Literature Review
The Global Heat Flow Database (GHFDB) is committed to maintaining the highest standards of data quality. To achieve this, we have implemented a rigorous literature review process that ensures all datasets are thoroughly vetted before being made publicly available.

Preliminary investigations of rock conductivity and terrestrial heat flow in southeastern Michigan
Heat flow and depth of permafrost at Resolute Bay, Cornwallis Island, N. W. T., Canada
The program of diamond drilling carried out by the Dominion Observatory and the Meteorological Division, Department of Transport at Resolute Bay during the summers of 1950 to 1953 permitted the placing of thermistors at various intervals to a maximum depth of 650 ft. The thermal conductivity of core samples was determined by the divided-bar method. The average conductivity combined with the high reciprocal gradient (25.4 m/°C) give a value of the heat flow toward the surface of 2.9 ± 0.4 ? 10?6 calories cm?2 sec?1. Extrapolation of the temperature versus depth graph indicates that the permanently frozen region extends to …

Heat flow at Kirkland Lake
This is the first of a series of papers on heat flow in the Canadian Shield. The flow depends upon thermal conductivity and temperature gradient. The latter has been measured for the Kirkland Lake region by Misener who obtained a value of 0.0130°C/meter from many measurements in three local mines, extending over a length of two miles and depths of 7500 ft. The conductivities of specimens from the same points have been measured in the laboratory with an average value of 76.7 ± 1.0 × 10-4 cal/cm sec °C, resulting in a surface heat flow of 1.00 ± 0.02 cal/cm2 …
Heat Flow through the Floor of the Eastern North Pacific Ocean
THE flow of heat through the earth's crust has been measured many times at various continental locations, and is usually found to lie1 within 50 per cent of 1.2 × 10−6 cal. cm.−2 sec.−1. Because of the absence of granitic rocks, with their relatively high radioactivity, in the crust under the oceans, it has been suggested that the heat flow through the deep-sea floor might be considerably smaller; but the only data available from oceanic areas have been two measurements of the thermal gradient in deep-sea sediments reported by Pettersson from the Swedish Albatross expedition2.
TEMPERATURE GRADIENT IN THE SOUTH-LIMBURG COAL FIELD (THE NETHERLANDS)
Terrestrial heat flow in Ontario and Quebec
From some 1000 measurements of true rock temperatures, correct to 0.1°F, made at various depths in eight regions of Ontario and Quebec, average vertical temperature gradients for each location were obtained. Thermal conductivity measurements involving the preparation of approximately 300 rock specimens collected near the points of temperature measurement were carried out using the divided-bar method. The terrestrial heat flow was computed for each region. The values obtained lie between 0.69 ? 10?6 and 1.05 ? 10?6 cal/cm2/sec. Statistical analysis and rejection criteria were employed to determine the best values and probable errors of the calculated heat flows. It was …
