Study uses high resolution topographic datasets to study micro-meso scale features of both offshore and onshore landscapes in one of the remote locations of Greenland

Pre-glacial erosion processes exert a significant influence on the present landforms

Both areas show similar areally scoured landscapes but show spatial variability in the distribution of glacial features — most probably because of varying lithology

The offshore study area was an ice stream onset region for the paleo ice stream that created the Melville Bay trough.
