"Antarctic ice sheet behaviour from marine and terrestrial records"
Convenors: Richard Jones, Mike Bentley, Julia Wellner, Ruthie Halberstadt

Marine-based sectors of the Antarctic Ice Sheet are likely to contribute to sea-level rise over the coming centuries. Better understanding of the underlying processes, thresholds, magnitudes, and rates of previous ice-sheet change is essential to improve predictions of future sea-level rise and guide mitigation and adaptation. This session invites submissions on the broad range of Antarctic work being done on past ice sheet and ocean history from onshore, continental shelf, and deep-sea records.

We welcome presentations on geological and geophysical studies, including drilling programs from Antarctica and from the Southern Ocean. Marine records cover a range of short to long timescales, all of which provide key insights into ice sheet dynamics and ocean circulation change. Terrestrial studies of past glacial history using outcrop studies, geomorphology, or onshore drilling can yield complementary records of past intervals of ice sheet thickening and thinning. Studies that examine smaller-than-present configurations of the ice sheet such as during past interglacials are especially welcome, particularly where they can provide constraints on past sea-level change contributions from Antarctica.
We encourage submissions that bring together marine and terrestrial records of ice sheet behaviour or that can provide links between past Southern Ocean circulation and temperatures and ice sheet behaviour. The session is highly interdisciplinary and welcomes contributions from fields including marine geology and geophysics, sedimentology, geomorphology, paleolimnology, and paleo-oceanography as well as ice-sheet modelling.

Parallel session held at the 10th SCAR Open Science Conference (1-10 August 2022).
