This study relating to recently identified environmental issues have been initiated. The dredging of sea bottom sand and gravel is one such issue in the Seto Inland Sea. The sea-sand and gravel in the Seto Inland Sea especially Bisan-Seto area were generated by continuous erosion at the sea bottom of the straits and channels (such as Bisan-seto) for about ten thousand years since the formation of the Seto Inland Sea. Therefore, they are resources like fossils, which cannot be recovered in a short time, and the environmental impacts of dredging and a study of the influences of turbid water generated by the dredging on sea forests have benn initiated in this study. Also, more basic studies of the physical and biogeochemical conditions of offshore sandy beds have been initiated, because little is known as yet about these areas. These studies will contribute to a more comprehensive understanding of the Seto Inland Sea.

这项研究涉及最近查明的环境问题，现已开始。在濑户内海，海底砂和砾石的疏浚就是这样一个问题。濑户内海特别是比山-濑户地区的海砂和砾石是自濑户内海形成以来近万年来，在比山-濑户等海峡和航道的海底不断侵蚀而形成的。因此，它们是化石一样的资源，在短期内是无法恢复的，而疏浚的环境影响和疏浚产生的浊水对海洋森林的影响的研究是本研究的开始。此外，由于对近海桑迪床的物理和地球化学条件知之甚少，已开始进行更多的基础研究。这些研究将有助于更全面地了解濑户内海。
