The volume of Caribbean Sea water in bivariate classes of potential temperature vs. salinity has been estimated from 76 hydrographic stations. The resulting statistics are presented on a pair of characteristic diagrams. The outstanding feature of the diagrams is the strong mode; nearly half of all Caribbean water lies within 0.1°C and 0.02 per mil of the mode, at 3.9°C, 34.98 per mil....
