Resilience of Wetlands and Lagoons to Hurricane Sandy Impact

Submitted by Anonymous (not verified) on

The study goal is to document the damage and response of coastal ecosystems, including wetland and maritime forests, marshes, and submerged aquatic vegetation, to Hurricane Sandy. In reaching that goal, we will produce maps and remote sensing technologies for identifying those coastal resources that are most vulnerable to degradation and propose methods for resource management mitigation before irreparable loss.

Hurricane Sandy Surge and Marsh Dieback

The USGS National Wetlands Research Center (NWRC) located in Lafayette, Louisiana, is using remote sensing analyses to assess the impact of Hurricane Sandy on wetland areas by using before and after image data of coastal New Jersey.  Radar data from TerraSAR-X and COSMO X-band collected before and after the storm will be used to produce a series of surge extent maps. These radar-based maps will document the extent of elevated salinity surge flooding and define the duration of the surge, which is critical for assessment of wetland resource damage.
