The bright, brilliant swirls of blue and green seen from space are a phytoplankton bloom in the Barents Sea. Phytoplankton can bloom like this, rapidly growing and reproducing, because of a sudden...
Dive through the zones of the ocean to the deep ocean bottom, where many strange species live, and there are many yet to be discovered. Explore them in the Deep Ocean Exploration section.
This is the world’s first unmanned, underwater robot—or “glider”—to cross an ocean basin, the pioneering Scarlet Knight . The robotic glider, also known as RU27, can dive to depths of 200 meters (660...
Views of each sonar beam appear on the left side of this computer screen image while the path being mapped by the ship appears on the right. These 3-D color images enable ocean scientists to locate...
Submarine pilot Bruce Brandt secures ARMS (Autonomous Reef Monitoring Structures) to the submersible Curasub off the coast of Curacao. In shallow water, SCUBA divers can place these biodiversity-...
This illustration shows how Scarlet Knight , the first unmanned, underwater robot or glider to cross an ocean basin, faced an entire fleet of fishing ships, equipped with nets, threatening the glider...
The spiral-tufted bryozoan ( Bugula neritina ) is being studied for a potential Alzheimer's disease and cancer drug -- but it's not the bryozoan that makes the chemical. The chemical, found in the...
Doing scientific research on a ship isn't always easy. On top of having to live and sleep on a boat on the water, you have to fit all your scientific equipment onboard—and make sure it continues...
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.
The first underwater robotic vehicle—or “glider”—to cross an ocean is the centerpiece of a new exhibit at the Smithsonian. Rutgers University professor Scott Glenn explains that the technology is now...
Success! A so-called "dumbo" octopod is chased and finally captured by a suction device on the ROV, skillfully operated by a pilot on the ship above.
Ever since fourth grade I’ve wanted to explore the creatures and landscapes of the deep ocean in a submersible. It took awhile, but I finally got my chance this summer as part of the Deep Reef...
