SC4 Antarctic Geological Boundary Conditions (ABC)
OBJECTIVES:
ABC will address 3 key questions:
1. What are the subglacial properties and processes relevant for past and future ice dynamics?
2. What is the role of geological controls and erosion and sedimentation on ice sheet dynamics?
3. How do glaciological, geological and geophysical records inform us about the ice sheet and landscape?
The main objectives are:
- To improve maps of modern subglacial and offshore topography, bathymetry and geology – interpreting the landscape in respect of past and present ice flow.
- Develop improved reconstructions of past topography and bathymetry
- Enhance understanding of the distribution of water at the base of the ice (links to geothermal heat flux sub-committee).
- Integrate and ‘translate’ geologic and topographic characteristics into continent-wide data products to be used in ice sheet models.
