The identification of features due to former permafrost in the North Sea

Analysis of offshore data at scales varing from macroscopic to kilometric suggest the former presence of permafrost in the North Sea. However due to the nature of marine data, the techniques used in recognizing features due to former permafrost differ from that used on land. The evidence can also occur in forms unique to the marine field. Awareness of the former existence of permafrost in the North Sea will aid geological assessment of offshore site investigations.
