OSTI ID:415944
We estimated the summer and winter abundance of marine birds in Prince William Sound, Alaska, following the 1989 Exxon Valdez oil spill, examined changes in population size between pre-spill and post-spill surveys, and compared pre- to post-oil spill population trends in the oiled zone of the Sound relative to trends in the unoiled zone. Ninety-nine species of birds were observed on surveys. Estimated populations of 15 to 32 species/species groups demonstrated declines over the 17-19 year period between pre- and post-spill surveys. However, because of the long time period between surveys, we could not directly associate overall population declines with the oil spill.
