The mid-depth circulation of the subpolar North Atlantic Ocean as measured by subsurface floats

The multi-year mean, mid-depth circulation of the subpolar North Atlantic Ocean from direct velocity measurements obtained over a 7.5-year period by 211 neutrally-buoyant, profiling, subsurface floats is estimated. A statistical analysis of these velocity data is presented and features of the circulation from 400-1500m dept as measured by the floats is described.
