Weakened overturning and tide control the properties of Oyashio Intermediate Water, a key water mass in the North Pacific
Abstract The western subarctic Pacific exhibits major biological productivity fed by the Oyashio Current and its two source waters: Western Subarctic Water, which supplies nutrients from the subarctic Pacific, and cold Okhotsk Sea Intermediate Water (OSIW), which supplies iron from the Sea of Okhots...
