3. Results
We applied the BFM and carbonate systems to the Mediterranean 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 offluxes 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.
