Journal ArticleDOI

Gustaf Hugelius,Jens Strauss,Sebastian Zubrzycki,Jennifer W. Harden,Edward A. G. Schuur,Edward A. G. Schuur,Chien-Lu Ping,Lutz Schirrmeister,Guido Grosse,Gary J. Michaelson,Charles D. Koven,Jonathan A. O'Donnell,Bo Elberling,Umakant Mishra,Philip Camill,Zicheng Yu,Juri Palmtag,Peter Kuhry +17 more
TL;DR: In this article, the authors presented revised estimates of permafrost organic carbon stocks, including quantitative uncertainty estimates, in the 0-3 m depth range in soils as well as for sediments deeper than 3 m in deltaic deposits of major rivers and in the Yedoma region of Siberia and Alaska.
Journal ArticleDOI
Field information links permafrost carbon to physical vulnerabilities of thawing
Jennifer W. Harden,Charles D. Koven,Chien-Lu Ping,Gustaf Hugelius,A. David McGuire,P. Camill,T. Jorgenson,Peter Kuhry,Gary J. Michaelson,Jonathan A. O'Donnell,Edward A. G. Schuur,Charles Tarnocai,Kristopher Johnson,Guido Grosse +13 more
TL;DR: In this article, deep soil profiles containing permafrost (Gelisols) were characterized for organic carbon (C) and total nitrogen (N) stocks to 3 m depths using the Community Climate System Model (CCSM4).
Journal ArticleDOI

TL;DR: In this paper, a meta-analysis of soil incubation studies from the permafrost zone suggests that thawing under aerobic conditions, which releases CO2, will strengthen the carbon feedback more than waterlogged systems, which release CO2 and CH4.
Journal ArticleDOI
Expert assessment of vulnerability of permafrost carbon to climate change

TL;DR: In this article, the authors used a survey to quantify variability in the perception of the vulnerability of permafrost C to climate change and found that approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafure zone, more than twice as much C than in the atmosphere.
Journal ArticleDOI
Reorganization of vegetation, hydrology and soil carbon after permafrost degradation across heterogeneous boreal landscapes
M. Torre Jorgenson,Jennifer W. Harden,Mikhail Kanevskiy,Jonathan A. O'Donnell,Kim Wickland,Stephanie A. Ewing,Kristen L. Manies,Qianlai Zhuang,Yuri Shur,Robert G. Striegl,Joshua C. Koch +10 more
TL;DR: In this paper, the authors used a chronosequence approach to assess changes in vegetation composition, water storage and soil organic carbon (SOC) stocks along successional gradients within four landscapes: (1) rocky uplands on ice-poor hillside colluvium, (2) silty uplands with extremely ice-rich loess, (3) gravelly-sandy lowlands on eolian sand and (4) peaty-silty lowlands with thick peat deposits over reworked lowland loess.
