Sea level & glacial oscillations across the Antarctic Peninsula - Dr Alex Simms

The relative sea-level (RSL) signal recorded in raised beaches across the Antarctic Peninsula is thought to reflect the retreat of the Antarctic Ice Sheet since the Last Glacial Maximum, 20,000 years ago.

However, evidence for glacial oscillations throughout the last 10,000 years suggests that its glacial history may be more complicated than initially thought. How much did these glacial oscillations 'contaminate' the RSL signal recorded in raised beaches? Can that contamination tell us anything about these glacial oscillations?

In this talk, Dr Simms reviews the evidence for glacial oscillations as well as the solid-Earth response to these. He then presents evidence in the raised beaches of the Antarctic Peninsula for both increased rates of RSL fall and potential periods of RSL rise throughout the Late Holocene.

This event has been organised by the West of England and South Wales regional committee.
