Two species of cetacea, the beluga whale (Deiphinapterus leucas) and the bowhead whale (Balaena mysticetus), are seasonal migrants to the southeastern Beaufort Sea and Amundsen Gulf
, both within the Inuvialuit Settlement Region (ISR) in Canada's Western Arctic (INAC, 1984).
A westward migration was pronounced at King William Island (with simultaneous eastward migration) and Amundsen Gulf
, while northward movements were important at Banks Island and Melville Island.
The movements of tagged belugas into the polar pack and into passages of the Canadian Arctic Archipelago suggest that aerial surveys conducted in the southeastern Beaufort Sea and Amundsen Gulf
may have substantially underestimated the size of the eastern Beaufort Sea stock.
An intermediate dwell-time mode was located offshore along the edge of the Beaufort Sea pack ice, and smaller modes were evident within Amundsen Gulf
and in a travel corridor between the Mackenzie Estuary and M'Clure Strait.
In eastern Amundsen Gulf
, 1974 was the most severe ice year on recent record, with the latest date of clearing of the landfast ice (6 September), the earliest date of new ice formation (4 October), and the fewest number of open water days (28 days).
Frank continued as surveyor while the navigation system was moved along the coast, from Isachsen to Mould Bay, to Tuktoyaktuk, and into Amundsen Gulf
We did not detect a strong regional difference in benthic community characteristics, observing only a lower richness in the Amundsen Gulf
region than in the neighboring Beaufort Sea region.
Berrimilla entered the North West Passage from the Amundsen Gulf
and sailed south of Victoria Island, through Dease Strait, Victoria Strait and Peel Sound and out into Barrow Strait and Lancaster Sound.
They believe that control must be exerted over submarine traffic, and have even suggested that listening stations be established in Lancaster Sound and the McClure Strait and in Amundsen Gulf
Rounding the southern shoulder of Victoria Island, he passed through Coronation Gulf to present-day Amundsen Gulf
, which opens to the Beaufort Sea.
The land area south of the proposed route extending east from Prudhoe Bay until just past the mouth of the Amundsen Gulf
contains high ice content (ice lenses) soils.
For the three-and-a-half weeks I was on board, we navigated the ice in the Amundsen Gulf
, the westernmost reach of the Northwest Passage, some 90 miles south of the Polar Ice Cap.
