The evidence for offshore permafrost is reviewed, the possible effects of permafrost on offshore operations is considered, and the need for research in offshore permafrost is examined. Increasing evidence is noted of widespread subsurface permafrost off North American Arctic coasts. This positive yet fragmentary evidence, early experience in Arctic construction projects, and the current interest in Artic offshore oil and gas development, creates a need for mapping permafrost in the Arctic environment. It is recommended that a program be immediately implemented to locate offshore permafrost; that material index properties be determined for characteristic cores and sample material obtained by drilling and bottom sampling; that models be constructed of offshore permafrost regimes including the possible variations in the thermal, chemical hydrological, and electrical properties; and that the active participation and cooperation by industry in offshore-permafrost research activities be encouraged.
