Figure 1. Location of sampling sites, seawater trophic status and planktonic microbiological parameters in Rio de Janeiro.

Figure 1

(A) The location of Guanabara Bay in South America is indicated on the map (upper left corner). The map on the upper right corner shows the location of Guanabara Bay in reference to Rio de Janeiro state. The lower panel shows a detailed map of Guanabara Bay and the location of the two sampling sites: the pillar 92 of the Rio-Niterói Bridge, the inner bay site (P92) and the Cagarras Archipelago (CA), the outer bay site. (B) Ammonium, phosphate and chlorophyll a concentrations in seawater inside (black bars) and outside Guanabara Bay (gray bars). (C) Planktonic prokaryotic abundance and production inside (black bars) and outside the bay (gray bars).
