" Only in post-processing the nitrate concentrations can be recalculated using the known salinities leading to better precision measurements" this is also true for the SeaExplorer at this time.

I am not sure a standard procedure exists at the DAC level for Nitrates concentrations. However it can be usefull to mention the work conducted by the SOCCOM team (https://soccom.princeton.edu/sites/default/files/files/CWG_white_paper_March_13_2016.pdf ) that propose several methods for RT drift/offset corrections based on :

• knowledge of climatologies (e.g. GLODAP / WOA)

•  stoichiometries between	parameters
  

•   MLR algorithms 
  

•  zero	concentration	in the mixed layer in subtropical regions
  

•  Neural network approaches
