Marshy pools on permafrost mitigate landscape‐scale climate warming [PDF]

Eos, Transactions American Geophysical Union, 2014
Starting 5000 years ago, small marshy lakes dotting northern Siberia became significant carbon sinks, cooling the climate on a landscape scale. Researchers from the University of Alaska Fairbanks (UAF) published their findings in Nature online on 16 July.

Landscape Effects of Wildfire on Permafrost Distribution in Interior Alaska Derived from Remote Sensing

Remote Sensing, 2016
Climate change coupled with an intensifying wildfire regime is becoming an important driver of permafrost loss and ecosystem change in the northern boreal forest.

Summer CO2 evasion from streams and rivers in the Kolyma River basin, north-east Siberia [PDF]

, 2013
Inland water systems are generally supersaturated in carbon dioxide (CO2) and are increasingly recognized as playing an important role in the global carbon cycle.

Climate-driven thaw of permafrost preserved glacial landscapes, northwestern Canada [PDF]

Geology, 2017
Abstract Ice-marginal glaciated landscapes demarcate former boundaries of the continental ice sheets. Throughout circumpolar regions, permafrost has preserved relict ground ice and glacigenic sediments, delaying the sequence of postglacial landscape change that transformed temperate environments millennia earlier.

The Age and Origin of Block Deposits in the Victorian Alps, Australia

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

High resolution spatial variability in spring snowmelt for an Arctic shrub-tundra watershed [PDF]

, 2019
Arctic tundra environments are characterized by spatially heterogeneous end-of-winter snow cover because of high winds that erode, transport and deposit snow over the winter.

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

Icings and groundwater conditions in permafrost catchments of northwestern Canada

Scientific Reports, 2020
Icings are sheet-like masses of ice that form on the ground surface or in fluvial channels from groundwater seepage. Although the presence of icings in the landscape is known, few studies investigated their regional distribution and explored relations ...

Modeling the spatiotemporal variability in subsurface thermal regimes across a low-relief polygonal tundra landscape [PDF]

The Cryosphere, 2016
Vast carbon stocks stored in permafrost soils of Arctic tundra are under risk of release to the atmosphere under warming climate scenarios. Ice-wedge polygons in the low-gradient polygonal tundra create a complex mosaic of microtopographic features ...

Regulatory Framework and Public Policies for Sustainability in the Construction Sector

Sustainable Development, EarlyView.
ABSTRACT This study analyzes the role of public policies in promoting socially responsible practices in the construction sector, with a particular focus on their contribution to climate neutrality and the decarbonization of the building stock. European agreements exert increasing pressure to transform the construction sector, reinforcing the transition
