This USGS vessel acquires single-beam bathymetry in shallow nearshore environments. We acquire repeat bathymetry surveys over multiple years and compute changes in bathymetry, thus allowing us to identify hotspots of erosion and deposition on short timescales.

Stop sign at the end of School House Hill Rd in Turner, Maine near USGS gaging station 01055500 on the Nezinscot River.

Map showing the change in modern sediment thickness in meters between 1996-1997 and 2011 offshore of Fire Island. Green areas indicate accretion and red a

Map showing the tracklines and grab sample sites of the 2014 and 2015 geophysical surveys offshore of the Delmarva Peninsula.

Storm induced erosion of marsh shorelines can provide significant quantities of sediment to the bay altering the deposition patterns.

Box-cores provide a relatively undistributed look into the recent past to help better understand the processes contributing to sediment deposition and erosion.

Surface sediments will be analyzed for various physical parameters that will be used as initial conditions in hydrodynamic and sediment transport models.

Flood maps from Our Coast, Our Future showing Stinson Beach today (slide 1); with a 50-centimeter sea-level rise (slide 2); and when an annual storm strikes in addition to 50-centimeter sea-level rise (slide 3). Green patches are low-lying areas prone to flooding.

Relative seagrass biomass in West Falmouth Harbor, MA, under current and potential future nitrogen loading scenarios. Seagrass biomass increases in western (seaward) portions of the harbor while eastern (landward) areas see new colonization by seagrass.
