    ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM113 (2023)
    PANGAEA
    Details
    Publication Date: 2024-06-26
    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 MARIA S. MERIAN during cruise MSM113 (2024)
    PANGAEA
    Details
    Publication Date: 2024-06-26
    Description: Raw multibeam bathymetry data were collected aboard RV MARIA S. MERIAN during cruise MSM113 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 09.12.22-12.01.2023 from Las Palmas, Spain to Las Palmas, Spain in the Central Atlantic Ocean. Data were recorded off the NW-African continental margin and West of La Palma. The main aim of MSM113 was to realise an interdisciplinary approach, including a variety of geophysical, geological, geotechnical and oceanographic methods, to study processes that lead to the formation of large fields of sediment waves at the Northwest African margin. Sound velocity profiles (SVP) were applied on the data for calibration. Please see the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Provision of the data is part of the DAM Underway Project.
