• USGS scientists collecting sediment vibracores in Grand Bay estuary from a boat in May 2016.

A 14-cm upland peat auger sediment core of a brown peat above fine tan silty sand was collected from the Grand Bay National Estuarine Research Reserve in May, 2016.

Ground-Penetrating Radar instruments are towed across land. Data from this instrument show underlying sediment layers within the dune and barrier island, which may reveal patterns of growth and erosion.

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.

We collect terrestrial (barrier island) and marine (nearshore and estuarine) sediment cores to ground-truth geophysical observations. These cores are used to understand the history of barrier island formation and erosion.

The impacts of extreme storms can be striking. Here, winter nor’easters eroded sediments from an artificial dune at Fire Island, New York and moved them onto the beach and shoreface. Such erosion created a steep vertical face, or scarp. Erosion and overwash are expected to increase on Fire Island with rising sea levels. 

Though often less intense than hurricanes, extratropical storms (e.g., nor’easters) occur more frequently and their impacts can be striking. Here, several years after Hurricane Sandy, winter nor’easters eroded sediments from an artificial dune at Fire Island, NY and moved them onto the beach and shoreface. Such erosion created a steep vertical face, or scarp.

The Florida Keys reefs have been experiencing a severe disease outbreak from 2014 to present called Stony Coral Tissue Loss Disease (SCTLD).

The USGS conducted UAS flights to map the Nauset Marsh and Coast Guard Beach areas of Cape Cod National Seashore on Tuesday, March 1, 2016. These are the first authorized UAS flights in the northeast region of the national park system, and were performed under a research permit according to FAA and DOI regulations.

Seafloor image at a deepwater (~1400 m water depth) seep site on the New England margin. Seafloor conditions here are well inside the pressure-temperature stability field for methane hydrate. Gas being emitted below the rock overhang has formed gas hydrate (the white ice-like material). Distinct bubbles are visible in the foreground. The red laser scale is 10 cm.
