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