Seasonal InSAR thaw subsidence and frost heave time series in central and western Spitsbergen, Svalbard
We used Sentinel-1 Synthetic Aperture Radar Interferometry (InSAR) to measure the ground surface displacements in the permafrost landscape of Svalbard. The InSAR products document thaw subsidence and frost heave related to the seasonal active layer thawing and freezing in 2017. The displacement time...
