Acoustic backscatter intensity data are an indication of the relative hardness or softness of the sea floor, which is closely related to sediment texture and cohesion. The map shows acoustic backscatter intensity of the sea floor in the Buzzards Bay, Massachusetts.

Underwater photograph off Molokaʻi Hawaiʻi, showing some of the impacts of land-based pollution, such as terrestrial sediment, on coral reefs: burial by sediment, algal overgrowth, and coral bleaching.

A black-bellied rosefish (Helicolenus dactylopterus) peaks out of the Lophelia coral. Behind the fish, a squat lobster (Eumunida picta) hangs upside down from a coral branch.

Perspective view of seafloor offshore of Half Moon Bay, showing scarp (arrows) along the eastern strand of the San Gregorio fault zone. Rocks are notably upwarped and folded adjacent to the fault.

Fish like this Atlantic Roughy (Hoplostethus occidentalis) congregate near deep-sea corals (background is Lophelia pertusa coral).

A cleaner shrimp (Plesionika sp.) with vivid blue eyes rests in a coral thicket next to a red soft coral (Anthomastus agassizii).

Extreme storms can drastically increase water levels and wave energy causing a breach, or complete erosion of the island itself. Hurricane Sandy created a breach in the Otis Pike High Dunes Wilderness Area at Fire Island National Seashore in NY.

Hurricane Sandy leveled dunes and moved eroded sediment from the dunes and beach across the island and into the estuary (Great South Bay) at Fire Island, NY.

USGS scientist Nancy Prouty collects samples from a CTD. A CTD is package of electronic instruments that measure conductivity, temperature, and depth of water.
