Abstract

Gyeonggi Bay, South Korea is characterized with large tidal range about 8 meters, inflow of Han River, mud and sand mixed sediment environment, which make coastal environmental parameters vary rapidly with time and space, The monitoring of the detailed 3-D features of rapidly varying environmental parameters is a challenge using modern technologies of in situ. un-manned monitoring of vertical profiles, Geo-stationary satellite remote sensing and 3-D numerical models. Korea Ocean Development and Research Institute (KORDI) had developed an Intelligent Buoy System (INBUS) that automatically measures the vertical profiles of more than 10 parameters including temperature, salinity, suspended sediment concentration, Chlorophyll etc. every half an hour. The surface layer data of this INBUS System are used in the calibration of the satellite remote sensing data from high spatial resolution (500 x 500 m), time interval (8 times per day) Korean Communication, Ocean and Meteorological Satellite (COMS) which was launched with first Geo-stationary Ocean Color Image sensor (GOCI) in June 2010. Combination of the in situ. data from INBUS system with Geo-stationary Ocean Color Image Sensor satellite remote sensing allows us to produce accurate mapping of 2-D surface data set to cover all the area of Gyeonggi Bay.Details of modern technologies in producing rapidly varying 3-D coastal environmental p of the detailed 3-D features of rapidly varying environmental parameters is a challenge using modern technologies of in situ. un-manned monitoring of vertical profiles, Geo-stationary satellite remote sensing and 3-D numerical models.
