Underway data for dissolved oxygen, total dissolved gas pressure, fluorescence and turbidity have been collected along the track of the RV METEOR cruise M160 around the Cape Verde archipelago. Water was pumped from the moon pool at 5 m depth into an insulated box, where the sensors were located. Discrete samples for dissolved oxygen were taken from the water stream and analysed on board by Winkler titration to correct the sensor data. Salinity data used for corrections and conversions was taken from the shipside TSG measurements at 5m depth.

Continuos sensor data for dissolved oxygen, total dissolved gas pressure, fluorescence and turbidity. While the dissolved oxygen data was corrected using discrete winkler titration samples taken from the same water stream, fluorescence an turbidity values are given in arbitrary units, as the sensor was not calibrated. No specific data correction was applied to the total dissolved gas pressure values, as the sensor is not known to drift.
