Abstract	Abstract − In order to understand the circulation of nutrient between muddy tidal flat and the surroundingcoastal area, tidal time-scale variations in nutrient concentrations were seasonally investigated at the entranceof Hampyeong Bay. The results show that the temperature was higher in ebb tide and lower in flood tide duringthe summer, but it was lower in ebb tide and higher in flood tide during the autumn/winter. The salinity washigher in flood tide and lower in ebb tide during the summer/winter because of the inflow of external sea waterresulting from the increase in the tide level. By contrast, the salinity was lower in flood tide and higher in ebbtide during the autumn. Salinity difference was lower than 0.3 psu between flood tide and ebb tide during surveyperiod. Meanwhile, all nutrient concentrations observed in Hampyeong Bay was lower in flood tide and higherin ebb tide during the summer, and by contrast, it was higher in flood tide and lower in ebb tide during the win-ter. Characteristically, no clear variation of concentrations was found depending on the tide level during theautumn. This tidal variations imply that the muddy tidal flat of Hampyeong Bay supplies nutrients to the sea-water in summer and removes nutrient from the seawater in winter. During tidal cycle, seasonal variation ofnutrient concentration in seawater is considered as the result of complex interactions between the mud flat andexternal sea water.
