Estimating Abundance of Seals in a Drifting Environment: 2005: Pup Production of Harp Seals, Pagophilus groenlandicus, in the Northwest Atlantic
Photographic and visual aerial surveys to determine current pup production of northwest Atlantic harp seals were conducted off Newfoundland and Labrador (the “Front”), and in the Gulf of St. Lawrence during March 2004. Surveys of four whelping concentrations were conducted between 5 and 18 March res...
