The average salinity of seawater is S = 35 which means that SW is 3.5% salt and 96.5% H2O by weight. Why is salinity important? 1. Salinity, along with temperature, determines the density of seawater, and hence its vertical flow patterns in thermohaline circulation. 2. Salinity records the physical processes affecting a water mass when it was ...
What do oceanographers measure in the ocean? What are temperature and salinity and how are they defined?

Key Ideas. Ocean water circulates in currents. Surface currents are driven by wind and affect the uppermost 10% of the ocean. Circulation of the other 90% of the ocean is driven by gravity, as dense water sinks and less dense water rises.
T-S diagrams are graphic representations of two main properties of water masses: Temperature and salinity. Usually, the salinity is plotted on the X-axis and the temperature on the Y-axis. Those two properties are the main factors of a third one, the density. The latter is thus also represented on the graph by addition of curves of equal ...
lists the basic concepts and formulae of equilibrium thermodynamics, vector and tensor analysis, curvilinear coordinate systems, and the kinematics of fluid flows and waves.
Temperature, Salinity, and Density. Insolation, evaporation, and rain influence the distribution of temperature and salinity at the ocean’s surface. Changes in temperature and salinity lead to changes in the density of water at the surface, which can lead to convection and changes in the deeper circulation of the ocean.
