The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and
human/cultural systems that may be irreversible on century time scales and have the …

Background and aims Wetland plants inhabit flood-prone areas and therefore can
experience episodes of complete submergence. Submergence impedes exchange of O2 …

The concentrations of terrestrially derived dissolved organic carbon have been increasing
throughout northern aquatic ecosystems in recent decades, but whether these shifts have an …

Colored dissolved organic matter (CDOM) absorbs a substantial fraction of
photosynthetically active radiation (PAR) in boreal lakes. However, few studies have …

Dissolved organic carbon (DOC) is a key parameter in lakes that can affect numerous
features, including microbial metabolism, light climate, acidity, and primary production. In an …

Annual CO2 emissions from lakes and other inland waters into the atmosphere are
estimated to almost entirely compensate the total annual carbon uptake by oceans,,. CO2 …

A growing body of evidence suggests that most of the world's lakes are supersaturated with
CO2 and export significant amounts of CO2 to the atmosphere. Still, the temperature …

We calculated the carbon loss (mineralization plus sedimentation) and net CO2 escape to
the atmosphere for 79 536 lakes and total running water in 21 major Scandinavian …

Organic carbon inputs from outside of ecosystem boundaries potentially subsidize recipient
food webs. Four whole‐lake additions of dissolved inorganic 13C were made to reveal the …

We show that sediment respiration is one of the key factors contributing to the high CO2
supersaturation in and evasion from Finnish lakes, and evidently also over large areas in the …
