• Optimize the grid size

• Find appropriate statistical model(s) to analyse the variance

Example: ±10 µatm ±0.14 mol m-2 yr-1, or 11% of the annual flux

Future work: January to June 2007

Implement the CO2 module in the 3D-MIRO&CO Model (Lacroix et al., 2005) Simulations for the present-day period validated with ULg pCO2 data base Map regional sources and sinks of CO2 for different seasons and years and identify the controlling mechanisms

Geographical domain of the 3D-MIRO&CO

Future work-2007

Thermogravimetry (TG) + IR – useful tool to distinguish labile (L) and stabile (S) organic matter fractions in sediments. S – L = Return flux. The images show a 3D TG/IR of sedimentary OM

WP13: CO2 EXCHANGE BETWEEN WESTERN MEDITERRANEAN AND ATLANTIC OCEAN. FUTURE WORK

-Five more seasonal cruises will be performed in the Strait of Gibraltar during2007 on board the Moroccan RV Al Amir Moulay Abdallah.

March May September December

-Generation of a data sets from 3 cruises and a VOS line using Spanish ships in order to consolidate a permanent Timeseries (GIFT: Gibraltar Fixed Timeseries).

-Evolution of carbon fluxes through the Strait of Gibraltar.

WP14

Set of emission/discharge factors for future releases of other carbon-containing GHGs (CH4) – scenarios to 2030

presently scenarios for whole Europe and Russia based on EEA projections for GHGs (database and reports) are ready,

additional data will be searched

analysis of main sources will be provided

Inversion modeling of European carbon balance
