The importance of freeze–thaw cycles for lateral tracer transport in ice-wedge polygons
A significant portion of the Arctic coastal plain is classified as polygonal tundra and plays a vital role in soil carbon cycling. Recent research suggests that lateral transport of dissolved carbon could exceed vertical carbon releases to the atmosphere. However, the details of lateral subsurface f...

A significant portion of the Arctic coastal plain is classified as polygonal tundra and plays a vital role in soil carbon cycling.

The model captures the physical effects of freeze–thaw cycles on lateral flow in polygonal tundra. The new modeling capability enables non-reactive tracer movement within subsurface. We utilized this new capability to investigate the impact of freeze–thaw cycles on lateral flow in the polygonal tundra.
