  • Thawing permafrost and methane emission in Siberia

  • Two decades of active layer thickness monitoring in northeastern Asia

    Andrey Abramov, Sergey Davydov et al.ARTICLEPolar Geography2019

    This study summarizes seasonal thawing data collected in different permafrost regions of northeast Asia over the 1995–2018 period. Empirical observations were undertaken under the Circumpolar Active Layer Monitoring (CALM) program at a range of sites across the permafrost landscapes of the Yana-Indigirka and Kolyma lowlands and the Chukotka Peninsula, and supplemented with 10 years of observations from volcanic mountainous areas of the Kamchatka …

  • Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire

    Open AccessBenjamin W Abbott, Jeremy B Jones et al.ARTICLEEnvironmental Research Letters2016

    As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of t…

  • Soil organic carbon pools in the northern circumpolar permafrost region

    Open AccessC Tarnocai, Josep G Canadell et al.ARTICLEGlobal Biogeochemical Cycles2009

    The Northern Circumpolar Soil Carbon Database was developed in order to determine carbon pools in soils of the northern circumpolar permafrost region. The area of all soils in the northern permafrost region is approximately 18,782 × 10 3 km 2 , or approximately 16% of the global soil area. In the northern permafrost region, organic soils (peatlands) and cryoturbated permafrost‐affected mineral soils have the highest mean soil organic carbon conte…

  • Building Resilience and Adaptation to Manage Arctic Change

    F Stuart Chapin, Michael Hoel et al.ARTICLEAMBIO2006Cited by: 9References: 10

    Unprecedented global changes caused by human actions challenge society's ability to sustain the desirable features of our planet. This requires proactive management of change to foster both resilience (sustaining those attributes that are important to society in the face of change) and adaptation (developing new socioecological configurations that function effectively under new conditions). The Arctic may be one of the last remaining opportunitie…

  • Rise and Fall of the Beringian Steppe Bison

    Open AccessBeth Shapiro, Alexei J Drummond et al.ARTICLEScience2004

    The widespread extinctions of large mammals at the end of the Pleistocene epoch have often been attributed to the depredations of humans; here we present genetic evidence that questions this assumption. We used ancient DNA and Bayesian techniques to reconstruct a detailed genetic history of bison throughout the late Pleistocene and Holocene epochs. Our analyses depict a large diverse population living throughout Beringia until around 37,000 years…

  • Spatial and Temporal Observations of Seasonal Thaw in the Northern Kolyma Lowland

    D G Fyodorov-Davydov, В А Сороковиков et al.ARTICLEPolar Geography2004

    Observations carried out in 1996-2002 in the northern part of the Kolyma Lowland reveal spatial and temporal regularities in the seasonal thawing of tundra and northern taiga soils. The main factor determining differences in active-layer thickness in zonal tundra landscapes is the texture (mechanical composition) of soil parent material. Summer thaw in sandy soils is 2-3 times deeper than in loamy soils. The distribution of maximum seasonal thaw …

  • Global Change and the Boreal Forest

    F Stuart Chapin, Terry V Callaghan et al.ARTICLEAMBIO2004Cited by: 8

    Changes in boreal climate of the magnitude projected for the 21st century have always caused vegetation changes large enough to be societally important. However, the rates and patterns of vegetation change are difficult to predict. We review evidence suggesting that these vegetation changes may be gradual at the northern forest limit or where seed dispersal limits species distribution. However, forest composition may be quite resilient to climate…

  • Wintertime CO2 Emission from Soils of Northeastern Siberia

    Open AccessS A Zimov, I P Semiletov et al.ARTICLEARCTIC1993

    The emission of C02 from northeastern Siberian soil was estimated for the period December 1989 to February 1990. Concentrations of air CO2 near the ground and 1 m above the snow cover were measured by an infrared gas analyzer. Fluxes of CO2 across the snow cover were calculated from the differences of these two values and the predetermined CO2 transfer coefficients at various flux rates through a layer of snow. Temperature and moisture content of…
