New marine-geophysical data were analyzed to investigate the sedimentary processes operating on the continental slope north of Nordaustlandet, Svalbard. Kvitøya Trough terminates in a trough-mouth fan (TMF) on the slope, whereas Albertini Trough incises the shelf edge and a TMF is notably absent. Instead, the continental slope beyond Albertini Trough is dominated by thick, acoustically stratified...
Ice stream configuration and sedimentary processes in Albertini Trough, north of Nordaustlandet, were studied using multibeam bathymetry, seismic reflection and sub-bottom profiles together with sediment gravity cores. Progradational sediment packages in the outer Albertini Trough suggest that streaming ice reached the shelf edge multiple times during the last c. 2.6 Ma. S–N-oriented glacial lineations...
Observations of subglacial landforms yielding the configuration and dynamics of former ice‐flows have for the first time been made in Rijpfjorden and Duvefjorden, Nordaustlandet, Svalbard, using sub‐bottom acoustic, swath‐bathymetric data and sediment cores. Five acoustic‐stratigraphic units were distinguished suggesting the presence of a complete glacial–postglacial succession in the central fjord...
