Close-up of the interface between polyps of the mountainous star coral, Montastraea faveolata, and black-band disease (BBD), Florida Keys. Behind the black band is white coral skeleton remaining after the polyps have died.

Scientists at the USGS St. Petersburg Coastal and Marine Science Center study coral reef ecosystems. This coral, Orbicella annularis, was photographed in the Florida Keys during field work on coral disease.

A close-up of an eroded ocean dune scarp. The dune scarp is about 5 foot tall, with visible layers that were created as the dune was naturally building from wind.

A sand overwash fan on the back side of a dune near Shinnecock Inlet, Long Island, NY, 2010, with the overwash area labeled. The sand has already been cleared from the road. If you look at the background, you can see new sand has been added to the beach on the seaward side of the dune, creating a new, higher, dune crest.

A human-made seawall of riprap rock exposed by dune erosion. Small seawalls are created using large rocks (riprap) at the dune toe to fortify the dune, reduce dune erosion from elevated water levels and storms, and help to protect property. Over time, these seawalls may become covered by natural dune growth, but high-water events could re-expose them.
