Long-term monitoring data reveal pH dynamics, trends and variability in the western Gulf of Finland

Many studies present models of future ocean pH, whereas relatively few papers present measured pH data (Santana-Casiano et al. 2007, Wootton et al. 2008, Olafsson et al. 2009, Omstedt et al. 2010, Provoost et al. 2010). The aim of the present study is to demonstrate pH dynamics and its variability, and whether pH shows a decreasing trend in the Gulf of Finland since the beginning of the 1970s until today. We present long-term pH data collected between 1972 and 2009 at Längden and Storgadden monitoring stations in the outer archipelago of Tvärminne in the western Gulf of Finland, Baltic Sea.
