The Southern Ocean hosts globally unique and important ecosystems characterized by extreme environmental variability. Superimposed upon this, these systems are now experiencing climate change impacts at rates greater than the global average. Antarctic krill ‚ÄövÑv¨ an ecologically and commercially important species ‚ÄövÑv¨ are highly adapted to their variable polar environment. At annual scales, krill have evolved a life cycle synchronized to seasonal oscillations between productive open-ocean habitats in the summer, and sea ice-dominated habitats in the winter. At interannual scales, krill recruitment is episodic and highly dependent upon highquality habitat, created by optimal environmental conditions occurring every 4-5 years. This project therefore aims to improve understanding of the environmental drivers of krill habitat quality and population success in both open-ocean and sea-ice habitats, in order to better assess their current status and continued survival in a changing Southern Ocean. In the open ...
