Major achievements
Dr. Takeshi Tamura has focused on polar sea ice and has made numerous achievements on the effects of polar sea ice on the global climate.
A particularly notable achievement is the development of a “sea ice thickness algorithm” specifically for estimating sea ice production.
Using this algorithm, he succeeded in mapping global sea ice production from satellite data for the first time in the world, bringing about a breakthrough in the field of polar science.
In addition, the elucidation of the melting process of the base of glaciers has had a great impact on the world, and it has been found that the offshore Totten Glacier is important as a melt-promoting zone in East Antarctica.
This result received a great deal of attention because there were almost no reports of glacier melt in East Antarctica compared to West Antarctica.
As a result, the offshore Totten Glacier was planned as an important observation area for the current 6-year Japanese Antarctic Prioritized Research Project (phase X), ”Exploring future global environmental systems from the past and present Antarctica”.
SOOS, a subsidiary organization of the International Antarctic Science Committee, has also approved an international joint observation project with the United States, Australia, the United Kingdom, and Germany.
As mentioned above, Dr. Takeshi Tamura’s research has been recognized as an outstanding achievement by the domestic and international community, and he is a worthy recipient of the Nishida Prize.
