Abstract (in english)
   Variations in surface water S chemistry were investigated at a waterlogged raised peatland in the NE of England from 1994 to 2000. While S inputs were important, below-ground cycling of S, dependent upon water table height, played a dominant role in affecting SO4 concentration of the surface waters. Evaporative concentration of SO4 during drought played only a subordinate role in increasing SO4 concentrations. At Thorne Moors SO4 in surface water shows a clear and statistically significant trend: (i) high concentrations (relative to pristine bogs) (mean 18 mg L-1) under high pollutant loadings before drought; (ii) extremely elevated concentrations (mean 52 mg L-1) under declining pollutant loadings during drought in 1996 and lowered water tables; (iii) recovery to significantly lower concentrations (mean 4.3 mg L-1) as water tables recovered (due to increased rain and site management) whilst pollutant loadings continued to fall.
   The increase in surface water SO4 in 1996 was accompanied by a significant rise in the S content of Sphagnum moss growing on the surface of the pools. As such the S content of Sphagnum may act as a proxy for variations in surface water S chemistry and thus environmental change
