This data file contains area-wide soil CO2 flux data from the Escarot mofette area in the Monts Dore volcanic province, Massif Central. Addtional data for stable carbon analysis of CO2 and CH4 as well as noble gas analysis from mofettes are included. Furthermore field parameters (pH, temperature, and electrical conductivity) of an observation borehole and a bubbling mofette are included.

Version history:
4 August 2026: publication of version 2.0.
Changelog:
• Replaced values in table 1, column D 'CO2 flux'. Reason: the processing of data from ppm/sec to g m⁻²d⁻¹ requires, among other things, the air temperature and air pressure. These two parameters had incorrect values and where corrected.
• Added column 'Notes' to table 1.
23 April 2026: release of version 1.0
The data set is a compilation of more than 300 CO2-rich mineral waters and mofettes in the NW Bohemia/Vogtland region. It is a combination of historical data from numerous books and reports, recent scientific papers, as well as own field observations. The oldest literature sources related to these geogenic CO2 gas emissions were mentioned in the 18th century. These springs were famous for their delicious acidic mineral water – so called “Sauerbrunnen” or "Säuerlinge". However, some gas emission sites and their springs dried and disappeared during the centuries, but they were an important meeting point in the villages (water supply) and were therefore mentioned in old geological or historical reports. The coordinates of these former locations could only be estimated. The dataset contains geographic coordinates, Czech and German site names, as well as the location type.
