TO: Cook Inlet Stakeholder
FROM: Monty Worthington [email protected]
SUBJECT: ORPC Cook Inlet Tidal Energy Project Status Report No. 1 FERC Permit No. P-12679
Study Activities completed May and June 2009
Pre-Deployment Beluga Observations
LGL Alaska Research Associates, Inc (LGL) have been hired to monitor beluga whale presence, relative abundance, and behavior off of the north side of Fire Island, Upper Cook Inlet, Alaska. During May and early June, permits were obtained from Cook Inlet Region Inc. (CIRI) and the United States Coast Guard (USCG) to allow for access to private lands and permission to utilize the Race Point Lighthouse Reservation lands for the observation site. After establishing a suitable observation site, LGL guided National Marine Fisheries Service (NMFS) staff on a site visit on June 15; NMFS agreed the site would be suitable for the study observations.
The beluga observations were initiated June 17, 2009. Monitoring was conducted on nine days during June 2009 from the observation site near Race Point, Fire Island. Of these nine days, belugas were sighted on five days from the observation site. Of the five days belugas were sighted throughout the month of June, none of the sightings were within the tidal project’s Deployment Area. A chartered small fixed-wing aircraft is being used to travel to Fire Island and supplemental observations are made during each trip; no belugas were sighted during any of the 18 flights made in June. Other marine mammal sitings include one harbor seal observed outside the Deployment Area. LGL’s monthly progress report for beluga monitoring is attached for reference.
Pre-deployment hydroacoustic fish surveys
HDR AK has teamed with Aquacoustics (acoustic data analysis) and Kinnetic Laboratories (vessel and water quality) to complete split-beam hydroacoustic surveys supplemented with gill net and trawl sampling. The survey was initiated on May 28th. Four surveys were conducted on June 1, 10, and 17. A survey was attempted on June 8th but was aborted due to weather conditions beyond the limits of the sonar equipment and personnel safety. Weather and wave conditions have continued to impede data collection. The side-looking transducer (collecting near surface data) is especially adversely affected during rough sea conditions. Trip reports are attached for reference. The preliminary hydroacoustic data analysis indicates targets (representing fish) occur at higher densities in the upper water column but also occur throughout the water column (see attached figures). Additional figures are attached for reference. HDR|DTA is working with Aquacoustics for a more detailed data analysis comparing densities and distribution across surveys (tidal cycle, diurnal, depths and spatial distribution, and temporal trends).
Velocity Survey
TerraSond initiated mobile survey in the Deployment Area on June 19th. Data analysis is ongoing.
Geo-physical Survey
Activities Proposed for the July 2009
Beluga field observations planned for July consist of daily five-hour monitoring sessions scheduled to be conducted four days per week, for a total of 18 days.
The next hydroacoustic survey by HDR AK and Kinnetic Laboratories is scheduled to occur during the weeks of July 20 and 27, as outlined in the proposed schedule emailed to resource agencies on May 8, 2009. More detailed data analysis will be ongoing.
Surveys for velocity data will continue in July to cover different tidal cycles.

Re: LGL Monthly Progress Report June 2009
This is a progress report of a study by LGL Alaska Research Associates, Inc., sponsored by Ocean Renewable Power Company (ORPC) to monitor beluga whale presence, relative abundance, and behavior off of the north side of Fire Island, Upper Cook Inlet, Alaska. Information presented in this report provides baseline data on beluga whale presence, relative abundance, and surface behavior in and near the Cook Inlet Tidal Energy Project Deployment Area. This report covers project activities during May and June 2009.
A permit from Cook Inlet Region Inc.(CIRI; the local Native Corporation who owns the majority of Fire Island lands) was secured on May 13, 2009 to allow for a reconnaissance visit to the island on May 14, 2009. Concurrently, ORPC pursued a license from the United States Coast Guard (USCG) to utilize the Race Point Lighthouse Reservation lands for the observation site. USCG License HSCG-Z71117-09-RP-054L was executed on June 8, 2009 to allow observers to utilize the location for the observations. An observations site was selected near Race Point (Figure 1) that gave the maximum vantage of the Deployment Area (on a cliff 66 m above the mean low water line) while also allowing observers site access from pre-existing trails on the island.
Having secured the proper authorizations and established a preferred location for the observations, ORPC invited NMFS personnel to visit the site prior to the commencement of 2009 field operations. On June 15, 2009 Tamara McGuire and Chris Kaplan of LGL accompanied Kate Savage of NMFS to the observation site (Mandy Migura of NMFS was invited but unable to attend). During the visit, Kate Savage confirmed the viability of the site for making visual observations. ORPC has further applied for a supplemental USCG license to allow for a platform to be constructed on an existing foundation at the site that would improve the scope of visual observations, a modification that NMFS personnel agreed would be useful. Beluga field observations began on June 17, 2009 and were conducted on nine days between June 17 and June 30.
Objectives
The study has two primary objectives:
1. Estimate the frequency of occurrence, relative abundance, and surface behavior of beluga whales in and near the deployment area during ice-free months of 2009.
2. Provide information to ORPC and HDR/DTA on beluga whale sightings and locations relative to the Cook Inlet Tidal Energy Project.
Monitoring Effort
Monitoring was conducted on nine days during June 2009 (Table 1) from the observation
site near Race Point, Fire Island. An example of the 500 m x 500 m grid cell map of the project
area used to record whale locations is presented in Figure 1. Whale sightings are presented in
Table 2 and Figure 3.

Observation teams used chartered small fixed-wing aircraft to travel daily between
Anchorage and Fire Island. Observers looked for belugas during the flights, and used a 1,000 m
X 1,000 m grid cell map (Figure 2) to record the flight paths and any belugas sighted. Belugas
were not seen during any of the 18 flights made in June.

Environmental Conditions
Environmental conditions were recorded for every hour of observations. Sighting
conditions were ranked as good, fair, or poor (based on a combination of wind, whitecaps, rain,
and fog). Sighting conditions were reported as good on five days, fair on two days, and poor on
two days. Observers were able to see to the far shore (along the Susitna Flats) on all
observations days. Mean wind speed was 2.0 km/h, with values ranging from 0-16 km/h. Seas
were generally calm, with a mean Beaufort Sea State of 1.4 (1= ripples, without foam crests, and
2=small wavelets, crests do not break). Mean air temperature was 17.6o C, with values ranging
from 10-29o C. Rain was noted on two of the nine field days.
Vessels and Vessel Activity
The ORPC survey vessel was seen in or near the Deployment Area on seven of the nine
observation days. Other vessels were observed transiting in or near the deployment area: skiffs
were seen on four days; fishing boats were seen on two days; a tug was seen one day; and a tug
with a barge was seen on one day.
Beluga Whale Sightings
Belugas were sighted on five of the nine observation days (Table 2). No more than one
beluga group was seen per day. Calves were not seen, with the exception of one gray beluga
seen on June 30 that may have been a large calf (not young of this year). Locations of the
sightings of beluga whales from Fire Island during June 2009 are shown in Figure 3. On four
(June 19, 24, 25, and 29) of the five days on which belugas were seen, belugas were seen at
distance of approximately 7 km from the observation site, and observers had difficulty
determining beluga activity at these distances. Belugas seen on June 30 were seen closer (3 km)
to the observation site, and were observed travelling and diving. None of the beluga sightings
were within the tidal project’s Deployment Area (Figure 3).

Down looking transducer: Very little noise, no issues.
Side looking transducer: Significant noise with some data precluded by roll due to wave action.
Target verification: No active target verification was attempted.
Collection times: 2 ebb and 2 flood surveys. Final survey completed at sunset and near peak flood
due to the need to return to dock on the high tide.
Data Upload: June 1 at 11:00.
Incidental Observations:
Marine mammals: Harbor seal (2 occasions along transect number 2 at 12:30 and 21:30).
Birds: Numerous gulls flying and resting on large woody debris, two bald eagles on Fire Island.
Fish: One 6” silver fish (Eulachon?) in prop wash.
Boats: None
Other: Several large logs and lots of small woody debris.
Narrative:
The first data collection event occurred on May 28, 2009. HDR and Kinnetic Laboratories personnel
departed Anchorage from Ship Creek public boat launch aboard the research vessel North Forty at
approximately 9:30. The weather was 100% overcast with light rain. During transit the wind was
moderate at 15 knots from the SE and seas were three feet. The study site was leeward of Fire Island
and seas reduced to one foot (Figure 2-3). Light rain and variable winds to 10 knots continued for
the duration of the survey.
Two acoustic surveys were conducted on the ebb tide and two on the flood. The final survey was
initiated prior to sunset and completed just after sunset due to the need to return to dock on the high
tide (Figure 3). Transects were surveyed at 4 to 5 knots speed over ground and the duration of each
survey was approximately one hour. All equipment functioned properly. At times boat roll due to
wave action introduced noise into the side looking sonar and precluded a portion of surface data
collection.
Raw data files were uploaded to Aquacoustics ftp site on June 1 st .
The next survey is scheduled to occur on June 1 st .

Narrative:
The data collection event of June 8, 2009 was called off early due to sea conditions. HDR and
Kinnetic Laboratories personnel launched the RV North Forty from Ship Creek public boat launch at
9:00. The weather was mostly sunny and seas were less than one foot. The boat was docked at the
Port of Anchorage (POA) and the crew was oriented on port security procedures. The boat and crew
departed the POA dock at 12:45 (Figure 2). During transit the wind was moderate at 10 knots from
the SW and seas were one to two feet. The study site was not sheltered by Fire Island and seas
increased to three feet (Figure 3).
Gill net sampling was attempted while waiting for acoustic survey conditions to improve (Figure 4).
A 100 foot long by 8 foot deep experimental mesh (1” to 5”) monofilament gill net was fished on the
surface. The net was free drift through the study area near slack low and again in the opposite
direction on the flood tide. No fish were caught.
Twenty knot winds producing three foot seas were beyond the limits of the sonar equipment and
personnel safety and the event was postponed (figure 4).

Narrative:
The data collection event of June 10, 2009 had the most favorable sea conditions to date. HDR and
Kinnetic Laboratories personnel launched the RV North Forty from Ship Creek public boat launch at
10:30. The weather was mostly sunny and seas were less than one foot (Figure 2). Acoustic survey
data appeared clean and numerous targets were observed on the top side display near the surface.
Gill net sampling was attempted five times (Figure 3). A 100 foot long by 8 foot deep experimental
mesh (1” to 5”) monofilament gill net was fished on the surface. The net was free drift through the
study area near slack low and again in the opposite direction on the flood tide. Each drift lasted
approximately 30 minutes. Catch was one Eulachon at 205 mm FL and 1 Chinook salmon smolt at
120 mm FL.

Data Collection:
Down looking transducer: Some noise and wave action, no equipment issues.
Side looking transducer: Pitch and roll due to wave action exceeded equipment operating threshold.
Collection times: Two ebb and one flood surveyed. Final survey began before sunset and was
completed after sunset due to the need to return to dock near high tide.
Target verification: Target verification was conducted along the near shore transects. Gill net surface
drift two times at approximately 0.5 hours each. No catch. Surface trawl three times at
approximately 0.5 hours each. Catch included 10 salmon smolts ranging from 32 mm to 48 mm FL,
1 lamprey at 107mm, 1 snailfish at 100 mm, 110 small shrimp, 20 small amphipods.
Data Upload: Completed to Aquacoustics ftp site on June 18 at 13:00.
Birds: Numerous gulls flying and resting on large woody debris.
Fish: None
Boats: Tug and barge on route to POA at 23:00.
Narrative:
The data collection event of June 17, 2009 had the least favorable sea conditions to date Figure 2).
HDR and Kinnetic Laboratories personnel launched the RV North Forty from Ship Creek public
boat launch at 10:30. The weather was mostly cloudy and seas were one foot. Weather deteriorated
at the study with winds from Turnagain Arm reaching 25 knots and seas increasing to 3 feet.
Acoustic survey data collection was compromised due boat pitch and roll. Side looking data
appeared almost entirely precluded by waves.
Gill net sampling was attempted two times along the near shore survey transect. A 100 foot long by
8 foot deep experimental mesh (1” to 5”) monofilament gill net was fished on the surface. The net
was free drift through the study area near slack low and again in the opposite direction on the flood
tide. Each drift lasted approximately 30 minutes. No fish were caught with this method.
Trawl net sampling was conducted at the surface three times. A modified Isaac Kid style trawl
constructed of 1/4 inch mesh with a 1/8 inch zippered cod end and measuring 8 feet by 8 feet by 25
feet with aluminum frame and tow bar was deployed at approximately 125 feet behind the boat. The
tows lasted approximately 30 minutes each. Tidal current, wind, and waves made forward progress
and navigation difficult. Total catch was 10 salmon smolts (likely pinks) ranging from 32mm to 48mm
FL, 1 lamprey at 107mm, 1 snailfish at 100mm, 110 small shrimp, 20 small amphipods (Figures 4-6).
Representative specimens were preserved for further identification.
