Cryogenic features of the permafrost ice caves of Grottedal, northeast Greenland
The caves of Grottedal, Kronprins Christian Land, northeast Greenland, are found within the continuous Arctic permafrost zone. The caves contain several cryogenic features, including minerals and ice deposits. Convection loops within the air of the caves appear to create a sublimation horizon, above...
