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.
