This chart depicts the continuous movement of water between the land, the ocean, and the atmosphere. Lophelia pertussa and other deep coral reefs foster high biodiversity in an otherwise apparently barren area of the ocean. Scientists have been able to study rainforests, tropical reefs, and desert environments for many years but deep water reefs are only now being studied. The water cycle depicts water moving through the atmosphere and on and under the surface of the earth. Did you know that a human can live for a month without food, but less than one week without water? University of Alberta geochemist Graham Pearson holds a diamond used in a previous study that found oceans' worth of water deep inside the Earth. Previously, geophysicists had debated about whether there could be water in the transition zone. The diamond has a bumpy surface, sculptured by corrosive fluids in the Earth's mantle on its way to the surface.
That grain was made of ringwoodite a€” a form of the green mineral peridot that has never before been found on Earth, except in meteorites from space. But he and his colleagues probed the ringwoodite in the diamond with different kinds of light and looked for the signature of water. The layers of Earth above and below the transition zone, called the upper and lower mantles respectively, are each known to be "a desert for water," Pearson said.
Although scientists hadn't acknowledged until recently that the planet's water might make these kinds of underground voyages, it makes sense, Pearson added. The water now known to exist deep in Earth may help scientists better understand major geological processes.
Ringwoodite is a form of the mineral found on Earth's surface as peridot (the birthstone for the month of August) or olivine. The grain of ringwoodite became trapped in a diamond that has kept it preserved under high pressure. The diamond, a bumpy, dirty brown stone, just three millimetres wide, eventually ended up in the gravel at the bottom of a shallow river in Mato Grosso, Brazil, where it was scooped up by artisan miners in 2008.


Back at the University of Alberta, his graduate student John McNeill examined the rock using an instrument called a Raman microscope in the hopes that it might contain a calcium-rich mineral that would provide information about how old the diamond was.
The instrument belonged to Enrica Nestola, who happened to walk into the lab while McNeill was puzzling over what he was seeing. Nestola "is one of the handful of people in the world who would have known instantly what that was and identified it as ringwoodite," Pearson said. Pearson, who is a Canada Excellence Research Chair in Arctic Resources, added that the story illustrates the importance of basic and not just applied research, since scientists often make major discoveries "almost by chance" while looking for something completely different. A cross-section of Earth shows the location of ringwoodite, which makes up approximately 60 per cent by volume of the lower transition zone.

Perhaps the broadest protection we could offer would be to make them part of a Marine Protected Area and only allow scientists to enter the area to study it.
While all of these environments have much to offer us in terms of biodiversity and potential medical or commercial products, the Lophelia reefs are perhaps more important right now because less is known about them. He was a co-author of the new study that provides more evidence of how water is recycled deep within the Earth. Analysis of a mineral grain trapped inside it suggests that it came from surroundings that were about one per cent water, report researchers led by University of Alberta geochemist Graham Pearson. That's because, like a diamond itself, it can only be made under extremely high pressures like those found so deep inside the Earth that they are inaccessible to humans. Their analysis showed the sample contained 1.5 per cent water by weight, suggesting that the transition zone where it formed is about one per cent water.
That's because huge amounts of water from the depths of the Earth are constantly being spewed by volcanoes into the oceans and atmosphere.


In fact, the grain trapped inside the diamond likely started its life as an ordinary grain of olivine on a plate at the bottom of the ocean, Pearson said. The diamond eventually transported it up to Earth's surface via a type of volcanic rock called kimberlite, which can erupt very quickly from extreme depths. The diagram also shows how water gets transported down to those depths, and how diamonds and water move back to the surface.

Given the high diversity of such reefs, what steps do you think should be taken to protect them? This level of protection would mean that the reefs couldn’t be enjoyed by tourists or used commercially by fisherman. Please note that comments are moderated and published according to our submission guidelines.
Another protection would be to limit reef usage to certain times of the year or to a particular volume of people using the reef during a time period. Compared to other diverse environments such as tropical rainforests, tropical coral reefs, and desert ecosystems, how would you rate the importance of protecting deep water coral reefs? This would make the reefs more available to be enjoyed and used commercially yet offer them more protection than they currently have.
