Multibeam (swath) bathymetry, high-resolution two-dimensional seismic (chirp) profiles and four gravity cores have been analyzed to reconstruct the Late Weichselian and Holocene sedimentary environments and glacier dynamics in St Jonsfjorden, central western Spitsbergen (Svalbard). The sediment cores comprise stratified glacimarine sediments with varying amounts of ice rafted debris. Three cores ...
