태풍의 이동경로에 따른 해양환경변화관측을 위한 해색 자료 분석

Abstract

When the typhoons are passing over the ocean, the ocean environment has both physical and biological impacts on the East, South sea and Yellow sea of Korea. As a result of typhoon path, vertical mixing and upwelling injured colder subsurface water, and leaded to phytoplankton blooming along the typhoons. The ocean environment before and after a typhoon played an important role in the biological effect of sea 2012년 11월 23일 접수 Received on November 23, 2012 / 2013년 2월 22일 수정 Revised on February 22, 2013 / 2013년 3월 15일 심사완료 Accepted on March 15, 2013 1 남서울대학교 지리정보공학과 Dept. of Geoinformatics Engineering, Namseoul University ※ Corresponding Author E-mail : jjc1017@gmail.com Analysis of Ocean Color Data for Observation on the Ocean Environment Change Caused by Typhoon Path 60 surface. Although the magnitude of sea surface temperature (SST) gets cooler because of typhoon path, other physical and biophysical responses are quite different such as chlorophyll, K490 and SST. The purpose of this study is to compare with the typhoon path that influenced the Korean Peninsula and ocean environment parameters which were observed by ocean color remotely-sensed data. The MODIS data were used to assess the parameters of ocean environments such as K490 and chlorophyll data from 2002 to 2005. Mean chlorophyll from MODIS data increased by about 1–4% in the East sea after the typhoon. Mean concentration of MODIS chlorophyll in the post–typhoon period increased along the typhoon passage. However, Jeju coastal area has different patterns from those of the East sea.
