title: Data on abundance of age-0 northern rock sole and benthic environmental variables in nursery grounds of eastern Kodiak Island, Alaska, NPRB Project 301, Geographic WGS84, Summers 2002-2004, Stoner, A.

description: These data are part of a study detailed in Stoner et al. 2007 (Stoner, A.W., M.L. Spencer and C.H. Ryer. 2007. Flatfish-habitat
 associations in Alaska nursery grounds: use of continuous video records for multi-scale spatial analysis. J. Sea Res. 57:137-150),
 and other works in progress.
Northern rock sole (Lepidopsetta polyxystra) recruit as larvae to shallow near-shore waters throughout the Gulf of Alaska which provide nursery 
grounds during the first post-settlement summer. Three bay systems on the eastern end of Kodiak Island, Alaska (Shakmanof Bay, Monashka Bay, Middle Bay),
have been identified as important nurseries for the species. During August of 2002, and July of 2003 and 2004, a towed camera sled was used in each Bay to
quantify the density of age-0 northern rock sole and characterize the habitats occupied by the species. In August 2002 two additional sites were also surveyed: 
Neva Cove and Twin Creeks Beach. Variables considered included depth, bottom-water temperature, sediment characteristics, sediment surface bedform, and biotic 
features such as worm-tube mats and densities of various other metrics such as sea stars, bivalve shells, algae, etc. Data for each 15-60 second interval of
video suitable for counting age-0 flatfish are included in Excel 2003 spreadsheet format (“Age-0 northern rock sole NPRB 301”). An analysis of the 2002 data 
set have been published in Stoner et al. (2007) (see above), and the combined data for 2002 through 2004 are currently under analysis using generalized additive 
modeling at the Alaska Fisheries Science Center.
 These datasets were archived as part of the North Pacific Research Board legacy project recovery effort undertaken by Axiom Data Science and NPRB in 2025. The goal of the recovery effort was to assess the NPRB-funded data projects from 2002 to 2014 and archive final data packages that were ready for publication to increase long-term accessibility and discoverability. Data packages were archived as is given limited funding and resources.

title: Pollock and salmon behavior in pelagic trawls, Bering Sea 2002, Rose, C.

description: NPRB project R0202, applied advanced sonar technology and underwater video in a cooperative industry /government effort to identify
 ways to modify pelagic trawls to reduce salmon bycatch in Alaska pollock fisheries. The Dual-frequency Identification SONar (DIDSON) provided
 detailed observations of the behavior of these two species within pelagic trawls. Observations in conventional trawls fueled initial separation
 concepts based upon behavioral differences. Sonar imagery was supplemented with underwater video to for dentification and confirmation purposes.
 Ambient conditions (depth, light level and temperate) at the trawl were recorded with a sensor/logger. The position of the towing vessel (F/V Gladiator)
 was recorded at the start and end of each tow and at intervals thoughout towing. These datasets were archived as part of the North Pacific Research Board legacy project recovery effort undertaken by Axiom Data Science and NPRB in 2025. The goal of the recovery effort was to assess the NPRB-funded data projects from 2002 to 2014 and archive final data packages that were ready for publication to increase long-term accessibility and discoverability.

title: NPAFC Salmon Tagging, North Pacific Ocean, Bering Sea and Pacific Rim Countries, June 2003-July 2006; Helle, J.H.

description: This project addressed the 2003 priority of the North Pacific Research Board for research on factors 
 affecting salmon stock dynamics, mortality, and migration throughout their range and life cycle. From June 2003- July 2006, 
 595 electronic data storage tags (DSTs) and 862 disk tags were released during the Bering-Aleutian Salmon International Survey 
 program of the North Pacific Anadromous Fish Commission. To date, 50 DSTs have been returned from this program, mostly from 
 chum (n=25) and sockeye (n=12) salmon. Almost all were from maturing fish released in summer and fall and came primarily from 
 Japan (21), Russia (13), and western Alaska (10). New types of data acquired include the first overwintering marine data from 
 Pacific salmon (two years of sea temperature and depth data from a Yukon River Chinook salmon) and the first salinity data from a 
 migrating Pacific salmon. Depth data confirm that Chinook and chum salmon have deeper vertical distributions (average daily maxima: 
 Chinook: 130 m; chum: 58 m) than those of sockeye (22 m), pink (37 m), and coho salmon (46 m). Temperature ranges varied widely among 
 water masses traversed by maturing salmon, while maximum daily depths remained fairly uniform. This indicates that salmon chose maximum 
 depths and not temperature ranges, and that usual depths of maturing salmon may remain relatively constant across water masses and ocean areas. 
 The results of this scientific data collection project are preliminary.

description: The dataset is composed of environmental and biological samples collected to develop a PCR protocol for detecting and monitoring
 the parasitic dinoflagellate (Hematodinium sp.) that is the causative agent of Bitter Crab Syndrome. Environmental samples include water
 and sediment samples from Southeast Alaska. Bloodsmear samples were collected in 2003 from the Gulf of Alaska and the Eastern Bering Sea 
 continental shelf. Blind samples for PCR development were collected from Southeast Alaska (2003), Gulf of Alaska (2003) and Eastern Bering 
 Sea (2003, 2004), Newfoundland, Canada (2003, 2004) and British Columbia (2003). Reference samples for the PCR protocol were submitted by 
 colleagues from Scotland, UK (2003), Newfoundland, Canada (2003) and Maryland, USA. The data is presented in an Microsoft Excel spreadsheet.

title: AFSC/RACE NPRB_1016 An annotated checklist of the marine macroinvertebrates of Alaska and a retrospective analysis of the groundfish trawl database.

description: A comprehensive species list of marine invertebrates of Alaska has been
 lacking. The checklist of Austin (1985) treated the marine invertebrates of the
 southern coast of Alaska to California and since then many new species have been
 described, many range extensions have been discovered, and considerable changes in
 higher-level systematics have been made. The checklist we compiled lists over 3,500
 species and includes the currently accepted scientific name and its significant
 synonyms, common names, type localities, geographic and depth distributions, a
 general statement of abundance in Alaska when known (e.g., rare, uncommon, common,
 abundant), and general remarks. This checklist will serve as a foundation for future
 species-specific research. Updated species lists are necessary to reflect the
 current state of biodiversity knowledge and are thus essential for conservation
 planning and management. To monitor and predict future changes to marine life, the
 distribution and abundance of marine species need to be better understood, and this
 can only be achieved with reliable identifications based on a sound taxonomy. The
 current status and future directions of Alaskan marine invertebrate biodiversity are
 briefly discussed. These datasets were archived as part of the North Pacific Research Board legacy project recovery effort undertaken by Axiom Data Science and NPRB in 2025.

title: Bristol Bay Sockeye Salmon Parent Escapement/Return and Smolt Data, 1949-2009, Ruggerone, G.T.

description: Kvichak sockeye salmon, once the largest sockeye stock in the world (up to 50% of world’s sockeye production),
 declined 73% during brood years 1991-1999 compared with previous years. This investigation examined factors associated
 with the decline and implication for salmon management.
Parent escapement and return by age (brood tables) and smolt data were obtained from databases initially developed by D.E. Rogers,
University of Washington. Catch and return data were collected by the Bureau of Commercial Fisheries, Fisheries Research Institute
(FRI), and Alaska Department of Fish and Game (ADFG). These databases were updated in recent years using statistics provided by
L. Fair, ADFG, and statistics in annual ADFG smolt reports (Crawford 2001). The brood table statistics used in this investigation
include catches from Bristol Bay districts only (“inshore returns”). Salmon catches that occurred in Area M fisheries
and in high seas fisheries (mostly prior to mid-1970s) were not included because they are subjected to greater allocation error between
salmon regions and among Bristol Bay stocks. Total return estimates reported by ADFG include all sockeye salmon captured in the False
Pass, Unimak Island, and Shumagin Island areas even though other stocks of salmon are known to mix in these fisheries (D. Eggers, ADFG,
pers. comm.). Ultimately, use of the inshore versus total return brood table probably had little or no effect on qualitative conclusions
about Bristol Bay salmon population dynamics drawn from brood table data.
Recently reconstructed escapement and brood table data for the Alagnak River stock were provided by D. Eggers, ADFG, and obtained from
Clark (2005). This reconstruction led to significant changes in the Alagnak brood table compared with the previous table maintained by
ADFG. A greater proportion of the Naknek-Kvichak District catch was assigned to Alagnak. Re-allocation of Naknek-Kvichak catch had a
negligible effect on Kvichak brood table statistics.

title: Bering Sea wintering grounds of beluga whales, 2006, Hobbs, R.

description: The intent of this project was to identify and define the winter habitat of beluga whales in the Bering Sea and determine
 which stocks of whales were moving along the coast of the Chukotka Peninsula in the fall. In November-December 2003 and
 October-November 2004 field projects were conducted in an area of Lavrentia Bay where belugas have regularly occurred in
 the weeks before ice formation. In 2003 and 2004, beluga did not enter the study area and were not reported in other parts
 of the bay. Local knowledge indicated that the sequence of ice formation had recently changed with ice forming in the bay prior
 to ice formation in the Bering Strait rather than the other way around and the beluga had no reason to enter the bay. At this
 same time the Canadian collaborators in this project succeeded in attaching tags to whales from this same population in July
 that lasted through the winter and in one case for over 400 days. With the increased tag longevity there was no need to continue
 trying to capture beluga in Lavrentia Bay during the fall. Consequently the project was refocused to capture beluga in the Anadyr
 River during the summer, and develop a tag that could be deployed from the ice edge during the winter in Lavrentia Bay when captures
 with a net are not possible. To this end a field project was conducted in late August 2005. Unfortunately the salmon runs that bring
 beluga near shore in August ended during the first week of this field project and there were no opportunities to capture whales.
 A second field project was planned for early August 2006 during which 1 whale was caught and a transmitter attached which continues
 to transmit as of the writing of this report. During weather days in the 2004 and 2005 field seasons harpoon deployment systems were
 developed, to date no opportunities to attach these to belugas have occurred. A field season in the Anadyr River is planned for August
 2007 to attach the remaining transmitters, including trials of the harpoon attachment system.

title: Salmon Science in Alaska: An Analysis of Current Research and Monitoring. Knudsen, E.E. 2007.

description: Millions of dollars are being spent annually on salmon research in Alaska. Salmon research problems are ecologically and biologically complex, cover a huge expanse of marine, estuarine,
 and freshwater habitats, and are being studied by numerous research organizations and programs. Concerns have been raised about the efficiency of this spending, and whether the most important
 management-oriented questions are being addressed. The purpose of this project was to gather the necessary metadata on salmon research and monitoring so decision-makers could determine whether
 additional funding is warranted for salmon research and for what research topics. The objectives of this project were therefore to 1) identify and communicate with principal salmon research managers,
 2) build and populate a database for housing and analyzing salmon research and monitoring metadata, and 3) analyze salmon research and funding metadata to describe the extent of funding for existing
 research, areas of potential redundancy, and unmet research needs. Although insufficient research metadata detail was gathered for a reasonable gap analysis, the project research database contains
 457 records of recent salmon studies, and the monitoring database contains 13,533 records of salmon monitoring in Alaska. Salmon research has been summarized by species, life history stage, bioregion,
 disciplinary topic, research issue, and management information needs. Summary information has also been provided on funding for salmon research and monitoring in Alaska. A web-served query system, that
 allows users to search for research projects through a spatially explicit interface, as well as through a query builder, was also produced during this project. These datasets were archived as part of the North Pacific Research Board legacy project recovery effort undertaken by Axiom Data Science and NPRB in 2025. The goal of the recovery effort was to assess the NPRB-funded data projects from 2002 to 2014 and archive final data packages that were ready for publication to increase long-term accessibility and discoverability.

title: BSFRF Bristol Bay red king crab trawl survey stock assessment, 2007. Hughes & Goodman

description: The Bering Sea Fisheries Research Foundation (BSFRF) cooperating with the National Marine Fisheries Service (NMFS)
 conducted a 40 day assessment survey of Bristol Bay red king crab (BBRKC) in late May-early July 2007 aboard the chartered
 120 ft F/V American Eagle using specialized trawl gear, a new survey design and new analytical methods. The BSFRF survey
 was coordinated with the long standing NMFS survey of this resource to test the hypothesis that a different trawl design,
 a new survey methodology and principals of geostatistics would estimate mean and variance of BBRKC abundance with more accuracy
 and precision than the standard NMFS annual trawl survey. Final plans for the 2007 BSFRF assessment survey were completed
 in April 2007 following a successful pilot study conducted during the summer of 2005 and testing of purchased survey gear
 and trawl mensuration sensors during the fall of 2006. The 2007 BSFRF survey was conducted over an approximate 24,000
 square nautical mile region consisting of 241 random site tows. The area swept estimates for each trawl tow were accurately
 measured by the trawl mensuration equipment and estimates benefited greatly from use of a new and improved trawl bottom contact
 sensor developed by NMFS. The new survey gear, sampling methodology and goestatistics proved highly effective and generated more
 precise BBRKC abundance estimates than those from the standard NMFS survey in the same area and time. Precision estimates (95% CI)
 for large male BBRKC from the standard NMFS survey have averaged +/- 37% over the past 10 years compared to +/- 13% from the BSFRF
 survey. A standard normal test for a difference in population means (Z-test) was used to test the differences between BSFRF and
 NMFS surveys. Results showed statistically significant higher estimated mean abundance and reduced variance from the BSFRF survey
 for all sizes and sexes of BBRKC. Separate from the assessment survey, the F/V American Eagle and the two NMFS survey vessels
 worked together over a two day period and completed a planned pilot study of 20 paired side by side tows. Results are discussed
 and being used to design further comparative trials. These datasets were archived as part of the North Pacific Research Board legacy project recovery effort undertaken by Axiom Data Science and NPRB in 2025.

title: Bowhead whale single nucleotide polymorphisms (SNP) loci and genotypes, Bering Sea, 2005-2010, Morin, P.

description: Bowhead whales (Balaena mysticetus) were hunted to near extinction in the North Pacific early in the previous century,
 but population sizes have recovered substantially since cessation of commercial hunting. Aboriginal hunting in both Russia and
 Alaska continues, however, and proper management requires better understanding of stock structure. Studies of mitochondrial DNA
 (control region) and microsatellites indicated possible stock structure. A new type of genetic marker, single nucleotide polymorphisms
 (SNPs), is becoming a valuable tool for assessing genetic diversity in wild populations. SNP technology allows efficient and cost
 effective genotyping of many loci and/or modern or historical samples. We examined differentiation between populations of bowhead
 whales using SNP genotyping in combination with traditional mitochondrial and nuclear microsatellite data. We developed 42 bowhead
 SNP assays included 17 independent SNPs and 25 linked SNPs. Sampled populations of bowheads included Okhotsk Sea (n= 47),
 Bering/Chukchi/Beaufort Seas (BCB) (n=483) (including 62 historical bone and baleen samples), and Hudson Bay and Davis Strait
 stocks of eastern Canada (n= 50). Population differences have been confirmed for the Okhotsk Sea and eastern Canada; comparison
 with the larger BCB sample set is planned. Further analyses of substructure within the BCB stock will be conducted using the SNP
 data, and in comparison to results from published mtDNA and microsatellite studies. The SNP data also constitute baseline population
 genetic data for bowheads, allowing continued genetic monitoring and analysis of bowhead populations.
 The data set contains a table of single nucleotide polymorphisms (SNP) genetic loci that were discovered from sequencing bowhead whale DNA,
 assays that were developed for genotyping a subset of those loci, and the genotypes generated from bowhead whale samples from the three populations. These datasets were archived as part of the North Pacific Research Board legacy project recovery effort undertaken by Axiom Data Science and NPRB in 2025. The goal of the recovery effort was to assess the NPRB-funded data projects from 2002 to 2014 and archive final data packages that were ready for publication to increase long-term accessibility and discoverability.
