Drift ice

Drift ice seen from the coast

If you wish to have a first-hand experience of drift ice, you can go down to the coast.
There are not many shore reefs on the coastline of Abashiri. Instead, sandy beaches spread. When drift ice approaches, you can see it from close up on the coastlines between Futatsuiwa and Maehama, and between Masuura and Kitahama. Then you will realize that a lump of drift ice is surprisingly large. Even outside the season for drift ice, you can see actual drift ice at Okhotsk Ryu-hyo Museum in Mt. Tento at any time.

Trivia about drift ice

Ice floating in the sea is generally called "ryuhyo (drift ice)". But when sea water is frozen, it is called "sea ice", compared with "river ice" which is water frozen in rivers and lakes and "icebergs" which are snow turning into glaciers and flowing into the sea. To be exact, most of the drift ice in the Sea of Okhotsk is actually "sea ice".
Along the northwest coast facing the Sea of Okhotsk, when seawater is chilled to minus 1.8 degrees by an extremely cold wind, it turns into small needle-like or plate-like pieces of ice near the surface of the sea. This is the way ice crystals are generated. The amount of ice crystals increases little by little until the sea surface is covered by them. They collide and connect with one another to grow into ice in the form of a lotus leaf.

Lotus leaves of ice generated around November slowly go south in the Sea of Okhotsk, driven by a strong north-west monsoon and the East Sakhalin Current, while growing larger. They reach the Okhotsk coast of Hokkaido from late January to early February.
The concentration of salt in the drift ice is around 0.5%, less than one-sixth of that of the seawater. When ice crystals connect with one another to grow into larger crystals, salt, which is difficult to freeze, is left behind. Such a condition can be clearly seen if you observe drift ice with a microscope.
The fishery in the Sea of Okhotsk temporarily stops operation when drift ice comes. However, under the drift ice, a great amount and many types of plankton are active, including clione. In fact, a very large amount of cold-water fish surges in pursuit of such plankton. An abundance of marine resources in the Sea of Okhotsk is protected by nature itself.
