Near-shore Arctic Subsea Permafrost in Transition
Models and geophysical data indicate that large areas of the Arctic shelves, as a result of their exposure during the last glacial maximum, are thought to be almost entirely underlain by subsea permafrost from the coastline down to a water depth of about 100 meters. Subsea permafrost is still poorly...
