Combs, J

Heat flow studies in the Coso Geothermal Area were conducted at China Lake, California. Temperature measurements were completed in nine of the heat flow boreholes. Temperatures were measured at five meter intervals from the ground surface to the deepest five meter interval. Subsequently, temperatures were remeasured two or three times in each borehole in order to demonstrate that equilibrium thermal conditions existed. The maximum difference in temperature, at any of the five meter intervals, was 0.03 deg C. Results from these boreholes, as well as from the other seven, indicate that the temperature data above 15 meters is useless for calculating the geothermal gradients. This is due to the effects of solar radiation at the surface of the earth.
