NASA detects ocean inside Saturn moon

NASA's Cassini spacecraft and Deep Space Network have uncovered evidence Saturn's moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes.

NSIDC, NASA say Arctic melt season lengthening, ocean rapidly warming

The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.

Ocean food web is key in the global carbon cycle

Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to oceanographer David Siegel, director of the Earth Research Institute at UC Santa Barbara.

Study: Global warming felt to deepest reaches of ocean

In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed.

Is there an ocean beneath our feet?

Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth’s oceans to the upper mantle than previously thought.

Researchers quantify toxic ocean conditions during major extinction 93.9 million years ago

Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous short lived biotic events — typically marked by significant climatic perturbations — took place when oxygen concentrations in the ocean dipped episodically.

Underlying ocean melts ice shelf, speeds up glacier movement

Warm ocean water, not warm air, is melting the Pine Island Glacier's floating ice shelf in Antarctica and may be the culprit for increased melting of other ice shelves, according to an international team of researchers.

Scientists solve a 14,000-year-old ocean mystery

At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended — as mysteriously as it began — just a few hundred years later.

Europa's deep ocean may seep to the surface

Astronomers have found the strongest evidence yet that the ocean on Jupiter's moon Europa may consist of salty water, like our own. And, they say, that salty water appears to be making its way to the surface.

Mercury once had vast lava ocean

Mercury may once have had a large ocean of magma, Messenger data shows, shortly after its formation about 4.5 billion years ago.

DARPA to hide drones at the bottom of the ocean

DARPA is planning to build drones that would hibernate in deep-sea capsules for years before waking up when commanded and releasing their payloads into the sky.

Huge ocean fertilization project 'breaches geoengineering rules'

A project pitched to locals as a way to boost salmon stocks was in fact a major geoengineering effort that breaches UN rules, it's been claimed.

Ocean bacteria colonized land billions of years ago

Researchers at the University of Washington have determined that "some" microbial life migrated from the Earth's oceans to land some 2.75 billion years ago.

Winds high in stratosphere affect deep ocean currents

Evidence has emerged that changes in the winds high up in the stratosphere have a powerful effect on ocean currents a mile below the surface.

Ocean methane source explained

Scientists say they've finally established where the ocean's methane is coming from.

Ocean acidification disrupting food chains

Shellfish respond to increasing acidification in seawater - such as that produced by climate change - by producing lighter, thinner shells.

Garbage-eating drone destroys ocean pollution

Drones have been a hot topic in the media lately. Whether they’re for surveillance or combat, the idea of drones patrolling our airspace is one that’s not taken lightly by the public.

Cassini finds underground ocean on Saturn's moon Titan

NASA's Cassini spacecraft has come up with strng evidence that Saturn's moon Titan is hiding a layer of liquid water under its ice shell.

Video: This SeaOrbiter would make Captain Nemo jealous

The SeaOrbiter has yet to hit the water, but it's already being called a 21st-century version of Captain Nemo's Nautilus in honor of the classic novel "20,000 Leagues Under the Sea" penned by Jules Verne.

Plastic debris found littering ocean

There's far more little bits of plastic in the ocean than previous studies have indicated, according to new research.
