Fig. 3

Distributions of Fv/Fm* below 0.35 (< mean—SD), within 0.35–0.41 (within mean ± SD) and above 0.41 (> mean + SD) at three different transects, (a) Transect 2, (b) Transect 4 and, (c) Transect 5. Chlorophyll a concentrations are shown as contours (Chlorophyll a, µg L−1). The figure was made using the scientific graphic language Gri (version 2.12.23, https://gri.sourceforge.net/).
