Massive body of water discovered towards Earth's core - 3 times bigger than all oceans combined

Massive body of water discovered towards Earth's core - 3 times bigger than all oceans combined | Scuba & Underwater News | Scoop.it

A huge expanse of water trapped in a layer of the Earth's mantle could help explain the origin of our oceans.

 

A reservoir of water three times the volume of all the oceans has been discovered deep beneath the Earth's surface. The water is hidden inside a blue rock called ringwoodite that lies 700 kilometres underground in the mantle, the layer of hot rock between Earth's surface and its core.

 

The huge size of the reservoir throws new light on the origin of Earth's water. Some geologists think water arrived in comets as they struck the planet, but the new discovery supports an alternative idea that the oceans gradually oozed out of the interior of the early Earth.

 

"It's good evidence the Earth's water came from within," says Steven Jacobsen of Northwestern University in Evanston, Illinois. The hidden water could also act as a buffer for the oceans on the surface, explaining why they have stayed the same size for millions of years.

 

Jacobsen's team used 2000 seismometers to study the seismic waves generated by more than 500 earthquakes. These waves move throughout Earth's interior, including the core, and can be detected at the surface. "They make the Earth ring like a bell for days afterwards," says Jacobsen.

Here's Carl Sagan's original essay on the dangers of climate change

Here's Carl Sagan's original essay on the dangers of climate change | Scuba & Underwater News | Scoop.it

The Earth is a tiny and fragile world. It needs to be cherished.

1. More precisely, an impact crater 10 kilometers in diameter is produced on the Earth about once every 500,000 years; it would survive erosion for about 300 million years in areas that are geologically stable, such as Europe and North America. Smaller craters are produced more frequently and destroyed more rapidly, especially in geologically active regions.

2. The albedo is the fraction of the sunlight striking a planet that is reflected back to space. The albedo of the Earth is some 30 to 35 percent. The rest of the sunlight is absorbed by the ground and is responsible for the average surface temperature.

Seriously hard to believe Carl Sagan wrote about climate change in 1980.  New edition of his book just released with a foreword fromCosmos reboot host Neil deGrasse Tyson.

Christian Allié's curator insight, December 12, 2013 1:50 PM

......"""......

"""......"""

 

[ ..... ]

 

...  In our ignorance, we continue to push and pull, to pollute the atmosphere and brighten the land, oblivious of the fact that the long-term consequences are largely unknown. A few million years ago, when human beings first evolved on Earth, it was already a middle-aged world, 4.6 billion years along from the catastrophes and impetuosities of its youth. But we humans now represent a new and perhaps decisive factor. Our intelligence and our technology have given us the power to affect the climate. How will we use this power? Are we willing to tolerate ignorance and complacency in matters that affect the entire human family? Do we value short-term advantages above the welfare of the Earth? Or will we think on longer time scales, with concern for our children and our grandchildren, to understand and protect the complex life-support systems of our planet? The Earth is a tiny and fragile world. It needs to be cherished.
