Thermal environment of the tidal flat is one of the major parts of the contaminated geo-environmentof the Ariake Sea. The activities of marine ecosystem in tidal flats depend strongly on thethermal environment. In order to get a clear idea about the thermal environment of the tidal flats of theAriake Sea, two study areas, Iida and Higashiyoka tidal flats were selected. By installing five nos. ofthermocouple (Tokyo Sokki co., Model no.: N004853) at different specified depths ( 0.10 m,0.20m,0.50 m,1.0 m and 2.0 m) connected with data logger (TDS-530) were used to observe diurnalvariation of temperature during the 1 st April to 8 th April, 2006 at Higashiyoka tidal flat. The measuredtemperature was stored automatically at 1 h interval in the data logger. To observe seasonal variation oftemperature in different depths , temperature was measured by inserting the thermocouple at 0.10 mdepths interval in the last week of every month at both study areas in the Ariake sea tidal flat. Thediurnal temperature variation was more visible near the surface (0.10 m and 0.20 m) indicating theinfluence of solar radiation in that portion, however in the deeper region (1.0 m and 2.0 m depth) thetemperature was dominated by thermal properties of the mud. From seasonal variation of temperature itwas seen that during spring and summer heat was transferred from subsurface to the deeper area butduring winter and autumn opposite phenomenon was observed. A correlation is proposed to get thetemperature profile in the tidal flat in different seasons. |
