Synonym: Geothermal Temperature Profile = Geotherma
Natural subsurface temperature profile along the True Vertical Direction:
, where is True Vertical Depth Sub-Sea (TVDss).
It is essentially a true vertical component of local Geothermal Temperature Field .
Many subsurface studies are focused on rocks below on Sedimentary Cover below a specific surface area where lateral ( LaTeX Math Inline |

) variation variation of Geothermal Temperature Field maybe insignificant comparing to to variation along the true vertical direction ( LaTeX Math Inline |

) variation.
This allows using 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 instead of Geothermal Temperature Field .
.
The high level overview of the Earth's Geothermal Temperature Profile is brought at Fig 1.
The zoomed picture of a typical Geothermal Temperature Profile in Sedimentary Cover of the Earth's Crust is brought at Fig 2.
Impact from Surface Temperature Variations
The surface temperature variations penetrate the Sedimentary Cover all the way down to the Neutral Temperature Layer (NTL) (see Fig. 3) which varies from few meters to few dozens of meters.
An imaginary subsurface temperature profile under assumption of the constant surface temperature is called Unbiased Geothermal Temperature Profile LaTeX Math Inline |
