Progress and Accomplishments
Snapshot of simulated snowpack surface (cyan line) and ground temperature in a low centered polygon on December 24, 2014, demonstrating that rims function as preferential outlets of subsurface heat in winter, becoming the coldest zone of the polygon.
Investigations of topographic control on thermokarst development and the ground thermal regime in ice wedge polygons using the Advanced Terrestrial Simulator
NGEE Arctic researchers found that rim height and trough depth in ice wedge polygons considerably influence the vulnerability of the underlying permafrost, shaping feedbacks which ultimately control topographic deformation and increased soil aeration in t

Characterization of permafrost landscapes using an unmanned aerial system: LiDAR mapping the NGEE Arctic Teller field site
A state-of-the-art unmanned aerial system was deployed to collect centimeter-resolution imagery and topographic data of the NGEE Teller research site.
