Monitoring pH of seawater in the Adriatic sea. Results from a regional observing effort

Ocean acidification in the Mediterranean Sea is expected to have a rapid response to the climate change, being its hydrological balance deficient and anthropogenic forcing high. So the basin can be regarded as a key site very sensitive to the climate variability, especially in dense cold water formation areas. In this frame, the Adriatic Sea can play a very relevant role for the entire Eastern Mediterranean Sea, since in winter is exposed to cold dry winds eventually producing dense waters (NAdDW, ADW), which are important contributors to the Eastern Mediterranean deep circulation. Here are presented results of two repeated surveys, on mesoscale, and those of two short timeseries, one representative of a coastal environment and the other of open sea. Preliminary results, based on spectrophotometric analysis of pH (total scale, precision of ± 0.001 pHT units), indicate the two times series reflect dynamics and processes of their respective environments.
