CASP-ROSSMAP are merging
Unified interpretation of geophysical data sets collected around Antarctica
CASP-ROSSMAP will integrate the various regional stratigraphies to achieve a unified circum-Antarctic seismic stratigraphic model that in turn can be linked to available rock sample record to determine ages, lithostratigraphies and paleoenvironments. This project will also help define potential future drill sites (SHALLDRILL/ANDRILL/IODP) at key locations around the Antarctic Margin
Through unified interpretation of geophysical data sets collected around Antarctica CASP-ROSSMAP addresses basic questions relating to the behaviour of Antarctic ice sheets and the geological evolution of the Antarctic margin including:
- How extensive were past advances of Antarctic ice sheets across the margin and how did they relate to changes in the overall ice volume?
- How does the Antarctic continental crust respond to ice volume changes during glacial to interglacial cycles?
- How has the growth of the Southern Ocean affected global circulation and paleoclimate evolution?
- What feedback controls are there between tectonics, landscape and climate?
