Marine Bird Winter Surveys in Prince William Sound – 2023
Of the marine birds that overwinter in Prince William Sound (PWS), Alaska, nine species and one species group were initially injured by the 1989 Exxon Valdez oil spill (EVOS; Exxon Valdez Oil Spill Trustee Council, 2014). This Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) commissioned study, now in its third year, conducted marine bird and marine mammal surveys in under-surveyed areas in and around the PWS tanker escort zone.
