I am in charge of the Geochemistry Course in Graduate School of Environmental Sciences, Hokkaido University (HP is here). Potential research topics for graduate students are as follows.

Marine sediment
　You can study climate change on various time scales (decades to hundreds of thousands of years scale). As the marine sediment core records global climate change, it is recommended for students who want to investigate the mechanism of global climate change. It is also recommended for students who are interested in ocean cruise.

Lacustrine/peat sediments
　From lake/peat sediments, you can study climate change mainly on the decade to tens of thousands years scale. Because lake/peat sediment reflects local land climate change, it is recommended for students who are interested in regional climate change. It is also recommended for students who are interested in land fieldwork.

Ice core
　From ice core, you can study climate change on the scale of ten to tens of thousands years. Information on past atmospheric environment can be obtained from ice core. It is recommended for students interested in relation between aerosol and climate. You may have opportunities to join fieldwork in Greenland, Antarctica and mountain glaciers.

Seminar
　We have the seminar once or twice a month with groups of associate professor Jun Nishioka and assistant professor Sumito Matoba of the Pan Okhotsk Sea Research Center.

Grad stundent is now wanted. If you are interested in my group, please contact me（seki at lowtem.hokudai.ac.jp.）
