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...
A number of questions have inspired marine ecologist Stuart Sandin to head to the coral reefs of the Line Islands . Sandin works at the Scripps Institution of Oceanography at the University of...
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...
NOAA’s New Millennium Observatory (NeMO) was set up to study geologic, chemical, and biologic interactions along the mid-ocean ridge system. Learn more about NeMO and watch a video about underwater...
Alvin, a human occupied vehicle (HOV), returns to the ship after a deep ocean dive to a seamount .
Smithsonian Zoologist Dr. Clyde Roper (rear) and museum specialist Mike Sweeney examine the mantle of a dead giant squid. Everything we know about giant squid comes from studying specimens found...
Diving to survey, sample, and manage marine life takes a great deal of skill and knowledge. This diver is sampling the seafloor, also known as the benthic zone. This kind of sampling is important for...
Dr. Candy Feller is framed by the roots of a mangrove tree on Panama’s Pacific coast. Mangrove trees grow particularly large in this area. More about mangroves can be found in our Mangroves featured...
Oceanographer and executive director of Oceana Europe , Xavier Pastor, led the Baltic Sea expedition. The crew covered more than 7,000 nautical miles and completed more than 130 dives to collect...
In 2009 Dr. Vecchione served as Chief Scientist on a six-week expedition to the Mid-Atlantic Ridge for the Census of Marine Life. He is shown here aboard the expedition ship, NOAA’s Henry B. Bigelow.
Scientists describe the amazing bioluminescent creatures they encounter as they descend into the deep--siphonophores, ctenophores, and viperfish--in this Smithsonian/History Channel "Deep Ocean...
Imagine you’re an alien seeing Planet Earth for the first time. What do you see from your spacecraft? A blue planet with over 70% of its surface covered by ocean. From space it’s obvious how...
Christian McDonald, the Scientific Diving Safety Officer at the Scripps Institution of Oceanography, tows a surface float at Millennium Atoll in the South Pacific.
The pre-industrial American landscape was once rightly described as a place where “the deer and the antelope roam.” On land, we take it for granted that the plant-eating deer and antelope far...
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.
GEOMAR scientist Armin Form works at his lab during a long-term experiment on the effects of lower pH, higher temperatures and "food stress" on the cold-water coral Lophelia pertusa . In a previous...
My father once told me that the world is divided into two kinds of people: those who believe that the world is divided into two kinds of people and those who don’t. Wherever you come down on this...
Save Our Seas scientist Alison Kock tags a Great White Shark ( Carcharodon carcharias ) to gather data about their movements off the coast of South Africa. More about the great white shark can be...
