Study on Monitoring System of Coastal Environment (3rd Report)

—Monitoring of Phytoplankton Concentration by Assimilation—

Abstract

In order to manage and assess coastal environment, developing of a monitoring system is becoming important and urgent theme recently. The authors emphasize that the monitoring system should include not only measuring and watching but also short-term prediction and assessment of environmental factors. The measuring techniques by using images of the sea surface have been developed and a new assimilation technique has also been proposed for Yura area in the previous paper. This paper deals with the monitoring method of phytoplankton by the assimilation, in which a simple mathematical model and the measured data are used effectively. The present method is explained in general form and examined in detail. The effectiveness of the method is shown by the field measurement at Yura.
