| Research Abstract |
This group of university researchers has engaged in developing numerical simulation program for predicting oceanophysical effects of a very large floating offshore structure (VLFS) on marine environment of its surrounding sea water, and carrying out continuous measurement of marine environment around an existing VLFS called "Mega - Float Structure" moored in Tokyo Bay for six years. As a result, it has been clearly shown that the sessile organisms, especially mussel shell, adhered on the submerged surface of the VLFS has serious effect on the marine environment. In order to improve the accuracy of environmental impact assessment of the sessile organisms, it has been decided that numerical model for describing the grazing and respiratory activities of mussel shell should be examined in detail for various combinations of sea water temperature and salinity. For this purpose, in situ experiments of mussel shell were carried out many times at the mouth of Sumida River in Tokyo Bay. Based on these observations, key parameters of numerical models, which are deeply related to grazing and respiratory activities of mussel shell, are found to be clearly dependent on both of sea water temperature and salinity.
