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 O₂concentration 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')
