Abstract: Surveys have documented overall declines in Prince William Sound (PWS) marine bird populations between the early 1970’s and the years after the EVOS. Recent surveys detect a significantly lower sea otter density in oiled coastal areas. The meaningful restoration of marine bird and sea otter populations requires periodic estimates of populations to determine whether recovery is occurring or if declines are continuing.

This project will conduct population estimates of marine birds and sea otters in PWS using a stratified random sampling design. Population estimates for each species and species groups will be added to other post-EVOS population estimates to determine population trends. Data gathered will provide valuable information on the distribution and habitat use of marine birds and sea otters. Survey methods are flexible enough to provide for collection of more detailed information if requested by investigators of other studies.
