Reduced atmospheric acid deposition has given rise to recovery from acidification–defined
as increasing pH, acid neutralization capacity (ANC), or alkalinity in surface waters. Strong …

Freshwaters of the boreal and temperate regions have experienced increased browning
during the last decades. Browning, or brownification, is mostly driven by increased organic …

Terrestrial production and export of dissolved organic and inorganic carbon (DOC and DIC)
to streams depends on water flow and biogeochemical processes in and beneath soils. Yet …

Mountain headwater streams actively cycle carbon, receiving it from terrestrial landscapes
and exporting it through downstream transport and gas exchange with the atmosphere …

Small lakes are potentially effective environmental sensors; they react quickly to
anthropogenic stressors. We studied the long-term response of water chemistry to reduced …

Cumulative effects of nitrogen (N) deposition are a matter of concern in temperate forests of
northeastern North America. Increased N deposition may stimulate forest growth and carbon …

During major flood events, waterborne contaminants are relatively poorly characterized. This
is due to logistical difficulties associated with obtaining water samples in potentially …

This paper reviews currently available evaluations of the effects of continuously increasing
anthropogenic loads on water resources. The increase in the fluxes of elements and …

The paper presents results of a long-term (1990–2018) study of changes in the
geochemistry of land waters in the Kola region as a consequence of climate warming and a …

Intensification of brown color in surface waters has been observed over several decades in
many areas. We examined a 64‐yr daily record (1947–2010) of visual water color, a …
