Submarine Permafrost Map (SuPerMAP), modeled with CryoGrid 2, Circum-Arctic
This data set contains a first‐order estimate of distribution, thickness and ice-content of submarine permafrost on the Arctic shelf based on a numerical heat transfer model. Our model uses dynamic upper boundary conditions that synthesize Earth System Model air temperature, ice mass distribution an...
