The absolute salinity is based on density, where it uses the mass off all non-H 2 O molecules. Conductivity-based salinity is calculated directly from conductivity measurements taken by (for example) buoys. [5] The GSW beta(SA,CT,p) function can calculate β when the absolute salinity (SA), conserved temperature (CT) and the pressure are known.

Temperature and salinity combine to determine the potential density of seawater; contours of constant potential density are often shown in T-S diagrams. Each contour is known as an isopycnal, or a region of constant density. These isopycnals appear curved because of the nonlinearity of the equation of state of seawater.
Annual mean sea surface salinity for the World Ocean. Data from the World Ocean Atlas 2009. [1] International Association for the Physical Sciences of the Oceans (IAPSO) standard seawater. Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is ...
Conservative temperature is defined to be directly proportional to potential enthalpy. It is rescaled to have the same units as the in-situ temperature: = where = 3989.24495292815 J kg −1 K −1 is a reference value of the specific heat capacity, chosen to be as close as possible to the spatial average of the heat capacity over the entire ocean surface.

There may exist proxies for salinity, but to date the main way that salinity has been measured has been by directly measuring chlorinity in pore fluids. [2] Adkins et al. (2002) used pore fluid chlorinity in ODP cores, with the paleo-depth estimated from nearby coral horizons. Chlorinity was measured rather than pure salinity because the major ...
The fraction of brightness temperature to actual temperature is defined as the emissivity. The relationship between brightness temperature and temperature can be written as: = where T b is the brightness temperature, e is the emissivity, and T is the temperature of the surface sea water. The emissivity describes the ability of an object to emit ...
