#Strong After Sandy USGS Science Supporting the Department of Interior’s Response Landscape change from storms impacts humans and habitat USGS science expands our understanding of processes Mapping, measuring, and modeling build knowledge Collaboration enhances impact of science
Landscape change from storms impacts human infrastructure Barrier-island breach at Mantoloking, NJ
Landscape change from storms impacts natural habitat Marsh loss at Blackwater NWR Homes on edge of Forsythe NWR, NJ
Elevation change at Seaside Heights, NJ Mapping, measuring, and modeling landscape change Maps provide a detailed snapshot of landscape change Measurements identify physical forces causing change Models synthesize maps and measurements to inform decision-making Water level at Lindenhurst, NY Inundation probability (Cat. 2), Assateague Island, MD/VA
Expanding our understanding How do storms impact bays, flooding, and water quality?
2009 Mapping reveals long-term changes New mapping of marshes and estuaries 2013 Assateague Island National Seashore, MD Oceanside beach Estuary 300 feet
Measuring storm surge, waves, and landscape change Measurements describe physical processes Rapid deployment gage (waves, water level) Acoustic altimeter (seabed elevation) Assateague Island NS, MD Chincoteague NWR, VA Bottom platform (waves, water level, sediment movement, water quality)
Modeling provides science for decision-making Vulnerability assessment of shoreline during Sandy Forsythe NWR, NJ 5 miles High wave attack Low wave attack
Balancing flood protection with natural processes in bays Modeling provides science for decision-making Study showed that small breaches did not increase mainland vulnerability to storm flooding 05 Nov May 2009 Barrier-island breach at Fire Island, NY
Testing landscape configurations: new breaches Modeling provides science for decision-making
Collaboration enhances impact of science Gateway NRA, NY Forsythe NWR, NJ Assateague Island NS, MD & Chincoteague NWR, VA Our goals: collect physical data understand vulnerability and sustainability of coastal features provide science for informed decision-making Partnering between DOI agencies
