Outline of Final Research Achievements

We described average sea water temperature, seasonal variability in sea water temperature, and timing of the onset of the Antarctic glaciation across the Eocene/Oligocene transition. We utilized sediments obtained by the Integrated Ocean Drilling Program, Expedition 342 at off Newfoundland, Canada. Carbon and Oxygen isotope ratios of selected planktic foraminifers recovered from the sediments of the late Eocene through early Oligocene in age were analyzed. In addition to these isotope analyses, organic molecules extracted from these sediments were also analyzed on high performance liquid chromatography to identify TEX86 temperature.

Academic Significance and Societal Importance of the Research Achievements

現在の地球は,南極およびグリーンランドに大陸氷床が存在する部分凍結状態にあるが,恐竜が陸上を闊歩していた白亜紀には大陸氷床が存在しない無氷床状態にあった.この無氷床状態から部分凍結状態への気候ジャンプは,始新世/漸新世境界に生じたことが知られている.しかし,その際の詳細な気候状態は,数値実験から予測されるのみで,データによる裏付けが不十分な状態であった.本研究では,これに対し,気候ジャンプ時における平均的海水温,海水温の季節変動幅,および氷床量の時系列変動をこれまでにない時間解像度で明らかにすることに成功した.
