In order to clarify the deep ocean circulation which forms the current state of ocean and climate by transporting deep water, we conducted oceanographic observations in the North Pacific where deep water upwells and returns to south. Analyzing the oceanographic data, we clarified the variability of location, velocity, and volume transport of deep current in the lower deep layer (deeper than 3500m) which flows in the Northwest Pacific Basin proceeding northward in the Pacific Ocean, and also clarified the distribution and volume transport of deep current in the upper deep layer (2000-3500m depth) which overturns and returns to the Antarctic Ocean. Moreover, we proposed the overall picture of the Pacific Ocean circulation by integrating the results of the study.

为了弄清通过输送深水形成海洋和气候现状的深海环流，我们在北太平洋进行了深海上涌并向南回流的海洋观测。通过对海洋资料的分析，阐明了在太平洋向北流动的西北太平洋盆地深层深层（深度大于3500m）深流的位置、速度和体积输运的变异性，也阐明了上层深层（深度2000-3500m）深流的分布和体积输运。结合研究结果，提出了太平洋环流的整体图景。
