Objectif(s): To examine the relationship between carbon accumulation and carbon gas fluxes in discontinuosly frozen peatlands in the Fort Simpson area. The estimation of past carbon accumulation rates will help to examine the long-term significance of peatlands in the carbon balance during the past 10,000 years. Current rates of carbon accumulation and release will help estimate the peatland contribution of carbon to the global carbon balance and the atmospheric greenhouse gas concentration.
Description du projet: Research will be conducted in a fen-bog complex approximately 5 km west of Fort Simpson. Gas samples will be obtained using portable chambers and later analyzed using gas chromotography. Cores will be collected using a peat corer and a modified ice auger. Peat temperatures, water levels, plant growth rates and water chemistry will also be measured. Geophysical mapping using ground penetrating radar will be used to map peat and permafrost characteristics.
