Repeated ADCP sections without acoustic bottom reference and based on the directly observed athwartship velocity component have been worked across the surface water mass of the Faroe Bank Channel. A pronounced inhomogeneity of the current field was observed at depths of around 300 m. This anomaly could be correlated to the hydrographic observations which were undertaken throughout the experiment, since the pertinent segment of the temperature-salinity (T-S) relationship showed the presence of a water mass with characteristics deviating from those normally encountered in this zone. The outcome of a set of extended dynamic calculations furthermore showed that over this range of depths the observed velocity structure could not be accounted for solely in terms of geostrophic motion. ¿ American Geophysical Union 1989
