Tidewater glaciers on the east coast of Svalbard were examined for surface elevation changes and retreat rate. An archival digital model (DEM) from 1970 (generated aerial images by Norwegian Polar Institute) in combination with recent ArcticDEM used to compare eleven glaciers. This approach was complemented a rate estimation based analysis Landsat Sentinel-2 images. In total, four 11 tidewater became land-based due their termini. The remaining retreated at an average annual 48 m year−1,...
Glacier-fed hydrological systems in high latitude regions experience seasonal variation meltwater runoff. The peak runoff usually coincides with the highest air temperatures which drive production. This process is often accompanied by release of sediments from within glacier system that are transported and suspended concentrations as they reach proglacial realm. Sediment-laden later to marine environment expressed on surface fjords coastal waters sediment plumes. Direct monitoring these...
