USGS scientists are working to model shorebird habitat availability both today and in the future, given processes like sea-level rise, in an effort to support the efficient management of beaches for both people and nesting shorebirds.

Barnegat Bay residence times in days for (a) scenario T, only tidal forcing; (b) scenario TB, combined offshore hydrodynamic forcing; (c) scenario TBR, streamflow with combined hydrodynamic forcing; and (d) scenario TBRM, full suite with meteorological forcing

Composite aerial view of Sandwich Town Neck Beach. The imagery was obtained from an unmanned aerial system (UAS) flown by Peter Traykovski in February, 2015, a few days after winter storm Juno. The background topography is from USGS and U.S. Army Corps of Engineers lidar data, with missing-data areas shown in white.

Locations of the 97 beaches and barrier islands where our partners used the iPlover app to collect and record information on landcover characteristics at piping plover nesting locations during the breeding seasons of 2014-2016.

Split-beam (EK60) sonar image of bubbles (green) in the water column at a seep site overlooking Baltimore Canyon on the U.S. Atlantic margin. Although the bubbles appear to nearly reach the sea surface, the methane contained in the bubbles would have dissolved and been replaced by other gases by the time the bubbles rise several hundred meters.

Map showing the distribution of physiographic zones within the Buzzards Bay study area. The physiographic zone classification is adapted from Kelley and others (1998), and the zones are delineated on the basis of sea-floor morphology and the dominant texture of surficial material.
