挪威海的深水流入北大西洋的大部分是通过法罗岸海峡，这是穿过格陵兰-苏格兰海脊的最深通道。为了估计这一冷，低盐底层水的流量，现场调查，包括水文观测以及目前的测量进行了1983年5月期间在该通道。对总共四组观测数据进行了运输计算，得出的数值范围为1.5至1.9 sverdrup。流出是最有可能受到液压控制，因此，一个简单的模型已经制定，以确定通过旋转通道的抛物线截面的最大流量。这种几何形状很好地适应了地形的法罗银行渠道，理论上预测的规模的运输被认为是在良好的协议与观测。
A substantial part of the Norwegian Sea deep-water outflow into the North Atlantic takes place via the Faroe Bank Channel, the deepest passage through the Greenland-Scotland Ridge. In order to estimate this flux of cold, low-saline bottom water, a field survey comprising hydrographie observations as well as current measurements was carried out in the channel during May 1983. Transport calculations were undertaken for a total of four sets of observations and yielded values ranging from 1.5 to 1.9 sverdrup. The outflow is most likely subjected to hydraulic control, and consequently, a simple model has been formulated in order to determine the maximum discharge through a rotating channel of parabolic cross section. This geometry is well-adapted to the topography of the Faroe Bank Channel, and the theoretically predicted magnitude of the transport was found to be in good agreement with the observations.
