Monitoring of the CO2 natural baseline levels at the seafloor

The Environment and Sustainable Development Department of ERSE SpA is carrying out activities on geological storage of CO2 in Italy (Research Fund for Electric System-CO2 Sequestration Project). In this work, the experimental approach and set-up facing the monitoring of the natural baseline levels of CO2 at the sediment-water interface is described. In particular, the characteristics of a sampling system, based on use of a benthic chamber, and of an analytical system, based on a flow analysis technique coupled with a micro-conductometric cell, are described. This experimental approach was adopted in a cruise carried out, last year, in a coastal area of the Middle Adriatic Sea. Preliminary results of the natural baseline fluxes of the four parameters of the carbonate system are reported.
