The structure of the Earth beneath our feet has been fascinating to members of the scientific community recently, and it turns out it’s far more complex than people initially thought. First, we learned of the news that there’s a massive ocean beneath the Earth’s crust which contains more water than all of the seas on the surface. Now, another study has been published which has taken an in-depth look at the geology beneath the southern hemisphere. The new research, published in Science Advances, has found evidence that an entire ocean floor actually runs the length around the core.

It's an ancient formation that could provide more insight into the structure of the planet beneath our feet. Geologist Samantha Hansen and her colleagues from the University of Alabama led the research. They observed the structure by using 15 monitoring stations under the ice of Antarctica, mapping the waves from earthquakes. Doing this allowed them to analyse the structure of the Earth below the surface, including the ultra-low velocity zones where waves moved much slower. "Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought," Hansen said. "Analyzing [thousands] of seismic recordings from Antarctica, our high-definition imaging method found thin anomalous zones of material at the CMB everywhere we probed," geophysicist Edward Garnero from Arizona State University also said. "The material's thickness varies from a few kilometers to [tens] of kilometers. This suggests we are seeing mountains on the core, in some places up to five times taller than Mt. Everest." "Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet," Hansen added. Have your say in our news democracy.

It feels like there have been staggering science stories emerging every other day recently, all of which have blown our tiny little minds. First, there was the discovery of a terrifying black hole pointing right at us, then there was a huge hole found in the sun and a missing continent found after going missing for 375 years. Now, people are only just realising that there’s a massive ocean hidden under the Earth’s crust. It turns out there’s a huge supply of water 400 miles underground stored in rock known as 'ringwoodite'. Sign up to our new free Indy100 weekly newsletter Scientists previously discovered that water is stored inside mantle rock in a sponge-like state, which isn’t a liquid, solid or a gas, but instead a fourth state. The scientific paper titled ‘Dehydration melting at the top of the lower mantle’ was published in 2014 and laid out the findings. "The ringwoodite is like a sponge, soaking up water, there is something very special about the crystal structure of ringwoodite that allows it to attract hydrogen and trap water," said geophysicist Steve Jacobsen at the time. "This mineral can contain a lot of water under conditions of the deep mantle,” added Jacobsen, who was part of the team behind the discovery. He added: "I think we are finally seeing evidence for a whole-Earth water cycle, which may help explain the vast amount of liquid water on the surface of our habitable planet. Scientists have been looking for this missing deep water for decades." Scientists made the findings at the time after studying earthquakes and discovering that seismometers were picking up shockwaves under the surface of the Earth. From that, they were able to establish that the water was being held in the rock known as ringwoodite. If the rock contained just 1 per cent water, it would mean that there is three times more water under the surface of the Earth than there is in the oceans on the surface.
