Seasonal and Annual Fluxes of Nutrients and Organic Matter from Large Rivers to the Arctic Ocean and Surrounding Seas
Robert M. Holmes,James W. McClelland,Bruce J. Peterson,Suzanne E. Tank,Ekaterina Bulygina,Timothy I. Eglinton,Viacheslav Gordeev,Tatiana Yu. Gurtovaya,Peter A. Raymond,Daniel J. Repeta,Robin Staples,Robert G. Striegl,Alexander V. Zhulidov,Sergey A. Zimov +13 more
TL;DR: In this article, seasonal and annual constituent fluxes have been determined using consistent sampling and analytical methods at the pan-Arctic scale and consequently provide the best available estimates for constituent flux from land to the Arctic Ocean and surrounding seas.
Journal ArticleDOI
Controls on the composition and lability of dissolved organic matter in Siberia's Kolyma River basin
Paul J. Mann,Anna Davydova,Nikita Zimov,Robert G. M. Spencer,Sergey Davydov,Ekaterina Bulygina,Sergei Zimov,Robert M. Holmes +7 more
TL;DR: In this paper, the authors examined DOC concentration and the composition of dissolved organic matter (DOM) across the hydrograph in Siberia's Kolyma River, with a particular focus on the spring freshet period when the majority of the annual DOC load is exported.
Journal ArticleDOI
High biolability of ancient permafrost carbon upon thaw
Jorien E. Vonk,Jorien E. Vonk,Jorien E. Vonk,Paul J. Mann,Sergey Davydov,Anna Davydova,Robert G. M. Spencer,John D. Schade,William V. Sobczak,Nikita Zimov,Sergei Zimov,Ekaterina Bulygina,Timothy I. Eglinton,Robert M. Holmes +13 more
TL;DR: In this paper, the authors showed that ancient dissolved organic carbon (DOC, >21,000 (14)C) was mobilized in stream waters draining Yedoma outcrops, and this DOC is highly biolabile: 34 +/- 0.8% was lost during a 14 day incubation under dark, oxygenated conditions at ambient river temperatures.
Journal ArticleDOI
Molecular Mapping of Sorbent Selectivities with Respect to Isolation of Arctic Dissolved Organic Matter as Measured by Fourier Transform Mass Spectrometry
Irina V. Perminova,Ivan V. Dubinenkov,Alexey S. Kononikhin,Andrey I. Konstantinov,Alexander Zherebker,Mantsa A. Andzhushev,Vasiliy A. Lebedev,Ekaterina Bulygina,Robert M. Holmes,Yury Kostyukevich,Igor Popov,Eugene N. Nikolaev +11 more
TL;DR: Structural imprints induced by a choice of the sorption technique were elucidated and high contribution of alkyl-chain protons into the spectral density of the arctic DOM reaching 43% for PPL isolates.
Journal ArticleDOI
Evidence for key enzymatic controls on metabolism of Arctic river organic matter.
Paul J. Mann,William V. Sobczak,Madeleine M. LaRue,Ekaterina Bulygina,Anna Davydova,Jorien E. Vonk,Jorien E. Vonk,John D. Schade,S. P. Davydov,Nikita Zimov,Robert M. Holmes,Robert G. M. Spencer +11 more
TL;DR: It is proposed that both composition and nutrient availability regulate DOM metabolism in Arctic aquatic ecosystems, informing reports of high biological availability of ancient, permafrost-derived DOM with clear ramifications for its metabolism in fluvial networks and feedbacks to climate.
