RSKderiveO2.m

Arguments

Input

 -Required- 

  • RSK 

 -Optional-

  • toDerive - O2 variable to derive, should only be 'saturation' or 'concentration', default is 'concentration'.
  • unit: unit of derived O2 concentration, valid inputs include µmol/l, ml/l and mg/l. Default is µmol/l. Only effective when toDerive is concentration.

Output

  • RSK


This function derives dissolved O2 concentration from measured dissolved O2 saturation using R.F. Weiss (1970), or conversely, derives dissolved O2 saturation from measured dissolved O2 concentration using Garcia and Gordon (1992).  The new oxygen variable is stored in a new column in the data table. 

Example:

CODE
rsk = RSKderiveO2(rsk, 'toDerive','concentration', 'unit', 'ml/l')
