Physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV METEOR during research cruise M210. 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 SBE3 temperature and SBE4 conductivity sensor as well as two SBE5 pumps to provide a pumped water supply past each sensor. Additionally, a single SBE43 oxygen sensor is attached.
