    Continuous thermosalinograph oceanography along RV METEOR cruise track M161 (2022)
    PANGAEA
    Details
    Publication Date: 2024-02-16
    Description: Underway temperature and salinity data was collected along the cruise track with two autonomous thermosalinograph (TSG) systems, each consisting of a SBE21 TSG together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. No calibration for temperature and salinity was performed. For details to all processing steps see Data Processing Report.

    Shipboard ADCP current measurements (75 kHz) during RV METEOR cruise M189/2 (2023)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: Current velocities of the upper water column along the cruise track of R/V Meteor III cruise MET189_2 were collected by a vessel-mounted 75 kHz RDI Ocean Surveyor ADCP. The ADCP transducer was located at 5.0 m below the water line. The instrument was operated in narrowband mode (WM10) with a bin size of 8.00 m, a blanking distance of 4.00 m, and a total of 100 bins, covering the depth range between 17.0 m and 809.0 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. 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 (0.0202° +/- 0.5889°) and scale factor (1.0037 +/- 0.0135) 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 following threshold criteria: abs(UC) or abs(VC) 〉 1.5 m/s, rms(UC_z) or rms(VC_z) 〉 0.3.

    Shipboard ADCP current measurements (38 kHz) during RV METEOR cruise M189/2 (2023)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: Current velocities of the upper water column along the cruise track of R/V Meteor III cruise MET189_2 were collected by a vessel-mounted 38 kHz RDI Ocean Surveyor ADCP. The ADCP transducer was located at 5.0 m below the water line. The instrument was operated in narrowband mode (WM10) with a bin size of 16.00 m, a blanking distance of 8.00 m, and a total of 80 bins, covering the depth range between 29.0 m and 1293.0 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. Measured velocities and bin-depth mapping were corrected due to occasional incorrect temperature measurements at the transducer that affected the sound velocity calculation. Corrected sound velocity values were derived using temperature measured by the ship's thermosalinograph. 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 (-44.9032° +/- 0.5594°) and scale factor (1.0036 +/- 0.0116) of the Ocean Surveyor signal. The velocity data were averaged in time using an average interval of 60 s.

    Multibeam bathymetry processed data (Kongsberg EM 122 transit dataset, Generic sensor format) of RV MARIA S. MERIAN during cruise MSM79/2, Atlantic Ocean (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The multibeam echo sounder (MBES) data was collected from the 07.12.2018 (16:34 UTC) to the 13.12.2018 (10:34 UTC) with the Kongsberg EM122 on RV Maria S. Merian during the transit from Mindelo (Capo Verde) to Bahia de las Minas (Panama) in the Atlantic Ocean (MSM79/2). The deep-water MBES EM122 operates with an acoustic frequency of 12 kHz and a beam opening angle of 2° x 2°. The raw and unprocessed bathymetric and backscatter data is stored in Kongsberg format (*.all), each containing up to 60 min of data. The therein included time, motion and position data (WGS84, geographic) was measured by the Kongsberg Seapath system on board. During the acquisition the echo sounder was monitored as well as settings and filter adjusted according to the environment. The swath opening angle was set to 65° and the travieling speed was about 10 - 13 kn. As the data was collected during transit, no specific survey was performed. A sound velocity profile acquired during a previous cruise was applied in the MBES acquisition software SIS. The SVP data is not part of this submission. The data was post-processed using the software QPS Qimera. No further SVP re-computation, navigation correction or tide correction was applied. Erroneous depth measurements were deleted manually by using the swath and slice editor. The vertical datum is mean sea level (MSL). The cleaned data was exported in gsf format.
