Child Item 6: Zooplankton Biomass Data from Gulf of Alaska Fjords, 2010-2011

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR 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.

Child Item 04: Forage Fish Aerial Validation Data from Prince William Sound, Alaska

This is a child item of the USGS Data Release: https://doi.org/10.5066/F74J0C9Z One table with data used to validate aerial fish 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.

Child Item 5: Modified Herring Trawl Fish Catch Data in Gulf of Alaska Fjords, 2004-2011

This is a child item of the USGS Data Release: https://doi.org/10.5066/F7K072DR This dataset contains catch data from trawls at the sampling stations. We deployed a modified herring trawl in coastal waters within glacier fjords of Alaska. Sampling stations in each fjord were chosen randomly from a 2.5 x 2.5 km grid overlaid on navigable waters in the fjord. The number of stations in each fjord was chosen to achieve a sampling frequency of about 1 sample per 15 km^2, and was based on available resources and logistical constraints (weather, navigational hazards and vessel time).
