Research |
I am a paleoceanographer/marine geologist who studies
the history and causes of global climate change in the Earth's past.
仠Paleoceanographic change and material cycle involving the present
丂and past oceans based on stable isotopes in foraminifera
丂and organic geochemical tracers.
仠Variations of the Kuroshio pass and intensity during the Late Quaternary.
仠Late Quaternary cliamte change in the Soutehrn Ocean and Antarctica
仠Development and application of organic geochemical and stable
丂isotopic techniques in paleoclimatology.
仠Culturing planktonic foraminiferal geochemistry for paleothermometer.
仠Carbon geochemistry of Archean hydrothermal sequence
丂in the Pilbala,terrane, Western Austlaria. |
