Consider an RBRconcerto C.T.D.DO logger, where the DO channel is a RBRoptode. The RBRoptode transfers both the foil temperature and the dissolved oxygen concentration (not compensated for salinity). The RBRconcerto calculates the concentration compensated for salinity first, then the air saturation (in %) via the following equation:
Where Cc is the concentration in uMol/L, compensated for salinity.
Solubility is calculated via Gordon and Garcia as:
where S is the salinity in PSU and Ts is defined as:
with T being the water temperature in °C and:
Air vapor pressure (in dbar) is calculated via :
The n-coefficients in the logger equation correspond to the following:
Example commands:
>> calibration 9 type << calibration 9 type = doxy22 |
( Confirm the channel type )
>> calibration 9 |
( Request confirmation of everything )
