Ground Subsidence in Arctic Tundra is Unlikely to Trigger Abrupt Thaw
Drying of tundra landscapes will limit subsidence-induced acceleration of permafrost thaw.
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.
Progress and Accomplishments
The NGEE Arctic Team Defends the Phase 4 Proposal
The NGEE Arctic team presented and defended a proposal for Phase 4 science in front of a review panel comprising nearly a dozen international arctic empiricists and modelers.
Arctic Thermokarst Wetland Vegetation Alters Belowground Biogeochemistry and Soil Gas Flux
We are conducting a greenhouse experiment with live Arctic thermokarst wetland vegetation to pinpoint important biogeochemical processes in these changing ecosystems.
Deep Permafrost Thaw: A Significant and Overlooked Source of Greenhouse Gas
Energy conducted by water can result in faster and deeper permafrost thaw.
