https://www.pangaea.de/ information publisher GEOMAR - Helmholtz Centre for Ocean Research Kiel originator tableDigital Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM88/1 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6 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 1.45 seconds. 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 acquistion 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. The ADCP data were processed using the Python-based DAM-ADCP software, adapted from the OSSI toolbox developed by GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel. The average interval was set to 60 seconds. Data post-processing included water track calibration of the misalignment angle (-47.1499° +/- 0.777°) and the amplitude (1.0106 +/- 0.0144) of the Ocean Surveyor signal. Velocity quality flagging is based on following threshold criteria: abs(UC) or abs(VC) > 2 m/s, rms(UC_z) or rms(VC_z) > 0.3. completed Kopte, Robert
