열적외선 위성자료를 이요한 연안해역에서의 해수면온도 모니터링

Abstract

The Saemangeum Reclamation Project was launched as a national project in 1991 to reclaim a large coastal area. The dyke construction has abruptly changed not only the estuarine tidal system inside the dyke, but also the coastal marine environment outside the dyke. In this study, we investigated the spatial change of SST distribution using satellite data. The seasonal change in detailed spatial distribution of SST was measured using Landsat-5/7, however, the estimation of change during the Saemangeum dyke's construction was hard to figure out owing to the various environmental conditions that each landsat image has. Monthly averaged SST has been analyzed for a complement of Landsat's temporal resolution. At the inside of the dyke, the change of SST from summer to winter was large the relatively high temperature in summer. So, the seasonal variation of SST was shown remarkably. At the outside of the dyke, the change of SST wasn’t large, In this study, multi-sensor thermal remote sensing is an efficient tool for monitoring the temporal and spatial distribution of SST in coastal sea. Future, we will monitor the change of SST using various satellite data in the costal sea.
