We report first data on chemical composition of the gasemitted by the geothermal system of Sousaki, Greece. Gasmanifestations display typical geothermal gas compositionwith CO2 as the main component and CH4 and H2S asminor species. Soil gas composition derives from themixing of two end-members (atmospheric air andgeothermal gas). Soil CO2 fluxes range from<2 to33,400 g m2 d1. The estimated diffuse output ofhydrothermal CO2, estimated for an area of 0.015 km2, isabout 630 g s1, while a tentative estimation of CH4 diffuseoutput gave a value of about 1.15 g s1
