Pan-Okhotsk Symposium

The Center has reached the milestone of its 15th anniversary. During this time in the Pan-Okhotsk region, Global Warming progresses in real time. The effects of Global Warming is beginning to appear as sensitive, as weakening of Siberian High, decreasing of sea ice extent, warming of intermediate layer of ocean, changing in cryosphere, and so on.

This time, we would like to hold a symposium "Changing of Land and Ocean in Pan-Okhotsk region and the Future Prospects"to have an opportunity to summarize the researches in Pan-Okhotsk region that has progressed in many kinds of research fields, and to discuss future prospects.

Date:July 26-27, 2019

Venue:Auditorium, Institute of Low Temperature Science

The Pan-Okhotsk Area literally denotes the Sea of Okhotsk and its surroundings. However, we consider this area to be a much broader area, encompassing the Eurasian Continent and the North Pacific Ocean zonally; the region is also exposed by the arctic and tropical influences meridionally. The Sea of Okhotsk is know to be the souhernmost sea ice extent in the Northern Hemisphere because it is located immediately eastward of the Siberia. Sea ice gives various kinds of influences to the global environment. We have particularly paid attention to the subduction of dense waters produced when sea ice forms, which ventilates the intermediate water and transports nutrient materials and gases in a long distance. It has been found that iron, a micro nutrient necessary for photosynthesis, originates in the Amur River, flows out to the Sea of Okhotsk and is transported through this intermediate-layer pathway, which is finally utilized for biological production in the western North Pacific. Therefore, we should assess carefully the impacts of global warming and anthropogenic land use.

The Pan-Okhotsk Research Center was established in 2004 attached to the Institute of Low Temperature Science, Hokkaido Univresity, to foster international collaborations and study environmental issues associated with the Sea of Okhotsk and surrounding regions. The center was restructured in 2013, and the two sections, "Climate Change Research Section" and "Land-Ocean System Section", were established. Further, "International Research Promotion Office" was organized to foster the international collaborations based on the research networks that we have established in the past years. We believe that novel research field will emerge based on the developments of the international research community with the long term perspective.
