Direct evaluation of sea-ice production in the Sea of Okhotsk based on in sites ice-thickness observations

1999-2001年冬季，在北海道沿海地区的汤别外获得的海冰系泊数据显示，平均吃水为0.60 m，变形冰比率高达80%。这些结果发表在Jiamachi et al.（2006，Journal of Geophysical Research）。此外，沿着2005-06年冬季在Mombetsu附近获得的海冰系泊数据以及国家环境研究所收集的沉积物收集器数据表明，下沉的生物和岩石物质的质量和数量随海冰覆盖而变化。这些结果发表在Hiwatari等人（2008年，《极地科学》）上。分析了2002-03年冬季在萨哈林岛北方附近获得的海冰和海洋系泊数据。这些数据表明，平均吃水（1.05 m）显著大于北海道外海，在近海和陆上海冰流速下，出现了<0.2m和> 5 m的厚冰期，在薄冰期海水盐度增加，导致产生了密度超过26.7的密集陆架水，根据大气、海冰和海洋之间的热通量计算，与海冰产生相关的盐水排斥很好地解释了观察到的水-盐度增加。这些结果摘要载于提交大陆架研究报告的Jiamachi等人的论文中。

Sea-ice mooring data obtained off Yubetsu in the Hokkaido coastal region during the winters of 1999-2001 revealed the mean draft of 0.60m and the high deformed ice ratio of 80%. These results were published in Fukamachi et al. (2006, Journal of Geophysical Research). Also, sea-ice mooring data obtained off Mombetsu during the winter of 2005-06 along with the sediment-trap data collected by the National Institute for Environmental Studies indicated that the quality and quantity of sinking biogenic and lithogenic materials varied with the sea-ice cover. These results were published in Hiwatari et al. (2008, Polar Science).Sea-ice and oceanic mooring data obtained off the northern Sakhalin during the winter of 2002-03 were analyzed. These data revealed that the mean draft (1.05m) was significantly larger than that off Hokkaido, periods of thin- (<0.2m) and thick-ice (>5m) occurred with offshore and onshore sea-ice velocities, sea-water salinity increased during the thin-ice periods resulting the production of dense shelf water with potential density exceeding 26.7, the observed water-salinity increase is well explained by the brine rejection associated with sea-ice production based on the heat-flux calculation among the atmosphere, sea ice, and ocean. These results were summarized in Fukamachi et al. submitted to Continental Shelf Research.
