Professor Colm O'Cofaigh
I am a glacial geologist and Quaternary scientist, interested in glacial and glacially-influenced sedimentation and the reconstruction of ice sheets.
My research has evolved from an initial focus on terrestrial investigations of glacial sediments and landforms, to the use of marine geology and geophysics to reconstruct ice sheet behaviour and sedimentation. I have a particular research interest in ice sheet reconstruction and the processes and patterns of glacimarine sedimentation on polar continental margins and have worked widely in the Arctic (Greenland, Arctic Canada, Svalbard, Norwegian-Greenland Sea) and Antarctica on these topics. I also have a long-standing active research interest in the history of the last British-Irish Ice Sheet.
The underlying theme of my research is ice-sheet reconstruction from geological and geophysical evidence, and the use of modern glacial analogues to better understand the geological record.
I have been awarded the Lewis Penny Medal by the Quaternary Research Association (2005) and the Lyell Fund (2009) by the Geological Society of London in recognition of my research.
Some of my current research projects are listed below.
