Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
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...
How do you make science sing? Just ask a couple of female scientists to sing about their research interests and their passion is quickly conveyed in a quirky little tune. Informative, inspiring, and...
Researchers can study ocean acidification in the lab by rearing organisms in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently. It's common, for...
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-...
The pre-industrial American landscape was once rightly described as a place where “the deer and the antelope roam.” On land, we take it for granted that the plant-eating deer and antelope far...
I’m a high school student interested in pursuing marine science. I have loved the ocean since I was 3 feet tall and only getting my feet wet at the beach. I’m a senior in high school, and over the...
For more than two centuries, Boston Harbor has been a dumping ground. In 1773, colonists famously dumped shiploads of tea to protest taxes. But in recent decades, the harbor has received less tea and...
Dr. Peter Auster gets ready for a dive to study the ecology of fish predators at Gray’s Reef National Marine Sanctuary off the coast of Georgia.
Researchers in Moorea use a variety of tools to collect organisms. Some are simple, everyday items like buckets and brushes, and some are…a little stranger. Here, two researchers use a “yabbie pump”...
Scientists from the Integrated Ocean Drilling Program (IODP) collect sediments drilled from Earth’s crust. This marine research program supported by 24 countries is increasing our understanding of...
A reconstruction of a new fossil beluga relative, Bohaskaia monodontoides , described by Smithsonian scientists, is in the foreground. Its living relatives, the beluga and narwhal, are illustrated...
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.
Scientists on the tiny island of Moorea, in the Pacific, are gathering one of every life form large enough to pick up with tweezers. They're on a quest to build a detailed catalog of the entire...
Chilean and Smithsonian paleontologists study several fossil whale skeletons at Cerro Ballena, next to the Pan-American Highway in Atacama Region, Chile, in 2011. The fossils were discovered when the...
Dr. Amy Baco-Taylor observed corals like these on her first submarine dive to a deep-sea coral bed off the coast of Hawaii. They include primnoids, zoanthids, and Gerardia . The high density and...
Filmmaker and National Geographic Explorer James Cameron on March 25, 2012, became the first human to complete a solo submarine dive to Challenger Deep , an undersea valley in the Mariana Trench of...
Save Our Seas scientist Alison Kock tags a Great White Shark ( Carcharodon carcharias ) to gather data about their movements off the coast of South Africa. More about the great white shark can be...
