Everyone who lives near the sea wants to know what global warming will do to the ice sheets and if this will affect the dryness of their front rooms. However, scientific prediction is a tricky business and requires you to know a lot about how the ice sheets, ocean and climate behave and interact. One way to find out this information is to study past ice masses. By looking at the landforms left behind by palaeo ice sheets, we can reconstruct their geometry and compare with ice core records to study how they responded to changes in the climate. My work will improve the production of the 3D ice margin reconstructions on which much of our understanding of modern and palaeo ice mass behaviour relies.
At present there are several areas of uncertainty in the process of palaeoglacial reconstruction, especially in areas of rugged terrain where many modern glaciers and ice sheets are located. I will work on both modern and palaeo ice masses to develop a methodology to produce more accurate reconstructions of palaeo ice margins from glacial geomorphology and underlying topography. Critically, I aim to determine a method for quantifying the confidence of 3D ice margin reconstructions. This will improve their testability and promote the use of quantitative methods in the comparison of ice margin reconstructions with numerical ice sheet models. Therefore, my work will contribute to reducing uncertainty in palaeo ice mass reconstruction and to improving our knowledge of the behaviour of past and present ice masses.
