Study Site: Abitibi and Saguenay, Quebec
Purpose: Methane (CH4) emissions from aquatic systems should be coupled to CH4 production, and thus a temperature-dependent process, yet recent evidence suggests that modeling CH4 emissions may be more complex due to the biotic and abiotic processes influencing emissions. We studied the magnitude and regulation of two CH4 pathways—ebullition and diffusion.
Abstract: Beaver ponds were sampled between 2010 and 2011 in two different regions of Québec: Abitibi (48.07 – 48.94°N, 79.47 – 78.65°W) and Saguenay (47.79 – 48.77°N, 72.13 – 70.65°W). The data collected in the Saguenay region have been presented in DelSontro and others (2016), whereas the data collected in Abitibi have not been published, but the sampling methodology is common to both sets. In brief, sites were selected to cover the broadest diversity of ponds, with wide gradients of shape, size, type of flooded soils, and trophic status. Most of the sampled ponds had shallow depths between 1 and 3 m. In Abitibi, 41 beaver ponds were sampled during the ice-free season. A selection of these ponds was sampled at least four times, from May to November. In Saguenay, 10 ponds were sampled three times (June, July, and September).
