Project objectives and description

My PhD is part of a Marsden Fund project to investigate the role of snow cover in the evolution of Antarctic sea ice to test the hypothesis that a persistent snow cover can prevent or slow a decline in Antarctic sea ice in response to a warming climate. Specifically, we want to

1) quantify the optical properties of snow on sea ice in Antarctica,

2) quantify the insulating properties of snow on sea ice and the thermal transfer across the  ice-snow-atmosphere boundary in Antarctica, and

3) predict the impact of increasing temperatures and changes in the snowpack on Antarctic sea ice evolution.

For my PhD, I will combine field and laboratory measurements with modeling to improve the representation of snow processes in predictive models of sea ice evolution in the context of climate change. The combination of measurements and modeling will reduce the uncertainties in sea ice models through improved process understanding and improved parametrizations and will provide insight into the differences between sea ice evolution in Antarctica and the Arctic.
