The authors honor the memory of Peter Niiler, without whose vision, energy, and forcefulness there would have been no Global Drifter Program. We acknowledge the helpful comments from the two anonymous reviewers. The OSCAR data were obtained from JPL Physical Oceanography DAAC and developed by ESR. This publication is funded by NASA under JPL Subcontract 1377557 and the Joint Institute for the Study of the Atmosphere and Ocean (JISAO) under NOAA Cooperative Agreement NA10OAR4320148.
