Research Abstract

This group of university researchers has engaged in developing numerical simulation program of predicting oceanophysical effects of a huge floating offshore structure (HFOS) to the marine environment of its surrounding sea water. The main aim of the present research project is to modify the above-stated simulation program so that not only oceanophysical effects but also biological and chemical effects of an HFOS might be evaluated simultaneously ; in addition to the sea water movement, water temperature and salinity, chlorophyll-a and dissolved oxygen (DO) in the sea water are predicted by numerical simulation, and compared with observation data measured in the close vicinity of Mega-Float structure moored off Oppama in Tokyo Bay.
Some conclusion obtained in the present study are as follows :
(1) Time-variation of predicted DO agrees fairly well with that of observed DO quantitatively.
(2) To the contrary, the degree of agreement of predicted chlorophyll-a concentration with observed one is unsatisfactory. The modeling of chlorophyll-a concentration needs remarkable improvement.
(3) In order to improve prediction accuracy of chlorophyll-a, additional measurement of nutritive salts such as nitrogen and phosphorus should be carried out, and agreement of nutritive salts between prediction and observation must be examined.
