In-situ ice thickness measurements derived with ground penetrating radar from Gourdon Glacier, Antarctic Peninsula
These data report in-situ ground penetrating radar (GPR) ice thickness measurements at the outlet and the catchment area of Gourdon Glacier on James Ross Island, northern Antarctic Peninsula. Data were conducted in 2017-02-15 and 2018-02-10 with a 25 MHz GPR antenna flown as a sling load by a Bell 2...
