Depth is the vertical distance below the surface. When the surface temperature is above 0K and there is frozen soil at some point beneath the surface, thawed_soil_depth is the distance from the surface to the first 0K isotherm. When there is no thawed soil layer, the parameter should be reported as missing.

GRIB:

Depth is the vertical distance below the surface. A soil temperature profile may go through one or more local minima or maxima. The "depth at shallowest isotherm" is the depth of the occurrence closest to the soil surface of an isotherm of the temperature specified by a coordinate variable with standard name soil_temperature. [When the surface temperature is above zero degrees Celsius and there is frozen soil at some point beneath the surface, thawed_soil_depth is the distance from the surface to the first 0 degrees Celsius isotherm. When there is no thawed soil layer, the parameter should be reported as missing.]
