AB  - Greenland’s bed topography is a primary control on ice flow, grounding line migration,calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warmAtlantic water (AW) that rapidly melts and undercuts Greenland’s marine-terminating glaciers. Here wepresent a new compilation of Greenland bed topography that assimilates seafloor bathymetry and icethickness data through a mass conservation approach. A new 150 m horizontal resolution bed topography/bathymetric map of Greenland is constructed with seamless transitions at the ice/ocean interface, yieldingmajor improvements over previous data sets, particularly in the marine-terminating sectors of northwestand southeast Greenland. Our map reveals that the total sea level potential of the Greenland ice sheetis 7.42 ± 0.05 m, which is 7 cm greater than previous estimates. Furthermore, it explains recent calvingfront response of numerous outlet glaciers and reveals new pathways by which AW can access glacierswith marine-based basins, thereby highlighting sectors of Greenland that are most vulnerable to futureoceanic forcing.
