Upper-ocean velocities along the cruise track of RV MARIA S. MERIAN cruise MSM102 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 narrowband mode with 8 m bins and a blanking distance of 8 m, while 100 bins were recorded using a pulse of 1.43 s. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). Heading, pitch and roll data from the ship's gyro platforms and the navigation data were used by the data acquisition software VmDas internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and the ship's heading data. Further errors stem from a misalignment of the transducer with the ship's centerline. Data post-processing included water track calibration of the misalignment angle (0.76° +/- 0.4377°) and scale factor (1.0017 +/- 0.0091) of the Ocean Surveyor signal. The average interval was set to 120 s. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.945842"! ** Velocity quality flagging is based on following threshold criteria: abs(UC) or abs(VC) > 1.3 m/s, rms(UC_z) or rms(VC_z) > 0.3.
