Three decades of temperature logging and heat flow determination in Velten [Germany]
Since 1990, the geothermal exploration borehole Gt Velten 2/90 wasrepeatedly logged by GFZ researchers. Several high-precission temperature logs are available, used combined with lab measurements of thermal conductivity on drill cores and estimations from well logs to derive the site heat flow value.
Thermal structure of Tournemire Underground Research Lab (France)
The purpose of this project is the thermal characterization of the Tournemire Underground Research Lab (URL), located in Southern France. This includes in-situ thermal heating experiments, in-situ logging and laboratory test of thermal rock properties. Finally, heat flow is calculated and evaluated.
Thermal characterization of the deep boreholes in Karlshagen, northern Germany
The purpose of this project is the thermal characterization of the deep geothermal boreholes, located in the North German Basin in northern Germany. This includes borehole temperature logging and the determination of thermal rock properties. Finally, heat flow is calculated and evaluated.
Thermal characterization of the deep geothermal boreholes in Schwerin, northern Germany
The purpose of this project is the thermal characterization of the deep geothermal boreholes, located in the North German Basin in northern Germany. This includes borehole temperature logging and the determination of thermal rock properties. Finally, heat flow is calculated and evaluated.
Heat Flow survey in the Ross Sea, Antarctica
This study aims to: Quantify the spatial distribution of heat flow in the Terror Rift System through direct marine measurements. Compare observed values with global analogues to infer the tectonic and magmatic state of the rift. Identify and correct for environmental and geological influences such as past ice sheet dynamics, sedimentation rates, and fluid flow that may bias heat flow observations. Integrate marine data with onshore records and geophysical models to refine the regional thermal framework. Contribute to broader geodynamic, geothermal, and climatic models by improving our understanding of heat transport processes beneath West Antarctica.
