The robotic arm of the Jason, a Remotely Operated Vehicle (ROV), collects several stalks of black coral from the seafloor. Read more about how underwater vehicles help ocean scientists study deep-sea...
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 (...
Last week, Smithsonian research zoologists Dr. Jerry Harasewych and Dr. Martha Nizinski were in Curaçao looking for deep-sea marine gastropods and decapod crustaceans , respectively. I learned they...
The ocean is home to a phenomenal diversity of marine organisms. They have evolved to inhabit warm waters near the equator and the icy waters of the Earth’s poles. Marine life takes advantage of the...
Ocean scientists safely travel to deep-sea coral ecosystems up to 3,000 m (9,843 ft) below the ocean’s surface inside the Johnson-Sea-Link, a submersible owned and operated by the Harbor Branch...
Dr. Carole Baldwin, Smithsonian Curator of Fishes, and Adrien "Dutch" Schrier of the Curacao Seaquarium reflect the holiday spirit as they work off the coast of Curacao in the southern Caribbean.
Deep-sea corals scientist Dr. J. Murray Roberts photographed these living polyps from the Mingulay Reef Complex off Scotland in aquaria in 2010. Learn more about Roberts' work mapping deep-sea corals...
You’re out to sea on a 355 foot platform, and suddenly one end begins to slowly tip underwater. Should there be a call for evacuation? Are you sinking? Not if you’re on FLIP – the FLoating Instrument...
Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
This octopod is sometimes called a “Dumbo” octopod because its fins resemble the ears of Disney’s Dumbo the elephant. The video was recorded in 2003 on the Mid-Atlantic Ridge by the Russian manned...
Off the coast of North Carolina, Dr. Martha Nizinski and Johnson Sea Link pilot Phil Santos descend through the water column toward the target site. During this dive, Nizinski will observe and record...
A deep-sea octopus wraps itself around a submersible’s robotic arm 2,300 meters (7,546 feet) down in the Gulf of Mexico. "Most octopuses will let you get close, maybe even touch them, but normally...
Ships are well-known for their tiny rooms and tight quarters. But have you heard of a sea vessel that has toilets and sinks sticking out of the walls, and staircases and doors on the ceiling? This...
You never know where following your passions can take you. I came to the Smithsonian's National Museum of Natural History (NMNH) two years ago as a research intern after graduating with a Bachelor’s...
Come along as scientist Dr. Brendan Roark narrates a submersible dive to collect and study deep-sea corals. Roark studies deep-sea corals to understand the history of the ocean and past ocean...
The Chikyu allows scientists to gather and study data about seafloor sediments as soon as they are collected. After a powerful 9.0 earthquake triggered a devestating tsunami in Japan in March 2011 ,...
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...
Special ships called ‘icebreakers’ are needed to access some areas of the ice-covered Arctic Ocean .
