摘要

The overall purpose of this study was to obtain baseline data on the abundanceand distribution of marine bird and sea otter populations in Lower Cook Inlet during summer and winter. The authors' primary objectives were to: (1) develop population estimates, with 95% confidence intervals, of marine birds and sea otters in Lower Cook Inlet during summer 1993 and winter 1994; (2) examine marine bird and sea otter distributions within Lower Cook Inlet and map these in a geographical information system; and, (3) determine the relative abundance and densities of marine bird species groups within the Inlet during summer 1993 and winter 1994 and compare these data with data from previous surveys of Lower Cook Inlet and Prince William Sound.
