We monitor subsidence in Sherman Island (Sacramento–San Joaquin Delta) with InSAR.
- class="label">•
We use NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR)'s data.
- class="label">•
The study covers July 2009–Aug 2014, with data collected ~ every 6 weeks.
- class="label">•
Average subsidence rate is 1.3 ±/− 0.2 cm/yr, variable across the island.
- class="label">•
We ground truth InSAR with extensometer and previous power pole measurements.
