Abstract
This study investigates the temporal and spatial variations in the characteristics of bottom sediments around the Tama River mouth. Sediment samples were taken from 28 points every 3 months between May 2007 and October 2009, including the Tama River mouth area and an offshore site with a water depth of about 24 m. The collected sediment cores were sliced into four layers by depth (0-1 cm, 1-2 cm, 2-4 cm, and 4-10 cm) and the samples were analyzed, which included determining grain size distribution, water content, ignition loss, and oxidation-reduction potential. The data showed that the sediments at different monitoring sites responded to the impact of the typhoonrelated flood that struck the Tama River in early September of 2007 quite differently. Drastic changes in water and organic content were observed, especially at the deep offshore site, due to the typhoon.
