冰岛以东大陆架和冰岛-法罗海脊西部的环流和水文地理是通过使用温盐剖面仪、系泊海流计和卫星跟踪漂流器进行的一系列调查来描述的。该地区的主要表面电流是北大西洋水在冰岛东南部的陆架断裂处向东北流动，因为它离开陆架加入冰岛-法罗群岛前线。在它下面的海底，有一股强大而稳定的水流，从北欧海溢出，沿着沿着流动。在锋面的北面，有三个相对较弱的海流，是由北冰岛伊明格海流绕过冰岛东北角后分裂而成的。一个分支，东冰岛海流，被限制在大陆架上，并产生一个平均的，向南的流动，直到它转向东加入冰岛-法罗阵线。另一个离开大陆架，形成了浅的，向东南流动的冰岛海流。第三个沿着大陆坡较深的轮廓，在冰岛-法罗海脊的北方侧翼更新沃茨。
Circulation and hydrography on the shelf east of Iceland and on the western portion of the Iceland-Faeroe Ridge is described by a series of surveys using temperature-salinity profilers, moored current meters and satellite-tracked drifters. The dominant surface current of the region is the northeastward flow of North Atlantic Water at the shelf break southeast of Iceland as it leaves the shelf to join the Iceland-Faeroe Front. On the bottom beneath it flowing in the opposite direction is a strong, steady current composed of water from the Nordic Seas that has overflowed the ridge and followed along bathymetric contours. North of the front, three comparatively weak currents are identified, formed by splitting of the North Icelandic Irminger Current after it has rounded the northeast corner of Iceland. One branch, the East Icelandic Current, is confined to the shelf and produces a mean, southward flow until it turns eastward to join the Iceland-Faeroe Front. Another leaves the shelf to form the shallow, southeastward flowing Icelandic Current. The third follows deeper contours of the continental slope and renews waters on the northern flank of the Iceland-Faeroe Ridge.
