AGU Fall Meeting 2017: (C005) Antarctic Ice Shelves: surface and basal processes, instability and breakup

Alison Banwell
Dear Colleagues,

You are invited to submit an abstract to the 2017 Fall AGU meeting session entitled: (C005) Antarctic Ice Shelves: surface and basal processes, instability and breakup

Session ID: 24431 (https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session24431)

Conveners: Amber Leeson (University of Lancaster, UK), Ian Willis (University of Cambridge, UK), Alison Banwell University of Cambridge, UK) and Dan Goldberg (University of Edinburgh, UK).

Session Description: In Antarctica, 44% of the coastline is fringed by ice shelves extending 1.5 million km2. Ice shelves buttress flow from grounded ice into the sea, and so are an important control on ice sheet mass balance. As recent shelf loss on the Antarctic Peninsula has resulted in outlet glacier speed-up and sea level rise, understanding the processes leading to ice shelf instability and break-up is of huge societal importance. Changes in atmosphere/ocean circulation and air/water temperature are implicated in recent collapse events through their effects on surface/basal melting respectively. The precise mechanisms involved remain elusive, but it is thought that fracture mechanics may play a role. Here we seek contributions from all geoscientists investigating processes occurring above, on, within and below ice shelves through fieldwork, remote-sensing and modelling. Our aim is to improve knowledge about past and current ice shelf dynamics and stability, and elucidat
 e potential future ice shelf states.

Confirmed Invited Speakers: Bryn Hubbard (Aberystwyth University, UK) and Paul Holland (British Antarctic Survey, UK).

The AGU Fall Meeting will be held 11-15 December 2017 in New Orleans this year (https://fallmeeting.agu.org/2017/)

The abstract submission will be open on June 26 and the deadline is August 2.

We hope to see you in New Orleans!

Alison Banwell, Amber Leeson, Ian Willis and Dan Goldberg
