Abstract:
Physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV MARIA S. MERIAN during research cruise MSM105. 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.

Comment:
The date/time, latitude and longitude information came with the CTD measurements. Unfortunately, the longitude information is incomplete. Therefore, the geocode information from the events have been added to the data table. The event geocode is usually logged when the CTD is at maximum depth in the water. Therefore, geocode information from the CTD system and the CTD event might vary.
