Schematic showing the general setting of seeps on the US Atlantic margin and related processes, such as gas hydrate degradation, groundwater seepage, leakage through fractured rocks, or emissions from the seafloor overlying salt diapirs. Pockmarks shown in white, and the nominal updip limit of gas hydrate stability is represented by the dashed black line.

Photograph from a mounted time-lapse camera looking eastward along Barter Island’s north shore document how the coastal bluffs and beach changed during a single summer. The photograph shows a summer storm from the west eroding the beach (July 25, 2014).

Jen Suttles collects water samples from a salt marsh tidal creek (East Falmouth, MA) for laboratory analysis of total organic carbon.  These samples will be compared to data recorded by instrumentation deployed in an adjacent tidal creek as part of research efforts to quantify carbon dynamics in coastal ecosystems

The Salt Marsh Observatory at Sage Lot Pond in the Waquoit Bay National Estuarine Research Reserve serves as an important platform for research in coastal salt marshes. Infrastrucutre in this marsh allows researchers to access sites while maintaining habitat and platform health.

Researchers at the USGS study the long-term change of the beaches and dunes at Fire Island, NY.

 Sara Zeigler (USGS) uses the smartphone data collection app ‘iPlover’ to classify the landscape characteristics in an area immediately surrounding a piping plover nest (here, protected with a black mesh predator exclosure).

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. This photo shows an area on the Rockaway Peninsula where high quality shorebird habitat has been closed off to beach recreation.

The beach-dependent shorebirds project at the Woods Hole Coastal and Marine Science Center models current and future habitat availability for nesting shorebirds in an effort to map current and likely future habitat availability on a range of sites along the U.S. Atlantic coast.

USGS researchers collect repeat geophysical data from the nearshore at Fire Island, NY to study bathymetric change over time.

The U.S. Army Corps of Engineers’ Lighter Amphibious Resupply Cargo (LARC) survey vessel towed an Edgetech chirp 512i subbottom profiler mounted on a catamaran sled.

USGS scientist Jennifer Miselis stands on board the US Army Corps of Engineers' (USACE) Lighter Amphibious Resupply Cargo (LARC). USGS collaborated with USACE to analyze coastal change due to Hurricane Sandy. Miselis is preparing to deploy a Chirp sub-bottom profiling system with a towfish attached in between the pontoons to collect sub-seafloor geological data.
