Numerous posters, oral, and organized sessions submitted to AGU continue to highlight science and science leadership by members of the NGEE Arctic project.
NGEE Arctic Returns to San Francisco for its Ninth All-Hands Meeting
Scientists from across the country gather for their ninth annual NGEE Arctic All-Hands meeting to celebrate success and discuss progress and plans for the project.
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
Impacts of microtopography on hydrologic and thermal states in an Arctic ecosystem: A case study using ELM-3D v1.0
Using a new three-dimensional hydrological and thermal capability in ELM (ELM-3D), scientists at LBNL analyzed the role of snow redistribution and lateral interconnectivity on soil temperatures and active layer.
