석호(Open water) 안쪽의 좌우로 보면, 얼음이 형성된 것을 볼 수 있습니다.
홋카이도의 이 동네가, 북극의 유빙을 볼 수 있는 지구상에서 가장 저위도 지역이라고 합니다.

저렇게 흘러온 유빙은, 봄철에 녹아서, 플랑크톤을 제공하기 때문에, 어족자원의 보고가 된다고 합니다.


The Sea of Okhotsk has long been home to our planet’s southernmost Arctic sea ice. Ice spreads southward out of the Arctic each winter, along the eastern edge of Sakhalin Island (or Sakhalinskaya Oblast), which lies immediately north of Hokkaido. Historically, the southernmost tip of the Arctic sea ice has touched Hokkaido’s northern coast.
Besides providing habitat for seabirds and marine mammals, sea ice—also known as drift ice—in this region promotes the growth of phytoplankton. When sea ice melts, it leaves nutrient-rich freshwater in its wake. These waters encourage phytoplankton to grow, thereby playing a crucial role in the marine food chain. Between 1979 and 2008, however, sea ice in the Sea of Okhotsk gradually declined. Despite a spike in the winter of 2001, sea ice extent declined sharply after the year 2000.
