Definition	This group contains the state variable parameters pertaining to carbon, nitrogen and phosphorus that do not obviously belong in other groupings. Consequently, this grouping should be considered as an 'others' category and its contents should be periodically reviewed with a view to the creation of additional groupings should this be deemed necessary. In the case of carbon, parameters are split between this grouping and the Carbonate System APG. The latter are clearly defined and this group contains anything that is left. Current (May 2003) carbon parameters in this grouping from the BODC Parameter Dictionary include: Measurements of the calcite concentration in the water column expressed in terms of carbon concentration per unit volume/mass of water. Particulate organic (or total) carbon concentration. Dissolved organic carbon concentration. Total, organic and/or inorganic carbon content (mass carbon per unit mass of substrate) of sediment or suspended particulate material. For nitrogen, the parameters are split between this APG and Nutrients. Again, the latter is more clearly defined, leaving the rest for this grouping. Current (May 2003) nitrogen parameters in this grouping from the BODC Parameter Dictionary include: Particulate nitrogen ("PON") concentration. Dissolved total nitrogen. Nitrogen content of sediment. For phosphorus, the parameters are again split between this APG and Nutrients, which is the more clearly defined. Current (May 2003) phosphorus parameters in this grouping from the BODC Parameter Dictionary include: Particulate total and organic phosphorus concentration. Dissolved total phosphorus. Phosphorus content of sediment or SPM.
