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 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.

This dataset includes zooplankton biomass from Prince William Sound, Icy Bay and Yakutat Bay, Alaska. Zooplankton were sampled with a ring net (0.6 m diameter with 211 µ mesh) on a 50 m vertical haul or to within 5 m of the bottom in shallow water. Zooplankton samples were identified to species and life stage when possible.

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 concentrations of inorganic nutrients (NO2, NO3, PO4, and SiOH4) in water samples collected during summers from multiple depths at sampling stations throughout Prince William Sound, 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 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.

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.
