Multiparametric seafloor observatory deployed at the hydrothermal system offshore Panarea island (Aeolian Arc) - PANAREA_SFO

The PANAREA_SFO dataset includes chemical-physical data (temperature, pH, electrical conductivity, dissolved oxygen, pressure), besides the associated sensor metadata, recorded between June 2015 and December 2021 by the PEGASO multiparametric seafloor observatory. The observatory has been deployed over an area marked by an active hydrothermal system at a depth of about 25 meters, two miles off the east coast of Panarea. The target is to perform a long-term monitoring of the marine environment characterized by extreme conditions due to the venting of hydrothermal fluids. The high CO2 flow rate, temperatures up to 140°C, pH less than 3 and electrical conductivity higher than the sea-water, make that site a natural laboratory for a multidisciplinary approach to researchers focused on geohazards, geothermal resources and oceanographic sciences.
