Drill hole measurements of land-fast sea ice and sub-ice platelet layer thicknesses, fast ice freeboard, and snow depth in Gerlache Inlet, north Terra Nova Bay, Antarctica in November 2021
Here, we present drill hole measurements of land-fast sea ice and sub-ice platelet layer thicknesses, fast ice freeboard, and snow depth collected at 6 drill sites distributed over a 60 km^2 fast ice area in Gerlache Inlet, north Terra Nova Bay, western Ross Sea, Antarctica between 3 and 7 November...
