Submarine gullies and an axial channel in glacier-influenced Courtauld Fjord, East Greenland
Submarine gullies have been observed widely in swath-bathymetric imagery of the shelf edge and upper slope on high-latitude margins (e.g. Noormets et al. 2009; Gales et al. 2013), but less frequently in glacier-influenced fjord settings. Gullies vary in distribution, morphology and dimensions depend...
