Behavioural and population biology of walruses, and seals
Principal Investigator: Stirling, Ian
Licensed Year(s): 1990 1988 1987
Summary: To capture and mark walruses; to observe behaviour of marked walruses; to describe reproductive ecology of Atlantic walrus overwintering in the Central High Arctic; to tape record underwater vocalizations of marine mammals; to evaluate the biological importance of polynyas to the overwintering populations of marine mammals; to study distribution of overwintering populations of seals in relation to...

Licence #5019
Principal Investigator: Stirling, Ian
Licensed Year(s): 1985
Summary: Use sub-ice recording to study distribution of overwintering populations of seals in relation to plynyas, sea ice conditions, patterns of freeze-up, distribution of ringed seal pupping areas, distribution of polar bears and proposed winter shipping lanes....
