Inter-annual and year-to-year variability in hydrometeorological parameters, snow and sea-ice has been studied with AWSs (Automated Weather Stations), IPSs/ADCPs (Ice Profiling Sonar/Acoustic Doppler Current Profiler), EM (Electromagnetic Induction Sounding of snow/sea-ice thickness measurements) at/offshore Chaivo, northeastern Sakhalin and Saroma-ko lagoon, Hokkaido in the Sea of Okhotsk. The model of snow/sea-ice thickness evolution was verified to agree well with those observed data.Ice climatology was also studied in the Baltic Sea to compare that in the Sea of Okhotsk, as representatives of a seasonal sea ice zone.Ship-borne EM measurements of snow/sea-ice thickness were carried out in the Sea of Okhotsk, Antarctic Ocean, Chukchi Sea, Beaufort Sea and trans-Arctic Ocean from the Bering Strait to the Fram Strait via the North Pole to investigate spatial, seasonal and year-to-year variability in sea-ice thickness.An ice-ocean coupled model was applied to the Arctic Ocean to understand processes of air-sea-ice-ocean interactions in the Arctic. It appeared that most of the Arctic sea ice consisted of deformed ice in association with atmospheric variability in 10 year cycle.

在鄂霍次克海的萨哈林岛东北部的Chaivo和北海道的Saroma-ko泻湖/近海，利用AWS（自动气象站）、IPS/ADCP（冰剖面声纳/声学多普勒海流剖面仪）、EM（雪/海冰厚度测量的电磁感应探测）研究了水文气象参数、雪和海冰的年际和年际变化。在此基础上，对鄂霍次克海、南极海、楚科奇海、波罗的海和南极洲的海冰厚度进行了船载电磁观测，并对北极海冰厚度进行了分析。博福特海和跨北冰洋从白令海峡到弗拉姆海峡经北极考察空间，海冰厚度的季节和逐年变化。冰-海洋耦合模式应用于北冰洋，以了解空气-海冰-北极的海洋相互作用。结果表明，在10年周期内，北极海冰主要由与大气变化有关的变形冰组成。
