Short biography:
Research interests are mainly ice sheet dynamics and hydrology, and more recently, Southern Ocean paleoclimate.
Undergrad: Geophysics, University of East Anglia (UK).
PhD: Glaciology, Aberystwyth University (UK).
I’m currently a postdoc with the EU-funded “Tipping points in Antarctic climate components (TiPACCs)” project. The main focus of TiPACCs is the stability of the Antarctic Ice Sheet and ice/ocean interactions in the near future. However, my part within the project is to investigate ice sheet stability over longer periods, particularly during the last interglacial. I’ve previously worked in alpine glaciology (based in Aberystwyth) and Greenland Ice Sheet hydrology (Bristol, UK). I then spent some years as an arborist in Scotland and New Zealand, before coming to Bergen and joining TiPACCs.
Abstract:
Images of collapsing ice shelves in Antarctica capture our attention and help increase public awareness of ice sheet vulnerability to climate change. However, future evolution of the Antarctic Ice Sheet is likely to also depend on processes occurring out of sight, beneath hundreds of metres of ice. This includes basal melting beneath ice shelves, feedbacks between ice motion and sediment deformation, and isostatic adjustment to changing ice load. In this talk I will summarise work we are doing related to ice shelf melt and ice dynamics over glacial-interglacial time scales, and explain why these processes introduce some large uncertainties in the ice sheet’s contribution to sea-level changes.
