Deep below the ocean’s surface is a mysterious world that takes up 95% of Earth’s living space. It could hide 20 Washington...
Using a drill, a team removes a chunk from the thick Arctic ice. Small samples are taken from where the ice meets liquid seawater. The ice is then melted for analysis.
The world beneath the Arctic ice is magical, but cold. Divers have to tolerate temperatures of 30 degrees Fahrenheit (about -2° Celsius.) To stay warm they wear thermal undergarments and use special...
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”...
Microbes are some of the most important organisms in the sea. These miniscule organisms provide an important link in the food web between the dissolved nutrients in the ocean and larger organisms...
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...
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...
Studies along the Northwest Atlantic Ocean shelf break- the transition from continental shelf to slope- by researchers from Woods Hole Oceanographic Institution and Rutgers University are revealing...
The Baltic’s waters are so frigid that the sandy seabed was often frozen during Oceana's 2011 expedition. The divers’ underwater cameras had to be put on automatic settings to take photos, as their...

Deploying ARMS (Autonomous Reef Monitoring Structures) is tricky in the deep sea, where SCUBA divers can't place and secure them to the floor with their hands and a hammer. Researchers with DROP (...
If you think only men can helm research vessels to get their hands dirty and study ocean currents, you're wrong. This short film follows the mostly-female scientists of the R/V Knorr research ship on...
Scientists journey to the isolated island of Moorea on a quest to catalog every life form big enough to pick up with tweezers—from mountaintop to seafloor. Get up close and personal with researchers...
A time-lapse video shows researchers from the Smithsonian's National Museum of Natural History and Smithsonian's Tropical Research Institute racing to excavate the fossil of an extinct toothed whale...
If there had been room to stand up, there would have been a standing ovation. As it was, the five of us on the submersible Curasub clapped and cheered when the first three deep-reef ARMS (Autonomous...
