Popis: article i nfo The Salton Sea Geothermal System (California) is an easily accessible setting for investigating the interactions of biotic and abiogenic geochemical processes in sediment-hosted hydrothermal systems. We present new temperature data and the molecular and isotopic composition of fluids seeping at the Davis-Schrimpf seep field during 2003-2008. Additionally, we show the first flux data for CO2 and CH4 released throughout the field from focused vents and diffuse soil degassing. The emitted gases are dominated by CO2 (~98%) and CH4 (~1.5%). By combining δ 13 CCO2 (as low as �5.4‰)
