Sea ice covers 10% of the earth's oceans, which produces dynamic cycles in the atmosphere and in the oceans as a major factor in the global heat balance.
  The Sea of Okhotsk is the lowest latitude freezing sea in the world, and the coast of Hokkaido is the southern limit of sea ice in the Northern Hemisphere. Every winter, 60-70% of the Sea of Okhotsk is covered with sea ice, which has both merits and demerits in human lives.
  Furthermore, the sea ice extent in the Arctic Ocean has decreased rapidly due to the recent global warming, which is a serious environmental problem. On the other hand, the opening of the "Arctic Sea Routes" between the Pacific Ocean and Europe has become a new subject.
  For these reasons, sea ice deeply relates to the global environment and also to human activities such as fisheries, agriculture, and industry. Our Symposium will cover a variety of topics of the latest sea ice researches, global warming, environment change in polar regions, biology and fisheries, Arctic Sea Routes, and many subjects in the Okhotsk region.
 The International Symposium on Okhotsk Sea & Polar Oceans has been held every year in Mombetsu since 1986, and has counted 35 times in 2020. In 2021, the Symposium was canceled due to the new coronavirus. However, in 2022, we can hold the online academic sessions as the 36th Symposium. We hope that many participants will have fruitful discussions at this Symposium.
