Continuous thermosalinograph oceanography along RV MARIA S. MERIAN cruise track MSM104

Karin A F Zonneveld & Michael Schlundt
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 12 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. No calibration was done for temperature and salinity. For details to all processing steps see Data Processing Report.

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

Karin A F Zonneveld & Robert Kopte
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...

ADCP current measurements (38 kHz) during RV MARIA S. MERIAN cruise MSM104

Karin A F Zonneveld & Robert Kopte
Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM104 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 broadband mode with 32 m bins and a blanking distance of 16.0 m, while 50 bins were recorded using a pulse of 1.65 s. The ship's velocity was calculated from position fixes obtained...

Continuous thermosalinograph oceanography along RV Maria S. Merian cruise MSM98

Miriam Römer & Michael Schlundt
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 12 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. Salinity was calibrated independently for both measurement containers (MCs). No correction was done for temperature. For details to all processing steps see Data Processing Report.

Seabed photographs and videos taken with ROV MARUM-Quest dive453 during R/V SONNE cruise SO273

Jürgen Koepke, Volker Ratmeyer & Marcel Schröder
The primary aim of the project Marion Rise, which is an international program between scientists from Germany, United States and China, was to explore and sample two main working areas along the Southwest Indian Ridge in the southern Indian Ocean. The research program of expedition SO273 Marion Rise had the main objective of sampling rocks and fluids and mapping segments of the slow spreading Southwest Indian Ridge (SWIR) near Marion Island. The Northern working area...
