Observations of phase changes coincident with geomorphic features

Abstract

This paper presents preliminary results showing phase changes in ERS interferograms which appear to show differential penetration depths or clay swelling/shrinking resulting from changes in soil moisture. What is more, these signals appear to correlate spatially with the location of geomophologic features, in this instance glacial deposits. This paper presents the observations and discusses the idea that such InSAR signals could aid in the identification of geomorphic features and even indicate their differing sedimentological composition.
