Winter use of sea ice and ocean water mass habitat by southern elephant seals: The length and breadth of the mystery

Understanding the responses of animals to the environment is crucial for identifying critical foraging habitat. Elephant seals (Mirounga leonina) from the Kerguelen Islands (49°20′S, 70°20′E) have several different foraging strategies.
