The Ecosystem Type workshop was held in October and included participation from 60 scientists, students, and researchers from the NGEE Arctic team.

Scientists at UAF developed a spatially distributed permafrost model for the Seward Peninsula, and then simulated present-day ground temperature dynamics and projected those into the future according to climate scenarios.

Topography and landscapes hydrology are key environmental controls on observed Arctic shrub expansion of the past three decades.

A new fast model based on hydrologic first-principles captures drainage from inundated ice-wedge polygons.

Joined by colleagues from around the world, Vladimir Romanovsky documents the current state of terrestrial permafrost for wide areas of the Arctic.

New insights are provided into drainage timing and flow patterns in inundated ice-wedge polygons based on fundamental hydrogeology

Image textural features and machine learning models can effectively identify broad regions of polygonal ground topography in the arctic using panchromatic imagery.

Opportunities emerge for leadership in the NGEE Arctic project and we welcome Katrina Bennett to her new co-lead responsibilities for permafrost hydrology.

Numerical experiment suggest that reliable projections of air temperature and total snowfall may not be sufficient to understand permafrost degradation.
