USGS researchers can study beach recovery by collecting repeat elevation profiles at Fire Island, NY.

USGS scientist Jackson Currie deploys a chirp sub-bottom profiler (in the center) from research vessel Parke Snavely. The chirp is attached to pontoons to keep the equipment from running aground in the shallow waters of San Pablo Bay, California.

Cores can contain sediment units deposited in different environmental settings. Core photos and X-rays illuminate how sediment units can have contrasting color and density.  

Scientists recover the Benthic OBservation camera Sled, or “BOB Sled,” onto the research vessel Parke Snavely

Colonies of “blade fire coral” that have lost their symbiotic algae, or “bleached,” on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae – all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer.

A colony of the soft coral known as the "bent sea rod" stands bleached on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae – all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer.

No, that is not a mound of snow sitting on a coral reef – it is a colony of bleached "brain coral" on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae – all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer.

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 late-summer extreme storm with waves crashing into the bluff (September 3, 2014).

Timeline of past drilling activities conducted by countries, private sector firms, government agencies, and academe that have helped to refine global gas hydrate estimates and possible future drilling and production testing

Airgun array aboard R/V Marcus G. Langseth

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).

Marinna Martini prepares to deploy a NIMBBLE from the R/V Connecticut south of Martha's Vineyard

A Sontek IQ ADCP measures depth and velocity of a salt marsh creek (Cape Cod, MA)

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.
