영문 초록

This study was carried out the characteristics of the seasonal fluctuation of water quality and sediment environment from November to December, 2000 around Noryeog-do, located in the southwest part of korea. In the survey of seawater quality, suspended solid(SS) was shown in the range of 10.29~45.00 mg/L and was the highest value in bottom layer in November. Dissolved oxygen (DO) and chemical oxygen demand (COD) concentrations were in the range of 8.14~10.04 mg/L, 0.12~4.53 mg/L, respectively. DO concentration showed a little of fluctuation range at layer of each time of survey, but COD concentration appeared the highest value at the surface layer in December. Dissolved inorganic nitrogen (DIN) showed more highly concentration in November than December, and it showed more highly mean value of 1.29 ㎍-at./L at the surface layer in November. Dissolved inorganic nitrogen (DIP) showed a little of fluctuation range at each layer of investigated season. N/P ratios were lower than 15 of Red field ratio in the whole area with the range of 1.45~19.18. It means that nitrogen is more controlling constituent than phosphorous in the growth of phytoplankton. In the survey of sediment environment, ignition loss (IL), chemical oxygen demand (COD), and acid volatile sulfide (AVS) are in the range of 4.63~7.62%, 8.88~ 41.47mg O2/g-dry and 0.04~3.94mg S/g-dry, respectively.
