AWI EMR radar data upstream of the northern catchment of the Nioghalvfjerdsbrae (79°North Glacier), Northeast Greenland

Here we present AWI EMR radio-echo sounding data in northeast Greenland upstream of the northern catchment of the Nioghalvfjerdsbrae (79°North Glacier; 79NG). The radar data were acquired with AWI's EMR radar system in 1998. The radar lines are located between the central ice divide and the Northeastern glacier outlet region. The radio-echo sounding data was used to decipher the regional ice-flow history of the northeastern Greenland Ice Sheet based on its internal stratigraphy by mapping folds deep below the surface that we then attribute to the deformation caused by now-extinct ice streams. Locally, this ancient ice flow regime was much more focused and reached much further inland than today's and was deactivated when the main drainage system was reconfigured and relocated southwards.
