| Abstract: | Background, aim, and scope Dissolved organic matter, measured as dissolved organic carbon (DOC), is an important component of aquatic ecosystems and
of the global carbon cycle. It is known that changes in DOC quality and quantity are likely to have ecological repercussions.
This review has four goals: (1) to discuss potential mechanisms responsible for recent changes in aquatic DOC concentrations;
(2) to provide a comprehensive overview of the interactions between DOC, nutrients, and trace metals in mainly boreal environments;
(3) to explore the impact of climate change on DOC and the subsequent effects on nutrients and trace metals; and (4) to explore
the potential impact of DOC cycling on climate change. |
