Hiroshi Ueda of Hokkaido University will take part in an international research project put together by a group of North American and European scientists to clarify the behavior and ecology of small and large marine creatures, including whales.

The marine tracking network will be carried out as part of a 10-year Census of Marine Life project that has been put forward by the United Nations and other bodies to survey living things in the seas by 2010.

Ueda and his group plan to examine migratory routes of tuna in the Northwestern Pacific centering on the coast of Hokkaido.
