AB - The purpose of this study is to assess spatiotemporal variation of coastal water qualityaccording to time and location changes. For this we developed numerical marine trophic indexbase on four water quality components (chlorophyll, suspended solids, dissolved inorganicnitrogen and phosphorus) and applied this index to the water quality data measured in thekorean coastal zone for the 7-years period from 1997 to 2003. Water quality data are obtainedonly at selected sites even though they are potentially available at any location. Therefore, inorder to estimate spatial variation of coastal water quality, it is necessary to estimate theunknown values at unsampled locations based on observation data. In this study, we used IDW(Inverse Distance Weighted) method to predict water quality components at unmeasuredlocations and applied marine trophic index to predicted values obtained by IDW interpolation.The results of this study indicate that marine trophic index and spatial interpolation are usefulfor understanding spatiotemporal characteristics of coastal water quality.
