    Description: The archive contains data of measurements of the Malvinas Current performed on multiple occupations of five transects across the flow. The data were collected using a Shipborne Acoustic Current Profiler (SADCP) in 2016-2020. We used a Teledyne RD Instruments Ocean Surveyor (TRDI OS) SADCP with a frequency of 76.8 kHz and range of 700 meters. Temporal averaging was made over 120 s. All data were collected using VmDas software. The .STA files (see Other version) can be processed by standard WinADCP software.
