Outline of Final Research Achievements

Oyashio is one of most highly productive ocean in the world. This is owing to the Pan-Okhotsk land-ocean linkage system that provides the Oyashio with iron, an essential micronutrient, originating in wetlands in the Amur River basin via intermediate-layer circulation in the Sea of Okhotsk. This project aimed to elucidate roles of precipitation, snow and glacier over the Kamchatka Peninsula, which transfers information of atmospheric variations to the ocean through riverine discharge. We hypothesized that the riverine discharage from the peninsula may control the Pan-Okhotsk land-ocean linkage system. We have found that (1) the total amount of discharge from the Kamchatka Peninsula is approximately 80% of that of the Amur River, and (2) freshwater from the Kamchatka Peninsula gives more impacts on salinity of the dense shelf water that drives the intermediate-layer circulation than that from the Amur River does.

Academic Significance and Societal Importance of the Research Achievements

本研究では、カムチャツカ半島からの淡水供給に注目して、親潮海域の植物プランクトン増殖に必須な鉄分輸送に対する制御メカニズムの解明を目指した。従来、オホーツク海への淡水供給といえばアムール川が注目されてきた。しかし本研究で、カムチャツカ半島からの河川流出量が全体でみるとアムール川に匹敵すること、また地理的条件から鉄分を輸送する中層循環に重要なのはむしろカムチャツカ半島河川水であることを見出した。親潮海域は世界で植物プランクトン生産が最も大きく豊かな水産資源資源を支えているのと同時に、CO2吸収も膨大である。本研究はこの高生産海域の将来予測やSDGsにつながる研究であり、社会的意義が大きい。
