Abstract:
This dataset contains calculated fluxes of CH4 and CO2 from surface waters in September 2021 in Lake 3 near the Mackenzie Delta, Northwest Territories, Canada. We measured surface water gas concentrations from a small boat using a closed loop chamber and a Microportable Greenhouse Gas Analyzer (Los Gatos Research). The measurements were part of the "Mackenzie Delta Permafrost Field Campaign" (mCan2021) within the "Modular Observation solutions for Earth Systems" (MOSES) program.
