Fig. 5: Relation between the photosynthetic efficiency (Fv/Fm) and dissolved trace metals (dFe and dMn).

From: Iron and manganese co-limit the growth of two phytoplankton groups dominant at two locations of the Drake Passage

Fig. 5

Linear regression (red line) between Fv/Fm and a the concentrations of total dissolved iron (dFe) or b the concentrations of total dissolved manganese (dMn). The data were determined at 22 in situ stations sampled across the Drake Passage and around the Western Antarctic Peninsula, including BIO1 as station West and BIO3 as station East (based on data of Tables 1, 3, 4). The two experimental stations West and East are indicated by dark circles while the PS97 stations are denoted by white circles and the PS112 stations by white triangles.
