オホーツク海および北西北太平洋親潮域の高い海洋生物生産性を支えている物質循環のメカニズムを,海洋中層(400~800m)の循環と鉄の輸送過程に注目して,現場観測と数値モデルによる研究を行った.その結果,オホーツク海北西大陸棚起源の鉄分が,海氷の生成とともに作られるオホーツク海中層水によって移送され,千島海峡で広い深度層に分配された後,西部北太平洋に送り出されている様子が定量的に明らかとなった.

The productivity of marine organisms in the tidal zone of the North Northwest Pacific Ocean is studied. The circulation of matter and iron transport in the middle ocean (400~800m) are studied. As a result, the origin of the continental shelf in the north of the sea is divided into two parts, the formation of the sea is divided into two parts, the middle water of the sea is divided into two parts, the distribution of the depth layer of the Thousand Islands Strait is divided into three parts, and the quantitative distribution of the continental shelf in the west of the North Pacific Ocean is divided into two parts.
