Traveling aboard the Charles W. Morgan , a 173-year-old whaling ship on its 38th Voyage, I’m struck by its paradox: this vessel which spent years chasing and killing whales is now helping us to study...
Smithsonian squid expert Dr. Clyde Roper collaborated with National Geographic to attach this Crittercam to the head of a sperm whale, hoping to get footage of the whale’s favorite prey—giant squid...
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...
Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
The remotely operated vehicle ROPOS recovers a volcano monitor from NOAA’s New Millennium Observatory on the Juan de Fuca Ridge, off the coast of the Northwest United States. The station was set up...
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...
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 .
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...
Marine biologist Mette Kaufman measures the temperature of a recently-drilled ice core . Variations in temperature at different points of the ice core provide information about the living conditions...
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...
Leatherback sea turtles ( Dermochelys coriacea ) are listed as critically endangered by the IUCN Red List of Threatened Species. The primary threats to leatherbacks are interactions with fisheries...
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 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 (...
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...
A Coral Reef Watch satellite monitors the temperature of the world’s oceans. When ocean waters get too hot, corals release the microscopic algae that provide them with color and, more importantly,...
This video, produced by Waterlust, shows how the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) uses drifters to collect important data about the ocean...
