Synonym: Geothermal Temperature Profile = Geotherma
Natural subsurface temperature profile along the True Vertical Direction:
T_G(z), where
z is True Vertical Depth Sub-Sea (TVDss).
It is essentially a true vertical component of local Geothermal Temperature Field
T_G(x, \, y, \, z).
Many subsurface studies are focused on Sedimentary Cover below a specific surface area where lateral \{ x, \, y \} variation of Geothermal Temperature Field T_G(x, \, y, \, z) maybe insignificant comparing to variation along the true vertical direction \{ z \}.
This happens, for example, at the lateral scales of a typical Petroleum Field and allows modelling Geothermal Temperature Field with a laterally constant Geothermal Temperature Profile T_G(z).
The high level overview of Geothermal Temperature Profile in given at Fig 1.
