“Revealing the Fine-Scale Dynamics of the Retreating Irish Ice Sheet”
By Dr Catherine Delaney (Manchester Metropolitan University)

Abstract:
Meltwater from glaciers and ice sheets will play an increasingly important role in sea-level rise in the coming centuries. However, the response of ice sheets and glaciers to increasing temperatures is not straightforward. This talk will examine the impact of data resolution on understanding of the retreat of the last Irish Ice Sheet. High resolution techniques indicate that the last Irish ice sheet (ca. 20,000 BP) switched between episodes of fast ice flow associated with a warm, wet ice sheet base, and a slower, partly stagnant ice margin, with parts of the margin frozen to the underlying bed. Furthermore, a micromorphological analysis can be used to reconstruct meltwater inputs and associated ice sheet dynamics on a fine-scale year-by-year basis.
