    ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM113 (2023)
    PANGAEA
    Details
    Publication Date: 2024-01-26
    Description: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM113 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 8.0 m, while 100 bins were recorded using a pulse of 1.44 s. 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. The ship's velocity was calculated from position fixes obtained by the Global Positioning System (GPS). 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 (0.61° +/- 0.6125°) and scale factor (1.0032 +/- 0.0104) of the Ocean Surveyor signal. The average interval was set to 60 s. Velocity quality flagging is based on following threshold criteria: abs(UC) or abs(VC) 〉 1.5 m/s, rms(UC_z) or rms(VC_z) 〉 0.3.

    Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M154/1 (2021)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: Multibeam bathymetry raw data was recorded in the Atlantic during cruise M154/1 that took place between 2019-04-03 and 2019-04-25. The data was collected using the ship's own Kongsberg EM 122. This data is part of the DAM (German Marine Research Alliance) project Underway Research Data. Sound velocity profiles (SVP) were applied on the data for calibration. SVP data are part of this dataset publication. Please see the cruise report for details.
