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.

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.
