This summer an international team of researchers worked on the British Antarctic Survey led research project “Hungry Humpbacks: Measuring seasonal foraging intensity at South Georgia.” You helped to support this project which received funds from the South Georgia Heritage Trust, Friends of South Georgia Island, and was also supported with a Darwin Plus grant for UK Overseas Territories.

Whales are the largest krill predators in South Georgia (SG), yet their impacts on krill stocks are poorly understood. Recent whale surveys have revealed high summer abundance and extended use of SG waters into winter, which coincides with use by a krill fishery. To better understand how whales impact krill, this project measures how whale foraging intensity varies across the feeding season in SG. This is achieved using drones to measure body conditions and satellite tracking of diving rates to measure season-specific krill consumption.
