SUBMARINE EVIDENCE OF THE LATE WEICHSELIAN MAXIMUM EXTENT AND THE LITTLE ICE AGE (LIA) GLACIER LIMITS IN THE ST. JONSFJORDEN REGION (SVALBARD)
The paper presents the results of bathymetric mapping of selected tidewater glaciers in the St. Jonsfjorden (Svalbard) between 2004 and 2007. We also used the bathymetric data collected by the Norwegian Hydrographic Service (NHS) as well as the shaded relief images based on them. The most clearly vi...
