| Zusammenfassung |
| Recent observations and modelling studies suggest that biogeochemical changes
can mask atmospheric CO2-induced pH decreases. Data collected by the
Dutch monitoring authorities in different coastal systems (North Sea, Wadden
Sea, Ems-Dollard, Eastern Scheldt and Scheldt estuary) since 1975 provide an
excellent opportunity to test whether this is the case in the Dutch coastal
zone. The time-series were analysed using Multi-Resolution Analysis (MRA)
which resulted in the identification of system-dependent patterns on both
seasonal and intra-annual time scales. The observed rates of pH change
greatly exceed those expected from enhanced CO2 uptake, thus suggesting
that other biogeochemical processes, possibly related to changes in nutrient
loading, can play a dominant role in ocean acidification. |
