Methane Fluxes from Shorelines and Differing Surfaces, Big Trail Lake, Alaska, 2019 : Arctic-Boreal Vulnerability Experiment (ABoVE)
This dataset provides methane fluxes from hot-spot and non-hot spot differing surfaces at Big Trail Lake (BTL) in the Goldstream Valley near Fairbanks, AK, USA. Measurements were taken at a remotely-sensed methane hotspot on the shoreline of a pond, adjacent to BTL with a Los Gatos Ultra-Portable Gr...
