This data set captures the tag release and recovery information for sablefish from the early 1970s until present. It also contains tag release and recovery data for several other species (shortspine thornyheads, Greeland turbot, Pacific sleeper sharks, spiny dogfish, and lingcod) which have been tagged by NMFS in AK since the late 1990s.

The dataset contains trawl and seine catches from Southeast Alaskan estuaries sampled from 1995 to 2008. The data also include physical variables (temp, salinity, turbidity), and shorezone shoreline classifications.

This archive information package contains fish presence and stream habitat data collected in southeast Alaska, between May 2017 and October 2020 to identify anadromous fish stream habitat. During this time the Alaska Department of Fish and Game Habitat Section staff completed 1,051 stream surveys in remote and urban areas, using backpack electrofisher, fish traps, clinometers, tape measures, and rangefinder/hypsometer. Data collected include fish species presence, notable fish habitat features, substrate characteristics, fish barriers, and other additional notes. These data are provided in both Excel spreadsheet and ESRI shapefile formats.

The Southeast Alaska Coastal Monitoring (SECM) project in Alaska was initiated in 1997 by the Auke Bay Laboratory, National Marine Fisheries Service, to study the habitat use and early marine ecology of juvenile (age-0) Pacific salmon (Oncorhynchus spp.) and associated epipelagic ichthyofauna. This research has been conducted to meet several needs identified in the National Oceanic and Atmospheric Administration (NOAA) Fisheries 2006-2011 Strategic Plan, the North Pacific Anadromous Fisheries Commission (NPAFC) 20062010 Science Plan, and the Gulf of Alaska Global Ocean Ecosystem Dynamics (GLOBEC) Program.

A 2007 pilot study was initiated by the University of Alaska – Southeast in which baseline levels of contaminants, including persistent organic pollutants (POPs) and total mercury, were determined in whole bodies of juvenile coho salmon collected in streams in and near national park units in the Southeast Alaska Inventory and Monitoring Network. Although the concentrations of POPs determined in the juvenile coho were relatively low (< 10 ng/g, wet weight), the preliminary findings of this study indicate that, in the Glacier National Park region, salmon from streams with higher density of spawners had increased levels of certain banned chlorinated pesticides (i.e., alpha-chlordane, o,p’-DDT, p,p’-DDD) compared to salmon collected in other streams with lower salmon spawning density. A follow up study will be initiated in spring/summer 2015 to determine concentrations of POPs in resident salmonids, as well as benthic macroinvertebrates collected from five streams that have fish barriers near or adjacent to Glacier National Park. Comparisons in contaminant concentrations and patterns will be made for fish collected below and above the barrier in each stream to help determine if certain classes of POPs are being transported by the spawners. As part of this study, the NWFSC will analyze whole bodies/muscle of salmonids and benthic macroinvertebrate samples POPs using gas chromatography / mass spectrometry (GC/MS). Percent lipid content of samples (with adequate sample mass) will also be determined. These data will be included in a report to the NIH-sponsored IDeA Network of Biomedical Research Excellence. Determining levels of persistent organic pollutants in salmonids and macroinvertebrates.

The Alaska Fisheries Science Center's Status of Stocks and Multispecies Assessment (SSMA) Programs Fishery Interaction Team (FIT) conducted a fish survey in the marine offshore waters of the Beaufort Sea during the month of August, 2008. The Mineral Management Service (MMS) provided funding for the survey. The results of the survey provided estimates of abundance, species composition and biological information of marine fish and invertebrates, oceanographic properties and information on the macro- and micro- zooplankton communities.

This dataset contains water temperature, salinity, currents, and other parameters taken during four field campaigns that occurred in LeConte Bay (near LeConte Glacier) in southeast Alaska in August 2016, May 2017, July 2017, September 2017, and September 2018. Supported by the National Science Foundation Polar Programs through projects LeConte Glacier and LeConte Bay Ice-Ocean Interactions. During each cruise we collected water column temperature, salinity, and depth data using a CTD. In addition, we collected water velocity data from two pole-mounted ADCP systems situated off the side of the vessel, a 600 kHz to capture upper layer velocities in more detail and a 150 kHz ADCP to reach the bottom and characterize the entire water column flow. Data were taken from MV Steller (21m fishing vessel) and MV Pelican (7.6m landing craft). In addition, we collected multibeam sonar data of the seafloor and glacier ice front during both campaigns. We had a RESON multibeam sensor mounted on a pole, with a 15 degree wedge inserted to enable collection of near vertical ice faces. This accession does not include these bathymetry data.

A database describing a 67-year time series for Sashin Creek pink salmon (Oncorhynchus gorbuscha) data is presented. The database details the survival and other biological parameters of the pink salmon population living in Sashin Creek, a pristine environment in Little Port Walter, Baranof Island, Alaska. We assembled all the published and unpublished biological and environmental data pertaining to this population, which has been evaluated almost continually by researchers since 1934. We developed a database using Microsoft Access that includes annual estimates of the freshwater and saltwater survival for these fish. The database contains the daily counts of the number of emigrating fry and escaping adults during their annual migrations since 1934, and their lengths, weights, or fecundity. Environmental parameters in the database include stream temperature, stream discharge, daily minimum and maximum air temperatures, and precipitation where Sashin Creek enters seawater at Little Port Walter. All records have been evaluated and transformed to ensure comparability. References for all data are provided, including unpublished sources. The Sashin Creek Weir Database (SCWDATA) can be accessed through the Internet.

Swimming depth and water temperature were recorded every 3 minutes during the 2002-2004 spawning migration for Yukon River Chinook salmon tagged with radio-archival tags. Telemetry data, obtained using remote tracking stations and aerial surveys, were used to determine the upriver movements of the fish. Ninety-five tags were recovered, including 35 tags returned by fishermen and 60 tags retrieved during spawning ground surveys.

These data consist of larval (< 60 mm) and age-1+ (> 60 mm) Capelin CPUE (Catch per unit effort) from various catch efforts throughout the Gulf of Alaska (GOA) from 1996 – 2017. The dataset contains the following information: fishing gear type, date, time, catch location (latitude and longitude), tow distance, number of capelin caught, and CPUE for capelin greater than and less than 60 millimeters. Gear types include beach seines and trawls.
