We have been conducting monthly sea water sampling to detect particulate/dissolved mercury at three sites in Minamata Bay from 2006. After 2010, LISST-100X was applied for measurement of vertical profile of suspended solid grain size distribution. Also, highly resolved core sampling of bottom sediment at about 100 sites and deposition rate measurement were carried out. As a result, the followings were clarified: i) Correlation between SS grain size characteristics and particulate total mercury concentration was confirmed; ii) Spatial distributions for median grain size and water content of bottom sediment and deposition rate of SS were detected.
