摘　　要：依据 1 999年 7月至 9月中国首次北极考察队在白令海、楚科奇海和南加拿大海盆的现场调查资料 ,本文分析了三个海区的水团特征 :( 1 )白令海水团主要由季节变化显著的白令海上层水团和中层水团以及深层水团组成 ;( 2 )楚科奇海水文特征受融结冰过程影响较大 ,1 999年7月和 8月差异较大 ,其水团主要为浅海变性水团 ,包括两个次级水团 ,楚科奇海夏季水和来自北太平洋以及北冰洋变性的外海入侵水 ;( 3)南加拿大海盆的水团主要由受融结冰过程影响的表层水团、源于太平洋水的次表层水。Based on the conductivity temperature depth (CTD) data obtained within the Bering Sea, Chukchi Sea and south Canada Basin by Chinese First Arctic Research Expedition from July to September 1999, the assemblies of water mass in the three area are analyzed: (1) The water mass in the Bering Sea consists of the Upper Water changed with season, the Intermediate Water and the Deep Water (2) The Chukchi Sea water is influenced by input water of outer sea and variation of sea ice. The hydrographic features are different in July from in August evidently. Water mass assemblies in the Chukchi Sea are defined as distorted water for shallow sea and include the Chukchi summer water and the input water source from the north Pacific Ocean and Arctic Ocean. (3)In the south Canada Basin, the main components of water mass are the Arctic Surface Water effected by variation of sea ice, the Arctic Subsurface Water of Pacific origin, the Arctic Intermediate Water of Atlantic origin and the Arctic Deep Water.
