  Hydrochemical Atlas of the Sea of Okhotsk 2001
Coastal shallow zones in the Sea of Okhotsk are spawning and feeding grounds for numerous commercial fish species, as well as areas of alga Laminaria growth and accumulation of numerous populations of crab, shrimp, mollusk, and other invertebrates.
Unfortunately, previous oceanographic and hydrobiologic descriptions of the Sea of Okhotsk (Shmidt, 1950; Ushakov, 1953; Leonov, 1960; Zenkevich, 1963; Moroshkin, 1966) were based on measurements made during the period of formation of Russian oceanology and hydrochemistry, when the equipment and the methods were far from perfection.
Particularly significant changes were made in the well-known circulation scheme (Markina and Chernyavsky, 1984; Sea of Okhotsk, 1993) concerning the waters of the east coast of Sakhalin, the Yamsk upwelling zone, the Sakhalin Bay, the waters along the coastline of Kamchatka, and the Kuril Basin.

However, it is important for defining the plate boundary geometry and constraining the relative motion of the major and minor plate in Northeast Asia and provides a rigorous framework for interpreting seismicity and the surface deformation observed by geodesy.
The plate-motion parameters of the Okhotsk plate are consistent with right-lateral motion in northern Sakhalin and contraction in southern Sakhalin, inferred from focal mechanism solutions.

 IKIP: Island Info
Volcanic activity and uplift in the region of the Lesser Kuril Ridge intensified during the Paleocene and Eocene as the Kula-Pacific Ridge was subducted into the Kuril-Kamchatka Trench, and it was probably during this period that the Lesser Kuril Ridge emerged from the sea (Kimura and Tamaki, 1985).
During the hiatus of the late Eocene and Oligocene, the Okhotsk Plate was subsiding, and there is evidence that the Lesser Kuril Ridge may have been submerged during part of this period (Kimura and Tamaki, 1985).
Late in the Oligocene (approximately 30 million years before present) the Okhotsk Terrane began to rotate clockwise and the back-arc basin that now forms the southern Sea of Okhotsk began to open to the west of the Kuril Arc.

This means that the amount of sea ice in the Sea of Okhotsk was more than double the mean in 1979 in the region where the darkest blue occurs.
If we take a closer look at the variability within the Sea of Okhotsk, we can see that during the ten years that this data set was collected, there existed quite a change in sea ice concentration.
This means that if the mean sea ice concentration at a particular location in the Sea of Okhotsk is 40%, then the mean sea ice concentration for February 1979 is greater than 90% at the same point.

Den and Hotta (1973) proposed the existence of an Okhotsk plate during the Mesozoic and early Cenzoic on the basis of structural trends and orogenic belts in and around the Sea of Okhotsk (though their discussion does not require a distinct Okhotsk plate at present).
This unclear margin of the proposed Okhotsk plate may therefore be the result of the extrusion of parts of Asia by the collision of the Indian plate as proposed by Worral et al., (1996), and perhaps the lack of earthquakes in this area is due to high heat flow from crustal thinning.
Okhotsk plate is being extruded to the southeast, in a manner similar to the Anatolian plate between Eurasia and Arabia.

It transitions from the ultra-slow spreading Gakkel (Arctic) mid-ocean ridge in the Eurasia Basin of the Arctic Ocean, across a diffuse zone of extension in the continental crust of the Laptev Sea, into diffuse, presumed to be transpressional, zones in the Verkhoyansk and Chersky Ranges of northeast Asia which extend to Kamchatka and Sakhalin.
Many recent models incorporate an independent Okhotsk microplate (Cook et al., 1986; Parfenov et al., 1988; Seno et al., 1996), bounded in continental Asia by zones of active deformation, that is being extruded to the southwest (Riegel et al., 1993).
A similar local minimum of shear wave speed seems to lie along the western margin of the Sea of Okhotsk, in the baffling seismicity gap in the NW Sea of Okhotsk, which may be another patch of “deformable lithosphere.” Seismic reflection data, however, suggest that a band of faults crosses this region.

In winter, the Sea of Okhotsk is generally almost entirely covered with sea ice from late November to late May. Even in the southernmost part of the sea, along the northeastern sea coast of Hokkaido, the sea in general starts to freeze at early January and is covered with sea ice till late March.
The Sea Ice Research Laboratory (SIRL) of the Institute of Low Temperature Science, Hokkaido University was founded in Mombetsu in April 1965 to conduct studies mainly on sea ice and coastal oceanography.
