Permafrost carbon fluxes
Principal Investigator: Pumpanen, Jukka S
Licenced Year(s): 2019
Summary: The field work in Trail Valley Creek and Inuvik aims to study: 1) how catchment characteristics, such as vegetation and soil properties, control the amount and quality of aquatic dissolved organic matter (DOM) and its microbial degradability, and 2) how these factors further regulate greenhouse gas fluxes (carbon dioxide CO2, methane CH4, nitrous oxide N2O) from Arctic lakes. At the Dempster hi...


ARCTICFIRE
Principal Investigator: Pumpanen, Jukka S
Licenced Year(s): 2018 2015
Summary: The aim of the ARCTICFIRE project is to study the long term effects of natural forest fires on the decomposition of soil organic matter in the northern arctic and subarctic forests. The research team will study the changes in size and quality of soil carbon and nitrogen pools and fluxes after forest fires and their underlying processes in the arctic and subarctic zone, especially the interactions ...
