知床半島
The cold Oyashio Current flows southwest along east side of the peninsula, and the Soya Current flows southeast from the Sea of Okhotsk until it is redirected north along the west side of the peninsula. In winter, the Soya Current carries sea ice south from the Sea of Okhotsk where it dams along the west side of the Shiretoko Peninsula resulting in the lowest latitude regularly occurring sea ice on earth at 43 degrees north.
