Which term is a graph showing the relationship of temperature and salinity with depth?

• A. Surface Current
• B. Temperature-salinity (T-S) diagram
• C. Transverse Current
• D. Sverdrup (sv)

Answer: (B)

A temperature-salinity diagram is the chart that shows how temperature and salinity relate to each other for seawater samples, often taken at various depths. This type of plot allows you to see how T and S co-vary as you go deeper and to identify different water masses and mixing between them. Each water mass tends to have a characteristic combination of temperature and salinity, so by graphing T versus S for samples from different depths you can trace their origins and how they blend as depth changes. The other options describe physical ocean features or a unit of measurement rather than a graph of temperature and salinity with depth.
