Outline of Final Research Achievements

The impact of the extinction of marine organisms at the end of the Cretaceous was greater for coccolithophytes and smaller for diatoms, which is more in harmony with the "ocean acidification by sulfuric acid rain" theory than the "photosynthesis inhibition by impact winter" theory. First, we tested the addition of sulfuric acid to corals (early stage polyps of Acropora spp.) and foraminifera (reef dwelling benthic species), and found that the area of early stage coral polyps tended to decrease as the amount of sulfuric acid added increased. Next, we prepared highly alkaline seawater that mimicked the composition of seawater during the Cretaceous period and tested the growth of early coral polyps. The Cretaceous seawater showed a calcification rate similar to that of present-day seawater with similar carbonate saturation.

Academic Significance and Societal Importance of the Research Achievements

本研究課題による取り組みは、生物絶滅現象の新しい研究手段としての生物飼育実験法を提唱するものである。また、今回の予察的な結果は、海水の炭酸飽和度が石灰化に重要なパラメータであることを確認するとともに、将来の地球温暖化の緩和を目指して検討が進められている海洋ネガティブエミッション・海洋アルカリ増進技術の試みに関係した示唆にも富む。
