[HTML][HTML] Vertical structure of ocean surface currents under high winds from massive arrays of drifters

J Lodise, T Özgökmen, A Griffa, M Berta - Ocean Science, 2019 - os.copernicus.org
Very-near-surface ocean currents are dominated by wind and wave forcing and have large
impacts on the transport of buoyant materials in the ocean. Surface currents, however, are …
