Short summary
Global warming thaws permafrost and accelerates the formation of thaw ponds in subarctic and arctic regions. These abundant ponds receive large terrestrial carbon inputs from the thawing and eroding permafrost, which is mainly used by bacterioplankton for the production of new biomass. Bacteria metabolism also produces high levels of CO2 and CH4, which make thaw ponds important sources of greenhouse gases to the atmosphere. We present carbon dynamics in thaw ponds in northern Quebec.
