We applied the BFM and carbonate systems to the Mediterra- nean Sea under current conditions and aggregated at the level of EEZ as defined in Claus et al. (2013). The results are shown in Table 2 and Figs. 3 and 4. The data are presented both in terms of the total net CO2 flux – which aggregates the value of the physical, solubility and biological pumps – and for the biological pump only. The contribution of the biological pump to the total flux has been estimated running a twin simulation where biological processes have been disabled. The value of the biological pump is calculated by difference between the two simulation runs.
Table 2, Figs. 3 and 5 all refer to the spatial distribution of CO2 fluxes. Fig. 5 depicts the spatial distribution of CO2 fluxes using euro/km2/year as unit. The same figure, after proper rescaling, would illustrate the distribution of fluxes as kg/m2/year. The values over the EEZs can be obtained by integration of CO2 fluxes over the EEZ areas, and can be expressed both as total value over a given EEZ (value of an EEZ), or as normalized values over an area (value of a km2 within a given EEZ). Table 2 gives the list of both the total and the normalized EEZ integrated values expressed as euro, with and
without considering biological processes. Fig. 3 illustrates the total values with and without biological activity.
