IceBridge BedMachine Greenland, Version 5
Data set id:
IDBMG4
DOI: 10.5067/GMEVBWFLWA7X
This is the most recent version of these data.
Version Summary
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

Overview

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.
