格陵兰-苏格兰海脊系统不仅是挪威-格陵兰海盆和北大西洋中纬度海盆之间的地形分界线，而且在不同气候来源的水团分隔带的位置上也起着决定性的作用。这一点很容易在图1中显示，脊线系统是一个温度反差很大的区域。图2描述了汇聚在那里的最重要的水团的温度和盐度特征。这两个极端是起源于海脊以南的高盐度和高温的大西洋水域和温度较低和盐度较低的极地水域，它们的起源与受融化和径流进入极海的表层水域有关。这两个北极水域(中层和深层)的盐度相对较高，来自大西洋水域，而较低的温度来自格陵兰-挪威海的冷却。
The Greenland-Scotland ridge system is not only a topographical boundary between the basins of the Norwegian-Greenland seas and the basins of the mid-latitude North Atlantic, but it also plays a decisive role in the location of the zone separating water masses of different climatological origin. This is readily demonstrated in Figure 1 showing the ridge system to be an area of strong temperature contrasts. The most important water masses merging there are characterized in Figure 2 by means of their temperature and salinity characteristics. The two extremes are Atlantic waters with high salinities and high temperatures originating from south of the ridge and Polar waters with low temperatures and low salinities relating their origin to surface waters influenced by melting and run-off into the Polar Sea. The two Arctic waters (intermediate and deep) received their relatively high salinities from Atlantic waters and have obtained their low temperatures from cooling in the Greenland-Norwegian seas.
