Research Abstract

Some new methods for measuring carbon, nitrogen and phosphorus in seawater were developed and applied to in situ observations in the ocean. Consequently, the detailed knowledge on biogeochemical cycles in surface ocean was obtained. In particular, by greatly modifying the conventional methods for nutrients and organic matter, novel images of biogeochemical cycles in surface ocean were successfully brought.
