Reconstructing the pattern and style of deglaciation in Professor Glacier, King George Island, South Shetlands, Antarctica

This paper presents the application of glacial geomorphological maps for reconstructing the pattern and style of deglaciation of Professor Glacier, located at King George, South Shetland Islands, Antarctica. The geomorphological maps were compiled from aerial photographs and multitemporal satellite...
