Sažetak
Since the beginning of the Industrial era, oceanic uptake of CO2 has resulted in the acidification of the ocean ; the pH of ocean surface water has decreased by 0.1 and a further decrease of 0.4 units is expected for the end of the century. These changes have effects on the marine biota, especially on calcifying organisms, like planktonic calcifiers, corals, sea urchins, bivalve mollusks, and then have consequences on the entire trophic chain. The negative impact of ocean acidification could be enhanced in some coastal ecosystems, such as the semi – enclosed shallow northern Adriatic, characterized by the presence of numerous riverine inputs and high variability of its biogeochemical properties. It is also an area with marked anthropogenic pressure, being surrounded by highly industrial regions, in which an acidification process of 0.0025 pHT units/year was previously observed.
