Estimating methane emissions from northern lakes using ice‐bubble surveys
Katey M. Walter Anthony,D. A. Vas,Laura Brosius,F. Stuart Chapin,Sergey A. Zimov,Qianlai Zhuang +5 more
TL;DR: In this article, the authors presented a field method to estimate an important and highly uncertain source: ebullition from northern lakes, and they defined four classes of CH4 bubble clusters trapped in lake ice representing distinct types of biogenic Ebullition seeps that differed in flux rate.
Using the deuterium isotope composition of permafrost meltwater to constrain thermokarst lake contributions to atmospheric CH4 during the last deglaciation
Laura Brosius,K. M. Walter Anthony,Guido Grosse,J. Chanton,Louise M. Farquharson,Pier Paul Overduin,Hanno Meyer +6 more
TL;DR: In this paper, the authors demonstrate that meltwater from permafrost ice serves as an H source to CH4 production in thermokarst lakes, allowing for region-specific reconstructions of ΔDCH4 emissions from Siberian and North American lakes.

Decadal-scale hotspot methane ebullition within lakes following abrupt permafrost thaw
K. M. Walter Anthony,Prajna R Lindgren,P. Hanke,M. J. Engram,Peter Anthony,Ronald P. Daanen,Allen C. Bondurant,Anna K. Liljedahl,Josefine Lenz,Guido Grosse,Guido Grosse,Benjamin M. Jones,Laura Brosius,S. R. James,Burke J. Minsley,Neal J. Pastick,J. Munk,Jeffrey P. Chanton,Charles E. Miller,Franz J. Meyer +19 more
TL;DR: In this article, the authors combined field measurements and radiocarbon dating of CH4 ebullition with an assessment of lake area changes delineated from high-resolution (1.5 m) optical imagery and geophysical measurements of thaw bulbs (taliks) to determine the spatiotemporal dynamics of hotspot-seep CH4 emissions in interior Alaska thermokarst lakes.

Spatiotemporal patterns of northern lake formation since the Last Glacial Maximum
Laura Brosius,K. M. Walter Anthony,Claire C. Treat,Claire C. Treat,Claire C. Treat,Josefine Lenz,Josefine Lenz,Miriam C. Jones,M.S. Bret-Harte,Guido Grosse,Guido Grosse +10 more
TL;DR: In this paper, the synthesis of 1207 northern lake initiation records presented here provides an analog for rapid landscape-level change in response to climate warming, and its subsequent attenuation by physical and biological feedback mechanisms.

The role of wetland expansion and successional processes in methane emissions from northern wetlands during the Holocene
Claire C. Treat,Claire C. Treat,Claire C. Treat,Miriam C. Jones,Laura Brosius,Guido Grosse,Guido Grosse,Katey M. Walter Anthony,Steve Frolking +8 more
TL;DR: This paper reconstructed CH4 emissions from northern peatlands from 13,000 BP to present using an empirical model based on observations of peat initiation (>3600 dates), peatland type (>250 peat cores), and observed CH4 emission.
