Characteristics of Physicochemical Factors of Inchon Dock Ecosystem, Korea

Abstract
|
|
|
Due to its lake of wave action and tide ecosystem in Inchon dock lacks in marine characteristics. Structural condition in the dock is artifically similar to that of lake.
The purpose of this study was to clarify the water quality, to provide the basic physicochemical data and to resolve the causation of algal blooming. Samples were obtained monthly from four stations in Inchon dock during January to December, 1991.
Water temperature ranged from 2.7℃ to 27.6℃ under the strong influence of air temperature. Salinity varied between 24.7‰∼30.4‰ thus being influenced by freshwater discharged from a spring. Dissolved oxygen was concentrated from 0.1∼13.92 ㎎/l and suspended soilds were 6.9∼231.0 ㎎/l. The physicochemical factors were similar to those investigated 10 years ago. However, increased concentration of nitrogenous nutrients initiated algal blooming and its process is accelerated to reach eutrophication. Algal blooming was proceeded in March and August.
