Sea Otter Surveys of Yakutat Bay and Adjacent Gulf of Alaska Areas - Cape Hinchinbrook to Cape Spencer from 1995-08-07 to 1996-05-23 (NCEI Accession 9800017)
Sea otter sighting data including location; point locations for the beginning and end of each transect were programmed into an aircraft global positioning system, each sea otter sighting was recorded by hand on a data sheet by the observer. Sea otter density was estimated from the aerial counts and applied to the entire study area for an estimate of population abundance. Distribution Survey: 8-9 August 1995 (Cape Suckling to Cape Spencer); 19-23 August 1996 (Cape Hinchinbrook to Cape Suckling). Abundance Survey: 7-9 August 1995 (Yakutat Bay)
