Long Term Vegetation Change Following Tundra Fire
Wildland fire is one of the most influential environmental processes across the Alaskan landscape. Fire affects all of the National Parks in the Arctic Network; in the past 50... -
Fate of Carbon in Soil Systems: Alaskan Landscapes
Formulates and tests scientific hypotheses to understand what key factors determine the fate of carbon in boreal terrestrial environments by examining the interaction of climate... -
Geophysical Investigations of Infrastructure Sites within the National Petroleum Reserve - Alaska (NPRA)
Study the geophysical response of infrastructure sites within the National Petroleum Reserve - Alaska (NPRA) that are threatened by erosion. The primary goal is to improve... -
USGS Gas Hydrates Project
Study gas hydrates by a variety of methods, but the ANS task is focused on determining what is the ultimate resource potential of the known gas hydrate and associated free-gas... -
Understanding the impacts of thermokarst lakes on permafrost stability, C cycling and greenhouse gas emissions
This research integrates field studies in a range of disciplines (geomorphology, geophysics, paleoecology, hydrology, limnology) with process modeling of permafrost thaw, lake... -
Climate Change, Permafrost, and Impacts on Civil Infrastructure
Permafrost, or perenially frozen ground, is a critical component of the cryosphere and the Arctic system. Permafrost regions occupy approximately 24% of the terrestrial surface... -
Carbon Chemistry and Microbiology of Permafrost Soils
Characterizes the carbon chemistry, microbial communities, and their function in surface and permafrost soils from throughout interior Alaska. This project is in close... -
Near Surface Permafrost Dynamics as an Essential Climate Variable
Permafrost was recently listed as a terrestrial Essential Climate Variable and several potential mechanisms of change can be quantified with remote sensing time series. We plan... -
Arctic Change
The objective of this website is to present recent indicators that describe the present state of the Arctic climate and ecosystem in an accessible, understandable, and credible... -
Ecology, Soil Carbon, and Permafrost Experiments (ECOSCAPE)
This experiment is structured to understand fundamental biogeochemical feedbacks from permafrost thaw, and address the needs of the Integrated Ecosystem Model (IEM) project... -
The roles of plant roots, mycorrhizal fungi and uptake of deep nitrogen in the permafrost carbon feedback to warming climate
Release of carbon frozen in permafrost (frozen ground) has been identified as one of the strongest and most likely positive feedbacks between the biosphere and the warming... -
Mapping Permafrost and Gas Hydrate using Marine Controlled Source Electromagnetic Methods (CSEM)
The objective of this project is to develop and test a towed electromagnetic source and receiver system suitable for deployment from small coastal vessels to map near-surface... -
Gas Hydrate Energy Production Studies in Northern Alaska
The primary objective of this effort is to evaluate the production response of the know gas hydrate accumulations in the area of the Prudhoe Bay and Kuparuk River production... -
Permafrost and Climate-Monitoring Network (DOI/GTN)
DOI/Global Terrestrial Network for Permafrost borehole array is used to monitor the thermal state of the underlying permafrost. This is the largest array of deep boreholes in...
