Reefs provide protection from waves and wave-driven flooding. A snapshot from the simulation of wave-driven flooding and island overwash for an annual storm at the Republic of the Marshall Islands is shown.

First arrival times of contaminants at each location (lighter colors indicate longer time since the storm) for conditions observed during Hurricane Florence (top), and two hypothetical events: one with smaller rainfall (middle) and another with a different post-storm wind pattern (bottom).

 Coastal storms can severely alter the topography and ecosystems along heavily populated coastal regions. Seamless integrated elevation data for both land and submerged areas in Barnegat Bay, New Jersey, are fundamental to coastal planning of the northeastern U.S. Atlantic coast.

Storm and sea level rise scenario models, like the one shown here, can be used to explore the future. This model shows what Dauphin Island may look like 10 years from now if storms become stronger and more frequent (Passeri and others, 2018).

Gas hydrate (orange material) and gas bubbles near the seafloor in the northern Gulf of America. As the methane bubbles are emitted, a rind of gas hydrate immediately forms around some of them. If more bubbles continue to feed from below, gas hydrate forms.

SEABed Observation and Sampling System (SEABOSS) (center image) and the MiniSEABOSS (right) designed for rapid, inexpensive, and effective collection of seabed imagery (photographs and video) as well sediment samples from the coastal/inner-continental shelf regions.

The distribution of sediment textures within the study area. The bottom-type classification is from Barnhardt and others (1998) and is based on 16 sediment classes. The classification is based on four sediment units that include gravel (G), mud (M), rock (R), and sand (S). If the texture is greater than 90 percent, it is labeled with a single letter.

Scientist surveying the presence and behavior of birds at Pelican Island, Alabama. The CMHRP is working with personnel within the Ecosystems Mission Area on this project to identify how physical characteristics of barrier islands influence use by wintering shorebirds.

Three-dimensional model of Chimney Bluffs, New York along Lake Ontario created from low-altitude digital images collected from an unmanned aerial system (UAS).

This model shows what Dauphin Island, Alabama, may look like under moderate storms but with increasing rates of sea level rise (Passeri and others, 2018).

Streamflow on land is modeled with the hydrological model and then coupled with the ocean model. This figure shows comparison of water level between observed data (red) and a smoothed model output at the North East Cape Fear River.

Geologic sections (C-C', D-D', and E-E') illustrating the general distributions and thicknesses of seismic stratigraphic units and major unconformities in the Martha’s Vineyard and Nantucket study areas.

Coastal wetland ecosystems in Jamaica Bay, New York, provide important ecosystem services along the highly urbanized Atlantic coast.

A WHCMSC and WHOI team recovered six intermediate period ocean bottom seismographs from the continental slope offshore New England in Georges Bank. The instruments had been deployed for about ten months to record background, ambient seismic noise.
