| Outline of Final Research Achievements |
For more than 20 years, standard hydrographic observations have been conducted monthly in Tokyo bay by Tokyo University of Marine Science and Technology. Since a drastic change in biogeochemical setting is anticipated because of the continuing decrease of nutrient load into the bay, we have tested updates of our monthly monitoring with introduction of several new parameters. The tested parameters include alkaline phosphatase activity, carbonate parameters, primary production and nitrogen uptake, and denitrification (anammox) activity. The incorporation of these parameters are demonstrated to be very useful in detecting the nutrient-limitation events in the bay.
