    Shipboard ADCP current measurements (38 kHz) during RV SONNE cruise SO299 (2024)
    PANGAEA
    Details
    Publication Date: 2024-04-03
    Description: Current velocities of the upper water column along the cruise track of R/V Sonne cruise SO299 were collected by a vessel-mounted 38 kHz RDI Ocean Surveyor ADCP. The ADCP transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode (WM10) with a bin size of 32.00 m, a blanking distance of 16.00 m, and a total of 50 bins, covering the depth range between 54.0 m and 1622.0 m. Heading, pitch and roll data from the ship's motion reference unit and the navigation data from the Global Positioning systems were used by the data acquisition software VmDAS internally to convert ADCP velocities into earth coordinates. Single-ping data were screened for bottom signals and, where appropriate, a bottom mask was manually processed. 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 (-0.2374° +/- 0.5601°) and scale factor (1.0045 +/- 0.0097) of the Ocean Surveyor signal. The velocity data were averaged in time using an average interval of 60 s. Velocity quality flagging is based on different threshold criteria: Depth cells with ensemble-averaged percent-good values below 25% are marked as 'bad data'. Depth cells with velocities above 1.5 m/s are flagged as 'bad data'. Depth cells with a root-mean-square deviation between the measured ensemble-average velocity and a cell-wise running-mean velocity above 0.3 m/s are flagged as 'probably bad data'.

    Effects of the hydrous domain in the mantle wedge on magma formation and mixing at the Northeast Lau Spreading Centre, SW Pacific (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-12
    Description: Major and trace element concentrations of young volcanic rocks from the Northeast Lau Basin in the SW Pacific Ocean, as well as Sr-Nd-Hf-Pb isotope compositions. Analyses were mainly carried out at the GeoZentrum Nordbayern, University of Erlangen, Germany, where major elements were determined by electrons microprobe on volcanic glasses and by XRF on whole rocks. Trace elements were analyzed by LA ICPMS on glass at the Macquarie University, Sydney, Australia, and by dissolution ICPMS at the GeoZentrum Nordbayern. Water concentrations on glasses were analyzed by SIMS at the Australian National University, Canberra, Australia. Isotope ratios were determined by TIMS and MC ICPMS at the GeoZentrum Nordbayern.
