Research Associate

Room 213.17 , IMAS Hobart

Doctor Eva Cougnon is a research associate in ocean temperature extremes. Her research interests are in ocean and climate dynamics, ocean temperature extremes and their potential predictability. Ocean temperature extremes can have severe impacts on the marine coastal ecosystems, for some fisheries and in aquaculture. Eva wants to understand what drives these events in order to predict them and better inform decision making and assist stakeholder engagement. She also has a great interest in regional oceanography, in particular near Antarctica, and the understanding of the interactions between the ocean and the Antarctic ice shelves and the sensitivity of water mass formation to the ocean-cryosphere interactions. This will help to better understand/estimate the impact of the sea level rise due to Antarctic ice shelf melting.


Before starting her current research associate position Eva undertook a PhD in physical oceanography at the University of Tasmania, using a regional model to study the sensitivity of water mass formation near the Antarctic continent.

Research Themes

Eva’s research contributes to the UTAS research theme of Marine, Antarctic and Maritime. She has two main interests:

  • Ocean climate extremes, such as ocean temperature extremes around Australia and their potential predictability;
  • Ocean-ice shelf processes that can influence the lower limb of the overturning circulation.

Current projects

Predictability of marine extremes:
