Obsolete - AFSC/RACE/EcoFOCI: 2011 Chukchi Sea Cruise MB11-01/1MB11

A total of 64 stations were occupied along onshore-offshore transect lines from the Bering Strait to Barrow Canyon.  At each station we sampled zooplankton using a 1m^2 Tucker Sled with 333 micron mesh nets.  One net was fished entirely along the bottom.  The second net collected zooplankton from the bottom to the surface.  Inside this second net was a 150 micron mesh, 25 cm diamter Clarke-Bumpus net to collect the smaller zooplankton species.  Both Tucker nets had a calibrated General Oceanics flow meter mounted inside the net mouth.  A SeaBird FastCat (SBE 49) was attached to the top of the Tucker Sled  to determine the depth of the samplers in real time and to measure temperature and conductivity.  A multi-frequecy acoustic systems (TAPS-6) was also mounted on the top of the sled frame for acoustic determination of zooplankton biomass and size composition.  The device insonified a small volume directly in the path of the net.
During the cruise we recovered a multi-frequency acoustic device that had been moored off of Icy Cape for almost one year and then deployed two more acoustic devices to overwinter.

AFSC/ABL: Longline Sablefish Survey

Data is available from annual bottom longline surveys conducted cooperatively by Japan (1979-1994) and the U.S. National Marine Fisheries Service, Alaska Fisheries Science Center (1988-present). Starting in 1988, the U.S. started conducting the survey, creating overlap between the two countries between1988-1994. Since 1994, the U.S. has conducted the survey independently. Stations are spaced systematically (~20-30 km apart) along the slope from the eastern Gulf of Alaska west to the Aleutian Islands and north into the eastern Bering Sea. At each station, depths from ~150-1000 meters are sampled. Each year the captain attempts to set the gear along the same path. The same stations are sampled each year except in the Aleutian Islands and the Bering Sea, which are sampled every other year at the beginning of the survey (last week of May-early June).  Since 1995, in odd years the Bering Sea stations are sampled and in even years the Aleutian Islands are sampled. The status of each hook is recorded. Lengths are taken from major species including, sablefish, giant grenadier, Pacific grenadier, Greenland turbot, arrowtooth flounder, Pacific cod, shortspine thornyhead, and all rockfish caught.

Obsolete - AFSC/RACE/EcoFOCI: 2011 Gulf of Alaska IERP Cruise TN263/1TT11

A total of 105 stations were occupied.  There were two sample grids (southeast Alaska and Yakutat Bay) and two transects in the vicinity of Kayak Island.  At each station we sampled using paired 20 and 60 cm Bongo frames (150 and 500 micron mesh nets, respectively) and a Sameoto neuston sampler (500 micron mesh net) to estimate the abundance of zoo- and ichthyoplankton.  A SeaBird SeaCat (SBE 19 plus) was used with the bongo frames to determine the depth of the samplers in real time and to measure temperature and conductivity.  At a few selected stations depth-stratified plankton were obtained with a 1 meter squared MOCNESS (500 micron mesh nets) and at other selected stations microzooplankton were sampled with vertical tows of a CalVET net (53 micron mesh).

AFSC/ABL: Salisbury Sound sponge recovery

In 1995, an area of the seafloor near Salisbury Sound was trawled to identify immediate effects on large, erect sponges and sea whips. Video transects were made in the trawled areas, as well as in reference areas with a manned submersible. One year later, the video transects were repeated to characterize medium-term survival and recovery of the sponges and sea whips. In 2009, the site was revisted to document the long-term effects of trawling. Thirteen years after trawling, the incidence of damage to sponges and sea whips in the trawled areas was higher than in the reference areas. Sponge density was also lower in the trawled areas.

AFSC/RACE/SAP/Long: Data on the effects of release density on release success in hatchery-reared red king crab

This data is from an experiment designed to test the viability of using hatchery reared crab to supplement wild stocks and to determine the optimal density for future releases.  Crab were released by divers into 5 x 5 m quadrats marked with ground line at three densities: 25, 50, and 75 m-2.  Researchers monitored the crab density inside the plots, in order to estimate survival, as well as outside the plots, to estimate crab movement.  In addition, they determined predator densities and performed tethering experiments on red king crab to see if predator density or predation risk differed among the density treatments.

AFSC/ABL: Juvenile chum salmon allozyme stock identification, Bering Sea 2002

Genetic stock identification techniques were used to identify the origin and provide stock-specific migration and distribution patterns of juvenile chum (Oncorhynchus keta) salmon caught during annual fall surveys (2002) along the eastern Bering Sea (Fig. 1). Preliminary results indicate that: 1) Yukon River Fall chum salmon are widely distributed from offshore of the Yukon River, eastward to 62B0N, 172B0W, and as far south as Nunivak Island (60B0N), suggesting a southwesterly migration pathway along the Bering Sea shelf; 2) juvenile chum salmon from the Kuskokwim River are narrowly distributed south of Nunivak Island from the mouth of the Kuskokwim River, south to 58B0N, and as far west as 168B0W, suggesting a westerly migration pathway along the Bering Sea shelf; and 3) northern Russia juvenile chum salmon stocks (mainly stocks from rivers draining into the Gulf of Anadyr) are distributed as far east as 62B0N, 171B0W (Fig. 2). These results are unique in that they represent the first attempt to identify early marine distribution and migration of juvenile chum salmon stocks on the eastern Bering Sea shelf.

AFSC/ABL: Naknek sockeye salmon scale time series

A time series of scale samples (1956  2002) collected from adult sockeye salmon returning to Naknek River were retrieved from the Alaska Department of Fish and Game. These scales were digitized, revealing growth information for the freshwater and marine life history stages of sockeye salmon. The growth information will be related to time series of sockeye salmon production to Bristol Bay and oceanographic conditions within the Bering Sea and North Pacific Ocean.

AFSC/RACE/MACE: Results of 2012 acoustic trawl survey Bogoslof DY1202

Scientists from the Midwater Assessment and Conservation Engineering (MACE) program of the Alaska Fisheries Science Center (AFSC) Resource Assessment and Conservation Engineering (RACE) Division conducted an acoustic-trawl (AT) survey of walleye pollock in the southeastern Aleutian Basin near Bogoslof Island aboard the NOAA ship Oscar Dyson during 7-15 March, 2012.  The survey was designed with two survey tracks, which covered 3,656 nmi2 of the CBS Convention Specific Area.  The primary survey track was nearest to the Aleutian Islands and consisted of 35 north-south parallel transects spaced 3 nmi apart and the second survey track was located just north of the primary survey track, and consisted of 12 north-south parallel transects space 9 nmi apart.  These second survey track was essentially northern extensions of the primary survey track, designed to observe whether walleye pollock were present in deeper water. The survey followed established AT methods as specified in NOAA protocols for fisheries acoustics surveys and related sampling.

AFSC/ABL: Origins of salmon seized from the F/V Arctic Wind

Samples of chum (Oncorhynchus keta), sockeye (O. nerka), and chinook salmon (O. tshawytscha) seized from the F/V Arctic Wind were analyzed to determine their region of origin using genetic stock identification (GSI), otolith marks, and parasite analysis.  Based on the analysis, the chum salmon samples originated in Russia, 63%; Japan, 14%; western Alaska, 11%; Alaska Peninsula and Kodiak, 6%; PWS/southeast Alaska, 4%, and British Columbia, 1%. The origins of the sockeye salmon sample were Russia, 24%; Alaska/northern British Columbia, 75%; and southern British Columbia/Washington, 2%.  The origins of the chinook salmon sample were Russia, 44%; western Alaska, 23%; southcentral Alaska, 6%, and California/Oregon/Washington, 27%. No chinook salmon were detected from southeast Alaska or British Columbia.

AFSC/ABL: Southeast Coastal Monitoring Survey (SECM)-juvenile salmon and associated epipelagic ichthyofauna in the marine waters of Southeast Alaska

SECM research was initiated in the spring of 1997, just prior to the onset of a strong El Nio event, and has continued annually. SECM sampling occurs around Icy Strait (58N, 136W) in the northern region and have been sustained for 18 years. This is a principal migration corridor for salmon that transit dynamic tidal and oceanographic features to offshore waters as juveniles and return in subsequent years as adults. SECM researchers have compiled a multi-year time series of biophysical data associated with juvenile salmon culled from monthly sampling intervals in May, June, July, and August. Juvenile salmon and ecologically-related species are sampled with a surface trawl and associated oceanographic measurements are taken. This time series includes data on: Temperature and salinity profiles, Surface nutrients and chlorophyll, Zooplankton (upper 20-m and integrated), Size, abundance, and origin of salmon
Potential predators of juvenile salmon, Some of these biophysical data are being used to forecast pink salmon returns to Southeast Alaska and to evaluate recent trends in commercial salmon harvest and ocean survival within the region. These analyses also explore the impact of large-scale, climate-driven processes on salmon year-class strength.

AFSC/ABL: Rockfish Habitat Dive Video Transects

Many species of commercially valuable rockfish (Sebastes spp.) inhabit waters on the outer continental shelf in the Gulf of Alaska typically between depths of 100-300m. The benthic habitat requirements and spatial distribution of these rockfish species is relatively unknown. Information regarding benthic habitat use would improve current stock assessments and provide baseline information for an ecosystem approach to management. Several study areas in the Gulf of Alaska have recently been mapped with high resolution multibeam bathymetry and backscatter to generate detailed benthic habitat maps. Large populations of rockfish have been surveyed and harvested within these mapped areas. The NMFS MESA group conducted two submersible observation surveys in summer 2005 on three of these mapped areas, Albatross Bank, Hazy Islands, and Cape Ommaney. The objectives of these surveys were to collect information on rockfish  habitat interactions and generate density estimates by habitat. Forty dive transects were completed on the mapped sites using the Delta two-person occupied submersible. We identified numerous gravid females and observed schooling behavior of several species over particular benthic habitats. Density estimates of rockfish using strip and line of sight methodologies are being determined by substrate and invertebrate habitat classification. We identify habitat types with high densities of rockfish species and describe differences between estimation methods.

AFSC/ABL: 2009 Chum Salmon Bycatch Sample Analysis  Bering Sea

A genetic analysis of samples from the chum salmon (Oncorhynchus keta) bycatch of the 2009 Bering Sea walleye pollock (Theragra chalcogramma) trawl fishery was undertaken to determine the overall stock composition of the sample set. Samples were genotyped for eleven microsatellite markers and results were estimated using the current chum salmon microsatellite baseline. In 2009, genetic samples were collected opportunistically as part of a special project, but sample biases have the potential to affect stock composition analysis results. Consequently, stock composition estimates apply to the sample set and may not represent the entire chum salmon bycatch.  Based on the analysis of 1,437 chum salmon bycatch samples collected throughout the 2009 Bering Sea trawl fishery, North Asian (30%), East Asian (34%), and Eastern Gulf of Alaska/Pacific Northwest (18%) stocks dominated the sample set, with smaller contributions from Western Alaska (13%), Upper/Middle Yukon River (2%), and Southwest Alaska (4%) stocks. The estimates for the 2009 chum salmon bycatch sample set were similar to the 2005 chum salmon bycatch estimates.

AFSC/ABL: Autonomous underwater vehicle for tracking acoustically-tagged fish 2010

Autonomous underwater vehicles (AUVs) are increasingly being used to collect physical, chemical, and biological information in the marine environment.  Recent efforts have been made to merge AUV technology with acoustic telemetry to provide information on the distribution and movements of marine fish.  During 2010, we conducted a study in coastal waters near Juneau, Alaska to determine the feasibility of using AUVs to locate marine species under rigorous field conditions, and to compare this approach with traditional vessel-based tracking.  Tracking surveys were conducted with a REMUS 100 AUV equipped with an integrated acoustic receiver and hydrophone.  The AUV was programmed to navigate along predetermined routes to detect acoustic transmitters within the area.  Comparable surveys were conducted with a boat equipped with acoustic tracking gear.  Moorings with transmitters at 20-500 m were deployed to provide acoustic targets at known locations and depths.  Marine fishes and crabs were tagged to provide mobile targets.  Transmitter depth had a major impact on tracking performance.  The AUV was equally effective or better detecting reference transmitters in shallow water, and significantly better than the boat for transmitters at deeper depths.  Similar results were observed for the tagged animals.  Crabs at moderate depths were recorded by both tracking methods, while only the AUV detected fish at depths exceeding 500 m.  The AUV periodically had difficulty navigating and maintaining course due to the strong currents and extreme depths in the area.  AUVs with greater cruising speeds, increased operating depths, and improved navigation would enhance AUV performance in marine environments.
