Global Range: Locally abundant in the high Arctic. Local concentrations occur in Davis Strait, Baffin Bay and adjacent waters, and the Greenland Sea. Smaller numbers occur in Hudson Strait, northern Hudson Bay, Foxe Basin, and Barents Sea. Presence in the Beaufort, Bering, and eastern Chukchi seas is exceptional. Also occurs in "Soviet" Arctic (Leatherwood and Reeves 1983). Most common in the eastern Canadian arctic and west Greenland area (IUCN 1991, which see for further details on distribution).
