SADCP measurements of the Malvinas Current at 43-47°S in March 2020
Field measurements of the Malvinas Current velocity distribution were performed at a few locations of the western slope of the Argentine Basin in the South Atlantic Ocean between 47° and 43°S including several sections across the current.
