Impact of Southern Westerly Winds and Circumpolar Deep Water on climate and marine ecology

Research project investigating how shifting southern westerly winds drive warm Circumpolar Deep Water onto the West Antarctic Peninsula shelf, accelerating glacier melt, reducing sea ice, and transforming marine ecosystems.

Climate and Ice during the Last Interglacial

This project studies the last Interglacial (129-116 thousand years ago, ka) when CO2 and global temperature were both higher than they were before human industrialisation. By examining Last Interglacial climate, we can gain insights into climate processes and feedbacks close to those expected by the end of the 21st century.

West Antarctica wind strength and atmospheric circulation

This project used ice core chemical and biological tracers, including marine diatoms swept onto the ice sheet by wind, to reconstruct 300 years of wind strength and atmospheric circulation patterns in West Antarctica.

Late Quaternary changes in the Westerly Winds over the Southern Ocean

In this NERC-funded project, we are generating Southern Hemisphere Westerlies (SHW) proxy records from each of the three major sectors of the Southern Ocean, focusing on subantarctic islands situated in the core belt of the SHW.
