The new version of BedMachine Greenland is now available on NSIDC (https://nsidc.org/data/IDBMG4). BedMachine v3 now includes ocean bathymetry from single and multi beam data around the ice sheet, and the subglacial bed topography has been refined by incorporating additional ice thickness data. This dataset is the result of a collaborative effort amongst many international institutions including University of California Irvine, USA (NASA Cryospheric Sciences Program grant #NNX15AD55G, NSF’s ARCSS program grant #1504230, and the University of Bristol, UK (BPoG, NERC grant NE/M000869/1).

Even though BedMachine v3 is a big improvement over the previous versions, there are still some regions that remain poorly constrained, and we would be more than happy to include more bathymetry data or ice thickness data in the next release. Please contact [hidden email] if you are interested in making this dataset better by sharing your data.
As always, feedback is welcome!
