BRITICE-CHRONO: Constraining the rates and style of retreat of the British-Irish Ice Sheet

Posted on 13th March 2017

Research Seminar Series – Seminar by Dr Rachel Smedley, Lecturer in Physical Geography, Keele University.

Wednesday 22nd March,

16.30-18.00, in CBB012 Best Building, University of Chester

 

BRITICE-CHRONO is a large NERC-funded consortium project. Over the last few years, we have produced the largest empirical dataset in the world constraining the retreat of a former ice mass. This dataset is now being used to test ice-sheet models and process understanding of modern-day ice sheets. My role as part of this project was to perform luminescence dating over 80 sedimentary samples constraining ice retreat, including the southernmost terrestrial maximum on the Isles of Scilly. In this talk, I will discuss the new findings of the glacial history in Britain and Ireland drawn from luminescence dating, in addition to complementary cosmogenic nuclide dating. We will then explore how this ice retreat chronology compares to existing environmental records from the past (e.g. climate, ocean temperatures, sea level) to assess what factors were driving ice retreat from the maximum throughout the last Ice Age. This will shed light on how the present-day ice sheets in Antarctica and Greenland may respond to future climate change.
