Subsea permafrost either occurs in response to negative sea-bottom water temperatures, or it formed in now submerged coastal areas that were exposed previously to air temperatures below 0°C (relict permafrost). Much of the ice-bonded permafrost that has been found beneath the sea bottom has been inferred from acoustic geophysical surveys, and the term "acoustically- defined permafrost" has been used to describe such permafrost found in areas where temperature records or visual confirmation of ice bonding are not available.
