These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing fish morphology data from summer surveys in Prince William Sound, Alaska. Data includes: date, time, latitude, longitude, fishing method, fish common name, total length, fork length, weight, and whether or not that fish was saved. Various catch methods were used to obtain fish samples for aerial and hydroacoustic validations, including: modified herring trawl, purse seine, beach seine, gillnet, cast net, dip net, and jig.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing fish aerial validation data from summer surveys in Prince William Sound, Alaska. Data includes: date, location, latitude, longitude, aerial ID, validation ID, total length and validation method. Various catch methods were used to obtain fish samples for aerial validations, including:cast net, go pro, hydroacoustics, jig, dip net, gill net, purse seine, photo and visual identification.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This datasets consist of multiple tables (one for each sample station and frequency), providing echointegration data from forage fish survey transects in Prince William Sound, Alaska. Each file contains analysis exports from EchoView Software Pty Ltd. ver. 7.1.29.30212.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing the results of surveys conducted to document the summer at-sea distribution and abundance of marine birds and mammals in Prince William Sound, Alaska. Surveys followed standard U.S. Fish and Wildlife protocols for strip surveys. Data include: transect ID, date, time, latitude, longitude, record number, data type, animal species, count, behavior, plumage, distance, observers, observer conditions, the altitude of the survey, ice presence, trip ID, beaufort, transect type, transect width, and comments.

This data package contains one table with morphometric and diet information for "non-die-off" seabirds captured and collected in southcentral and southwest Alaska. Data pertains to birds captured (live) or collected (lethally) including, bird identification numbers, sampling dates, geographic locations, body measurements, diets (from either stomach contents or regurgitated prey), and sex and age of the bird when discernible. Common Murres (Uria aalge) and Black-legged Kittiwakes (Rissa tridactyla) were captured from their breeding colonies in lower Cook Inlet, Alaska, 2016-2023. Kittiwakes, murres, Glaucous-winged Gulls (Larus glaucescens) and Horned Puffins (Fratercula corniculata) were collected in Prince William Sound, Cook Inlet, and Unalaska.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing: age, length, weight, dry mass energy density, and dry mass of forage fish (Pacific sand lance and capelin) captured in July in Prince William Sound, Alaska.

This dataset consists of two tables: 1) forage fish catch and size data from hydroacoustic trawl transects, and 2) taxonomic details of fish species collected around two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing zooplankton biomass data from samples collected in the upper 50 m of the water column during summer surveys in Prince William Sound, Alaska. Data include: date, time, latitude, longitude, depth, species identification, and biomass.

This dataset consists of one table with Area Backscattering Coefficient (ABC) data from hydroacoustic transect surveys collected around two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska.
