    Microstructure measurements during METEOR cruise M106 (2020)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: 118 profiles of post-processed upper-ocean microstructure data from a loosely-tethered profiler (MSS90-D, manufactured by Sea & Sun Technology) collected in the central and western tropical Atlantic. Dissipation rates of turbulent kinetic energy are calculated as described in Schafstall et al. (Journal of Geophysical Research, 2010). Stored parameters include: Dissipation rate of turbulent kinetic energy in m^2 s^(-3) from 3 microstructure shear sensors, temperature, salinity and depth.

    ADCP current measurements (38 kHz) during RV METEOR cruise M182 (2022)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: Upper-ocean velocities along the cruise track of RV METEOR cruise M182 were continuously collected by a vessel-mounted Teledyne RD Instruments 38 kHz Ocean Surveyor ADCP. The transducer was located at 5.0 m below the water line. The instrument was operated in broadband mode with 16 m bins and a blanking distance of 8.0 m, while 100 bins were recorded using a pulse of 1.65 s. 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 acquisition 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. Data post-processing included water track calibration of the misalignment angle (-0.19° +/- 0.4864°) and scale factor (1.0049 +/- 0.0086) of the Ocean Surveyor signal. The average interval was set to 60 s.

    ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM106 (2022)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM106 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 three different configurations: 1) broadband mode with 4 m bins and a blanking distance of 2.0 m, with a total of 128 bins, 2) broadband mode with 8 m bins and a blanking distance of 4.0 m, with a total of 100 bins, 3) narrowband mode with 8 m bins and a blanking distance of 4.0 m, with a total of 100 bins. 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 acquisition 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. Data post-processing included water track calibration of the misalignment angle (configuration 1: 0.65° +/- 0.5915°, configuration 2: 0.78° +/- 0.5198°, configuration 3: 0.67° +/- 0.6996°) and scale factor (configuration1: 1.0075 +/- 0.0117, configuration 2: 1.0075 +/- 0.0087, configuration 3: 1.0007 +/- 0.0157) of the Ocean Surveyor signal.

    Shipboard ADCP current measurements (38 kHz) during RV MARIA S. MERIAN cruise MSM117 (2024)
    PANGAEA
    Details
    Publication Date: 2024-02-08
    Description: Current velocities of the upper water column along the cruise track of R/V Maria S. Merian cruise MSM117 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 two different configurations: 1) broadband mode with 32 m bins and a blanking distance of 16 m, with a total of 50 bins, 2) narrowband mode with 32 m bins and a blanking distance of 16 m, with a total of 50 bins. Beam velocities as recorded by the data acquistion software VmDAS were transformed to ship coordinates and after merging with the navigation data from the ship's Motion Reference Unit and Global Positioning systems 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 (configuration 1: 0.3196° +/- 0.8714°, configuration 2: 0.3603° +/- 0.6433°) and scale factor (configuration1: 1.0007 +/- 0.0151, configuration 2: 1.0024 +/- 0.0107) 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) 〉 2.0 m/s, rms(UC_z) or rms(VC_z) 〉 0.3.

    Synoptic upper-ocean mixing events in the tropical Atlantic for evaluating Earth system models (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: Observational and modelling studies of the mixed layer heat balance in the tropical Atlantic have demonstrated the importance of vertical turbulent mixing for generating seasonal cooling of sea surface temperature (SST) (e.g. https://doi.org/10.3389/fmars.2019.00206). Progress has been made identifying processes responsible for the seasonal cycle of vertical turbulent mixing such as shear from the background currents, intraseasonal variability and wind-driven waves. Here, we used an extensive observational mixing data base from the tropical Atlantic to compile average synoptic scale upper-ocean mixing events and associated heat and momentum fluxes as well as oceanic background parameters. It provides the vertical distribution of upper-ocean turbulence during three separable physical processes that are known to play a key role in controlling the sea surface temperatures in the tropical oceans 1) near-inertial waves 2) Tropical Instability Waves 3) equatorial mixing driven by vertical shear of equatorial currents. The data sets provided can be used to evaluate the vertical mixing schemes of Earth system models and ocean general circulation models.
