Lafleur,Hanna Lee,Galina Mazhitova,Frederick E. Nelson,Annette Rinke,Vladimir E. Romanovsky,Nikolay I. Shiklomanov,Charles Tarnocai,Sergey Venevsky,Jason G. Vogel,Sergei Zimov +18 more
TL;DR: In this article, the authors present an overview of the global permafrost C pool and of the processes that might transfer this C into the atmosphere, as well as the associated ecosystem changes that occur with thawing.

TL;DR: O 3 at 1·5 × ambient completely offset the growth enhancement by CO 2 , both for O 3 -sensitive and O 2 -tolerant clones and across various trophic levels, and implications for carbon sequestration, plantations to reduce excess CO 2, and global models of forest productivity and climate change are presented.

Spatial Extent, Age, and Carbon Stocks in Drained Thaw Lake Basins on the Barrow Peninsula, Alaska
Kenneth M. Hinkel,Wendy R. Eisner,James G. Bockheim,Frederick E. Nelson,Kim M. Peterson,Xiaoyan Dai +5 more
TL;DR: In this article, the relative age of 77 basins on the Barrow Peninsula was estimated using the degree of plant community succession and verified by radiocarbon-dating material collected from the base of the organic layer in 21 basins.
Journal ArticleDOI
Estimating active-layer thickness over a large region: Kuparuk River Basin, Alaska, U.S.A
Frederick E. Nelson,Nikolay I. Shiklomanov,G. R. Mueller,Kenneth M. Hinkel,Donald A. Walker,James G. Bockheim +5 more
TL;DR: Active-layer thickness was mapped over a 26,278 km2 area of northern Alaska containing complex and highly variable patterns of topography, vegetation, and soil properties as discussed by the authors, and procedures included frequ...
