对一系列盐度产品的研究共同表明，从2000年代中期到现在，北大西洋的淡水化普遍存在。每月的盐度场显示负趋势，在北大西洋西部和东部地区之间的幅度和意义不同。这些差异可以归因于大的负年际漂移在西部副极地环流和拉布拉多海，这是不明显的中部或东部副极地环流的盐度。这项研究表明，在西北部（包括拉布拉多海）的盐度的时间趋势受到的机制是不同的，从那些负责在北大西洋中部和东部的盐度趋势。在副极地环流西部，近地表盐度与副极地环流强度呈负相关，这表明负盐度异常与副极地环流的加强有关，这是造成淡水通量增加的原因。
AbstractExamination of a range of salinity products collectively suggests widespread freshening of the North Atlantic from the mid-2000s to the present. Monthly salinity fields reveal negative trends that differ in magnitude and significance between western and eastern regions of the North Atlantic. These differences can be attributed to the large negative interannual excursions in salinity in the western subpolar gyre and the Labrador Sea, which are not apparent in the central or eastern subpolar gyre. This study demonstrates that temporal trends in salinity in the northwest (including the Labrador Sea) are subject to mechanisms that are distinct from those responsible for the salinity trends in the central and eastern North Atlantic. In the western subpolar gyre a negative correlation between near-surface salinity and the circulation strength of the subpolar gyre suggests that negative salinity anomalies are connected to an intensification of the subpolar gyre, which is causing increased flux of freshwa...
