Earlier activities for GEOTRACES in Japan

In Japan, discussion to participate in GEOTRACES was begun in earnest around 2003.

In 2005, a subcommittee on GEOTRACES was established in Science Council of Japan with limited term. In order to initiate a national GEOTRACES project under the grant-in-aid scientific research of Ministry of Education, Culture, Sports, Science and Technology (MEXT), a proposal was developed with 20 researchers including the members of the GEOTRACES subcommittee in 2005. Although, unfortunately, this proposal as all Japan was not accepted by MEXT, some research activities related to GEOTRACES have been implemented with efforts of Japanese researchers.

Japanese cruises and research activities are introduced on another page of this web page: Research Plans

International GEOTRACES Project is shifting from a planning phase to an implementation phase of its field works. GEOTRACES Science Steering Committee has been established involving two Japanese researches since 2006. The first full scale Japanese cruise met with the requirement of GEOTRACES was conducted in Indian Ocean by R/V Hakuho Maru from November 2009 to January 2010.
