lacier Bay National Park comprises a relatively pristine marine environment, and hosts a variety of marine predators such as humpback whales and seabirds. Variability in the abundance and distribution of these predators may be linked to changes in the availability of SSF, but little is known about the biology, abundance or habitat use by SSF in the Glacier Bay ecosystem. We are studying SSF and predators using similar methods employed in the Cook Inlet Seabird and Forage Fish project, including hydroacoustic surveys, trawls, and seines to study SSF, and pelagic surveys to assess the abundance and distribution of marine predators. Funded by USGS (Base and NRPP funds), and Glacier Bay National Park. Reduced field work will take place in FY00.
