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 ...
Density is usually calculated using a mathematical function of temperature, salinity, and pressure, sometimes called an equation of state. For many years the internationally accepted...
15 Φεβ 2021 · Monthly Isopycnal & Mixed-layer Ocean Climatology (MIMOC): Animations show pycnocline (temperature and salinity) data of different parts of the world. The NASA animations provide views of how salinity, temperature, and density change over the course of a year.
A T-S diagram shows lines of equal density, or isopycnals, for various combinations of temperature and salinity (Figure 9.8.3). You can then plot the values of temperature and salinity on the diagram, and use their point of intersection to calculate the density of the water.
Definition. 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.
Temperature and salinity control seawater's density. The weight of seawater determines whether it sinks or floats, helping to drive deep ocean circulation. At the sea surface, wind and waves move seawater — and the heat it carries — around our globe.
The general relationship between temperature, salinity and density is illustrated in the figure below. The isopycnals (lines of constant density) are labelled in units of sigma-t, where sigma-t = (density-1000)(kg/m^3). This is a standard oceanographic notation.
