During the fall of 1987 the Autumn Circulation Experiment (ACE) was carried out in the northern North Sea. The transversal flow of mixed Scottish coastal and Atlantic water from northeast of Scottland towards Norway was clearly observed through the thermohaline, nutrient and current distribution. A significant core of high salinity Atlantic water were found to the north of this, demonstrating a pronounced flux of Atlantic water onto the northern North Sea plateau. A topographically steered cyclonic eddy with a scale of 100 km was clearly documented. A major barotropic southeastward flow towards Skagerrak of cold, heavy bottom water from the northern plateau was revealed, in addition to the more well known circulation in the vicinity of the Norwegian Trench.
