Review of “Technical note: TEOS-10 EXCEL – Implementation of the Thermodynamic Equation Of Seawater – 2010 in EXCEL” by Carlos Gil Martins and Jaimie Cross This technical note describes the implementation of TEOS-10 software in Excel Most of the software implemented is from the GSW toolbox (McDougall and Barker 2011)
Seawater density is illustrated in the diagram by curved lines of constant density Surface waters are mixed by winds and deep ocean water mixing is driven by density differences Circulation in the depths of the ocean is referred to as thermohaline circulation
What are 2 main factors determine the density of seawater?
Seawater density varies with temperature, degree of salinity, and depth. High temperature produces low density, and high salinity produces high density. Deep water has high density because of low temperature and because of the pressure of the overlying water.
What affects the density of seawater?
The density of seawater depends on temperature and salinity. Higher temperatures decrease the density of seawater, while higher salinity increases the density of seawater. The following figure shows how density is affected by temperature and salinity. The lines through the figure are lines of constant density.
What is the density in seawater determined by?
density of seawater is determined by both salinity and temperature. The saltier the denser, and the warmer the lighter. Saltier water is denser than fresher water because the dissolved salts ?ll interstices between water molecules, resulting in more mass per unit volume. Warmer seawater expands and is thus less dense than cooler seawater. It thus
