Development of advanced observation systems for GLOBEC

为了在日本和世界范围内推广GLOBEC项目，有必要建立海洋生物采样和观测的技术基础。伍兹霍尔海洋研究所拥有世界上最先进的海洋生态系统生物观测系统。为此，海洋研究所(ORI)和WHOI开始了开发新观测系统的联合研究。ORI于1996年6月利用现有的仪器和原型仪器在伊豆地区、黑潮延伸区、黑潮-大洋洲过渡区进行了海洋观测。世界卫生组织的S·加拉格尔博士于1996年11月应邀访问日本。随后，举行了《浮游动物采样观测》工作坊。T.T.Komatsu博士和S.Kimura博士访问了美国WHOI，讨论了通过声学或图像分析对浮游动物进行采样、观测和自动化分析。ORI于1997年6月在黑潮延伸区和黑潮-Oyashio过渡区进行了两次观测巡航，并于1997年10月在三陆附近的暖芯环进行了这项研究。世界卫生组织在大西洋的乔治斯浅滩进行了观测，相当于日本三陆附近的水域。T.Sugimoto，H.Nakata和I.Aoki博士访问了美国，讨论了ORI在日本和WHOI在美国的观测结果。ORI于1998年7月使用各种仪器进行了海洋观测，并于1998年9月至10月在三陆附近的黑潮延伸区、Oyashio-黑潮过渡区和暖核环进行了海洋观测。世界卫生组织在乔治斯银行发表了与1997年相同的意见。杉本博士和小松博士分别于1998年8月和1999年3月访问了美国，讨论了观测结果和未来的合作。这项研究将继续进行到计划于1999-2000年在日本海对GLOBEC进行的WHOI和ORI合作生物观测。

It is necessary to establish technological fundamentals of biological sampling and observation in the ocean for promoting GLOBEC project in Japan and in the world. Woods Hole Oceanographic Institution (WHOI) has the most advanced biological observation system of ocean ecosystem. Thus, the joint study to develop new observation systems was started as a cooperative research between Ocean Research Institute (ORI) and WHOI.ORI made oceanographic observation in the Izu Region, Kuroshio Extension, Kuroshio-Oyashio Transition Region by using present instruments and proto-type instruments in June 1996. Dr.S.Gallager of WHOI was invited to Japan in Nov. 1996. Then, the work shop on "Sampling and observation of zooplankton" was held. Drs. T.Komatsu and S.Kimura visited WHOI in USA to discuss on sampling, observation and automated analysis of zooplankton by acoustic or image analysis.ORI conducted two observation cruises for this study in the Kuroshio Extension and Kuroshio-Oyashio Transition Region in June and in Warm Core Ring off Sanriku in Oct. 1997. WHOI made observations in Georges Bank in the Atlantic equivalent to waters off Sanriku in Japan. Drs.T.Sugimoto, H.Nakata and I.Aoki visited USA to discuss results of observations by ORI in Japan and those by WHOI in USA.ORI conducted oceanographic observation using various instruments in July 1998 and in the Kuroshio Extension, Oyashio-Kuroshio Transition Region and Warm Core Ring off Sanriku from Sep. to Oct. 1998. WHOI made the same observation in Georges Bank as in 1997. Drs.T.Sugimoto and T.Komatsu visited USA to discuss the observation results and future cooperation in Aug.1998 and in Mar.1999, respectively. This study will continue through the future WHOI and ORI cooperative biological observations for GLOBEC scheduled in Japan Sea in 1999-2000.
