My project involves studying the dynamics and heat content of the Arctic Ocean. Specifically, I am investigating what happens to the heat that enters the Arctic from the Atlantic, which circulates around the entire Arctic basin as an Atlantic Water current below 200 m depth. There is enough heat stored in this Atlantic Water to melt all Arctic sea ice within a few years if it was to be brought to the surface in this time. It is therefore important to understand more about where and how this warm Atlantic Water travels, and the mechanisms behind how its heat mixes with other water masses in the Arctic. Investigating how these processes and Atlantic Water heat input are affected by local and remote changes in sea-ice and atmospheric conditions is also key given today’s changing climate.
I hope to tackle these questions using a variety of models, along with data from ice-tethered profilers and long-term moorings in the Arctic.
