Figure 2. Ratios of organic carbon vs. organic nitrogen and organic carbon vs. organic phosphorus of the sediment samples.

Figure 2

(A) Ratios of organic carbon vs. organic nitrogen and organic carbon vs. organic phosphorus along the continuum beginning from the Baltic Proper and western Gulf of Finland towards the eastern Gulf of Finland (sampling sites 1−9), (B) in the Ahvenkoskenlahti Bay estuary (sampling sites 10−12) and along the sediment depth. Refer to locations of the sediment sampling sites in Figures 1A and 1B.
