Short summary

In 2016 exceptional eddies visited a mooring array deployed in the Argentine Basin, a region where in situ data are scarce and ocean currents tend to be calm. The eddies had large rotating velocities and distinct physical characteristics and origins. One eddy with a radius of 100–150 km was bottom reaching. Two others were smaller with radii less than 40 km and depths of about 2500 m. The mooring data indicated the presence of waves trapped inside the eddies and favorable conditions for mixing.
