摘要: 利用1999年7~9月中国首次北极科学考察队北极科学考察,在白令海获得的42个站次的CTD资料,分析了白令海中北部的温度、盐度垂直分布特征,讨论了白令海的夏季表层水和冬季残留水的分布和结构,以及陆架坡折处温盐锋及白令海的水因特征.与多年平均资料相比,1999年7月夏季白令海冷中间层的温度,比多年平均温度低1℃以上,盐度低0.2左右.Abstract: Based on CTD data of the 42 stations in the Bering Sea obtained by the Chinese First Arctic Research Expedition in July to November 1999,the horizontal and the vertical distribution of the temperature and salinity,the feature of the water masses,the fro ntnear the slope of the Aleutian Basin are analysed and discussed.In July 1999, the temper ature and salinity of the Bering cold center water is lower about 1℃ and 0.2 than the Levitus 94 monthly mean data.
