T-S diagram of a station in the North Pacific. In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.In a T-S diagram, rather than plotting each water property as a separate "profile," with pressure or depth as the vertical coordinate, potential temperature (on the vertical axis) is plotted versus salinity (on the horizontal axis).
For example, the water phase diagram has a triple point corresponding to the single temperature and pressure at which solid, liquid, and gaseous water can coexist in a stable equilibrium (273.16 K and a partial vapor pressure of 611.657 Pa). The pressure on a pressure-temperature diagram (such as the water phase diagram shown) is the partial ...
An aerial view of Sellersville in 1894. Sellersville was founded in the early 18th century. It was centered on a major road known as Bethlehem Pike that connected Philadelphia to Bethlehem and the rest of what was then Western Pennsylvania. The town was very small and was called Sellers Tavern. Its most notable feature was a large inn. The ...

The national headquarters for Park Seed Company, Jackson & Perkins, and Wayside Gardens is located in Greenwood, South Carolina. The headquarters complex is surrounded by 9 acres (36,000 m 2) of land that are maintained by the Park Seed Company for many purposes. The trial gardens previously featured on the grounds closed in 2013 as the company ...
Effect of temperature and salinity upon sea water density maximum and sea water freezing temperature. It has long been known that wind can drive ocean currents, but only at the surface. [ 12 ] In the 19th century, some oceanographers suggested that the convection of heat could drive deeper currents.
