title: Shipboard ADCP current measurements (38 kHz) during RV METEOR cruise M205

description: Current velocities of the upper water column along the cruise track of R/V Meteor cruise M205 were collected by a vessel-mounted 38 kHz RDI Ocean Surveyor ADCP. The expedition M205 was made possible through funding for the RUBBLE project from the German Research Foundation (DFG) and the Federal Ministry of Education and Research (BMBF) under grant no. GPF 21-1_060. 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. Attitude data from the ship's motion reference unit were used by the data acquisition software VmDAS internally to convert ADCP beam velocities to geographic coordinates. The Python toolbox OSADCP (version 2.0.2) was used for data post-processing. Acoustic Interferences were identified based on outliers in the ADCP echo intensity data. Echo intensity data were cleaned accordingly and affected velocity cells were flagged to be removed prior ensemble-averaging. The ship's velocity was calculated from position fixes obtained by the Global Navigation Satellite System (GNSS), taking into account lever arms of ADCP transducer and GNSS antenna. Accuracy of the derived water 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 processing included water track calibration of the misalignment angle (0.1606° +/- 0.3993°) and scale factor (1.0044 +/- 0.0076) of the measured velocities. The velocity data were averaged in time using an average interval of 60 s. Depth cells with ensemble-averaged percent-good values below 25% are marked as 'bad data'.

title: Continuous thermosalinograph oceanography along RV ALKOR cruise track AL618

description: Underway temperature and salinity data was collected along the cruise track with a thermosalinograph (TSG) together with a SBE38 Thermometer. Both systems worked throughout the cruise. While temperature is taken at the water inlet in about 4 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. No temperature calibration was performed. Salinity was calibrated with independent water samples taken at the water inlet. For details to all processing steps see Data Processing Report.
description: Salinity was calibrated independently with water samples from 4m depth (tim is the time in days since Expocode of this cruise (06AK20240818), i.e. since 2024-08-18T00:00:00): Value added to salinity data = -0.0038328*tim+0.14874.Version 2, 2025-04-25: Previous version doi:974225 contains errors.

title: ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM104

description: Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM104 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 broadband mode with 16 m bins and a blanking distance of 8.0 m, while 50 bins were recorded using a pulse of 0.82 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 (0.78° +/- 0.6134°) and scale factor (1.0133 +/- 0.0100) of the Ocean Surveyor signal. The average interval was set to 120 s.

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M207

description: Raw multibeam bathymetry data were collected aboard RV METEOR during cruise M207 using a 12kHz Kongsberg EM 122 multibeam echosounder. The expedition took place during 2025-01-05 – 2025-02-11 from Belem (Brazil) to Mindelo (Cape Verde) in the Central Atlantic. The major aims of M207 are to investigate the variability of the western boundary current circulation off South America and to contribute to the assessment of the variability of the Atlantic Meridional Overturning Circulation (AMOC) at 11S. Data were recorded within the EEZ of Brazil as well as outside EEZs. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and 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. Data acquisition was done by GEOMAR Helmholtz Centre for Ocean Research, provision of the data is supported by the DAM Project Underway Research Data and published according to the FAIR principles.
