Carbon and energy fluxes at the Mer Bleue bog
Peatlands are wetlands that have accumulated at least 30-40 cm of partially decomposed organic material. Carbon accumulates due to a small imbalance between plant production and decomposition. Although northern peatlands occupy only 3% of the land surface, the C stored within this peat makes up about one-third of the total global soil C pool.
We are making continuous measurements of CO2, energy and water fluxes at Mer Bleue, a low shrub ombrotrophic bog just outside Ottawa, Ontario. This long-term dataset is being used to shed light on the response of peatland C cycling to variations in weather and to help us understand how the C sink strength may change with climate warming. Measurements began in 1998 originally as part of the Peatland Carbon Study (PCARS). The measurements were continued as part of the Fluxnet Canada Research Network and the Canadian Carbon Project. Past data is available here.
