Dataset: Marine mammal (whale and penguin) sightings from Chile to the Western Antarctic Peninsula from multiple cruises in the Southern Ocean from 2001-2002 (SOGLOBEC project)

Visual surveys for cetaceans and penguins were conducted during daylight hours on all days when weather conditions allowed on the Antarctic Peninsula, in the austral autumns and winters of 2000-2002.

Objectives: 1) to characterize foraging behavior and movements of individual baleen whales in relation to prey characteristics and physical environment, 2) to relate distribution, abundance and biomass of baleen whales species to same for krill in a large area in a single season, and 3) to monitor interannual variability in whale distribution and abundance in relation to physical environment and prey characteristics.
