Description
This data set contains a bed topography and bathymetry map of Greenland based on mass conservation, multi-beam data, and other techniques. It also includes surface elevation and ice thickness data, as well as an ice/ocean/land mask.
Version Description
This data set is the same as Version 4 with the following changes:
-Added bathymetry measurements from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, in front of the Northeast Greenland Ice Stream
-Added ice thickness for ice caps from Millan et al. (2022) (https://www.nature.com/articles/s41561-021-00885-z)
-Included bathymetry data from NASA's 2021 Oceans Melting Greenland (OMG) campaign
-Provided a geotiff file of bed elevation
Citation is critically important for dataset documentation and discovery. This dataset is openly shared, without restriction, in accordance with the EOSDIS Data Use and Citation Guidance.
