Beach processes and recent sea-level changes at Tönsneset, Kongsfjorden, northwestern Spitsbergen
Beaches occur throughout the coastal regions of the world. Ridges found on beachescan be used as indicators of past climatic and oceanographic conditions. Sea-levelchanges can also be extrapolated from these landforms, if the correct conditions occur, when the facies between eolian and intertidal se...
