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.

该大学的研究人员致力于开发数值模拟程序，以预测超大型浮式海洋结构物（VLFS）对其周围海水的海洋环境的影响，并对停泊在东京湾六年的称为“Mega - Float Structure”的现有VLFS周围的海洋环境进行连续测量。结果表明，附着在VLFS水下表面的固着生物，特别是贻贝壳，对海洋环境有严重的影响。为了提高固着生物环境影响评价的准确性，已决定应详细检查用于描述贻贝壳的摄食和呼吸活动的数值模型，以适应不同的海水温度和盐度组合。为此，在东京湾墨田河口多次进行了贻贝贝壳的原位实验。在此基础上，发现与贻贝摄食和呼吸活动密切相关的数值模型的关键参数明显依赖于海水温度和盐度。
