Biogeochemistry of low‐ and high‐centered ice‐wedge polygons in wetlands in Svalbard

Permafrost and Periglacial Processes, 2023
AbstractArctic wetlands are a globally significant store of soil organic carbon. They are often characterized by ice‐wedge polygons, which are diagnostic of lowland permafrost, and which greatly influence wetland hydrology and biogeochemistry during summer.

Ice-Wedge Polygons of Northern Alaska

1982
Ice-wedge polygons, commonly 5–30 m in diameter, are strikingly developed over the Arctic Coastal Plain of northern Alaska. Troughs over ice wedges that outline the polygons are a few centimeters to several meters wide. Centers of polygons are flat, high centered, or low centered in a continuum in which relief generally is several decimeters to a meter.
