Thermokarst-lake methanogenesis along a complete talik profile
J.K. Heslop,K. M. Walter Anthony,Armando Sepulveda-Jauregui,Karla Martinez-Cruz,Karla Martinez-Cruz,Allen C. Bondurant,Guido Grosse,Guido Grosse,Miriam C. Jones +8 more
TL;DR: In this paper, the authors assessed anaerobic CH4 production potentials from various depths along a 590 cm long lake sediment core that captured the entire sediment package of the talik (thaw bulb) beneath the center of an interior Alaska thermokarst lake, Vault Lake, and the top 40 cm of thawing permafrost beneath a talik.

Increasing Organic Carbon Biolability With Depth in Yedoma Permafrost: Ramifications for Future Climate Change
Journal ArticleDOI
First evidence for cold-adapted anaerobic oxidation of methane in deep sediments of thermokarst lakes
Matthias Winkel,Armando Sepulveda-Jauregui,Karla Martinez-Cruz,J.K. Heslop,Ruud Rijkers,Fabian Horn,Susanne Liebner,K. M. Walter Anthony +7 more
TL;DR: In this article, the pore water of a thermokarst lake sediment core was analyzed to detect anaerobic oxidation of methane (AOM) in thermokara-st lakes, showing that 41 to 83% of dissolved CH 4 is consumed anaerobically.
Journal ArticleDOI
A synthesis of methane dynamics in thermokarst lake environments
J.K. Heslop,K. M. Walter Anthony,Matthias Winkel,Armando Sepulveda-Jauregui,Karla Martinez-Cruz,Allen C. Bondurant,Guido Grosse,Guido Grosse,Susanne Liebner +8 more
TL;DR: In this paper, the authors synthesize several studies examining CH4 dynamics in a representative first-generation thermokarst lake (Vault Lake, informal name) to show that CH4 production and oxidation potentials vary with depth in thawed sediments beneath the lake.
Journal ArticleDOI
Emerging dominance of summer rainfall driving High Arctic terrestrial-aquatic connectivity
C. R. Beel,J.K. Heslop,John F. Orwin,John F. Orwin,M. A. Pope,A. J. Schevers,J. K. Y. Hung,Melissa J. Lafrenière,Scott F. Lamoureux +8 more
TL;DR: In this paper, the authors integrated decade-long hydrometeorological and biogeochemical data from the High Arctic to show that shifts in the timing and magnitude of annual discharge patterns and stream power budgets are causing Arctic material transfer regimes to undergo fundamental changes.
