(1) Processing of DMSP/OLS images and data base generationWe gathered DMSP/OLS images covering Japan Sea and off Sanriku from 1994 to 1999 and generated Data base of fishing fleets distribution.(2) Processing of satellite sea surface temperature and ocean color images and data base generationWe gathered NOAA/AVHRR, ADEOS/OCTS, Orbview-2/SeaWiFS images covering Japan Sea and off Sanriku from 1994 to 1999 and generated Data base of SST and chlorophyll a.(3) Investigation of meso-scale eddies using altimeter sea surface height data.We investigated the distribution of meso-scale eddies, Kuroshio warm core rings (KWCR) and Tsugaru warm current gyres (TWCG), using TOPEX/ERS-2 sea surface height anomaly data.(4) Statistical analysis of squid fishing fleets distribution(5) Analysis of the relationship between fishing fleets distribution and SST distributionWe analyzed the position of squid fishing ground and the distanc e from SST fronts.(6) Observation of fishing fleets distribution from Mt. Hakodate using digital cameraWe developed a methodology to analyze from oblique photograph to vertical photograph and could count the number of fishing fleets in a pixel of OLS images.(7) Analysis of migration routes of Pacific sauryThe coalescence of KWCR-93A and TWCG in 1995 and 1998 cut off the intrusion of the first branch of Oyashio as one of the migration routes of Pacific saury. Fishing grounds moved to offshore and it indicated the coalescence was important phenomena changing the migration routes.

(1)DMSP/OLS图像处理和数据库生成：采集了1994-1999年日本海域和三陆附近的DMSP/OLS图像，生成了捕捞船队分布的数据库。(2)卫星海温和海色图像的处理和数据库的生成。我们收集了1994-1999年覆盖日本海和三陆附近的NOAA/AVHRR、ADEOS/OCTS、Orbview-2/SeaWiFS图像，生成了SST和叶绿素a数据库。(3)利用高度计海面高度资料研究了中尺度涡旋、黑潮暖核环(Kuroshio暖核环)和Tsugaru暖流涡旋(TWCG)的分布利用TOPEX/ERS-2海面高度距平资料。(4)鱿鱼捕捞船队分布的统计分析。(5)捕捞船队分布与SST分布关系的分析。(7)太平洋刀鱼迁徙路线分析1995年和1998年KWCR-93A和TWCG的结合切断了作为太平洋刀鱼迁徙路线之一的Oyashio第一分支的入侵。渔场向近海转移表明，合并是改变迁徙路线的重要现象。
