Title: Isotope Ratio Studies of Marine Mammals in PWS
Project Year and Number: 1997: 97170
Principal Investigator (PI): Donald Schell, University of Alaska Fairbanks
Assisting Personnel: Amy Hirons
Research Location: Prince William Sound, Gulf of Alaska
Restoration Category: Research
Injured Resources Addressed: Harbor Seals
Abstract: This project uses natural stable isotope ratios to assess trophic structure and food webs in Prince William Sound and contributes to the studies by ADFG personnel to determine the reasons for the decline of harbor seal populations. Through a mix of captive animal studies, comparison of isotope ratios in archived and current marine mammal tissues and their potential prey species in Prince William Sound, insight into environmental changes causing the decline may be possible. In addition, by providing analytical services for mass spectrometry the project contributes to the SEA (/320) program's effort to describe the food chains supporting commercial fishes impacted by the oil spill.
