The contribution of fish and their relative importance in the nutrient dynamics of lakes (sink vs. source) continue to be a topic of debate (Mehner et al. 2007; Wurtsbaugh 2007; Sereda et al. 2008b). ...

Radon-222, a naturally-occurring radioisotope with a half-life of 3.8 days, was used to estimate groundwater discharge to small lakes in wetland-dominated basins in the vicinity of Fort McMurray, Cana...

We calculated average aquatic dissolved organic carbon (DOC) age (the time span from soil discharge to
observation) in water from the inlets and outlets of two unproductive Swedish lakes at different...
Long-term patterns in dissolved organic carbon in boreal lakes: the role of incident radiation, precipitation, air temperature, southern oscillation and acid deposition

Both lake-specific (e.g. pH) and regional (e.g. precipitation) factors affect DOC concentration and pattern. Using annual DOC concentration in nine boreal lakes in the ice-free season, the potential i...

A field study in a boreal lake using a remotely operated vehicle equipped with a camera established that falling
fish carcasses did not tend to be buried in sediments after deposition. Decomposition ...

The variability of surface water carbon dioxide concentration, or partial pressure (pCO2
), was studied in 11 lakes
of greatly varying size (2.4 ha up to 8 million ha) in Northwest Ontario, Canada. ...
