Sea surface temperature (SST), or ocean surface temperature, is the water temperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface.
To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat uptake. [14] Between 1971 and 2018, the rise in ocean heat content accounted for over 90% of Earth ...
TEOS-10 (Thermodynamic Equation of Seawater - 2010) is the international standard for the use and calculation of the thermodynamic properties of seawater, humid air and ice. It supersedes the former standard EOS-80 (Equation of State of Seawater 1980). [ 1 ]
Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat ...
In the sun, in the shade, on a rock, in a glade. For every different way there is to experience heat — in the sun, in the shade, on a rock, in a glade — there is a scientific debate about how ...
The dependence on pressure is not significant, since seawater is almost perfectly incompressible. [3] A change in the temperature of the water impacts on the distance between water parcels directly. [clarification needed] When the temperature of the water increases, the distance between water parcels will increase and hence the density will ...
Ocean temperatures at different depths are measured to add to global surface temperature datasets. This data is also used to calculate the ocean heat content . Through 1940, the average annual temperature increased, but was relatively stable between 1940 and 1975.
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.
