Objectif(s): To improve the understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and, to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean.
Description du projet: The objectives of this research are to: 1) Improve our understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels/ and 2) Decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. Specific activities for the coming field season include the following: This work will help resolve what drives microbial communities in Mackenzie Delta lakes to release the carbon in these waters to the atmosphere or to convert the carbon to a form consumed by fish and other organisms. Field work over the 5 years will be based on four areas within the delta, plus delta channels by the water gauging stations of Water Survey Canada, where the research team have worked extensively in the past. Objective (a): Assess open-water abundances of methane-producing and methane-consuming bacteria among Delta lak... Plus de résultats
