Using a new temperature recording instrument recently developed at the Woods Hole Oceanographic Institution, downhole temperature measurements were made at five sites during Deep Sea Drilling Project Leg 86. The instrument, which can be installed in the shoe of the hydraulic piston corer, allows measurements of sediment temperature to be made simultaneously with the collection of sediment cores. A numerical procedure was applied to correct the temperature disturbance caused by the corer's friction with the sediment. Detailed temperature profiles constructed from the data were combined with the measurement of thermal conductivity to calculate heat flow. Heat flow values were generally low at all sites of Leg 86, consistent with the age of the lithosphere (〉100 m.y.) in the Northwestern Pacific Basin.
