Harbor Seal Pup

The Polar Ecosystems Program conducts research and monitoring on pinnipeds in the Arctic, sub-Arctic, and Antarctic marine ecosystems. The research projects focus primarily on abundance, trends, distribution, and foraging behavior of harbor, bearded, ringed, spotted, and ribbon seals in Alaska. The primary objectives of the program are to support management and assessment of population status under the Marine Mammal Protection Act, and to gain a better understanding of the factors responsible for the dynamics of populations and their roles in the ecosystem. 

Program Leader: Peter Boveng
