PURPOSE OF SYMPOSIUM
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.

Almost 10 % of the earth's ocean is perennially or seasonally covered with ice layers. variations in the sea ice cover have profound effects on the global heat balance and thus relate to the dynamic cycle of the atmosphere and of the ocean.
The Sea of Okhotsk is known as Japan's only "freezing" sea, with its frozen coastal waters along Hokkaido being the southernmost (44deg.00'-45deg.30'N) on the Northern Hemisphere. Up to 60～70% of the Okhotsk surface is ice covered during the winter, hampering navigation and fishing operations. It is true that sea ice increases marine productivity but it can cause problems such as marine accidents, damage to equipment and rigs that are in the water, and damage to field crops due to cold weather. With development of seabed resources such as oil and gas, advanced studies in marine structures and ice engineering are in great demand.
The Okhotsk Sea & Polar Oceans Symposium is organized annually by City of Mombetsu. The objectives of this annual symposium are to promote the advancement of all ice-related studies such as oceanography, meteorology, biology and fisheries, to explore what may be common in various fields, to review the latest developments in these fields, and to outline new directions for future research. It is our hope at this 36th International Symposium that many excellent presentations and discussions amongst participants will lead to deeper understanding of sea ice studies.
We was planning to hold the 36th Okhotsk Sea & Polar Oceans Symposium in Mombetsu 2021, it will be canceled.
We call for papers manuscripts as scheduled, OSPOR journal [Volume 5, (2021)] will be published, even if the symposium is not held.
