By controlling the aggregate amount of pollutant in the special coastal pollutant control sea area through setting the target water quality of the designated sea area and by setting the total amount of allowed volume of pollutant, Korea controls the inflow of pollutant into the sea area. Furthermore, Korea conducts study on the amount of waste in the ocean and collect the waste on the seabed through the project to deal with marine waste. In addition, Korea is restoring damaged, abandoned and polluted tideland to restore the function of the marine ecosystem and enhancing our understanding on the current marine environment by operating a National Marine Environment Monitoring System. Korea also has designated and have been managing 27 Marine Protected Areas and collecting and disposing of contaminated sediment in the half-closed marine areas with not enough sea water flow.
