Oxygen saturation
The RBRlegato⁴ supports the option of integrating the RBRcoda 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.
