Ancient tropical rocks that now reside in the remote northern reaches of Canada tell the tale: about 716.5 million years ago the Earth lay bound in a layer of ice that limited life to eukaryotes. Strangely, this glaciation—history’s most extensive at 5 million years, say researchers at NSF and Harvard—occurred at about the same time that animals appear in the fossil record.

Scientists at Columbia’s Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments.

Engineers from the UCLA Henry Samueli School of Engineering and Applied Science have sped up the process of analyzing bacterial concentrations to under one hour, through the development of a new in-field, rapid-detection method.

A study led by Scripps Institution of Oceanography and multiple universities has concluded that southbound infragravity waves, created and driven by storms in the Pacific Ocean, may have been a key mechanical agent in the 2008 breakup of the Wilkins Ice Shelf.

An ultra-lightweight sponge made of clay and a bit of high-grade plastic draws oil out of contaminated water but leaves the water behind.

The bubbles in your champagne that appear to jump out of your glass and tickle your nose are exhibiting a behavior quite similar to the tiny bubbles found throughout the world’s oceans.

It’s been more than 200 years since Haiti was struck by a major earthquake, but the circumstances of yesterday's quake contributed to the great loss of life. The epicenter, just 10 miles from Port-au-Prince and a mere 6.2 miles underground, wreaked havoc on the country's capital. Also, a low degree of slippage between the Caribbean and North American plates, experts say, gave no indication that an earthquake of this magnitude was imminent.

More than 4,000 feet beneath the Pacific Ocean, a
submersible robot in May of this year captured a unique video of a deep-sea
eruption, allowing scientists to see for the first time the creation of a
material called boninite, which had previously been found only in samples at
least a million years old.

Hit-and-run attacks by sharks can be solved with a new technique that identifies the culprits by the unique chomp they put on their victims, according to a Univ. of Florida researcher. In a method analogous to analyzing human fingerprints, scientists can make identifications by precisely comparing shark bites to the jaws and teeth of the powerful predators.

Underwater robots take many forms, but few are stranger than MIT’s burrowing mechanism that apes the razor clam, one of nature’s best anchors. The robot can dig quickly and deeply, potentially locking whatever it is attached to—a sensing robot, for example—solidly to the seafloor.
