Outline of Research at the Start

高生物生産力と水産資源を誇る西部北太平洋亜寒帯域は、現在、深刻な海洋酸性化が進行している。特に、数年以内に、冬季二酸化炭素の大気放出の停止により、海洋酸性化が加速し、炭酸カルシウムが溶解する未飽和状態になることが予想され、海洋生物への影響も必至である。そのため、海洋観測を実施し、酸性化の加速と生物への影響を明らかにする。加えて、将来の社会発展予測シナリオに基づいた酸性化進行と生物影響の予測を行う。

Outline of Final Research Achievements

We observed and used biogeochemical data for the past 25 years (1999-2023) to investigate ocean acidification and changes in biological production at site K2 in the western subarctic region of the North Pacific Ocean. As a result of the oceanic uptake of anthropogenic CO2 from the atmosphere, the deseasonalized annual mean surface mixed-layer pH decreased and is consistent with those calculated for winter. Under these acidification conditions, no significant trends were observed in the annual mean or winter nutrient contents or total alkalinity. However, the decadal trends in nutrient concentrations show a significant increase in May and decrease in July. A significant decreasing trend in satellite-derived photosynthetically active radiation was observed in May, which may be linked to reduced biological production during that month. This decrease may be offset by increased production in summer that is likely due to a shift in the timing of the diatom bloom.

Academic Significance and Societal Importance of the Research Achievements

西部北太平洋亜寒帯域は、外洋域で最も早く炭酸カルシウム飽和度が未飽和になると予測されている。このような海域で、従来の船舶観測に加え、係留系を用いた時系列観測を実施し、酸性化進行と冬季酸性化の加速を検出し、生物影響評価したことは、今後起こり得る他の海域への応用する上で非常に学術的意義がある。加えて、以上の結果をもとに、食物網の底辺を支える低次生物のプランクトンの大きな変化がなかったことにより、サケ、サンマなどに代表される我が国の豊かな水産資源を支える西部亜寒帯循環の生態系や水産資源まで大きな影響が及ばない可能性を示したことは社会的的意義がある。
