Ice Dynamics

I had earlier investigated the surge behaviour of sub-polar glaciers with Tavi Murray (Leeds) and Andrew Fowler (Oxford) and recently turned my attention to the Antarctic ice streams, whose variable flow exerts strong control on ice-sheet mass balance.

With Howard Conway (Seattle), I used the radar structures in Kamb Ice Stream to infer its flow speed before it stopped ~150 years ago. Ongoing work considers the general problem of deciphering the history of ice flow from englacial radar layers.
