Sea otter (Enhydra lutris) abundance and distribution in the Gulf of Alaska west of Prince William Sound were surveyed by helicopter in the spring of 1989 at the time of the Exxon Valdez oil spill and the following fall. Estimated population sizes did not significantly decline between spring and fall for areas with comparable survey data. No significant (p>0.05) shifts of sea otter distributions in heavily, lightly and unoiled areas were detected between spring and fall surveys.
