Seamounts may serve as refuges for deep-sea animals that struggle to survive elsewhere
Feast and famine on the abyssal plain
Animals living on the abyssal plain, miles below the ocean surface, don't usually get much to eat. Their main source of food is "marine snow"—a slow drift of mucus, fecal pellets, and body parts—that ...
Ancient ocean chemistry: Effects of biological oxygen production 100 million years before it accumulated in atmosphere
(PhysOrg.com) -- Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE), the ...
World's most extreme deep-sea vents revealed
Scientists have revealed details of the world's most extreme deep-sea volcanic vents, 5 kilometres down in a rift in the Caribbean seafloor.
California seafloor mapping reveals hidden treasures
Science and technology have peeled back a veil of water just offshore of California, revealing the hidden seafloor in unprecedented detail. New imagery, specialized undersea maps, and a wealth of data from ...
Deep-sea robot, caught in underwater avalanche, yields new scientific insights
Exploring the deep sea, and especially submarine canyons, is a risky business. The floors of many submarine canyons are periodically scoured by fast-moving underwater avalanches known as "turbidity currents." ...
Oceanic crust formation is dynamic after all
Imagine the Earth's crust as the planet's skin: Some areas are old and wrinkled while others have a fresher, more youthful sheen, as if they had been regularly lathered with lotion.
Seafloor research expedition features live online video feed
UC Santa Cruz hydrogeologist Andrew Fisher is leading an expedition on the research vessel (R/V) Atlantis this summer to explore fluid flow and microbial habitats deep within the ocean crust. His team is ...
Researchers map out ice sheets shrinking during Ice Age
A set of maps created by the University of Sheffield have illustrated, for the first time, how our last British ice sheet shrunk during the Ice Age.
Chikyu sets a new world drilling-depth record of scientific ocean drilling
Scientific deep sea drilling vessel Chikyu sets a world new record by drilling down and obtains rock samples from deeper than 2,111 meters below the seafloor off Shimokita Peninsula of Japan in the northwest ...
Research reveals bottom feeding techniques of tagged humpback whales in Stellwagen Bank Sanctuary
New NOAA-led research on tagged humpback whales in Stellwagen Bank National Marine Sanctuary reveals a variety of previously unknown feeding techniques along the seafloor. Rather than a single bottom feeding ...
Scientists Explore Origins of 'Supervolcanoes' on the Sea Floor
(PhysOrg.com) -- "Supervolcanoes" have been blamed for multiple mass extinctions in Earth's history, but the cause of their massive eruptions is unknown.
Seafloor carpet catches waves to generate energy
