Distribution of Harp and Hooded Seals in Offshore Waters of Newfoundland
Surveys conducted in offshore waters of Newfoundland and Labrador (NAFO Div. 2J and 3KL) between 1991 and 1993 indicate that both harp seals (Phoca groenlandica) and hooded seals (Cystophora cristata) were present in offshore waters during the winter. Hooded seals appeared to utilize the slope edge...
