Diets of hooded seals in coastal and drift ice waters along the east coast of Greenland
To provide data on the feeding habits of hooded (Cystophora cristata) seals in the Greenland Sea, seals were collected for scientific purposes on expeditions with R/V”Jan Mayen”, conducted in the pack ice belt east of Greenland in September/October 1999 and 2002 (autumn), July/August in 2000 (summer...
