Raw data of physical oceanography during RV POLARSTERN cruise PS131

Raw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV POLARSTERN during research cruise PS131 (ATWAICE: ATlantic WAter pathways to the ICE). The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD), a CDOM WET Labs ECO-FL fluorometer (FLRTD), a PAR sensor (SeaBird PARLOG) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. The data was recorded using pre-cruise calibration coefficients. No correction, post-cruise calibration or quality control was applied. For the Aurora cast (PS131_075_01), the PAR sensor was removed to include a Seapoint Turbidity Sensor to facilitate the detection of hydrothermal plumes. Independent sensors such as an Underwater Vision Profiler (UVP5 DEEP) and a Lowered ADCP system (RDI LADCP) were attached to the CTD-Rosette system and operated during most of the casts. For all casts shallower than 2000 m a nitrate sensor (Satlantic SUNA) was attached. For data availability see cruise report. A PDF with scans of the handwritten protocols is included in this publication as zip file. The processed dataset will be linked below upon completion.
