Terrestrial heat flow has been measured at 116 stations in the Japan Sea area. Except the western-most part, the whole of the Japan Sea has been covered by these measurements. Major features of heat flow in the Japan Sea are as follows: (1) The heat flow values are anomalously high throughout the area, the average value being 2.17±0.40(s.d.)×10-6cal/cm2 sec. The mean of the 1°×1° grid averages is 2.24×10-6cal/cm2 sec; (2) A weak positive correlation seems to exist between the heat flow and the water depth. Heat flow is higher in the northern deep basin, which has a typically oceanic deep basin, than in the southern part with a continental crust.
1964年に着手された日本海の地殻熱流量観測は, 1965年も引続き舞鶴海洋気象台観測船｢清風丸｣により行なわれ,測定点は,西部を除く日本海全域に渡り116点を数える.この結果, (1)地殻熱流量値は測定海域の全域に渡り異常に高く,その平均値は2.17±0.40×10-6cal/cm2sec,日本海を1°毎の網目に切つた1°×1°網による一種の荷重平均値は2.24×10-6cal/cm2に達する. (2)水深と熱流量値の間に弱い正相関があり,北部深海域で熱流量値が高く,中央部大和,北大和堆周辺で熱流量値は低い.
