| Research Abstract |
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.
