Definition	This group contains parameter codes describing the concentrations of the substances that provide the essential basic elements - nitrogen, phosphorus and silicon - to the phytoplankton. The species covered are: Nitrogen - nitrate, nitrite, ammonium and urea. Phosphorus - orthophosphate Silicon - hydrosilicic acid, commonly termed 'silicate'. The grouping also covers uncalibrated analytical or in-situ instrument outputs, such as monochromatic optical absorbances at the appropriate wavelengths for nutrient determination.
