FTP, name this oceanographic parameter measured relative to a potassium chloride standard according to electrical conductivity, the measure of the dissolved constituents in water.
When calculating this value in situ at conditions other than standard temperature and pressure, it may be helpful to use one of several Lewis-Perkin equations, since these give corrections to the K-sub-fifteen ratio for which it is defined.  Anchialine caves may become stratified with respect to this value, which may create euxinic conditions when combined with anoxia.  At equilibrium, isopycnal diagrams may be generated by equalizing this value with temperature.  Excessive warming and confinement cause it to rise locally, resulting in dense thermohaline currents such as the North Atlantic Deep Current, and this value climaxes at the center of mid-ocean gyres.
