This paper discusses the distribution of water masses during springtime in Shimabara Bay based on oceanographic data obtained in June 2002 and May 2003. Two low salinity water masses were found to consistently exist adjacent to Kumamoto City and Ariake-machi. The offshore water mass, which spread to 6 km from the coast of Kumamoto City in the autumn (Kinoshita, et at., 1979), also exists in the spring as found in this study. Fresh water is supplied from the sea bottom off Ariake-machi in Shimabara Peninsula. The high salinity water (33 ‰), whichflows from the East China Sea, drifts to the north through a space between the two low salinity water masses. Muddy sediments with hydrogen sulfide odor are distributed beneath the boundary between the offshore water mass and the high salinity water mass in the eastern part of Shimabara Bay.
