spill divided the 469
miles of shoreline in the potentially spill-affected area into 806
segments (Figure 2). Of these, 123 segments (70 miles) received enough
oil somewhere in the segment to require oil clean-up treatment. The sum
total of the length of oiled shoreline within all these segments was
over 20 miles. One hundred and two of the oiled segments were actually
approved for clean-up operations. Primarily because of safety concerns
for the cleanup personnel, the remaining 21 segments were not treated.

Beach cleaning operations in the summer of 2005 remobilized unspecified
quantities of stranded oil back into surface waters. In October and
December 2005, storm waves moved the wrecked sections of the *Selendang
Ayu*, causing the release of unknown quantities of additional oil for
unknown periods of time. A civilian aircraft reported observing sheen
around the vessel on 21 October 2005. The Coast Guard conducted
occasional overflights following this report. On 24 October 2005, the
Coast Guard conducted two overflights and reported seeing sheen and
emulsified oil. This release was thought to have the potential to oil
SCAT segments SPR 8, 10, 11, 12 and SKS 1, 2, 3, 4, and 5. The Coast
Guard reported seeing a slow rainbow sheen burping up 350 yards from the
stern section the following day, and saw a dull sheen the next day. No
new oil was observed on the next four overflights conducted from 27
October through 26 November2005, but a thin sheen was observed on 1
December 2005 (information on reports of aerial observations came from a
summary compiled by J. Hampton, Coast Guard). Through October 25, 2005,
the Unified Command estimated that approximately 1,000 gallons of
emulsified oil was released from the *Selendang Ayu* as a result of the
storm waves
(<http://www.dec.state.ak.us/spar/perp/response/sum_fy05/041207201/sitreps/041207201_sr_105.pdf>),
but this estimate has not been updated and may have missed possible
releases occurring before and after October 24, 2005 on days without
overflights. There is also no known estimate of the amount of oil that
was reportedly released during the December storm.

**[Surveys of the Spill Area]{.smallcaps}**

**Winter Surveys: Observations of oil and biota from NOAA field surveys
conducted in December 2004 -- February 2005.**

*Objectives:* The main objectives of the winter surveys were to document
patterns of oiling in habitats and collect ephemeral data (including
samples of biota and oil taken from the shore).

*Methods:* NOAA pre-assessment teams conducted field surveys of the
spill area on-foot from 27 December 2004 through 1 February 2005, in
addition to observations made by Rapid Assessment Technique (RAT) and
Shoreline Cleanup Assessment Technique (SCAT) teams. NOAA personnel
participating in the pre-assessment field surveys were: Lisa DiPinto,
Nick Iadanza, John Cubit, Doug Helton, Ian Zelo, and Daniel Hahn, with
assistance from Danielle Savarese (Stratus Consulting). Janis Krukoff
and Laresa Syverson (both with Qawalangin Tribe) and USFWS personnel
also participated in these surveys. The USFWS vessel M/V *Tiglax* was
used as a working platform. Landing on beaches was accomplished using
skiffs. The selection of shoreline segments surveyed was determined by
the USFWS sampling plan used to survey the segments for bird carcasses.
This was a stratified-random design, with the strata being wave-exposed,
wave-protected, and accumulation beaches. Segments were randomly
selected within these strata. Segment identification codes were the same
as was designated for SCAT surveys and is shown in Figure 2.

*Observations and Discussion:* In these winter surveys, days were short
and daytime tides were high, so observations were limited to the highest
portions of the intertidal zone. However, SCAT surveys documented that
most of the oil on the shoreline e had been deposited at higher tide
elevations by storm waves in the supratidal zone and in the seaward edge
of the terrestrial vegetation. Most of the vegetation is Aleutian rye
grass. In the winter, the above-ground portions of this grass were dead,
straw-like, and appeared to have an affinity for the oil. In these high
locations the oil was beyond the reach of the normal tides. Some of the
oil was buried beneath gravel and cobble in storm berms. Evidence of
mobile oil in the form of patties (congealed oil mixed with straw from
Aleutian rye grass) was also observed. Many of the patties were about
the size, shape, and thickness of shoe soles, sporadically stranded on
the beaches. In these winter temperatures, any remobilized oil would not
be liquid and would not form spreading slicks.

With temperatures around freezing (\~32ºF, \~0ºC), most of the oil
stranded on the shore was the consistency of thick, cold, sticky peanut
butter. To illustrate the consistency of the *Selendang Ayu* oil in
winter, the oil could be picked up as a lump with a wooden tongue
depressor without losing its shape. When placed in seawater, it did not
give off sheen and barely floated (it floated with more than 95% of the
lump below the surface of the water). Nick Iadanza observed that the oil
appeared less viscous on days with temperatures in the forties (ºF)
(\~8ºC) and produced sheen when placed in seawater.

Most of the oil we observed was partially emulsified (i.e., had
incorporated water and become an oil-water mix). It was a medium brown
color instead of black. When pressed with a tongue depressor, the masses
of brown oil exuded droplets of water.

Numerous samples of potentially and visibly oiled sediments, the oil
itself, and various kinds of biota (mostly mussels) were taken. These
samples are being held in frozen storage and could be analyzed if the
Trustees determine the information is needed.

In examining the invertebrate fauna of high beaches at Spray Cape (SPR11
and SPR13) on 7 January 2005, Dan Hahn reported amphipods and isopods
coated with oil. These oil-coated crustaceans were both live and dead.
Some of these appeared to have crawled upwards through the overlying
oil. Ty Wyatt (USFWS) made similar observations, including
photo-documentation (Wyatt, pers. comm.).

Additional observations of oil movement and deposition were made during
the June 2005 surveys described below. Numerous photos illustrating the
oiled shorelines and history of the *Selendang Ayu* oil spill are shown
on the Incident Command website:
<http://www.dec.state.ak.us/spar/perp/response/sum_fy05/041207201/041207201_ph_index.htm>

**June Surveys: Observations of oil and biota from NOAA field surveys
conducted in June 2005**

*Objectives:* The objectives for the June 2005 surveys were the
following:

-   Identify resources at risk; that is, identify fresh, brackish, and
    marine water biota and habitat in the spill area that could have
    been injured as a result of the oil spill, including clean-up
    activities.

-   Document degree of exposure of natural resources to *Selendang Ayu*
    oil. (This objective incorporated SCAT data already collected and
    documented presence of oil in the environment and in/on biota.)

-   Document indications of possible resource injury caused by the
    *Selendang Ayu* oil spill and clean-up actions.

-   Collect ephemeral data (data that would be lost if not recorded by
    these surveys at this time) regarding potential injury to trust
    resources.

-   Collect any additional information necessary for designing or
    implementing future NRDA and restoration studies.

**Surveys of Intertidal Habitats in June 2005**

*Methods:* The NOAA and responsible party preassessment team conducted
two sets of surveys of intertidal habitats in June 2005, coinciding with
the minus low tide series of 2-9 June and 19-23 June. The extreme low
tides during these two periods facilitated our access to the lowest
intertidal levels of the shores in the spill area.

The primary scientific personnel conducting the intertidal surveys for
NOAA are all marine biologists with years of experience surveying
intertidal biota in Alaska and/or the Pacific Northwest.

1.  John Cubit (Lead scientist), marine ecologist, NOAA Damage
    Assessment Center: all June 2005 surveys (2-9 June and 19-23 June)

2.  Allan Fukuyama, marine ecologist, University of Washington: first
    June surveys (2-9 June 2005)

3.  Sandra Lindstrom, marine phycologist, University of British
    Columbia: first June surveys (2-9 June 2005)

4.  Carolyn Kurle, marine ecologist specializing in Aleutian Intertidal
    biota, University of California, Santa Cruz: second June surveys
    (19-23 June 2005)

Ian Zelo (NOAA Hazmat) was data manager and participated in various
field surveys. Nick Iadanza (NOAA DAC) and John Hudson (NMFS Auke Bay
Laboratory) also participated in these intertidal field studies, but
focused primarily on surveys of anadromous fish streams (see stream
section below and their separate reports in the appendices). Jordan
Stout (USFWS) conducted the photo-documentation for Cubit's surveys in
the first tide series. Christian Marcotte provided field support for
Carolyn Kurle's surveys. Amy Merten (NOAA Hazmat) also contributed field
support. Representatives of the responsible party who participated in
the surveys were Gary Mauseth, Bruce Kvan, Greg Challenger (all of
Polaris Applied Sciences), and Jon Houghton (Pentec Environmental)[^1].

The work platform for these studies was the F/V *Ocean Olympic*, a
155-foot commercial crab fishing vessel whose use was arranged and paid
for by the Responsible Party. Shores were accessed by skiffs with
experienced skiff operators. In the fjord-like coastline of the spill
area, the captain of the F/V *Ocean Olympic* was able to position the
vessel near all the study areas for rapid access by skiff. This
arrangement allowed the field team to visit any shore at any time of
day, weather permitting, and then process data aboard the vessel. High
surf prevented landing on some shores on some days, but visits to all
shores of interest (as described below) were achieved by adjusting
schedules around wave conditions. Thus the choice and number of
shoreline locations visited was not restricted by accessibility.

Survey sites were chosen to maximize the following:

1.  Geographic variation in the spatial patterns and degrees of oil
    exposure (e.g., amount of exposed surface covered with oil, amount
    of oil buried in beach, amount of oil deposited on high shore,
    extent of exposure to oil remobilized by beach cleaning operations,
    etc.). The northern extreme of the geographic range was Volcano Bay;
    the southern extreme was Chernofski Harbor (see map, Figure 1). The
    sites at the outer range of the surveys were only exposed to
    sporadic tar patties, as far as is known.

2.  Ranges of substrate and shore types (e.g., mud, sand, gravel,
    cobble, boulder, solid bed rock, vertical shore, horizontal
    platforms, and combinations thereof).

3.  Ranges of wave exposure (ranging from very high energy,
    wave-exposed, shores to very wave-protected, lake-like, inner
    inlets, with many intermediate shores within this gradient). The
    highly indented shoreline of the spill area had many bays and
    inlets, creating a high diversity of wave-exposure regimes.

4.  Variations in types and diversities of intertidal biological
    communities (e.g., tidal marsh, algal dominated, invertebrate
    dominated, high diversity, low diversity, cryptic \[under rock\],
    exposed).

5.  Per the methods described in the following, we also chose sites in
    the field to make matched comparisons of recently oiled and not
    oiled ("reference") sites. This was done to scientifically
    investigate and test hypotheses regarding causality of effects
    observed during the field surveys.

> Shoreline location segments (e.g., "SKN14") were identified using the
> alphanumeric system instituted by the *Selendang Ayu* Unified Command
> (see map in Figure 1).

*Field Methods:* Because the location of the *Selendang Ayu* oil spill
was remote and difficult to access, there was little preliminary
information regarding possible impacts on which to base our survey
designs. Therefore, we used an adaptive survey strategy in which one
day's observations were used to determine the next day's operations.
This strategy included field designation of gradients of oil exposure
and designation of unoiled reference sites to test hypotheses that oil
exposure caused any apparent adverse effects observed in the field.

In the field, the adaptive survey process was designed to function as
follows. If apparent injury to biota was observed in the field, the
first step was to determine if this injury was consistent with exposure
to oil, as opposed to other factors, such as predation or effects of low
tide exposure. Next, the shoreline location having apparently injured
biota was compared to a "reference" location, which was the nearest
location that had the same shoreline aspect (exposure to wave action,
elevation, topography, etc.,) and habitat type, but with little or no
exposure to oil. If similar injury also occurred in the reference
location, the hypothesis that the injury was likely a result of exposure
to oil discharged from the *Selendang Ayu* could be rejected.

As described below, at each site close-up examinations of the biota and
substrata were made at all accessible shore levels. This included wading
into shallow subtidal areas where shoreline slope and wave conditions
permitted. The field surveys were conducted around the daytime low
tides. The surveys started at upper tidal levels of the shore during the
falling tide and proceeded to the lowest intertidal levels as the tide
receded. Most intertidal surveys were conducted on foot after landing
from skiffs. Vertical rock faces emerging from deeper water were
surveyed from skiffs positioned next to the rock face. Observations of
shallow subtidal biota were accomplished by wading into these habitats
or floating over them in the skiffs. Deeper subtidal biota were surveyed
by divers and video cameras, as described in the subtidal section.

1.  Observations were made directly in the habitat surveyed, not from a
    distance. Biota were examined within arm's length.

2.  In the field, biota were examined, the condition, degree and
    distribution of oiling, and any indications of impacts of oil on the
    biota were documented. These observations were made by field
    biologists familiar with the taxonomy, appearance, and ecology of
    these species, including the effects of natural factors on these
    biota.

3.  Biota were specifically inspected for visible oiling, abnormal
    coloration, necrosis, empty shells, abnormal behavior, mortality,
    and any other indications of possible oil exposure and oil effects.
    In particular, biota more than seven months old, i.e. preceding the
    *Selendang Ayu* grounding and oil spill, were carefully examined.

4.  Fronds of large algae were lifted as necessary to view biota and
    oil, if any, beneath the fronds.

5.  On beaches and boulder shores, boulders and cobble were lifted and
    gravel excavated, to examine cryptic biota.

6.  Documentation of the observations made during the survey was by
    field notes and digital photographs, primarily.

7.  Photographs were taken as close as necessary to document the species
    present, the condition of the biota, and patterns of oiling, if oil
    was present. Most documentation photos covered an area of about
    0.25-1 square meter. Photographs of larger areas were used to
    document habitat-scale features.

8.  Locations of photographs were recorded using the combined software
    set of Ozi Explorer (www.oziexplorer.com) and Ozi Photo Tool
    (oziphototool.alistairdickie.com). This software combination linked
    the GPS tracks to the digital photographs. GPS waypoints were used
    to link observations made in field notes to specific shore locations
    .

9\. Voucher specimens were taken as necessary.

*Observations and Discussion:* Portions of 55 shoreline segments
(Table 1) were surveyed according to the procedures described above.
Photo-documentation was extensive, totaling approximately 13GB of
digital photos.

[Rocky shore biota]{.underline} On shores with substrata of physically
stable bedrock and boulders, an established biota of perennial marine
algae and marine invertebrates was found (Table 2). Shores along the
northeastern portion of Spray Cape (SPR11-SPR14) are near the wreck of
the *Selendang Ayu*. In these segments, splatters of oil remained high
on the shore. Here Lindstrom reported that the kelps (*Laminaria
longipes* and other species) were reduced to stipes\--the main portions
of the blades were absent. Also, grazer populations appeared to be
reduced. Bedrock at lower tidal elevations and fronds of the perennial
algae *Fucus, Mastocarpus, Petrocelis*, and *Laminaria* in the
mid-intertidal zone were overgrown by ephemeral green algae (e.g.,
*Acrosiphonia Ulothrix,* and *Urospora*).

On other shores, both oiled and unoiled, the perennial species were of a
size and condition that indicated they had been present before the
*Selendang Ayu* oil spill---i.e., they had settled and grown before 8
December 2004. In close and careful examination of the perennial biota
there were no indications of visible acute mortality or other adverse
effects on these perennial biota, except for Spray Cape and HMP-11a
which was exposed to remobilized oil from beach clean-up operations in
June, 2005.

Rocky shores were examined for the "green shore phenomena" caused by
mortality of herbivores, which has been observed in other spills and in
controlled field experiments removing herbivores. At all sites except
Spray Cape, no clear indications of blooms of ephemeral algae that
exceeded the normal spring blooms of algae found on these kinds of
shores in the spring were found. Patterns of grazing marks, grazing
patches, and herbivore distribution in these habitats indicated that
*Littorina* *sitkana* and limpets (Lottiidae) were consuming the
bloom-forming algae, forming cleared areas in the stands of the
ephemeral algae. However, Lindstrom believes that the extent of growth
of ephemeral green algae (*Acrosiphonia, Urospora, and Ulothrix)* at
Spray Cape exceeded normal seasonal growth, especially where these green
algae were growing as epiphytes on perennial algae in the mid-intertidal
zone and on bedrock at lower tidal elevations. Lindstrom attributed the
extent of this bloom to a general lack of grazers at these tidal
elevations at this site. The cause for the observed lack of grazers
cannot be attributed to oil exposure with the available information.[^2]

[Beaches of cobble, gravel, sand]{.underline}. An abundant and diverse
assemblage of cryptic beach invertebrates was observed beneath cobble,
drift seaweeds and other beach wrack. These included talitrid amphipods
("beach hoppers"), centipedes, arachnids, and kelp flies. The talitrids
were at densities of 1 to 10 per 100 cm^2^. In some cases, beach biota
were within 10 cm of mats of buried oil, but no oil was found on the
biota. In addition, on 19 June 2005, oiled wrack (accumulations of dead
plant material) harboring amphipods living in direct contact with oil
was observed on the beach at SKN-6. Although the amphipods did not
appear oiled or to be experiencing acute effects from the oil, amphipods
living in such close proximity to oil could serve as potential vectors
of oil to higher trophic levels. Foxes were seen overturning rocks and
wrack on beaches, apparently feeding on the beach invertebrates found
there.

In the course of the surveys, large amounts of beach material were
observed being removed from heavily oiled sections of beaches for
disposal at waste sites. This material probably contained beach biota.
For example, the excavating machinery at SKN-11 was removing the oiled
cobble and gravel, placing it in "Super Sacks" for transport out of the
area. Any biota in the beach material would have also been removed.
Excavating machinery could have also crushed beach biota. In addition,
oily debris was moved into piles and burned on some beaches which would
have killed beach-wrack fauna and infauna in the vicinity of the fires.
Many of the areas where burning of debris was conducted were in high
wave energy areas with cobble and pebble sediments that are unstable and
dynamic and may have less interstitial biota than areas with lower wave
energy and finer sediments.

[Observations of remobilized oil and apparent impacts on rocky shore
substrata and biota:]{.underline}

Beginning on 20 June 2005, new deposits of sticky brown oil were
observed in some of the areas surveyed. The oil appeared to have been
released from beach cleaning operations in adjacent shoreline segments.
In some cases, excavations had been made into layers of oil buried in
gravel-cobble beaches, and high tides had lifted oil out of the
excavations. Segment HMP-12 was a pilot project for "berm relocation"
and "surf-washing," in which oiled beach material from a section of high
beach was bulldozed into a lower intertidal area where wave action could
remove the oil. Berm relocation was also used at segments SKN-05,
SKN-06, and SKS-04. Table 3 summarizes currently available information
from various sources on the response actions taken at each SCAT segment.
Because there has not yet been a compiled and verified accounting of the
actions taken at all segments, the information in Table 3 should be
regarded as giving an approximate sense of what occurred, except
descriptions of clean up at segments directly observed by the survey
teams for this report.

On 20 June 2005, at the rocky point at HMP-11a, rainbow sheens of oil
were observed on tide pools, including oil streaming from floating
droplets of black oil. In the mid-tide zone sticky, brown oil was
deposited on the rock surface and on attached biota. The fronds of
*Palmaria* and holdfasts of *Alaria* in this zone were oiled. In the
high intertidal zone and splash-zone, freshly deposited, shiny, sticky
oil was also present on rock substrata and on the fronds of the red alga
*Porphyra*. Fresh oil was also present on wrack at the higher high water
level. The oil appeared to be remobilized from beach cleaning operations
to the west of HMP-11a, in segments HMP-11b and HMP-12. Dry tilling to
expose buried oil at HMP-12 for removal by natural factors is shown in
the photo at the end of this document. (A list of all photos available
on the Unified Command website can be found at:

<http://www.dec.state.ak.us/spar/perp/response/sum_fy05/041207201/041207201_ph_index.htm>).

Freshly remobilized oil was observed in the north part of Skan Bay
during the calm weather of 22 June 2005. There were oil sheens on the
water surface of the cove at SKN-10 and SKN-11. Oil sheens here ranged
from silver through rainbow in color and some brown-black patches of oil
were also observed on the water surface of the cove at these SCAT
segments. Rainbow sheen covered about 50% of the water surface in the
landward part of the cove---an area of several hundred square meters,
occupying the landward end of the cove, and extending about 100 m from
the beach at the head of the cove. Bands of floating black oil about 1
cm thick were accumulated against the floating fronds of the kelp
*Alaria*---the fronds were acting like low-profile oil booms. The oiled
*Alaria* bed was about 50 m by 100 m. An on-scene biological advisor for
the clean-up said that high tides had washed oil from the excavations
made to remove buried oil from the beach. Oil was buried in the berm of
the beach at SKN-11 and the beach wrack was more than 80% oiled. A
backhoe/front loader and two excavators were digging oiled sediment out
of the beach, and the highest concentrations of oil in the water and on
the shore were at the beach cleaning operations, diminishing with
distance from the excavation sites. There were no booms in place to
retain the oil when we made these observations, but (pom-pom) booms were
placed along the beach later in the day. The rocky shoreline of SKN-10
projected seawards from the oiled beach at SKN-11, forming the south
side of the oiled cove. Freshly deposited, sticky, oil was most evident
in the upper intertidal zone of SKN-10, forming a band of oil- a
"bath-tub ring" effect- on the rocks. The band was about 20 cm -- 45 cm
wide (vertical measure) and the coating of oil ranged in thickness from
stain to about 5 mm. Shiny black oil was observed on barnacles, mussels,
limpets (*Lottia* spp.), *Littorina* *sitkana*, and *Fucus*. At the
beach end of the shore (nearest the remobilized oil), 100% of the
*Porphyra* were coated with oil.

Upon returning to HMP-11a on 23 June 2005, it appeared that more than
90% of the red alga *Palmaria* had oil on their fronds. The typical
color of this alga is dark purple-red to wine red, however, \>90% of the
oiled fronds (by surface area) were bleached to a light yellow-green
color, some almost white, and the tips of the fronds were ragged. Less
than 40% of the *Alaria* were oiled at the base. More than 80% of the
normally bright green *Acrosiphonia* were also discolored (bleached tips
and tan-brown coloration over \>80% of the frond surface), although no
oil was seen on the fronds of this alga. Submerged *Palmaria* at HMP-11a
were also oiled and bleached. As documented in the field photos, all of
these algae were common within their zones.

To evaluate effects of remobilized oil on the intertidal algae, HMP-13
was chosen as a "reference" site for HMP-11a. HMP-13 was the next rocky
point to the west of HMP-11a, about 1 mile away. It faced the same
direction and had similar wave exposure, but no remobilized oil was
found there on 23 June 2005. HMP-13 appeared to be up-current or up-wind
from the HMP-11a and the remobilized oil. Clean-up operations in the
Hump Back Bay area were underway before HMP-13 was surveyed, so it is
possible that the algae at the HMP-13 "reference" site had been oiled
prior to the observations. Oil was not observed on the fronds of
*Palmaria* at HMP-13, but these algae showed the bleached discoloration
similar to, but less than, the oiled fronds at HMP-11a. However, the
*Palmaria* fronds at the HMP-13 reference site were not ragged like
those at the HMP-11a oiled site. The *Acrosiphonia* was also much less
discolored at HMP-13. Bleached fronds of *Alaria* were similar in
appearance at sites with recent exposure to oil and at sites without
recent exposure to oil.

In the lower intertidal zone, three species of large brown algae appear
to have been affected by the oil. *Agarum (or* possibly
*Thalassiophyllum)* and *Alaria* were discolored, an effect that
diminished with distance from the oiled beach. *Laminaria* formed a
nearly continuous bed along the low tide shoreline. The *Laminaria* were
bleached and ragged at the end of the shoreline near the beach cleaning
operations; this phenomenon decreased to near zero with distance from
the beach cleaning operations. *Agarum*, *Alaria,* and *Laminaria* are
normally dark brown color. The bleached fronds were pale brown to pale
greenish brown. Although *Palmaria* had some bleaching, and
*Acrosiphonia* some discoloration, at the HMP-13 reference site, these
effects were greater at HMP-11a. Because fronds of *Palmaria* spp. and
*Acrosiphonia* spp. can bleach or change color and erode naturally in
the summer when they release reproductive cells (S. Lindstrom, pers.
comm.), it cannot be concluded that the all of observed color changes,
bleaching, and erosion in these two algal species occurred solely as a
result of exposure to *Selendang Ayu* oil. However, it can be concluded
that most of the adverse effects observed on these and other algal
species at HMP-11a was probably due to oil exposure.

[Summary of June Intertidal Surveys]{.underline} In the June 2005 survey
of intertidal beaches, the subsurface beach fauna were observed living
in close association with deposits of oil without any visible oiling on
the animals or causing any readily observable effects. However, beach
cleaning operations were seen removing large amounts of beach sediment
and wrack at some locations, probably removing beach fauna at the same
time. A total of 666,592 bags of oily waste material were removed from
the shorelines in the spill area as of June 19, 2006. Use of excavators,
front-loaders, and other heavy equipment on beaches probably crushed
beach-wrack biota and infauna. Burning of oily debris on beaches
probably caused additional mortality of the fauna located there.

Observations at Spray Cape (SPR11-SPR13) indicated that some biota had
experienced recent adverse impacts by oil or some other factor. Kelps
were reduced to stipes. Herbivore abundance appeared to be reduced.
Epiphytic overgrowth of various perennial algae by ephemeral green algae
at this site, but not others, indicates a reduction in herbivory. The
extent of growth of these ephemeral green algae on low intertidal
bedrock also indicated reduced herbivory. Although the rotting deposit
of beans ("Bean Beach") was primarily to the southwest of SPR11-SPR13,
some rotting beans were also present in segments SPR11-SPR13 and
nutrients or other substances released by the beans may have caused, or
contributed to, the adverse effects observed for segments SPR11-SPR13.

In the pre-assessment surveys between 27 December 2004 and 20 June 2005,
no evidence was found of acute mortality of perennial marine biota
(algae and invertebrates) on rocky shore segments other than Spray Cape.
On these rocky shores, the major groups of long-lived marine algae and
invertebrates of the intertidal and shallow subtidal rocky habitats
appeared to be largely intact. No observable changes in abundances or
conditions of intertidal biota correlated with degrees of oiling were
found prior to 20 June 2005. For example, the large barnacle
*Semibalanus cariosus* has a life span of more than a year and has a
strong test (shell) that can persist for many months after the animal
dies. Therefore, it was a useful indicator of mortality caused by the
spilled oil. If the oil had killed this barnacle, a higher relative
proportion of empty tests at sites more exposed to oil should have been
found. Empty tests of this barnacle were found at all sites, regardless
of oiling. However, at all sites more than 50% of the barnacles were
alive, and no obvious correlation was found between number of empty
tests and degree of oiling as judged by the amount of oil deposited on
nearby beaches or reported to have been in the area in SCAT surveys.
These observations were consistent over a wide range of sites and for
many different types of long-lived biota and suggest that the mortality
that was observed is likely due to natural factors. Prior to 20 June
2005, the *Selendang Ayu* oil spill probably did not cause acute
mortality for most of the perennial intertidal biota in the spill area
except at Spray Cape (but see footnote 2).

However, starting 20 June 2005 indications of adverse impacts were found
on various species of marine algae that was likely caused by oil that
was recently remobilized from beach cleaning operations during the
warming weather of the Aleutian spring and early summer. To separate
effects of oil exposure from non-oil factors, such as exposure during
the spring low tides, the conditions of the alga fronds were compared as
follows: (1) along gradients of exposure to remobilized oil and (2)
between sites that differed in the amount of visible remobilized oil.
These observations indicated exposure to remobilized oil was a probable
cause of adverse impacts on the algae *Palmaria*, *Laminaria*,
*Acrosiphonia*, and *Agarum*, all of which showed signs of bleaching and
tissue erosion in the areas exposed to oil released from buried deposits
of oil by beach cleaning operations. As noted earlier, there was some
bleaching of Palmaria and discoloration of Acrosiphonia at the reference
site (HMP-13), but these effects were much greater at HMP-11a,
suggesting that oil exposure was the predominant cause of these adverse
effects.

The surveys ended on 23 June 2005, and no further observations were made
on the potential long-term impacts of the *Selendang Ayu* oil released
into the spill area by beach cleaning operations in the summer of 2005.
However, mechanical excavation and/or tilling occurred at ten or more
segments, in addition to that observed at HMP-11b and HMP-12 during the
June Survey, and it is likely that some oil was remobilized by the clean
up operations at some of these other segments. In addition to *Selendang
Ayu* oil released from shoreline deposits, the U.S. Coast Guard also
reported releases of oil in October and December 2005 when storms
shifted the hull of the *Selendang Ayu* (Table 4). A U.S. Coast Guard
overflight on 1 December, 2005 reported sheening originating from the
stern section of the vessel. Dan Magone (5 Dec 2005, in litt.) also
observed oil slicks on 1 December 2005 in Skan Bay, but the source was
unknown. It is also worth noting that many segments where oil had not
been observed in winter clean up operations were visibly oiled when the
clean up resumed in spring 2005. Many of these segments were observed by
helicopter and fixed-wing aircraft in the winter SCAT surveys, however,
and oiling at some locations may have been missed with this method. A
summary of reports of remobilized oil is given in Table 4.

Oil persisted in 26 segments at levels above that determined as "end
point" by the Unified Command after clean up operations ended in 2005
(Table 4). When the response officially ended on 23 June 2006, six
segments had still not achieved end point status, with residual oil left
to be removed by natural processes. This lingering oil has the potential
to cause some continuing level of injury until natural recovery occurs.

**Surveys of Subtidal Habitats in June 2005**

*Methods:* Subtidal habitats were briefly surveyed by divers using the
same basic methods of close-up observations employed in the intertidal
surveys and by tethered video. These subtidal surveys were conducted on
the same cruise as the intertidal surveys. The divers examined the
subtidal habitats for presence of oil and indications of injury that may
have resulted from exposure to oil. In addition a tethered video camera
was deployed from the *Ocean Olympic* to look for presence of oil and
potential injury. The diver representing NOAA was Alan Fukuyama, who
also participated in the intertidal surveys. Gary Mauseth or Greg
Challenger represented the responsible party on the dives, with Bruce
Kvan as back-up.

*Observations and Discussion:* The diving team did four dives: one at
Alimuda Bay, two at Humpback Bay, and one at Spray Cape near the
*Selendang Ayu* wreck. The latter three were in the main spill area;
Alimuda Bay received less oil. Cold water conditions limited the
duration of the dives to about 30-35 minutes. Divers did not go below 61
feet. Most of the habitats surveyed were in depths less than 50 feet.

The divers found scattered "tar spots" in 15-20 feet of water in one of
the Humpback Bay locations, which was adjacent to HMP-12.[^3] This was
just offshore of the location of a test berm relocation exercise. Videos
from the tethered camera and the divers found no definite indications of
adverse impacts of oil in this area. No oil was observed at the other
three dive locations.

**Surveys of Anadromous Fish and Streams in June 2005**

*Methods:* In June 2005, Nick Iadanza and John Hudson surveyed ten
anadromous fish stream systems for presence of oil and fish and other
indications of potential exposure of the fish to oil (Table 5). These
ten streams were chosen because:

1.  The streams were in the set of streams monitored for dissolved PAHs
    (polycyclic aromatic hydrocarbons) by the NOAA Auke Bay Laboratory
    team. This set included both oiled and unoiled streams. The Auke Bay
    study results are reported separately in the report in the
    Administrative Record, entitled "***Selendang Ayu* oil risk to early
    life stage salmon" (**Mark G. Carls, John Hudson and Stanley D.
    Rice, NOAA/NMFS/Auke Bay Laboratory, 11305 Glacier Hwy. Juneau, AK
    99801)

2.  SCAT surveys had reported oil up into the stream system, not just at
    the mouth of the stream.

The surveyors walked the streams, making close visual observations for
the presence of oil and fish. In some cases, they examined submerged
rock surfaces for biota and collected fish in sieves for closer
examination.

*Observations and Discussion:* In the June 2005 surveys, oil sheen was
found on upstream (freshwater) portions of the stream system at SKN 14,
including in rearing habitat for coho salmon and Dolly Varden char. Of
the anadromous streams visited, SKN-14 contained the highest quantity
and quality of coho salmon rearing habitat. Because oil was deposited
along the banks of this system for up to 1.7 km upstream of the
mouth,[^4] large numbers of juvenile coho, and their invertebrate prey,
were potentially exposed to oil. Sculpin eggs were also present.

Tar spots and tar balls were also found in the stream bed at MKS-5. This
stream contained juvenile coho salmon (young of the year through 2-year
old stages) and Dolly Varden Char.

The stream at HMP-12 was examined on 20 June 2005, when clean-up crews
were working on a deposit of oil from the adjacent beach at HMP-11b. The
high intertidal area at HMP-12 had been tilled to expose the buried oil
to removal by natural factors after bulk removal of oil deposits by
hand, which includes remobilization by wave action, according to
information posted on the Unified Command website
(<http://www.dec.state.ak.us/spar/perp/response/sum_fy05/041207201/041207201_index.htm>).
Oil-stained rocks and tar balls mixed with sediment were found along
portions of the stream bank, where Iadanza reported 100% cover of oil on
stream banks on the lower 100m of stream during a 19 January 2005 site
visit. In the second trip to HMP-12 (23 June 2005), a 60% cover of oil
was observed deposited on a gravel berm adjacent to the salmonid stream
at a distance of 80 - 100m from the stream mouth. On both visits to
HMP-12 (20 and 23 June 2005), oil sheen was seen in the intertidal areas
of the beach on both sides of the stream mouth, below the location where
beach materials had been redistributed. There was oiled wrack near the
stream mouth and oil-stained rocks in the stream mouth.

Most of the visible deposits of oil in the winter surveys had been
removed from the upstream (freshwater) portions of the remaining
previously oiled streams that they examined by the time of the June,
2005 surveys. However, some oil still remained on the marine beaches at
the mouths of some of these streams. At HMP 11, oil sheen was observed
draining from marine beach cleaning operations on both sides of the
stream. Oil and oil sheen was also observed on the marine beach at PTN
3. Oil was also found on the marine beaches and rocks of shoreline
segments SKN 14, SPR 3, PTN 3, HMP 11, and HMP 12, at, or adjacent to
the mouths of anadromous fish streams.

**Observations of possible effects of oil on fish in anadromous
streams** Coho salmon, Dolly Varden char, and sculpin were observed in
streams that had been oiled to some degree by *Selendang Ayu* oil. These
observations are not sufficient in themselves to detect adverse impacts,
if any, of the oil but they strongly suggest exposure of these fish to
oil.

However, mortality of the smelt eulachon (*Thaleicthys pacificus*) was
observed in Humpback Bay (HMP 9 and HMP 12) on 20 June 2005 in areas
where oil was being remobilized by beach-cleaning operations. On this
date, fresh, sticky oil recently deposited on the shore at these sites
or immediately adjacent to these sites was observed. At the high tide
line of the beach at the mouth of the stream at HMP-12, 332 dead adult
eulachon were found. Examination of a sub-sample of these fish indicated
that the females were full of eggs and the males had testes that were
intact; the fish had not yet spawned. The condition of the fish
indicated they had died within the previous 24 hours. Schools of live
eulachon were observed in the stream HMP-12. Approximately 200 dead
eulachon were observed under similar circumstances at the mouth of the
stream at HMP-9. These eulachon were also in pre-spawning condition
(full of eggs and testes intact).

Dead eulachon were observed being eaten by kittiwakes, a juvenile bald
eagle, and a fox during the survey at this site. The eulachon could
therefore have served as a mechanism to get oil into the food web. It is
not certain that the eulachon were killed by oil from the *Selendang
Ayu*, in part because no "control" sites or other reference information
were available to determine if such mortality occurs naturally. However
oil was present in the environment when and where the fish died, and the
gravid condition of the dead fish indicated mortality was not a result
of spawning, so mortality from exposure to oil is one possible cause of
death (among other possibilities).

The presence of oil in June 2005 on the marine beaches at the mouths of
five streams indicates the potential for storms waves and tides to
subsequently move the oil and recontaminate the lower reaches of these
streams after the June surveys were finished. Oil released from beach
cleaning operations in summer/fall 2005 and discharged from the
*Selendang Ayu* starting in the fall of 2005 could have also
recontaminated the streams after our June 2005 surveys.

The stream surveys conducted in late June 2005 are not sufficient in
themselves to determine if salmonids in the *Selendang Ayu* spill area
were injured, or not, by the oil that washed into the freshwater streams
in early December 2004. The necessary comparative data from previous
years combined with other sites to determine if the coho salmon and
Dolly Varden char observed in these streams were at reduced or
unimpacted densities are not available. Pink salmon juveniles probably
would have migrated to sea before June 2005, especially because the
winter of 2004-2005 was reported as unusually warm, which would have
accelerated time to hatching and alevin development, so there may have
been some mortality to juvenile pink salmon that would not be observed
during the June 2005 survey. It is possible that fish in the oiled
streams could have suffered sub-lethal adverse effects, such as impaired
development, growth, reproduction, long-term survival, or site-return
from exposure to non-lethal concentrations of oil.

**Determination**

The observations made during the winter and June surveys, together with
information coming from the Unified Command, are sufficient to make the
determination that some level of injury did occur to at least some of
the resources and habitats examined in the intertidal, subtidal and
anadromous stream surveys as a result of the *Selendang Ayu* oil spill,
including from the clean-up operations that took place following the
spill. The most evident injuries are those caused by the response -
removal of oiled sediments or burning of wrack from the shoreline with
its associated fauna - and those to habitats, such as the oiled
vegetation and heavily oiled shoreline of some salmonid streams. Some of
the impacts to algal species in and around those being actively cleaned
during the June 2005 survey may have resulted from remobilized oil.
These impacts could have continued throughout the clean-up operations in
the rest of the summer. At Spray Cape, there appears to have been a lack
of herbivores, possibly a result of the spill, and resulting bloom of
ephemeral green algae. There were also observations of dead eulachon,
which could potentially be a result of exposure to oil from the
*Selendang Ayu*.

Much of the most apparent and likely injury appears to be the result of
response actions taken during warmer weather at some of the most heavily
oiled areas. Biota in these areas and those nearby were exposed to
remobilized oil, and some injury is likely to have resulted from that
exposure- such as the apparent oil-related injuries to some algal
species. While not observable in our surveys, there is also likely to
have been sub-lethal effects to some biota within the areas most
affected by the spill. However, the magnitude of likely injury resulting
from the *Selendang Ayu* incident is relatively moderate, except perhaps
at the most heavily oiled areas and those in the vicinity of oil
remobilized during the cleanup operations in the spring and summer of
2005. The total length of shoreline where oil was observed to be present
is approximately twenty miles, so some degree of injury to these
habitats and biota likely occurred over a large area. The observations
made during the winter and June surveys, together with information
obtained from the response efforts, and what can be reasonably inferred
from experience with the effects of similarly-sized spills in similar
environments and the scientific literature indicate that an as yet
undetermined amount of restoration will be needed to address the injury
to natural resources and services in the intertidal, subtidal, and
anadromous stream habitats.

**Table 4.** Summary of observations pertinent to oil remobilization
made in the Selendang Ayu spill area from June 2005 onwards.

  ------------------- ---------------------------------------------------
  **DATES**           **OBSERVATIONS**

  20-23 June 2005:    NOAA survey teams documented remobilized oil from
                      beach cleaning operations in Skan Bay (SKN10-11)
                      and probably from beach cleaning operations in Hump
                      Back Bay (\~HMP10-12).

  August-September    Scott Arnold, Alaska Department of Health and
  2005                Social Services, reported elevated levels of total
                      PAHs in blue mussels from various locations in Skan
                      Bay, but not in other nearby bays

  \~September 2005:   Mark Carls reported increase of oil in PEMD
                      samplers at Skan Bay (SKN-14).

  21 October 2005     Unnamed observer in civilian aircraft reported what
                      appeared to be a sheen around thevessel. Coast
                      Guard reported oil from Selendang in water and
                      onshore around wreck (Spray Cape) and Skan Bay.

  24 October 2005     Coast Guard reported seeing sheen and emulsified
                      oil coming from the stern of the *Selendang Ayu*.

  25 October 2005     Coast Guard observed a rainbow sheen burping up
                      from around 350 yards from the vessel.

  1 December 2005:    Coast Guard/ADEC reported sheening from the vessel
                      (POLREP 104).

  1 December 2005     Dan Magone reported oil on about 200 feet of
                      shoreline near the Selendang; "grass has
                      distinctive droopy look...."

  3 December 2005     Dan Magone reported "ribbon of oil sheen" in inner
                      bay of "Lower Skan Bay".
