Fig. 2.

Diurnal variations of geochemical parameters for 19 to 20 July 2003. The x axis labels are common to all of the panels; the dashed lines represent atmospheric CO2 partial pressure and 100% atmospheric O2 saturation value; shadowed areas denote the night. DO, dissolved oxygen; EC, electrical conductivity; TDS, total dissolved solids; TP, total phosphorus.
