Chemical-physical and dissolved gases in Etnean groundwater: data from Roccacampana drainage gallery (Piedimonte Etneo- CT)

Groundwater chemical-physical data in the drainage gallery (Roccacampana gallery – Piedimonte Etneo, (CT) located northest of the Etna volcano (Oct 2009-Dec 2018), belonging to the Etna geochemical surveillance network of the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The monitored groundwater intercepts the Pernicana Fault, along which degassing related to volcano-tectonic activity is observed. 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).
