Multibeam Data Acquisition Action Group

A detailed post-LGM chronology of the Antarctic Ice Sheet (AIS) retreat is a necessary element of assessing the Antarctic Ice Sheet’s future stability. Multibeam bathymetry data have become increasingly valuable for identifying essential elements for establishing the ice sheet retreat history including paleo ice streams, imaging detailed glacial morphological features and their configuration on the continental shelf.

As more and more SCAR member countries deploy and use multibeam systems there is an increasing need to identify best acquisition practices as well as gaps in current data coverage to obtain critical information for the reconstruction of paleo ice flow in Antarctica.

This action group is preparing a document that will provide an overview of existing multibeam systems deployed in polar regions and current usage practices. Based on past experiences this action group will provide recommendations for usage and survey strategies that are likely to provide the best outcome with respect of reconstructing past ice flow.
