Study of the Ocean and the Earth Dynamics by International TOPEX/POSEIDON Program

这一方案是从1993年至1995年期间的。1993年8月，濑川和中川赴北京参加了IAG大会的Topex-Poseidon会议，11月在法国图卢兹举行了名为“Topex-Poseidon推出一年后”的研讨会，今胁、大江和柴田出席了会议。1994年6月，濑川访问了位于巴黎的法国空间研究中心，讨论了Topex-Poseidon的数据格式。8月，杜博士访问英国剑桥大学和法国布雷斯特大学，参加海平面变化与地磁变化的研讨会。12月，今胁、川村和福田出席了在旧金山弗朗西斯科举行的AGU大会情况下举行的Topex-Poseidon研讨会。1995年7月，濑川和田村前往美国博尔德参加IUGG会议。10月5日，调查人员，即，今胁、大江、久保田、市川、松本等赴法国比亚里茨参加Topex-Poseidon的SWT会议，在本研究期间，6名外国研究人员应邀赴日。1993年，两名澳大利亚人白色和海森乘坐东京大学海洋研究所的丹生丸号R/V来进行合作研究。1994年，法国人Gaspar和澳大利亚人科尔曼应邀访问日本，通过对Topex-Poseidon三年来的观测资料进行分析，得到了新的黑潮模型、日本列岛大地水准面模型和更精确的世界海潮模型。与国外研究人员的交流对这些研究非常有用。

This program is for the period from 1993 through 1995. In this period 17 investigators were dispatched to China, France, England and the United States, respectively.In August 1993 Segawa and Nakagawa visited Beijing to attend the Topex-Poseidon Session in the General Meeting of IAG.In November there was a symposium named '1 year after the launch of Topex-Poseidon' in Toulouse, France, which Imawaki, Ooe and Shibata attended. In June 1994 Segawa visited the France Space Research Center in Paris to discuss about the data format of Topex-Poseidon. In August Toh visited Cambridge University of England and Brest University of France to attend the seminer on the sea level changes versus geomagnetic variations. In December Imawaki, Kawamura and Fukuda attended the Topex-Poseidon Symposium held in the case of AGU general meeting in San Francisco. In July 1995 Segawa and Tamura visited Boulder, USA to attend the IUGG meeting. In October 5 investigators, i.e., Imawaki, Ooe, Kubota, Ichikawa and Matsumoto visited Biaritz, France to attend the SWT meeting of Topex-Poseidon.In the course of the period of the present research 6 foreign researchers were invited to Japan. In 1993 two Australians White and Heinson came to make co-operative research on board R/V Tansei-Maru of the Ocean Research Institute, the University of Tokyo. In 1994 one French (Gaspar) and one Australian (Coleman) were invited to Japan.Through the extensive analysis of Topex-Poseidon data carried out for the last 3 years we could get new models of Kuroshio Current, Geoid around the Japanese Islands or more precise oceanic tide of the world. The communication with foreign researchers were very useful for these studies.
