Single cell microbes in the most remote portions of the ocean floor dating back to days when dinosaurs roamed the Earth are indeed alive. But not by much.

Baaaaaaaaaaaaaaarely alive. Which is a scientific term. Each “a” signifying how much closer to complete nonexistence it is.

Yet still, as Dr. Malcolm teaches us… life finds a way.

Røy and colleagues from Denmark and Germany surveyed red clays buried deep in the Pacific Ocean, along the equator and into the North Pacific Gyre current system. From the research R/V Knorr, they drilled core samples 92 feet into the ocean floor, dating to the time of the dinosaurs, and tested the cores with oxygen sensors. They found that organisms live in the deepest parts of these sediments and that they’re using oxygen for respiration — only incredibly slowly. The deeper the sediments, the less food and oxygen is present, and the less oxygen is used up, too. These organisms have not had access to a fresh food supply since their burial, 70 to 86 million years ago.

The finding could gives new insight into life on other planets. Now that we have an idea of just how durable life in on this particular rock we can have some hope that it could survive in a harsh environment elsewhere across the stars.

Shipwreck hunters have located an unusual object at the bottom of the Baltic Sea and will be heading out in May to find out what it really is.

Sonar readings show that the mysterious object is about 60 meters across, or, about the size of a jumbo jet. And it’s not alone. Nearby on the sea floor is another, smaller object with a similar shape. Even more fascinating, both objects have “drag marks” behind them on the sea floor, stretching back more than 400 feet.

“Could this be the Star Wars Millenium Falcon, a plug to an inner world or a marine version of Stonehenge?” asks CNN’s Brooke Bowman:

Located off the eastern coast of Australia, the clusterwink snail (Hinea brasiliana) uses a luminescent shell-flashing defense when its shell is tapped or when it detects predators nearby. Scientists think that this could either be a technique for attracting predators of the predator or perhaps a trick to scare them away. Recent experiments have shown that some crabs are frightened away by bioluminescent glowing creatures.

“When threatened, fingernail-sized H. brasiliana generates pulses of bioluminescent light from a single spot on its mushy body. The light pulses are variable, lasting as short as 1/50th of a second to as long as a few seconds. But the opaque shell diffuses only the blue-green color of light it generates — and no other color — like a highly selective frosted light bulb.”

According to our most recent studies, fears that we are the last generation to see coral reef due to the rising acidification of our waters is unfounded. This has been a fear raised by climate change studies which suggest CO2 concentration could jack up the pH balance of the seas and kill off marine life.

There is a whole ton of science on Matt Ridley’s awesome blog but here is the money shot:

In conclusion, claims of impending marine species extinctions driven by increases in the atmosphere’s CO2 concentration do not appear to be founded in empirical reality, based on the experimental findings we have analyzed above.

We are safe! Hooray!

No word on if we can just affect the pH balance enough to create monster fish or open a crack in an Arizona lake releasing thousands of blood-thirsty piranhas, in 3D.

The last time we saw census results this weird, Betty White was talking about swapping out calculator batteries to power a crotch massager.

Marine scientists have announced the 80% completion of a comprehensive ocean census and the results are predictably freaking bizarre. Check out a full slideshow at Discover Magazine’s 80beats blog.

Who does the mysterious Yacht belong to? Authorities in the Redington Beacharea of Florida were left scratching their heads Wednesday when this unmanned craft arrived on the sand. The $1,000,000 craft was never registered after it was sold by the previous owner 2 years ago, leaving the police to wonder who the new owner might be and what might have happened to them.

Police hope that the owner will report the craft as missing… if he wasn’t lost at sea.

Could it be Atlantis? Lost’s mystery island in the sideways universe? Either way, there are some sunken islands at the bottom of the Caribbean Ocean.

During their six weeks in the waters north of Venezuela and west of the Antilles, the experts from the University of Greifswald analysed rock samples from depths of more than 1,000 metres.

The “Meteor” crew then used echo sounding to measure the ocean floor, an exercise which revealed significant differences in depth compared to current marine charts.

In fact, some of the underwater mountains listed on charts did not exist at all, while other areas thought to be flat showed rises of up to 1,000 metres, geologist Martin Meschede said.

The team’s biggest surprise came from the samples they dredged from the ocean floor, which showed stones that could only have come from very shallow depths.

The scientist also believe that the islands were volcanic. No word on if “volcanic” means a nuclear bomb exploded, therefore resetting the timeline.

Did you wake up today thinking that ocean wasn’t a festering tub of death, disease and decay?

Welcome… to Germ Island!

When plants and animals near the surface of the ocean die, they decay and gradually fall to the seafloor. This dead matter can clump together with sand, soot, fecal matter and other material to form what is called “marine snow,” so named because it looks like tiny bits of white fluff. Marine snow continuously rains down on the deep ocean, feeding many of the creatures that dwell there.

A group of scientists studying marine snow found that these clumps, or aggregates, may act as island-like refuges for pathogens, the general term for disease-causing organisms or germs, such as bacteria and viruses. (The “island” term comes from the comparison of the existence of pathogens on marine snow with the way insects, amphibians and other creatures establish homes and persist on remote islands in the oceans.)

The scientists are evaluating the degree to which aggregates made up of this decaying organic matter provide a favorable microclimate for aquatic pathogens. These “refuges” seem to protect pathogens from stressors, such as sunlight and salinity (amount of salt in the water) changes, and from predators. They also might provide sources of nourishment for the pathogens.

See nature? This is what happens when you leave your oil laying around the ocean floor of 35,000 years!

California scientists found two massive asphalt domes on the sea floor, most likely the result of oil deposits made thousands of years ago.

“It was an amazing experience, driving along…and all of a sudden, this mountain is staring you in the face,” said Christopher M. Reddy, director of WHOI’s Coastal Ocean Institute and one of the study’s senior authors, as he described the discovery of the domes using the deep submersible vehicle Alvin. Moreover, the dome was teeming with undersea life. “It was essentially an oasis,” he said, “almost like an artificial reef.”

What really piqued the interest of Reddy — a marine geochemist who studies oil spills — was the chemical composition of the dome: “very unusual asphalt material,” he said. “There aren’t that many opportunities to study oil that’s been sitting around on the bottom of the ocean for 35,000 years.”

This is why we can’t keep anything nice on this sea shelf!

A remote controlled vehicle has discovered the deepest hydrothermal underwater vent on record 3.1 miles deep in the Cayman Trough in the Caribbean. Entitled “black smokers” the vents pump a black, iron sulfide compound into the ocean. The compound is hot enough to melt lead.

Locke is strangely unaffected by the news.
