Oxygen saturation

The RBRlegato³ supports the option of integrating the RBRcoda³ T.ODO sensor, which measures oxygen concentration. From this measured value, we derive oxygen saturation using the Garcia and Gordon equation. See Oxygen solubility in seawater: better fitting equations by F. H. Garcia and I. I. Gordon for details. The units of measurement are %.

The Garcia and Gordon equation requires values for absolute temperature (in °K) and salinity, which are derived from measured temperature and conductivity.
