ADCP current measurements (75 kHz working area dataset) during RV MARIA S. MERIAN cruise MSM105
Upper-ocean velocities along the cruise track of RV MARIA S. MERIAN cruise MSM105 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.0 m below the water line. The instrument was operated in broadband mode with 8 m bins...
