Geothermal gradient and heat flow data in and around Japan (I): Appraisal of heat flow from geothermal gradient data [PDF]
Earth, Planets and Space, 2014 We published a CD-ROM “Geothermal Gradient and Heat Flow Data in and around Japan” (Tanaka et al., 2004a), which includes values of heat flow and geothermal gradient data. This compilation was intended to improve the understanding of variations in the thermal regime in and around Japan.

Geothermal gradients in British lake sediments [PDF]
Limnology and Oceanography, 1977 Temperatures have been measured in the water and sediments of Loch Ness and Windermere to investigate the possibility of determining the geothermal heat flow through the bottom of deep British lakes. The accuracy is limited by corrections for annual and long term variations in bottom water temperatures.In Loch Ness (max depth 232 m) the annual ...

Geothermal Gradients and Heat Flow in Norte Basin of Uruguay
International Journal of Terrestrial Heat Flow and Applications, 2020 Progress obtained in a partial update of geothermal gradient and terrestrial heat flow values for the Norte Basin (Uruguay) are presented. It is based on results of temperature measurements carried out in deep water wells. Most of these wells have intersected the southern part of the Guarani Aquifer System, at depths varying from 200 to 1500m.
