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.
