“…Yamazaki (2000) and Ogi and Tachibana (2006) suggested significant influence of the North Atlantic Oscillation or Arctic Oscillation on the Okhotsk Sea ice. Kimura and Wakatsuchi (1999) revealed that the ice-edge advance coincides well with that predicted by 2% of the geostrophic wind, and concluded that the ice advance is determined primarily by wind through ice advection. The ice advance eventually ceases even if the prevailing northwesterly wind continues.…”

“…This is reasonable since the sea ice advance is driven mainly by the prevailing northerly or northwesterly wind. Kimura and Wakatsuchi (1999) showed that the ice advance is explained by 2% of geostrophic wind for most years. However, in some years, such as in 1979 and 1980, the ice advance cannot be simply explained by the wind; in addition, the final ice advance or maximum ice extent cannot be explained by the wind (Kimura and Wakatsuchi 1999).…”

We examine the interannual variability of the sea ice area in the Sea of Okhotsk in terms of surface heat flux, using highly resolved flux data with the ice concentration taken into account. On the northwest and east Sakhalin shelves, where the initial ice formation occurs, the onset of ice formation is simply determined by the local heat flux in fall (October-November); the degree to which the ocean is cooled by the atmosphere. Consequently, this heat flux mostly determines the interannual variability of sea ice area in the Okhotsk Sea in the initial stage. The air temperature anomaly is the main cause of the heat flux anomaly in fall. The fall heat flux has persistently affected the ice area anomaly, particularly until mid-January. In the later sea ice season, the relationship between the ice area and heat flux is obscured, particularly after mid-January, by the heat insulating effect of sea ice. The ice area variabilities in the southern and northeast regions are correlated with the local heat flux in the months preceding ice appearance, but not strongly. Our analysis suggests that the heat flux does not determine to what extent the ice advances finally in the Okhotsk Sea. Typical heat flux distributions in heavy and light ice years are also presented from our heat flux data: the heat loss center is located in the central Okhotsk Sea in light ice years, and moves to the eastern Okhotsk Sea near the Kuril Straits in heavy ice years.

Abstract. Using daily sea ice data derived from satellite-borne sensors and atmospheric data, we examined processes controlling the variation of sea ice extent in the Northern Hemisphere. The daily ice motion field was computed from imagery of the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager (SSM/I) for seven winters (December to April) from 1991/1992 to 1997/1998, by employing the maximum cross-correlation method. In order to examine mechanisms of the temporal variation of the ice extent, we analyzed 50 specified lines across the daily ice edge. Although a high correlation between the ice motion and the geostrophic wind speed was observed in all the ice edge areas, the degree for correlation between the speed of the ice edge displacement and the wind speed varied with region. The degree for response of the ice edge speed to the wind speed largely depended upon that of the ice edge speed to the ice motion. The following mechanisms controlling the variation of ice extent for regions in the Northern Hemisphere were anticipated. In the Barents Sea, Bering Sea, and the Sea of Okhotsk the ice extent advances by wind-driven ice advection and the daily scale variation of the ice extent were also controlled by the variation in wind speed. In contrast, the ice extent in the Labrador Sea and the Greenland Sea seemed to be considerably affected by oceanographic factors such as the location of the thermal front and was not related to the variation in wind speed. The regional difference of the variation mechanism was also reflected in the interannual variation in maximum ice extent.

“…The largest range of modern sea ice expansion has reached the southeastern part of the Okhotsk Sea, near the Kuril Basin (Minervin et al, 2015). The expansion and retreat of modern sea ice are considerably affected by wind and temperature (Kimura and Wakatsuchi, 1999). Under the effect of wind and currents, sea ice drifts from the north to the southeast.…”

In this study, we investigate light and heavy minerals in sediment core OS03-1 located at the Academy of Sciences Rise of the southern Okhotsk Sea to determine their distributions and sources over the last 180 ka (thousand years). The sediment mainly consists of terrigenous and volcanic detritus. Ubiquitous drop-stones and volcanic detritus throughout the core and high detrital input suggest that sea ice, driven by wind and Kamchatka Current, was the main transport agent of detrital materials to the southern Okhotsk Sea. The ternary diagram of heavy minerals (hornblende-hypersthene-epidote) shows an expansion of detritus provenance from the eastern in cold periods to the northeastern in warm intervals of the Okhotsk Sea. It mainly relates to the shift of Aleutian Low. Combined with previous records, accumulation rates of quartz indicated a maximum extent but not perennial sea ice coverage during the glacial periods.
