Inland waters receive and process significant but poorly-constrained amounts of terrestrial carbon. A portion of terrestrially-derived carbon in inland waters is microbially processed into the greenhouse gasses carbon dioxide and methane then outgassed into the atmospheric carbon pool, making inland waters important components of the global carbon cycle. My research at Cape Bounty Arctic Watershed Observatory aims to quantify and characterize terrestrially-derived carbon export, microbial processing potentials, and greenhouse gas flux potentials from ponds with a range of hydrological inputs (precipitation-fed versus soil water-influenced), vegetation types (mesic tundra, polar desert), and permafrost disturbance regimes (thermokarst, active layer detachment, undisturbed). This research will improve understanding of how these hydrological and landscape characteristics affect greenhouse gas production in the Canadian High Arctic, with implications towards better understanding circumpolar permafrost carbon cycling.
