title: National Status and Trends: Bioeffects Program - Kachemak Bay Database

description: This study was based on the sediment quality triad (SQT) approach. A stratified probabilistic sampling design was utilized
 to characterize the Kachemak Bay system in terms of chemical contamination, sediment toxicity and benthic
 infaunal community structure. The purpose was to define the extent and magnitude of toxicity and other biological effects associated
 with contaminants in the Kachemak Bay system. Five strata (Homer harbor, Western intertidal, Western
 subtidal, Eastern intertidal, and Eastern subtidal) were established in the shallow (less than 10 fathoms) northern area of the bay.
 Sediment samples were collected at multiple stations in each strata. A broad suite of sediment contaminants
 were analyzed at each station, including polynuclear aromatic hydrocarbons (PAHs), chlorinated pesticides including DDT and its metabolites,
 polychlorinated biphenyls (PCBs), trace elements, and butyl-tins Other parameters included
 grain size analysis, total organic/inorganic carbon (TOC/TIC), and percent solids. Characterization of infaunal assemblages and the abundance
 of organisms present in sediments provide additional information to help determine areas of
 degraded sediments. Whole sediment toxicity bioassays with two species of amphipod were conducted to test for overt contaminant toxicity.
 This project provides invaluable baseline data on sediment infauna species richness, chemical
 contamination and toxicity that is georeferenced and posted on the internet through the NOAA's National Status and Trends data portal. 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: COASST Alaska Beached Bird Data, September 2007-June 2009, Parrish, JK

description: COASST Alaska Beached Bird Data include beached bird data from the Coastal Observation and Seabird Survey Team (COASST). COASST is a citizen
 science program in coastal Alaska, Washington, Oregon and California that trains people living in coastal communities to gather highly rigorous and
 independently verifiable data on beach-cast birds, human use of beaches, and beach oiling. Started in 1998, COASST now supports more than 500 volunteers
 monitoring over 300 coastal sites. In this project, COASST was maintained in six communities in Alaska (St. Paul, St. George, Cold Bay, Seward,
 Homer, Sitka) and extended to six more (Dillingham, Kodiak, Juneau, Ketchikan, Unalaska, Kenai), with the goal of comparing the initial patterns
 of data from Alaska to those from similar programs in the lower 48. Between September 2007 and June 2009, COASST conducted 14 training sessions,
 established relationships with 16 partner organizations, and recruited more than 100 participants to survey 53 year-round and 19 seasonal beaches.
 Within the same time period, 733 surveys were collected and include records on 259 carcasses. 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: Habitat Mapping and Production Estimates of Skate Nursery Sites in the Eastern Bering Sea, NPRB Project 808

description: Four Alaska skate nursery sites in the eastern Bering Sea were investigated
 using an autonomous underwater vehicle. Data collected at each site included
 thousand of high resolution digital images, bottom depth, and bottom temperature.
 Analysis of images suggests egg cases were highly aggregated over extremely small
 areas on flat sandy to muddy bottom. Bottom temperatures ranged between 3.23-4.14
 degree C at all sites and varied little ate any one site. Nursery sites occurred at
 greater depths and cooler waters with increased latitude. A comparison of direct egg
 case counts at nursery sites with recruit estimates from bottom trawl surveys and
 production models suggested a mismatch between the two by several orders of
 magnitude. Explanations include uncertainty in the recruitment models and trawl
 estimates or the existence of many more nursery sites in the eastern Bering Sea for
 the Alaska skate. Embryo development time was documented in the laboratory through
 controlled experimental temperatures at 4.2 degree C and 5.4 degree C The results
 showed that water temperature is a key determining factor in embryo development
 time. At the warmest experimental temperature (5.4 degree C) it is projected embryo
 development will take 2.9 years and at the cooler (4.2 degree C) it is estimated to
 take 3.7 years. 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: BSFRF Bristol Bay red king crab trawl survey stock assessment, 2008. Hughes and Goodman

description: The Bering Sea Fisheries Research Foundation (BSFRF) cooperating with NMFS and ADFG conducted a second
 full survey of Bristol Bay red king crab (BBRKC) in late May - June 2008 under NPRB project 825, as continuing
 work of NPRB project 625. The 2008 survey used the same specialized trawl gear with a NETMIND trawl mensuration
 package aboard the same chartered vessel the F/V American Eagle. The area swept for each trawl tow was accurately
 measured by the trawl mensuration sensors and the use of the NMFS newly designed bottom contact sensor developed for
 the 2007 survey that provided the ability to measure on-bottom time of the trawl. Survey methodology relied on results
 from a 2005 pilot study for design, conduct and analysis of full-scale assessments for 2007 and 2008 of the BBRKC stock.
 The 2008 survey sampling was conducted in 30 days at sea with an experienced scientific crew of four. The survey was
 conducted over approximately the same 24,000 sq.nm. region as in 2007, consisting of 255 random site tows. Fourteen
 additional stations were added along the eastern edge of the survey area in 2008 to expand survey coverage over the
 eastern-most distribution of the BBRKC. As in the prior year survey, the 2008 survey methodology and gear proved highly
 effective. The specialized trawl is believed to have a crab catchability coefficient near 1.0 resulting in a more accurate
 measure of adult and small sized juvenile crab densities. The large number of stations sampled and the application of
 geostatistics generated higher precision BBRKC biomass estimates than estimates from the standard NMFS survey in the
 same area and time. BSFRF research for 2008 provided for a 2nd year of consistent comparative survey results. Abundance
 and biomass estimates and station catch rates have been compared with the standard NMFS survey for the same region.
 Results have been shared with NPRB, ADFG and NMFS and presented at a formal peer review workshop in the spring of 2009
 where a working agreement was reached for current implementation of project 825/625 results and for future research
 application. 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: The development of a catalog of left-side digital images of individually-identified Cook Inlet beluga whales Delphinapterus leucas, NPRB Project 0910

description: LGL’s Photo-identification Study of endangered Cook Inlet beluga whales (CIBWs) Delphinapterus leucas has demonstrated
 that CIBWs in Upper Cook Inlet (UCI) possess persisting natural marks that can be identified and re-sighted photographically.
 Our catalog of images of the right sides of CIBWs photographed 2005-2010 has provided information about the distribution and 
 movement patterns of individual CIBW and the population in general, including residency/movement patterns, habitat utilization, 
 reproduction, injury, disease, mortality, and abundance. Due to budget constraints, we archived all photographs taken of the 
 left-sides of CIBWs after 2005 and were unable to process and catalog these images. Funding from NPRB allowed us to catalog 
 images of the left-sides of CIBWs photographed 2005-2008, and to develop the left-side catalog. The left-side catalog increased 
 the existing information about identified CIBWs, without requiring additional field work, research permits, or potential disturbance 
 to the whales. A total of 186 CIBWs were identified as individuals from left-side images, including 58 mothers, and 20 whales 
 identified on both sides of the body. The creation of a left-side catalog allowed for increased representation of whales seen 
 in Turnagain Arm, and added to the records of 255 CIBWs in the right-side catalog, increased the evidence that CIBWs do not 
 display fidelity to any single area of UCI, that individuals move among Knik Arm and the Susitna River Delta, and Turnagain Arm, 
 and that CIBWs are not divided into subgroups. All CIBWs are therefore likely exposed to multiple potential threats that may 
 be endemic to certain areas of UCI. 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: Iliamna Lake Freshwater Seal Study: Characterizing Local Use Patterns, Local Traditional Knowledge, and Seal Population Ecology

description: In response to concerns about the absence of information on Iliamna Lake’s seal population, the tribal communities
 of Iliamna, Newhalen, and Kokhanok partnered with the Bristol Bay Native Association, University of Alaska Anchorage,
 and National Marine Mammal Laboratory (NMML) to gather baseline information on seasonal shifts in seal abundance and
 distribution, subsistence harvest levels, and local traditional knowledge (LTK). To gather LTK, this project recruited
 and trained local research assistants (LRAs) from the communities of Iliamna, Kokhanok and Newhalen. LRAs conducted 143
 subsistence household surveys (SHS) in 2010 and 2011, and identified key respondents for follow-up interviews. Data were
 compared to studies conducted by ADFG in 2004 and 2005, and findings suggest that seal harvest levels are no higher now
 than in the past. LRAs were also trained to collect biosamples from locally harvested seals, but samples were only returned
 from one seal. This single sample will be genetically analyzed for species identity. A total of twelve aerial surveys were
 over haulout locations identified from previous survey work and key respondent interviews. These documented large seasonal
 changes in seal abundance and distribution, with a peak during the August molt season, when salmon are most abundant in the
 lake. Pups were first seen during surveys in mid-June and no longer discernable by mid-August. This project is now working
 to integrate western and local knowledge, so that an accurate synthetic understanding of the role of seals in the human and
 lake ecosystem can be developed. 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: Reduction of bycatch mortality for non-target crab species in the commercial snow crab (Chionoecetes opilio) fishery

description: Crab fisheries in Alaska use baited pots to capture crab and bring them to the surface. Only males of
 a minimum size can be retained while females, smaller males, and crab from non-targeted species must be returned
 to the sea. The process of sorting and discarding non-retained crab results in bycatch mortality of unknown magnitude,
 under some conditions estimated to be up to 100%. Recent regulations recognize the importance of considering all sources
 of fishing mortality, mandating that bycatch mortality must be considered when setting catch limits. Currently a rate
 of 50% mortality is applied to the crab discarded from pot fisheries in Alaska, but it is widely acknowledged further
 work is needed on both refining this estimate and reducing discarded crab losses. We used an index of crab reflexes
 recorded during the commercial snow crab fishery to investigate the predicted discard mortality rate. The method known
 as Reflex Action Mortality Predictor (RAMP) has been developed for both fish and invertebrates. Rates from 22 commercial
 vessels were found to be generally low, averaging 5.9% although rates climbed significantly when windchill temperatures
 at the sorting table were below -10 degrees C. Low numbers of observations at the lowest temperatures and lack of
 observations during comparable windchill exposures confounded the analysis.

title: Storm surge, ocean wave, and weather remodeling of coastal sandy beach in the eastern Bering Sea. 2009-2010. Smolen, M. J., S. Johnson, and R. Tuluk

description: Climate change is expected to alter weather patterns leading to changes in the paths
 and frequency of storms in the Bering Sea. Such changes are reflected in the observations
 by people in Native villages along the coast that these storms are now more frequent, of
 greater magnitude, and extend the usual storm season. This research is a direct result of
 the concern by Hooper Bay and Paimiut about erosion and flooding and they identify this as
 a primary concern for the welfare of their community. This research estimates the effects
 of ocean waves and weather driven storm surge events on erosion and accretion processes on
 the sandy beaches and Nuok Spit that protects Hooper Bay. The 2009 profiles, with three replicates,
 of sections of beach indicate that the beaches grew in height in the upper reaches of the beach
 when compared to 2010 profiles. The growth is believed to be from wind blown sand from the splash
 zone to the bluffs. Overall erosion was not documented in the interval from late July to early August
 2009 to 2010. 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: NPRB_924: DNA-based identification of larve and dietary components

description: Accurate identification of various life history stages and prey items of marine fishes and invertebrates is central for understanding distribution, abundance, trophic ecology, and
 biodiversity of these species. Taxonomic approaches have been successfully applied to ichthyoplankton identification and diet analysis efforts for many years. Identification to the species
 level requires varying degrees of taxonomic expertise. and diagnostic characters for eggs or larvae in some species have not been elucidated. Prey remains may be too digested for consistently
 accurate identification to the species level.Here we developed a mitochondrial DNA (mtDNA) database and laboratory protocols to accurately identify any life history stages of commercially
 important fish species, with special emphasis on those species that have been difficult or impossible to identify by conventional taxonomic means. Results from this study have the potential to
 fill important knowledge gaps for commercially and ecologically important species routinely studied at the Alaska Fisheries Science Center (AFSC), especially for ichthyoplankton
 identification, species composition in fish diets and forensic identification for law enforcement. The database provided the foundation for development of rapid, cost-effective, and accurate
 molecular protocols to identify species under circumstances where traditional taxonomic approaches founder or fail. 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.
