Summary
Whales are the largest krill-predators at South Georgia (SG), yet their impacts on krill stocks are poorly understood. Recently, whale surveys revealed high summer abundance and extended use of SG waters into winter, coincident with a krill fishery. This project measures how whale foraging intensity varies across the feeding season in SG, using UAV-based measurements of body condition and satellite-tracking of diving rates to measure season-specific krill consumption, and inform krill quota-setting for the Subarea 48.3 CCAMLR krill risk assessment.
