THE SURFACE-WATER ACIDIFICATION PROJECT (SWAP) PALEOLIMNOLOGY PROGRAM

Improvements in techniques of lake-sediment analysis over the last two decades have enabled palaeolimnologists to reconstruct changes in water acidity and atmospheric contamination with high resolution. In SWAP these techniques have been used to trace the history of a range of specially selected study sites and to evaluate alternative causes for lake acidification. At the same time further improvements in some of the techniques, especially diatom analysis, have been made. -from Authors
