 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.: Geothermal heat flow in Antarctica: current and future directions, The Cryosphere, 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. 

Changes: 
29.07.2020 V002: Database has been updated. Data quality has been revised. New column (10 Elevation) has been added. Two redundancies have been removed.
