Abstract

We compared sea ice concentration(SIC) and sea ice extent(SIE) using EUMETSAT Ocean and Sea Ice Satellite Application Facilities(OSI SAF) and NASA Team(NT) sea ice algorithm in the Arctic during 1980-2010 to investigate the difference between sea ice data applied different algorithms. SIC and SIE of the two data showed different consistency by season and by sea area. Seasonally, SIC of OSI SAF was 0.85 % overall, 0.48 % in spring, 0.97 % in summer, 1.38 % in autumn and 0.66 % in winter higher than NT SIC. By sea area, OSI SAF SIC was 2.7 %, SIE was $198,000km^2$ higher than NT in Arctic Ocean, but in Lincoln Sea, OSI SAF SIC was 2.3 %, SIE was $20,000km^2$ lower than NT.

본 연구에서는 산출 방법에 따른 해빙 자료 간의 차이를 조사하기 위하여 1980-2010년 북극 지역의 EUMETSAT OSI SAF, NASA Team(NT)의 해빙 농도와 해빙 면적의 차이를 비교하였다. 그 결과 두 자료의 해빙 농도와 해빙 면적이 계절별, 해역별로 다른 일관성을 보였다. 계절별로는 OSI SAF의 해빙 농도가 전체적으로 0.85 %, 봄 0.48 %, 여름 0.97 %, 가을 1.38 %, 겨울 0.66 % 높게 나타났다. 해역별로는 북극해에서 OSI SAF의 해빙 농도가 2.7 %, 해빙 면적이 19.8만 $km^2$ 높았으나 링컨해 일부에서는 해빙 농도가 2.3 %, 해빙 면적이 2만 $km^2$ 낮게 나타났다.
