The relationship between turbidity and temperature-salinity relation in the estuary is not well known, although the turbidity has been used as an index of water masses in the field of optics in the ocean science from space by the remote sensing.<br> In this paper, in order to clarify whether the turbidity can be used as an index of water masses in the estuary or not, distribution of the turbidity change by standing water samples for one minute at 400 nm wave length in an absorption cell was compared with the pattern of the area by T-S diagrams in a half tidal period, at all stations of 56 fishing boats anchored in the inner area of the Ariake Sea.<br> The results obtained are as follows.<br> 1) Turbidity change reached a maximum after one minute from the beginning of deterurination for standing water samples. Therefore, the turbidity change after one minute was indicated as the turbidity.<br> 2) It was found that the difference of water masses in the coastal and offshore side divided by the line showing 0.001 of turbidity change is in complete agreement with the pattern of the area by T-S diagrams in a half tidal period of all stations.<br> Therefore, it can be concluded that the turbidity change could be used as an index of water masses in the estuary.
