Controls on ecosystem respiration of carbon dioxide across a boreal wetland gradient in Interior Alaska [PDF]

, 2012
Thesis (M.S.) University of Alaska Fairbanks, 2012Permafrost and organic soil layers are common to most wetlands in interior Alaska, where wetlands have functioned as important long-term soil carbon sinks.

Arctic Geoengineering Between Governance and Science: A Structured Literature Review of the Arctic Geoengineering Discourse

WIREs Energy and Environment, Volume 14, Issue 2, June 2025.
Geoengineering research is largely concentrated on technical aspects, paying less attention to crucial legal/political issues and impacts on indigenous communities, highlighting a critical research gap as climate urgency intensifies, especially in the Arctic region.

Study of hydrothermal processes in ice-layers subgrade under constant temperature and dynamic loading

Scientific Reports
The presence of ice-layers in the subgrade soils makes the hydrothermal state of road subgrade built in island permafrost regions more susceptible to external environmental influences.

Global-scale estimation of diffuse groundwater recharge : model tuning to local data for semi-arid and arid regions and assessment of climate change impact [PDF]

, 2005
Groundwater recharge is the major limiting factor for the sustainable use of groundwater. To support water management in a globalized world, it is necessary to estimate, in a spatially resolved way, global-scale groundwater recharge.

Land Use Change and Infectious Disease Emergence

Reviews of Geophysics, Volume 63, Issue 2, June 2025.
Abstract Major infectious diseases threatening human health are transmitted to people from animals or by arthropod vectors such as insects. In recent decades, disease outbreaks have become more common, especially in tropical regions, including new and emerging infections that were previously undetected or unknown. Even though there is growing awareness

Segment Anything Model Can Not Segment Anything: Assessing AI Foundation Model's Generalizability in Permafrost Mapping [PDF]

arXiv
This paper assesses trending AI foundation models, especially emerging computer vision foundation models and their performance in natural landscape feature segmentation. While the term foundation model has quickly garnered interest from the geospatial domain, its definition remains vague.

Record Russian river discharge in 2007 and the limits of analysis [PDF]

, 2009
The Arctic water cycle has experienced an unprecedented degree of change which may have planetary-scale impacts. The year 2007 in particular not only was unique in terms of minimum sea ice extent in the Arctic Ocean but also was a record breaking year ...
