Special ships called ‘icebreakers’ are needed to access some areas of the ice-covered Arctic Ocean .
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...
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...
Take a tour of the Alvin, a three-person submersible that allows scientists to explore the depths of the ocean. This is an excerpt from the full Deep Ocean Explorers video. More about deep ocean...
The submersible Alvin carries scientists to the deep ocean, where they encounter amazing creatures and views of deep ocean life. Explore more in the Deep Ocean Exploration section .
A hybrid underwater vehicle combines the best features of an ROV (remotely operated vehicle), which is connected to a ship in order to transmit data and video feeds, and an AUV (autonomous underwater...
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-...
Smithsonian researchers are using this five-person submersible to study the biodiversity of the deep reefs of Curaçao in the southern Caribbean. Read about their adventures in the Summer in a Sub...
This autonomous operated vehicle, known as an ABE (autonomous benthic explorer), will map sites where seafloor earthquakes have occurred—enhancing our understanding of these catastrophic events.
Travel to a world of perpetual night--the deep ocean hydrothermal vents near the Galapagos Rift where life thrives around superheated water spewing from deep inside the Earth. Discovered only in 1977...
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.
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...
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...
On World Oceans Day - June 8th, 2012 - the Living Oceans Foundation hosted a live web-based conversation between Sylvia Earle at the Smithsonian's National Museum of Natural History and a team of...
Ice divers Katrin Iken (left) and Elizabeth Siddon are about to descend through a hole in the Arctic ice and into the frigid world below.
Ocean conditions change every hour of every day. Tides, currents, and winds are constantly in flux. NOAA’s real-time data helps huge ships navigate safely under bridges and around obstacles. Explore...
Hidden beneath Arctic ice is a world few have ever seen. Take the icy plunge with a team of ice-loving scientists.
The Autonomous Underwater Vehicle (AUV) SeaBed, shown here as it is about to be deployed, has been used to survey deep-sea fishes and coral habitats. Learn more about how underwater vehicles study...
