Sampling seawater every 4 hours for a period of 72 hours required the team to work during the early hours of the day. Left to right: Chris Gallagher (Pacific Coastal and Marine Science Center), Kim Yates (St.

Thirty-five years after the data were originally collected as part of a study of glacial geology of the western Gulf of Maine, USGS seismic and sampling data are being used to assist coastal communities in locating offshore sand resources for mitigating coastal erosion.

An adult piping plover. The piping plover is a small migratory shorebird listed as endangered in Canada and the U.S. Great Lakes, and threatened throughout the remainder of its U.S. breeding and winter range. Recent surveys indicate that there are only about 8,000 adults in existence.

The light blue areas on this map of the Port of Los Angeles could flood during a 100-year storm with no sea level rise, according to CoSMoS forecasts. The port handled about $270 billion of cargo in 2015.

According to CoSMoS forecasts, large parts of Long Beach, California, could flood during an intense El Niño storm (light blue areas).

Several factors affect sea cliff erosion including rain, rock strength, cliff toe height, wave energy, and coastal slope. 

The colored bands on this map of La Jolla, California, illustrate how far cliffs could erode in different sea level rise scenarios, according to CoSMoS forecasts.

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 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. 

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