We study marine and environmental biogeochemistry including (1) fluxes of chemical species (nutrients, organic matter, and trace elements) through the atmosphere, groundwater, and river to the ocean, and (2) transport, cycling, and sedimentation of chemical species in the ocean. We take advantages of various radionuclides (U-Th series, artificial, and cosmogenic nuclides) for tracing such environmental processes. Through these process studies, we understand ecosystem responses to the change in nutrients and organic matter, health risks by heavy metals and radionuclides, and climate changes associated with carbon cycle processes.
