Increased colour and organic acid concentrations in Norwegian forest lakes and drinking water – a result of increased precipitation?
Abstract.Recently there have been major increases in water colour and dissolved organic carbon (DOC) in many forest lakes that serve as drinking water reservoirs in the southern part of Norway. WeExpand

Dissolved components in precipitation water percolated through forest litter
Leaves lying on the forest floor are a major source of dissolved organic substances in soil and surface waters, and these substances have important effects in those environments. We used zero-tensiExpand

Quantifying the drivers of the increasing colored organic matter in boreal surface waters.
Long-term monitoring of surface water quality has shown increasing concentrations of colored dissolved organic matter (CDOM) across large parts of the northern latitudes. This has increasedExpand

Seasonal Mixing and Genesis of Endogenic Meromixis in Small Lakes in Southeast Norway
The inland region of Southeast Norway contains many lakes with endogenic meromixis. A synoptic study of seasonal mixing was conducted in 27 oligo- and mesotrophic lakes with surface area 0.0013 – 7.4Expand
