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.

这项与最近确定的环境问题有关的研究已经启动。海底沙子和砾石的挖泥就是塞多内陆海洋的一个问题。自从Seto Inland Sea的形成以来，海峡和通道的海底连续侵蚀（例如Bisan-seto）在海峡和通道的海底连续侵蚀（例如Bisan-seto），产生了seto内陆地区的海鲜和砾石。因此，它们是像化石这样的资源，无法在短时间内回收，并且疏ed的环境影响以及对疏and对海森森林产生的浑浊水的影响的研究已经在这项研究中发起。同样，已经开始对海上沙床的物理和生物地球化学条件进行更多的基础研究，因为这些区域尚未被称为这些区域。这些研究将有助于对Seto内陆海的更全面地理解。
