Determine whether rising dissolved organic carbon concentrations in northern surface waters stem primarily from climate change or from reductions in atmospheric acid deposition.
Conducted controlled peat-core experiments to quantify dissolved organic carbon production under aerobic and anaerobic conditions across varying temperatures.
Performed statistical time-series analyses of chemical trends and deposition records across 11 UK Acid Waters Monitoring Network lakes monitored since 1988.
Dissolved organic carbon concentrations in monitored UK waters increased by an average of 91% since 1988.
Statistical analysis demonstrated an inverse relationship between soil solution sulfate and dissolved organic carbon, with declining sulfur deposition, changing sea-salt inputs, and temperature accounting for most of the trend.

No takes yet. Share an insight, caveat, or question.

Implication

Longitudinal monitoring and experimental study reveals declining sulfur deposition drives rising dissolved organic carbon in surface waters, indicating ecosystem recovery rather than destabilization.
