ABoVE: Methane Flux across Two Thermokarst Lake Ecosystems, Interior Alaska, 2018 : Arctic-Boreal Vulnerability Experiment (ABoVE)
This dataset provides diffusive methane (CH4) fluxes collected from two thermokarst lakes in the Goldstream Valley, north of Fairbanks in interior Alaska. Fluxes were collected from the littoral zones, adjacent shoreline, and upland vegetation. The data were collected during July 2018. Measurements...
