Figure 8From: Water-air CO2 fluxes in the Tagus estuary plume (Portugal) during two distinct winter episodes Surface concentration of monitored properties. Characterization of the Tagus coastal area during March 2001 and February 2004. Surface concentration of (A,F) silicate (Si(OH)4), (B,G) suspended matter (SPM), (C,H) chlorophyll a (Chl a), (D,I) dissolved oxygen (DO), and (E,J) calculated CO2 partial pressure (pCO2).Back to article page
