OSTI ID:5950827
Estimates of heat flow and geothermal gradients were obtained for the outer continental shelf, slope, and rise of the Alaskan Beaufort Sea. Well-developed seismic bottom simulating reflectors (BSRs) in the region indicate the base of the gas hydrate stability zone. The lateral distribution and subbottom depth of BSRs from all available single and multichannel seismic lines from the region were mapped. The subbottom depths of the BSRs are principally controlled by the pressure and temperature limits of methane hydrate stability. Using models derived from other regions, estimated geothermal gradients were obtained from measured water depths, water temperatures, and BSR depths.
