temperature-salinity diagram

[′tem·prə·chər sə′lin·əd·ē ‚dī·ə‚gram] (oceanography) The plot of temperature versus salinity data of a water column; the resulting diagram identifies the water masses within the column, the column's stability, indicates the σT value via lines of constant σT printed on paper, and allows an estimate of the accuracy of the temperature and salinity measurements. Also known as T-S curve; T-S diagram; T-S relation.
