Bycatch, the name given to fish and other ocean animals that are caught unintentionally, is a huge problem. Scientists and fishermen are joining forces to design new nets that catch only the targeted species,...
Sea turtles may have survived the planetary changes that killed the dinosaurs,...
If there had been room to stand up, there would have been a standing ovation...
Scientists from the Integrated Ocean Drilling Program (IODP) collect sediments...

A fleet of underwater floats called Argo is deployed at more than 3,000 spots around the world. The floats transmit information about water temperature, salinity, and pressure which scientists use to...
Algae, like all organisms, normally grow in balance with their ecosystems, limited by the amount of nutrients in the water. But sometimes, certain species of algae reproduce so rapidly that they...
NOAA is working with students across the globe to place floating buoys throughout the ocean through their Adopt a Drifter Program . The buoys will drift with the help of ocean currents and record the...
The research submersible Alvin uses bright lights to illuminate the dark seafloor. Built in 1964, it has made more than 4,400 dives. It can carry two scientists and a pilot as deep as 4,500 meters (...
When he was 10 years old, Stephen Cairns lived in Cuba where he kept a collection of butterflies and sea shells. When his family moved to Louisiana, he could bring only one of the collections with...
Researchers launch one-meter-tall plastic drifters into the Gulf of Mexico in 2012. Over 300 of these drifters were released and their location information was sent to researchers every five minutes...
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...
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.
Special ships called ‘icebreakers’ are needed to access some areas of the ice-covered Arctic Ocean .
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 (...
Scientists met the robotic glider Scarlet Knight about halfway along its journey of scientific exploration from the United States to Spain, discovering that barnacles were growing on the glider’s...
Searching for useful chemicals, marine scientists grow bacteria associated with deep-sea coral on nutrient agar to identify the bacteria and test their metabolic and biochemical capabilities. Some...
The sea's largest fish has been a mystery until recent decades. Thanks to electronic tags, researchers are uncovering some of the secrets of the whale shark ( Rhincodon typus Smith, 1828 ). One...
Curaçao, an island in the southern Caribbean is the site of the Smithsonian's Deep Reef Observation Project (DROP) . Researchers are using a submarine to study and collect specimens from the hard-to-...
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-...
Great White Sharks are stealthy hunters and the secret is in their skin. Shark skin is covered by tiny flat V-shaped scales, called dermal denticles, that are more like teeth than fish scales. These...
Have you ever seen a creature so unusual? This fish (22 cm long) is called a sea toad and studying them requires luck and the opportunity to descend into the deep waters where they live. Last week Dr...
Expedition data went to the Arctic Ocean Diversity database of the Census of Marine Life to establish a baseline that will help to document change in the poorly known Arctic Ocean. Scientist Kevin...
