This project consists of two components: (1) provision of analytical services for the stable isotope ratio investigations associated with Exxon Valdez oil spill projects, and (2) an investigation of food web relationships and trophic interactions of harbor seals and other top consumers of Prince William Sound (PWS). Through the use of harbor seal tissues collected from native harvested animals and tagging programs, seasonal and migrational information has been obtained with regard to prey utilization and trophic status at differing locations within the sound and the adjacent Gulf of Alaska. Preliminary results indicate that within PWS, harbor seals fall at the …
