Understanding Antarctic and Arctic marine ecosystems by exploring biodiversity and resilience to environmental change is critical for making policy decisions that will lead to effective stewardship and sustainable management of marine resources. This strand of research combines existing long-term data with new field-based and experimental observations to explore the impact of environmental change on marine ecosystems.

Sustained Monitoring of Whales at South Georgia

It is now estimated that >30,000 whales visit South Georgia in summer, making this sub-Antarctic island the highest-density UK hotspot for recovering whales, including critically endangered Antarctic blue whales. The …



Hungry Humpbacks

Whales are the largest krill predators in the UK Overseas territory of South Georgia, yet their impacts on krill stocks are poorly understood. Recently, whale surveys revealed high summer abundance …
