Exploring the Dynamics of the Active Layer and Near-Surface Permafrost across the North Slope of Alaska

NSF logoThis project is funded by the National Science Foundation


To develop remote sensing techniques using Interferometric Synthetic Aperture Radar (InSAR) to measure the active layer thickness


Tingjun Zhang is the PI, and Kevin Schaefer, Lin Liu (Stanford), and Howard Zebker (Stanford) are Co-Investigators.

Project Summary

InSAR measures the seasonal surface deformation due to the annual freezing and thawing of the active layer. We are developing and validating an algorithm that estimates the active layer thickness from the seasonal deformation.
