註釋Systematic aerial surveys were conducted in the southeast Beaufort Sea on 19-24 August and 6-11 September 1983 to document the numbers and distributions of bowhead whales and of other marine mammals. The study area extended from 141 W (Alaska-Yukon border) eastward to 128 40 W (near Cape Bathurst), and from the 2 m depth contour northward to about 25 km north of the 100 m depth contour, except between 141 W and 138 W where the northern boundary was at 70 20 N. The northernmost 25 km sections east of 138 W also extended beyond the 200 m depth contour, and thus included the steep shelf break beyond the shallow continental shelf.
