A classical, and highly productive, approach to studying hydrographic data in the ocean is to use T–S (Temperature–Salinity) analysis. This is a convenient methodology that allows definition of water mass types and quantification of mixing. Information about temperature, salinity and pressure (depth) can further be used to calculate the water’s density...
