Research Abstract |
Primary productivity is very high in the western subarctic Pacific (WSP), most likely because of terrigenous input including nutrients and iron. To reveal the origin and transport processes of the iron, stable isotopes of iron were used in this study. Results of the isotope ratios are summarized as follows: Most of dissolved iron from the Amur River chemically precipitates and deposits in the estuary, the deposited particulate iron is resuspended and flows out to the Okhotsk Sea intermediate water, and it is transported southward along the east coast of Sakhalin Island and partly flows out into the WSP.
