About the research project

Sea ice forms an ephemeral thin veneer between ocean and atmosphere. The evolution of this layer is governed by a complex interplay between ocean and atmosphere. In the last decade we have observed the two largest winter sea ice extents and the three smallest summer extents in a 44 year-long observational record. What is driving this increased variability, and are we in the midst of a regime shift in Southern Ocean sea ice?

This project aims to:

  • Elucidate causal mechanisms behind the recent increase in variability in Southern Ocean sea ice;
  • Understand the role of long-term ocean warming on sea ice dynamics, and explore the potential for tipping points related to subsurface ocean warming; and,
  • Compare the relative future importance of enhanced ice shelf melt, atmospheric warming, oceanic warming, and wind changes on sea ice.
