1999年白令海夏季水文特征分析

Hydrologic features of the Bering Sea in the summer of 1999

利用 1 999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 ,1 999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 .

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 front near the slope of the Aleutian Basin are analysed and discussed. In July 1999,the temperature and salinity of the Bering cold center water is lower about 1 ℃ and 0 2 than the Levitus94 monthly mean data.
