Within Vocab BODC parameter semantic model data processing entity descriptions
Preferred Label calibration to read zero in clear water
Definition A correction has been made to the data for light source deterioration using a procedure that results in a zero value in pure water, rather than a zero value in air (which would give a value in pure water of around 0.36).
