In the Mackenzie Estuary and southeast Beaufort Sea, beluga distribution and habitat use have been studied primarily using aerial surveys and satellite telemetry throughout the summer and fall.

The summer distribution of beluga whales (Delphinapterus leucas) in the Sea of Okhotsk is typical for boreal and subarctic seas that are seasonally ice covered and support numerous anadromous fish species. During summer in the Sea of Okhotsk, beluga whales aggregate where rivers flow into estuaries, gulfs, and bays.

Beluga whales are currently found in Sakhalinskiy Bay (in an estuary of. The beluga, Delphinapterus leucas, is a medium-sized toothed whale, which becomes completely white when it reaches sexual maturity around seven years of age. Adult males attain a length of meters and females meters.

In contrast to the clumped distribution during the summer aggregation in the Mackenzie Estuary, beluga distribution across the Beaufort Sea and Darnley Bay is typically widespread, and consists almost exclusively of single individuals or small groups of 2 or 3 whales (Norton and Harwood, ; Harwood et al.,Harwood and Kingsley, ).Cited by: 5.ABSTRACT: The summer distribution of beluga whales (Delphinapterus leucas) in the Sea of Okhotsk is typical for boreal and subarctic seas that are seasonally ice covered and support numerous anadromous fish species.
