Drift ice attached to coasts of Hokkaido

White lines of drift ice had been spotted off the coast of Wakkanai on January 25, according to the Wakkanai Local Meteorological Observatory. The ice came 19 days earlier than usual. Abashiri Local Meteorological Observatory reported this year's first drift ice came into view off the Abashiri coast On January 31 ten days later than usual and the ice became attached to the land on February 2.

Each year, the Wakkanai, Kushiro and Abashiri local meteorological observatories announce the first day that this ice can be seen with the naked eye from the coast, the last day that the ice could be seen, the day that sea routes became unnavigable due to the ice attached to the land along coastlines and the day that sea routes became navigable.

However observations of drift ice started to ensure the safety of navigation. Sea ice is a barrier to shipping, and making it impossible for fishing vessels to access fishing grounds. Abashiri Weather Station(current Abashiri Local Meteorological Observatory) has observed drift ice since 1892. The Ice Information Center by 1st Regional Coast Guard Headquarters provides information about drift ice in coastal waters off northeastern Hokkaido.

The following web site provides information on drift ice for tourists:

On the other hand, drift ice is the key driver of the coastal waters' ecosystem. Fresh water of the Amur River flows into the surface layer of the Sea of Okhotsk. Suraface sea water diluted with river water freezes more easily than ordinary sea water. Salt gets left in the liquid as salt water starts to freeze. The concentrated salt water sinks to the ocean bottom resulting in a mixing of the layers. Dense salt waters bring cold, nutrient-rich deep waters to the ocean surface, replacing nutrient-depleted surface water. The nutrient-rich upwelled water fosters the intense growth of phytoplankton called ice algae, which live in and under the drift ice is the foundation of the bountiful marine food web. Krill feeds on phytoplankton that grows on the underside of sea ice and provides an important food source for sea creatures.

Clione limacina, known as sea angel, are carried to the Sea of Okhotsk by the northern coast of Hokkaido, clinging to the undersides of the ice. Its earliest-stage larvae feed on phytoplankton and adults feed exclusively on a small herbivorous sea snail, Limacina helicina. They are pray for salmons. Visitors can also see them at the Okhotsk Ryuhyo(drift ice) Museum (https://www.ryuhyokan.com/)
