Short summary
Understanding meltwater circulation around Greenland is crucial as it could influence climate variability but difficult as data are scarce. Here, we use 34 surface drifters to evaluate satellite-derived surface currents and show that satellite data recover the general structure of the flow and can recreate the pathways of particles around the southern tip of Greenland. This result permits a wide range of work to proceed looking at long-term changes in the circulation of the region since 1993.
