Database for Antarctic Geothermal Heat Flow
This database aims to collect and distribute geothermal heat flow estimates south of 50° and accompanies the following manuscript:
Burton-Johnson, A., Dziadek, R. and Martin, C.: Review Article: Geothermal heat flow in Antarctica: current and future directions, The Cryosphere, 14, 3843–3873, doi:https://doi.org/10.5194/tc-14-3843-2020, 2020.
When using the database we kindly ask you to cite this publication.
The data is stored in a comma-separated format as a .xlsx file and contains 15 columns:
(1) Latitude: in decimal degrees (DD.xxx)
(2) Longitude: in decimal degrees (DD.xxx)
(3) StationID: Station Name/identifies (if given)
(4) top (m): minimum depth of measurement in meters
(5) bottom (m): maximum depth of measurement in meters
(6) grad (°C/km): Geothermal gradient
(7) Thermal conductivity: if given in Watt-per-Meter-per-Kelvin (Wm/K)
(8) geothermal heat flow: in Milliwatts-per-square-Meter (mW/m²)
(9) Error: in Milliwatts-per-square-Meter (mW/m²)
(10) Elevation in meters above sea level (m.a.s.l.)
(11) Reference: 1st Author and Year of publication
(12) DOI: Digital Object Identifier or link to original study
(13) DataQuality: Attempt to describe quality of measurements (Grade *1 = Lowest reliability, *2 = Intermediate reliability, *3 = Highest reliability). For details see file: Data Quality Evaluation.pdf
(14) Method: Indicates type of estimate
(15) Comment: Contains additional information
Please consider, that this database might be subject to updates.
