    At the southern end of Madagascar lie four enormous wedge-shaped sediment deposits, called chevrons, that are composed of material from the ocean floor. Each covers twice the area of Manhattan with sediment as deep as the Chrysler Building is high. On close inspection, the chevron deposits contain deep ocean microfossils that are fused with a medley of metals typically formed by cosmic impacts. And all of them point in the same direction — toward the middle of the Indian Ocean where a newly discovered crater, 18 miles in diameter, lies 12,500 feet below the surface. The explanation is obvious to...

    An earthquake nearly 3,000 years ago may be the culprit in the mysterious disappearance of one of China's ancient civilizations, new research suggests. The massive temblor may have caused catastrophic landslides, damming up the Sanxingdui culture's main water source and diverting it to a new location. That, in turn, may have spurred the ancient Chinese culture to move closer to the new river flow, study co-author Niannian Fan, a river sciences researcher at Tsinghua University in Chengdu, China, said Dec. 18 at the 47th annual meeting of the American Geophysical Union in San Francisco.

The unusual object can be seen moving through the sky leaving a long tail behind that is characteristic of space debris or a meteorite burning up in the atmosphere. But after a few seconds a second round object separates from the main fireball and moves off in the opposite direction. UFO hunters have claimed the bright orb may have been some sort of escape pod from a crashing ship. However, others have said it is more likely to...

    The world’s oceans are now rising far faster than they did in the past, a new study says. The study found that for much of the 20th century — until about 1990 — sea level was about 30 percent less than earlier research had figured. But that’s not good news, scientists say, because about 25 years ago the seas started rising faster and the acceleration in 1990 turns out to be more dramatic than previously calculated.

"We found Middle Palaeolithic assemblages below and above the ash indicating the technologies being used at the time of the event. When the stone tool assemblages were analyzed from contexts above and below the ash, we found that they were very similar........We therefore concluded that the Middle Palaeolithic hominins survived the eruption and there was population continuity. This is not what would have been expected based on general theories that the Toba super-eruption decimated populations." Moreover, similar findings published by Christine Lane, et...

Xiaoping Yang of the Chinese Academy of Sciences, Louis Scuderi of the University of New Mexico, and their colleagues examined the patterns of dunes and depressions in the region and lake sediments, and they dated quartz from the region with a technique known as optically stimulated luminescence. They found that Hunshandake had deep lakes and rivers beginning some 12,000 years ago. "We're amazed by...

Let me start with an overview of oceanic pH (the measure of alkalinity/acidity, with neutral being a pH of 7.0). Many people think that the ocean has only one pH  everywhere. Other people think that the oceanic pH is different in different places, but is constant over time. Neither view is correct.First, here is a view of a transect of the north Pacific ocean...

The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period. The Younger Dryas lasted a thousand years and coincided with the extinction of mammoths and other great beasts and the disappearance of the Paleo-Indian Clovis people. In the 1980s, some researchers put forward the idea that the cool period, which fell between...

In fact, the poles are “much more stable” than climate scientists once predicted and could even be much thicker than previously thought. For years, scientists have suggested that both poles are melting at an alarming rate because of warming temperatures – dangerously raising the Earth’s sea levels while threatening the homes of Arctic and Antarctic animals. But the uncertainty surrounding climate change and the polar ice caps reached a new level this month when research suggested the ice in the Antarctic is actually growing. And...

Barnard’s Star, for instance, is roughly six light years away, a red dwarf that was the target of the original Daedalus starship designers back in the 1970s. But that distance is changing. If we were a species with a longer lifetime, we could wait about eight thousand years, at which time Barnard’s Star would close to less than four light years. No star shows a larger proper motion relative to...

    Sometimes we make that first dash into the ocean on summer vacation and happily announce, "It's warm as bathwater." But a new study based on ancient sediments collected off South America indicates that the tropical Atlantic Ocean really did hit temperatures as high as 107 degrees Fahrenheit back when dinosaurs ruled. The finding, reported Friday by researchers from the Woods Hole Oceanographic Institution during the annual meeting of the American Association for the Advancement of Science, also estimates that carbon dioxide made up as much as six times more of the atmosphere at that time than it does today.

The findings made by Tomohiro and the international research team help to account for this. “The total inventory of “observable” current surface water (that mostly occurs as polar ice, ~10E6 km3) is more than one order magnitude smaller than the estimated volume of ancient surface water (~10E7 to 10E8 km3) that is thought to have covered the northern lowlands,” said Tomohiro. “The lack of water at the surface today was problematic for advocates of...

Looking ahead to the future, there is no reason why such a freeze shouldn't happen again — and in ironic fashion it could be precipitated if ongoing changes in climate force the Greenland ice sheet to suddenly melt, scientists say. Starting roughly 12,800 years ago, the Northern Hemisphere was gripped by a chill that lasted some 1,300 years. Known by scientists as the Younger...

    (A few years back, Professor Stephen Oppenheimer wrote a book titled "Eden In The East" where he proposed that our culture flowed from east to west instead of west to east. Here's a rebuttal)Cultural diffusion from East to West? 2014/01/12 Oppenheimer’s theory is that “ … the roots of the great flowering of civilisation in the fertile crescent of the Ancient Near East lay in the sinking shorelines of Southeast Asia. The Sumerians and Egyptians themselves wrote about the skilled wise men from the East, a fact often dismissed as the embellishment of a fertile imagination.” Purely as an aside,...

    Researchers at Northwestern University have found evidence for a massive reservoir of water deep within the Earth's mantle. The reservoir, which is said to be three times the volume of the oceans on the surface, is contained within highly-pressurized rock known as ringwoodite. The scientists hope that their findings, recently published in the journal Science, can shed light on where Earth's oceans came from. THREE TIMES THE VOLUME OF THE OCEANS ON EARTH'S SURFACE The team, led by mineralogist Steven Jacobsen, used an array of 2000 seismometers to study how seismic waves generated by earthquakes move through the Earth's interior....

    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.Water is carried mantle by deep sea fault zones which penetrate the oceanic plate as it bends into the subduction zone.  Subduction, where an oceanic tectonic plate is forced beneath another plate, causes large earthquakes such as the recent Tohoku earthquake, as well as many earthquakes that occur hundreds of kilometers below the Earth’s surface.Seismic modellingSeismologists at Liverpool have estimated that over the age of the Earth, the Japan subduction...

    Scientists scanning the deep interior of Earth have found evidence of a vast water reservoir beneath eastern Asia that is at least the volume of the Arctic Ocean. The discovery marks the first time such a large body of water has found in the planet’s deep mantle. The finding, made by Michael Wysession, a seismologist at Washington State University in St. Louis, and his former graduate student Jesse Lawrence, now at the University of California, San Diego, will be detailed in a forthcoming monograph to be published by the American Geophysical Union.

    Explanation: Why do some places on Earth have higher gravity than others? Sometimes the reason is unknown. To help better understand the Earth's surface, sensitive measurments by the orbiting satellites GRACE and CHAMP were used to create a map of Earth's gravitational field. Since a center for studying this data is in Potsdam, Germany, and since the result makes the Earth look somewhat like a potato, the resulting geoid has been referred to as the Potsdam Gravity Potato. High areas on this map, colored red, indicate areas where gravity is slightly stronger than usual, while in blue areas gravity is...

    The Cimbrian flood (or Cymbrian flood) was a large-scale incursion of the North Sea in the region of the Jutland peninsula (Denmark) in the period 120 to 114 BC, resulting in a permanent change of coastline with much land lost. The flood was caused by one or several very strong storm(s). A high number of people living in the affected area of Jutland drowned, and the flooding apparently set off a migration of the Cimbri tribes previously settled there (Lamb 1991)... The Cimbri were a tribe from Northern Europe, who, together with the Proto-Germanic Teutones and the Ambrones threatened the...

    Asteroid sourced hydrogen and oxygen will literally and figuratively fuel expansion of the space economy by providing a locally sourced fuel resource that will change how industry operates in space. While existing satellites cannot be refueled directly today, space tugs fueled by asteroids that are currently being developed, will maneuver Geostationary satellites into their assigned orbit. Thus, keeping them operating and generating revenue far beyond their current life expectancy. Water from asteroids can also be used for a plethora of other applications beyond fuels in space. It can be consumed, used as a radiation shield for humans during deep space...
