Promoting respect and working with Arctic Indigenous communities
Since its inception, the NGEE Arctic project has worked hard to develop and promote a culture of safety, respect, and inclusion.

Ground Subsidence in Arctic Tundra Unlikely to Trigger Abrupt Thaw
Drying of tundra landscapes will limit subsidence-induced acceleration of permafrost thaw.
Remote Sensing from Unoccupied Aerial Systems: Opportunities to Enhance Arctic Plant Ecology in a Changing Climate
The Arctic is warming at a faster rate than any other biome on Earth, resulting in widespread changes in vegetation composition, structure, and function that have important feedbacks to the global climate system.
Progress and Accomplishments
NGEE Arctic team outlines anticipated approach for Phase 4 (2025–2027) of the project
The anticipated approach for NGEE Arctic Phase 4 leverages computational, diagnostic, remote sensing, and data synthesis tools to quantify improvements in prediction of climate–ecosystem feedbacks at the global scale in an Arctic-informed version of the land surface component of the Department of Energy’s (DOE’s) Energy Exascale Earth System Model (E3SM). NGEE Arctic Phase 4 will deliver an unprecedented ability to predict the consequences of interacting Arctic processes for the global climate.
Patterns and rates of soil movement and shallow failures across several small watersheds on the Seward Peninsula, Alaska
The presence and thawing of permafrost strongly control both gradual and catastrophic movements of soil on watershed hillslopes in complex and often difficult to predict patterns and rates.
Inhibition of methane (CH4) and methylmercury (MeHg) formation by nitrous oxide (N2O) in Arctic tundra soil microcosms
Nitrous oxide strongly inhibits CH4 and MeHg formation, resulting from the complicated interplay of microbial processes in anoxic soils that ultimately determine how climate change will influence greenhouse gas formation and mercury transformation in the Arctic ecosystem.
