Analytical Models of Ice Sheets and Ice Shelves
2020Simple mathematical models for ice sheets and ice shelves are described which provide important insights into their dynamics. The models studied can be solved analytically to give equilibrium surface profiles and velocity distributions. Consideration is given to the feedback between surface elevation and mass balance.

The flow and fracture of Antarctic Ice Shelves
2023This thesis explores the deformation of glacier ice, with an aim of deriving insights into its flow and fracture through satellite remote sensing methods. Glaciers deform through the driving force of their own weight and display dramatic responses to both external forcing, such as changes in climate, and internal forcing like variations in stress. Here,

Eurasian Arctic Ice Shelves and Tidewater Ice Margins
2017Despite the presence of about 4000 km of marine-terminating glaciers and ice caps in the Eurasian Arctic, there are few floating ice shelves. Neither are there extensive areas of multi-year shorefast sea ice which might thicken into composite ice shelves themselves.

When will the Antarctic ice shelves not be viable anymore?
The Antarctic contribution to sea-level rise in the coming centuries remains very uncertain, due to the possible triggering of instabilities such as the Marine Ice Sheet Instability (MISI) and Marine Ice Cliff Instability (MICI). These instabilities are mainly linked to the evolution of the floating ice shelves, which usually buttress the ice flow fromClara Burgard +5 more

The Ellesmere Ice Shelves, Nunavut, Canada
2017The Ellesmere ice shelves are located on the northernmost edge of Canada, the northwest coast of Ellesmere Island, facing the perennial pack ice of the Arctic Ocean. They are the only ice shelves in Canada and the most extensive in the entire Arctic. The special nature of the Ellesmere ice shelves extends to the essential role that sea ice has played ...
