POLAR2018: Ice sheets, ice shelves and proximal processes in past, present, and future climates
Please consider submitting an abstract to the session on "Ice sheets, ice shelves and proximal processes in past, present and future climates" to be convened at the POLAR2018 SCAR/IASC Conference in Davos, Switzerland. The conference as a whole spans 15th-26th June 2018, but this session will be part of the Open Science Conference which will run during the week 19th-23rd June 2018.
Please note that the abstract deadline is 1st November 2017.
Ice sheets terminating in marine environments and/or grounded below sea level are dynamic and sensitive portions of the cryosphere, especially vulnerable to change. They are also one of the largest uncertainties in understanding the fate of ice sheets under predicted atmospheric and oceanic warming. The exposed beds of palaeo-marine ice sheets offer a rich means of studying ice dynamics over large areas and long timescales, using the geological record to provide vital insight into the processes and feedbacks that regulate marine-based ice sheet retreat.
Over the past two decades, ice shelves have thinned considerably along the Amundsen coast in West Antarctica, and partly destabilized in the Antarctic Peninsula. Destabilization of ice shelves is manifested by basal thinning through inflow of warm ocean waters, by hydrofracturing of surface melt water driven by regionally warming winds, by ice cliff failure at the ice shelf front, or by a combination of these three processes.
Here we invite contributions that aim to give insight in past, present and future ice shelf changes and their drivers across all of the atmosphere, ice, ocean, and terrestrial subglacial disciplines. Studies presenting observations, from palaeo or sub-recent in situ or remote sensing data, and models, both theoretical and numerical, are encouraged to apply, especially those that combine observations and models.
The conveners look forward to reading about your work.

The Autumn mourns her rip'ning corn
By early Winter's ravage torn;
Across her placid, azure sky,
She sees the scowling tempest fly
(RB, 1786 ... Farewell to the Banks of Ayr)
