Holocene climate changes in eastern Beringia (NW North America)–A systematic review of multi-proxy evidence
Reconstructing climates of the past relies on a variety of evidence from a large number of
sites to capture the varied features of climate and the spatial heterogeneity of climate …

Permafrost thaw in northern peatlands: rapid changes in ecosystem and landscape functions
Peatlands within the northern permafrost region cover approximately 2 million km2 and are
characterized by organic soils that can be several meters thick, and a fine-scale mosaic of …

Camera network calibration from dynamic silhouettes
SN Sinha, M Pollefeys… - Proceedings of the 2004 …, 2004 - ieeexplore.ieee.org
In this paper we present an automatic method for calibrating a network of cameras from only
silhouettes. This is particularly useful for shape-from-silhouette or visual-hull systems, as no …

Effect of permafrost thaw on CO2 and CH4 exchange in a western Alaska peatland chronosequence
CE Johnston, SA Ewing, JW Harden… - Environmental …, 2014 - iopscience.iop.org
Permafrost soils store over half of global soil carbon (C), and northern frozen peatlands store
about 10% of global permafrost C. With thaw, inundation of high latitude lowland peatlands …

Inconsistent response of Arctic permafrost peatland carbon accumulation to warm climate phases
H Zhang, AV Gallego‐Sala… - Global …, 2018 - Wiley Online Library
Northern peatlands have accumulated large carbon (C) stocks since the last deglaciation
and during past millennia they have acted as important atmospheric C sinks. However, it is …

Near-surface permafrost aggradation in Northern Hemisphere peatlands shows regional and global trends during the past 6000 years
The history of permafrost aggradation and thaw in northern peatlands can serve as an
indicator of regional climatic history in regions where records are sparse. We infer regional …

Holocene vegetation dynamics of circum-Arctic permafrost peatlands
Vegetation shifts in circum-Arctic permafrost peatlands drive feedbacks with important
consequences for peatland carbon budgets and the extent of permafrost thaw under …

Geomorphological and cryostratigraphical analyses of the Zackenberg Valley, NE Greenland and significance of Holocene alluvial fans
S Cable, HH Christiansen, A Westergaard-Nielsen… - Geomorphology, 2018 - Elsevier
Abstract In High Arctic northern Greenland, future responses to climatic changes are poorly
understood on a landscape scale. Here, we present a study of the geomorphology and …
