Chemical-physical and dissolved gases in Etnean groundwater: data from Ponteferro drainage gallery (Santa Venerina - CT)

Groundwater chemical-physical data in the drainage gallery (Ponteferro gallery – Santa Venerina, CT) located east of the Etna volcano (May 2005-Dec 2018), belonging to the Etna geochemical surveillance network of the Istituto Nazionale di Geofisica e Vulcanologia (INGV). Data have been acquired by a water station equipped with multiparameter sensors. Dissolved CO2 (CO2c) has been re-calculated by mean of an algorithm (De Gregorio et al. 2011) using the raw data (CO2_0 and CO2_1).
