I am a PhD student working with Dr. Lauren Gregoire, Dr. Ruza Ivanovic, Prof. Alan Haywood and Dr. Julia Tindall at the University of Leeds. My project involves modelling the collapse of the North American ice sheet and evaluating its role in the abrupt cooling of the Northern Hemisphere during the 8.2kyr event.

Before starting my research project here in Leeds I've been working as a scientist and a research assistant in the Polar Oceanography and Sea Ice group at the Finnish Meteorological Institute. Projects included analyses based on ice charts, satellite data and in situ studies of the properties and distribution of sea ice.

Project outline

My research is planned to consist of the following three parts in order to evaluate the role of the ice sheet collapse and it's direct and indirect impact on the 8.2kyr event:

  • Laurentide ice sheet collapse reconstruction: State of the art marine ice sheet model (BISICLES ; Cornford et al., 2013) and the latest glaciological data from collaborator Anders Carlson will be combined to produce the most detailed reconstruction of the Laurentide ice sheet collapse around the 8.2 kyr event.
  • Climatic impact of the collapse: These reconstructed ice sheet elevation changes and meltwater routing to the ocean will be used to force the Met Office UM general circulation climate model and analyse the effects on climate.
  • Re-assessment of Climate Models’ ability to simulate the strength and duration of the 8.2 kyr event. Results from the two above parts will be used to formulate new hypotheses on the cause of the 8.2 kyr event. A standard experimental set-up for the 8.2 kyr event combining the ice sheet collapse and lake drainage will be produced for a multi-model experiment as part of the PMIP3 initiative.
