Using SAR/InSAR to Capture Water Dynamics at the Great Dismal Swamp Refuge
Average radar intensity over the Great Dismal Swamp Refuge (GDSR) in North Carolina and Virginia has a close relationship with changing groundwater levels. Using PALSAR and RADARSAT2 Interferometric Synthetic Aperture Radar (InSAR) observations, the FWS estimated surface water level changes over the GDSR with repeat satellite radar imagery. This state-of-the-art research was done by Dr. Jinwoo Kim and Dr. Zhong Lu at Southern Methodist University with funding support by the U.S. Geological Survey and local logistical support by the FWS.
