Effects of year-to-year variations in climate on trends in acidification (ICP Waters report 57/2001)

- NIVA-rapport 
Climatic variations potentially mask long-term trends in acidification of surface waters. High inputs of seasalts due to severe storms can cause temporary decreases in ANC. Temperature and moisture may affect nitrate leaching. Concentrations of dissolved organic carbon are also potentially related to climate. The North Atlantic Oscillation provides a general index of climatic conditions in northwestern Europe. Although variations in the NAO index can account for some of the observed trends in surface water chemistry at sites in the UK, it does not appear to be a good explanatory factor for sites in Norway. More research is necessary to discover which climatic factors best explain natural variations in surface waters.
