Scientists walk on the beach beside a boardwalk that sits on an eroding bluff at the Rockaway Peninsula, New York. A new study investigates the geologic framework and how human modifications to the coast have influenced sediment availability on this margin.

USGS Research Geologist Jennifer Miselis will conduct shoreface geophysical surveys at the USACE Field Research Facility during DUNEX aboard the LARC, which is shown here being set up for the survey.

A geophysical instrument (chirp) is towed in the water (yellow instrument) from a floating sled to acquire information about the geology below the seafloor in Duck, NC as part of DUNEX. The USACE Field Research Facility can be seen in the background in the upper left corner.

In the background is the Research Vessel (R/V) Robert Gordon Sproul, operated by Scripps Institution of Oceanography (SIO).

A groin at Seven Mile Island, New Jersey traps sand and contributes to widening of the barrier beach. This illustrates how human modification and wave processes shape the beach. In May 2021, Andrew Farmer, Chelsea Stalk, and Emily Wei conducted a multibeam bathymetry survey offshore of Seven Mile Island, along the southern coast of New Jersey.

A UTV (utility task vehicle) parked in front of a beach scarp used to collect data that is used in cooperation with FWC, FWS, USGS, and USFSP to understand sea turtle nesting behavior in response to beach renourishment with the goal of advising engineers on how to develop more turtle friendly nourishment desig

Science crew from the USGS Pacific Coastal and Marine Science Center work on deployment of seismic streamer on deck of R/V Robert Gordon Sproul. Green cable is the hydrophone streamer and a "bird" is being attached to control depth in the water.

An Acoustic Doppler Current Profiler (ADCP) on the deck of the R/V Sallenger ready to be deployed in the water. The ADCP now sits on the bottom of the ocean off Madeira beach, Florida in 5m water depth.

Scientific divers BJ Reynolds and Hunter Wilcox prepare to lower an Acoustic Doppler Current Profiler (ADCP) into the water. The ADCP now sits on the bottom of the ocean off Madeira beach, Florida in 5m water depth.
