Table comment: No population surveys have been conducted.
This subpopulation includes the Kara Sea (KS) and overlaps in the west with the Barents Sea subpopulation in the area of Franz Josef Land and Novaya Zemlya archipelagos. Data for KS and the Barents Sea, in the vicinity of Franz Josef Land and Novaya Zemlya, are mainly based on aerial surveys and den counts (Parovshivkov 1965, Belikov and Matveev 1983, Upenski 1989, Belikov et al. 1991, Belikov and Gorbunov 1991, Belikov 1993). Telemetry studies of movements have been done throughout the area, but data to define the eastern boundary are incomplete (Belikov et al. 1998, Mauritzen et al. 2002).
