EPA divers from Atlanta place this instrument in Charleston Harbor in order to monitor currents and better predict sand movement for a harbor deepening project.
A scientist, Chris Reddy from Woods Hole Oceanographic Institution, collects oil-laden "sand patties" on a Louisiana beach two years after the oil spill. Watch a video of Chris Reddy talking about...
Brian Skerry, an award winning photographer for National Geographic, explores the underwater world searching for the perfect photo. But getting that photo is never easy. Read more from Brian about...
At the Smithsonian Tropical Research Institute in Panama, Dr. Wayne Sousa (right) studies how gaps in the canopy caused by lightning help mangrove forests regenerate. More about mangroves can be...
The remotely operated vehicle ROPOS recovers a volcano monitor from NOAA’s New Millennium Observatory on the Juan de Fuca Ridge, off the coast of the Northwest United States. The station was set up...
Dr. Martha Nizinski holds a specimen of a fan sponge ( Phakellia sp. ) collected at a deep-sea coral study site off the coast of South Carolina. Deep-sea corals and sponges provide structure for a...
Diving to survey, sample, and manage marine life takes a great deal of skill and knowledge. This diver is sampling the seafloor, also known as the benthic zone. This kind of sampling is important for...
Auster gets ready to study fish predators at Gray’s Reef National Marine Sanctuary off the coast of Georgia.
A cable connects a remotely operated vehicle (ROV) to a ship at the surface, where it is operated by a pilot onboard the ship. The cable can extend for miles into the deep sea.
Starksia blennies, small coral reef fish, have been well-studied for more than 100 years. But Smithsonian scientists discovered that what were thought to be three species of the fish are actually 10...
In 2009 Dr. Vecchione served as Chief Scientist on a six-week expedition to the Mid-Atlantic Ridge for the Census of Marine Life. He is shown here aboard the expedition ship, NOAA’s Henry B. Bigelow.
Ice divers use a quadrat to study the density of creatures living on the underside of Arctic ice floes. A quadrat is a standardized square used to take sample measurements that allow researchers to...
The mauve stinger’s ( Pelagia noctiluca ) name in German means “night light,” referring to the jelly’s reddish coloring and its bioluminescence, the display of light by a living creature. Unlike a...
Recent Antarctic expeditions have documented climate-induced changes to emperor penguin habitats and impacts on how the penguins feed, breed, and raise their young.
Dr. Robert Ballard poses with an unmanned submersible, like the one he used when locating and exploring the wreck of the RMS Titanic. A veteran explorer, former U.S. Navy Commander, and professor of...
Smithsonian Zoologist Dr. Clyde Roper (rear) and museum specialist Mike Sweeney examine the mantle of a dead giant squid. Everything we know about giant squid comes from studying specimens found...
Deep-sea coral beds are true biodiversity hotspots. It’s urgent that we study these extreme environments because we know so little about them, because they are important communities for so many deep-...
