All good things come in threes: Third paper on permafrost and thermokarst dynamics highlighted by JGR Biogeosciences

A third paper resulting from our group's work on permafrost and thermokarst dynamics, funded by NASA Carbon Cycle Sciences and the NSF Arctic Program, was now selected as Editors' Highlight in Journal of Geophysical Research - Biogeosciences and as Research Spotlight in EOS. The paper was led by graduate student Laura Brosius and reports linkage of regionally varying ground ice isotopes with thermokarst lake methane emissions to reconcile bottom-up estimates of thermokarst lake methane emissions in various Arctic regions with isotope constraints from ice core records. Findings add another indication that thermokarst lakes were indeed an important source of atmospheric methane during the deglacial period. Link to JGR website.
