본 연구에서는 1993년 야간 가시밴드 위성원격탐사 DMSP/OLS 자료를 이용하여 동해 전해역 야간 어선의 시공간적 변화를 GIS(Geographic Information System)에 적용하여 살펴보았다. 야간 어선의 월별 및 계절분포를 조사하기 위해 연구 영역을 위도 30$^{\circ}$ $N-44^{\circ} N, 경도 124^{\circ} E-142^{\circ}$ E을 선택했다. 어선의 시공간적 분포 분석에 이용한 GIS 소프트웨어는 ArcView 3.2로서 그 확장기능 중에서 Image Analyst를 이용하였다. 야간 가시밴드 Operational Linescan System(OLS) 영상은 야간 어선의 시공간적 분포에 대한 유용한 정보를 제공한다. 분석된 결과를 보면, 야간 어선이 밀집된 해역은 대마도와 대한해협주변, 한국 동해안 연안지역, 일본 혼슈열도 연안지역, 대화퇴 주변해역이었다

Monthly distributions of fishing boats at night in the East Sea are described, using defense meteorological satellite program (DMSP)/operational linescan system (OLS) images and common squid (Todarodes pacificus) catches data. We also estimated temperature in 50m, which is main catch depth of the squid, by MCSST (multi-channel sea surface temperature). We examined DMSP/OLS, MCSST and other observation data from 1993 to 2000. We assumed that squid were caught in areas where fishing boats were located. Fishing boats at night appeared only near the Korea/Tsushima Strait from January to March. Fishing boats moved to the northward from April to Jun, distribution of fishing boats in spring appeared greater than those in winter. In summer (July-September), center of fishing grounds was formed near the Uleung Island in the south east coast of Korea. The north-south distribution range of fishing boats in October appeared to be greater than that in other months. In particular, we estimated main season of squid catches based on distribution range reflecting the number of fishing boats of north-south and east-west directions from September to December. Relationship between satellite estimate SST and in situ SST showed high correlation (0.91). The correlation between the SST and 50m depth temperature, estimated based on the satellite SST, was relatively high in February, April and October.

We examined the relationship between the 50m temperature estimated by remote sensing sea surface temperature (SST) and fishing ground (squid fishing ground) detected by nighttime visible channel defense meteorological satellite program (DMSP) I operational linescan system (OLS) images in the East/Japan Sea during 1993-2000. The results are as follows: The numbers of nighttime fishing boat were distributed the highest in October, and the lowest in April during this study. A nighttime fishing grounds have concentrated in the East Korea Warm Current region, coastal regions of Honshu Island, and Polar front region. Fishing grounds have distributed $11-18^{\circ}C$ of estimated 50m temperature from the satellite data. Relationship between estimated 50m temperature and the distributed fisheries boats showed that the north boundaries of fishing grounds have distributed the temperature of below $12^{\circ}C$ from 1996 to 2000 and that of $13-15^{\circ}C$ during 1993-1995 and 1997-1999. Stable fishing grounds appeared near the Korea/Tsushima Strait from January to March. The center of fishing grounds in spring (April-Jun) have moved to the northward than that in winter, and variations appeared largely in winter. In summer (July-September), center of fishing grounds have formed near the Uleung Island in the south east coast of Korea, and in autumn maximum fishing ground appeared in October, the fishing ground southward from November.

Spatio-temporal distributions of nighttime fishing fleets were described with the aid of geographic information system (GIS) technology in the East Sea, using daily mean composite images of the Defense Meteorological Satellite Program (DMSP) /Operational Linescan System (OLS) in 1993 and 1994. We selected a study area from 30$^{\circ}$N to 44$^{\circ}$N in latitude and from 124$^{\circ}$E to 142$^{\circ}$E in longitude in order to describe the monthly and seasonal changes of nighttime fishing fleets. The OLS images of nighttime visible band provide useful information about the spatio-temporal distribution of the fishing fleets. Density areas of nighttime fishing fleets were around Tsushima/Korea Strait. the east coast of the Korea Peninsula, the coast of Honshu, and around Yamato Bank.

본 연구는 DMSP 위성의 OLS 센서에서 촬영된 Stable Lights 영상자료로부터 랴오닝성과 단둥시의 빛합계 지수를 도출한 후 이 지표와 경제 수준 간 관계를 분석하였다. 랴오닝성의 빛합계 지수는 다른 성급 지역의 평균보다 높은 수준이었고, 지난 20여 년 동안 지속적인 증가 추세를 보였다. 실질 성장률과 1인당 평균 임금 등 이 지역의 경제 수준 향상을 지시하는 경제 지표 변화를 잘 반영한다고 볼 수 있다. 그러나 단둥시의 빛합계 지수는 다른 지급시 평균보다 낮은 수준이었는데, 이는 주요 경제 지표에 기초한 이 도시의 경제적 지위와 맥을 같이하는 것으로 보인다. 이전 시기에 비해 1998~2007년 사이 대북무역이 활성화된 단둥시 시할구의 빛합계 지수의 연간 증가율이 높아졌고, 비슷한 기간 동안 북중 교역액과 북한의 대중 수출액도 증가하는 패턴을 보였다. 이 기간 동안 햇볕정책의 영향으로 남 북한 간 긴장 관계가 완화되었던 것을 비추어볼 때, 빛합계 지수는 단둥시의 지정학 및 지경학의 특성을 설명할 수 있는 공간 대안 지표로 활용될 수 있을 것으로 기대된다.
