Grain of sand takes record for Earth's oldest rock
Independent Record
A team of geologists at the University of Wisconsin, Madison, recently announced that they have measured the age of a tiny crystal from Australia, and found it to be the oldest rock ever discovered on Earth. This little blue grain of sand is 4.37 billion years old, which gives us some amazing clues about how the Earth's crust originally formed.

Geologist: Undersea volcanoes could complicate MH370 wreckage retrieval
MSN News
The recovery of MH370 and its black box is going to be an extremely difficult task as geologists believe the debris from the Malaysian Airlines aircraft could be lying above a giant undersea chain of volcanoes whose complex terrain has barely been charted, reported The Sydney Morning Herald. To make matters worse, the only Australian vessel capable of charting depths of 3,000 meters, the RV Southern Surveyor, had been decommissioned in December, the daily said.

Chesapeake Bay impact crater affecting sea level rise
MyEasterShoreMD
Scientists say sea level rise is occurring at a faster pace in the Chesapeake Bay region than the global average, and the dramatic formation of the Bay itself is a significant reason why. About 35 million years ago, a meteorite collided with Earth near the current location of the mouth of the Bay. The impact left a crater more than 55 miles wide, setting events into motion that eventually led to the formation of the Bay about 3,000 years ago.

Researchers say dormant Yellowstone supervolcano may never erupt again
The Daily Mail
It is believed to be the world's biggest volcano, and if it erupted, much of the U.S. would be covered in ash. However, researchers believe the massive supervolcano beneath Yellowstone National Park in the U.S. — which researchers recently found was 2.5 times bigger than they thought — could actually soon be dead.

There may be a 2nd massive ocean deep beneath the Earth's surface
Smithsonian
Deep within the Earth, staggering pressures mix with high temperatures to compact regular materials into exotic minerals. Under these extreme conditions, one familiar mineral is transformed into a material called ringwoodite. While ringwoodite has been found before, researchers in Brazil found a sample that had an even greater surprise locked inside.

Seismic shift: How the Good Friday earthquake of 1964 changed science
Anchorage Daily News
On March 27, 1964, the Great Alaska Earthquake released more energy than all other North American quakes since. Its magnitude, 9.2, made it the second most powerful earthquake ever recorded. In the words of Peter Haeussler, U.S. Geological Survey research geologist, the whole world jiggled "like a giant water balloon." But something else also shifted that day: Science.

LiDar mapping could save lives before the next mudslide
Motherboard
Almost a week after the mudslide in Snohomish County, Wash., 25 people are known to have died and 90 people are still missing . To prevent something on this scale from happening again, some are asking how to make better use of the new information and maps made with LiDAR — aerial mapping that uses laser pulses fired at the ground from a passing aircraft. LiDAR can be accurate down to just a few inches, a vast improvement over old topographical surveys done based on aerial photography that, due to tree cover, could only be guesses.

Seismic technology reveals huge underwater coal deposits
Ferret
Undersea resources previously thought inaccessible look like promising future energy reserves of energy that could power Britain for centuries, according to a former Newcastle University professor of energy. Professor Dermot Roddy said that there may be between three trillion and 23 trillion tons of coal buried in Britain's North Sea, although geologists have not yet discovered the exact scale of the deposits, the International Business Times reports.

Sandboxes bring maps to life
Juneau Empire
A generation of Americans, now adults, grew up playing in sandboxes. The structures, which fostered the creative energy of thousands of future architects, geologists and geographers have fallen out of popularity in the past few decades, largely disappearing from playgrounds around the nation. But sandboxes are making a comeback — thanks in part to the work of a professor of geological data visualization at University of California Davis, Oliver Kreylos.

Geologists study Yilgarn's western crust
Science Network WA via Phys.org
A group of geologists working for the Geological Survey of Western Australia has confirmed a long-standing belief that most of the Yilgarn Craton has a similar crustal architecture. Structural geologist Ivan Zibra says they studied the Youanmi Terrane, which constitutes the western portion of the Yilgarn Craton. He says large shear zones are easily detectable from magnetic geophysical images that have been available for a long time.

Scientist sees no evidence that Gulf Stream is slowing down
Providence Journal
The Gulf Stream is part of what scientists call the “Atlantic thermohaline circulation,” which conveys heat from the tropics to the North Atlantic. As the warm surface water cools, it sinks to the ocean floor and then travels southward before returning to the tropics and heating up again. Some scientists have speculated that a changing climate could lead to warmer ocean temperatures, increased freshwater runoff from glaciers and reduced salinity — all of which could slow the thermohaline circulation and further upset the climate.
