Study Site: Lutose peatland, Interior Plains of western Canada
Purpose: Permafrost thaw in northern peatlands causes collapse of permafrost peat plateaus and thermokarst bog development, with potential impacts on atmospheric greenhouse gas exchange.
Abstract: The data provided in one xlsx file has two tabs: read me, and data. "Read me" contains descriptions of all column headers and data. It provides units of measurement for each. "Data" contains 1,071 net ecosystem exchange (NEE), 1,201 ecosystem respiration (ER), 1,007 gross primary production (GPP), and 960 methane (CH4) flux measurements collected from 2016-2018. It also contains where along two permafrost thaw transects the measurements were taken, the date they were taken, and environmental data (water table, soil temperature, photosynthetically active radiation) measured at the same time as each flux measurement. These flux measurements and corresponding environmental data were used to construct flux models and estimate annual greenhouse gfs balances.
