IceBridge BedMachine Greenland, Version 5 (IDBMG4)
This is the most recent version of these data.
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
This data set contains a bed topography/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.
