Physical oceanography during RV MARIA S. MERIAN cruise MSM107
No full textPhysical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV MARIA S. MERIAN during research cruise MSM107. The CTD system is comprised of a Seabird SBE911plus including dual respectively redundant sensor and pump packages. The SBE11plus Deck Unit remains on board in a laboratory and supplies on one hand power to the SBE9plus underwater unit, on the other hand data telemetry between the SBE9plus and a measurement PC. The SBE9plus underwater unit itself holds a pressure sensor and is interfacing with dual SEB3 temperature, SBE4 conductivity and SBE43 oxygen sensors and two SBE5 pumps to provide a pumped water supply past each sensor. The system also carries an optical FLNTU sensor to measure a combinations of back-scattering, turbidity, and chlorophyll-a. To quantify the photo-synthetically active radiation a PAR sensor is installed as well

ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM107
No full textUpper-ocean velocities along the cruise track of Maria S. Merian cruise MSM107 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 1.42 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 (0.61° +/- 0.8098°) and scale factor (0.9987 +/- 0.0117) 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

ADCP current measurements (38 kHz) during RV MARIA S. MERIAN cruise MSM107
No full textUpper-ocean velocities along the cruise track of Maria S. Merian cruise MSM107 were continuously collected by a vessel-mounted Teledyne RD Instruments 38 kHz Ocean Surveyor ADCP.
The transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode with 32 m bins and a blanking distance of 16.0 m, while 50 bins were recorded using a pulse of 2.85 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 (0.34° +/- 0.9292°) and scale factor (0.9996 +/- 0.0145) 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

Water column raw data (Kongsberg EM712 entire dataset) of RV MARIA S. MERIAN during cruise MSM107
No full textRaw multibeam water column data were collected aboard RV MARIA S. MERIAN during cruise MSM107 using a Kongsberg EM 712 multibeam echosounder. The expedition took place during 18.05.2022 and 03.06.2022 from Bremerhaven (Germany) - Tromsø (Norway) in the Northern Atlantic Ocean. Data were recorded 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. The main aim of MSM107 was to study organic matter formation, transport and transformation on and off the western Irish shelf. The research is part of a larger research project to quantify the contribution from shelf production to deep ocean carbon storage. Acquisition and provision of the data are part of the DAM Underway Project
