The dataset includes a measured device temperature channel and the oxygen saturation values [%] computed from concentration and temperature.</p> <p><b>Purpose:</b> The sensor is used to monitor the oxygen concentration dissolved in sea water and to provide oxygen concentration values needed by the methane sensor calibration formula.</p> <p><b>Quality of data:</b> Raw Oxygen data as recorded by the Optode sensor from 5 October 2009 until 15 March 2010. The data set is continuous with few gaps (0.048% samples lost). The concentration values are not corrected for sea salinity. True concentration values needs post processing elaboration using salinity data [see Optode manual]. The temperature channel measures the device temperature.</p>
