Monitoring Seabird Populations in Areas of Oil and Gas Development on the AlaskanContinental Shelf: Oceanic, Shelf and Coastal Seabird Assemblages at the Mouth of a Tidally-Mixed Estuary (Cook Inlet, Alaska)

摘要

Surveys were conducted in July, 1992 to study the distribution and abundance ofseabirds in a 12,500 sq km area of lower Cook Inlet, Alaska. Seabirds at the sea surface, fish below the surface (estimated acoustically), and sea surface temperature and salinity were recorded on 415 ten-minute transects covering 1225 linear km. Sea temperature and salinity (CTD) profiles of the water column and zooplankton tows were obtained on stations crossing the entrance to Cook Inlet.
