Gas geochemistry at Panarea shallow CO2 seeps during ECO2-2 cruise

Geochemical parameters were measured at two CO2 sites and one non-CO2-impacted site near the island of Panarea (Italy). All sites were located between ~15 and 20 m water depth at a temperature of 19°C. Gas samples were obtained for both CO2 sites. Sulphide was not detected (qualitatively). Detection limit for methane was 500 ppm.
