The Belugas that summer in the eastern Canadian high Arctic appear to winter off the West Greenland coast (Figure 2), there- fore we refer to them as the Baffin Bay population. Belugas concentrate in traditional summer estuar- ies, particularly those of Somerset Island, from mid-July to mid-August (Heyland 1974; Sergeant and Brodie 1975; Finley 1976; Smith et al. 1985). Estuarine concentrations of Belugas occur at Creswell Bay, Cunningham Inlet, Elwin Bay, and Garnier Bay on Somerset Island, Maxwell Bay on Devon Island and Brodeur River and Cape Kater on the Brodeur Peninsula, Baffin Island. In late sum- mer. Belugas disperse southward through Peel Sound as far as northern Franklin Strait and estuar- ine concentrations have been observed around southeastern Prince of Wales Island (Coningham Bay) in late August (Finley and Johnston 1977). Belugas do not usually penetrate much further west than western Barrow Strait. In September, Belugas exit Lancaster Sound and move northeastward toward Greenland (LGL 1983). Catch statistics indicate a southward migration along the West Greenland coast to wintering grounds south of Disko Island (Degerbol and Neilsen 1930; Vibe 1950; Kapel 1977). As many as 500 Belugas over- winter in flaw leads in the northern periphery of the "Northwater" (Finley and Renaud 1980). Aerial sur- veys have identified overwintering grounds of Belugas in Davis Strait off southwest Greenland (67° to 70°N) where the majority of whales occurred in pack-ice within 50 km of the coast (McLaren and Davis 1981, 1983; Heidi-Jorgensen et al. 1992). None was observed in the open wat
