Retrospective Analysis of Permafrost Landscape Evolution in Yakutia during the Holocene Warm Intervals

Land, 2020
The observed global warming has significant impacts on permafrost. Permafrost changes modify landscapes and cause damage to infrastructure. The main purpose of this study was to estimate permafrost temperatures and active-layer thicknesses during the ...

PeRL: a circum-Arctic Permafrost Region Pond and Lake database [PDF]

Earth System Science Data, 2017
Ponds and lakes are abundant in Arctic permafrost lowlands. They play an important role in Arctic wetland ecosystems by regulating carbon, water, and energy fluxes and providing freshwater habitats. However, ponds, i.e., waterbodies with surface areas

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]

, 2017
The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Transformative Pathways for Strengthening Climate‐Resilient Health Systems Among Indigenous Communities: Advancing Equity and Sustainability in Global Health

Sustainable Development, EarlyView.
ABSTRACT Most climate‐resilience health interventions are designed at the global level, with minimal attention to Indigenous communities' needs. The lack of consideration can lead to unintended harm and exacerbate health risks. This study aims to identify the capacities of Indigenous communities that can serve as transformative pathways in safely ...

Divergent Spatiotemporal Patterns and Climate Responses of Lateral and Internal Lake Drainage in the Northern Permafrost Region

Geophysical Research Letters
Lake drainage is a key manifestation of permafrost degradation with implications for hydrology, landscape dynamics and carbon feedbacks. Lake drainage occurs through two distinct mechanisms, namely lateral drainage and internal drainage.

InSAR-derived seasonal subsidence reflects spatial soil moisture patterns in Arctic lowland permafrost regions [PDF]

The Cryosphere
The identification of spatial soil moisture patterns is of high importance for various applications in high-latitude permafrost regions but challenging with common remote sensing approaches due to high landscape heterogeneity.

Diversity and potential activity of methanotrophs in high methane-emitting permafrost thaw ponds. [PDF]

PLoS ONE, 2017
Lakes and ponds derived from thawing permafrost are strong emitters of carbon dioxide and methane to the atmosphere, but little is known about the methane oxidation processes in these waters.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

Archaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...
