The Geobiosphere Evolution Research Team was created to investigate the evolution of the geobiosphere on a geologic time scale by analyzing ocean and land drilling cores, marine and terrestrial sediments, biological skeletons, etc. Major targets of the team are clarifying ultrahigh-resolution environmental and geobiosphere changes, the long-term history of the earth and life as recorded in ocean and land drilling cores (IODP and ICDP), and geologic constraints in the deep biosphere such as water and geochemical cycles. The team has made innovations in advanced analytical methods and ultrahigh-resolution instruments such as TATSCAN nondestructive core scanning/imaging technology, GeoMill 326 micromilling system, and optically stimulated luminescence (OSL) dating.
