2003年和2005年,水文数据提供了拉布拉多海足够的空间覆盖范围,以推断上拉布拉多海水(ULSW)的水团特征的流域范围内的变化。 2005 年 ULSW 的盐度和温度比 2003 年要高得多。尽管拉布拉多海的对流导致与低盐度的表层水混合,并且与观测到的盐度趋势相反,但 CTD 剖面的垂直均匀性增加、ULSW 厚度增加以及等重线势涡最小值的增强 σθ = 27.700–27.734 2005 年的 kg/m3 表明 2005 年冬季的对流至少对拉布拉多海地区的 20% 进行了通风。
In 2003 and in 2005, hydrographic data provided sufficient spatial coverage in the Labrador Sea to infer basin wide changes in the water mass characteristic of the Upper Labrador Sea Water (ULSW). The ULSW was considerably saltier and warmer in 2005 than in 2003. Although convection in the Labrador Sea leads to mixing with salinity‐poor surface water and is opposed to the observed salinity trend, the increased vertical homogeneity of the CTD profiles, the increase in the ULSW thickness and the intensification of the potential vorticity minimum for the isopycnals σΘ = 27.700–27.734 kg/m3 in 2005 point to convection in winter 2005 which ventilated at least about 20% of the Labrador Sea region.
