A team of Chinese researchers used artificial intelligence to scan millions of seismic recordings and identified six never-before-documented formations deep at the boundary between Earth's mantle and its liquid outer core. The structures sit roughly 1,800 miles below the planet's surface, in one of the most extreme and least understood environments on Earth. Temperatures at […] The post Chinese scientists find six unknown structures buried 1,800 miles beneath Earth's surface appeared first on American Almanac .
A team of Chinese researchers used artificial intelligence to scan millions of seismic recordings and identified six never-before-documented formations deep at the boundary between Earth's mantle and its liquid outer core. The structures sit roughly 1,800 miles below the planet's surface, in one of the most extreme and least understood environments on Earth. Temperatures at the mantle-core boundary swing by about 1,000°C, nearly 1,800°F, across a relatively thin transition zone where solid, slow-moving rock meets liquid metal. The researchers described the formations as "deep-seated scatterers" and "thermochemical piles," terms that refer to regions where the rock composition or temperature differs sharply from the surrounding mantle…Open
SUBSCRIBE for more vids~ Summary: Scientists found a lost river system beneath Antarctica, proving the continent was once vastly different. See what lies under the ice. This video explores the recent Antarctica discovery of ancient valleys and ridges that remained preserved for millions of years. We examine how this lost river system challenges previous assumptions about how ice erodes the landscape. This content is intended for anyone interested in geology, earth science, and the history of our planet. By analyzing this prehistoric landscape, researchers are gaining new insights into the stability of the current Antarctic ice sheet. Understanding these conditions helps us better model climate history and predict how polar regions may…
SUBSCRIBE to the channel for more vids Summary: A massive subglacial river system has been mapped beneath the Antarctic ice sheet. See how modern radar technology reveals this complex landscape. Researchers recently utilized ice penetrating radar to survey 32,000 square kilometers of the eastern Antarctic ice sheet. This detailed mapping identifies a river network spanning nearly 1,000 miles, fundamentally changing our understanding of what lies beneath the surface. This video is for anyone interested in geology, glaciology, or the latest scientific discoveries regarding the Antarctic ice sheet. By analyzing these new surveys, we can better comprehend the stability and behavior of the ice. The data confirms a surprisingly complex…
Several communities in Los Angeles remain on high alert for earthquakes after fault lines have shown the highest stress level in history. John Vidale, USC dean's professor of Earth sciences, joins “Katie Pavlich Tonight” to discuss. #california #earthquakes #faultlines "Katie Pavlich Tonight" offers a conservative take on the day’s events while welcoming all viewpoints. The goal: cutting through left-right bias in pursuit of plain facts and honest analysis.
The priceless titanosaur fossil was discovered in 1985 during an expedition to Antarctica, but was tucked away for decades before being found recently.
Northern lights could be seen further south than usual with the expected arrival of three coronal mass ejections, according to NOAA's Space Weather Prediction Center.
Scientists lost their instruments within Antarctica’s most dangerously unstable glacier, though not before getting a glimpse at the warming waters underneath.
AI:Scientific efforts to drill through Antarctica's highly unstable Thwaites Glacier have ended in failure after researchers lost their essential instrumentation deep within the ice. Despite the loss of equipment, the mission provided critical data regarding the temperature and movement of the warming waters circulating beneath the glacier, offering a brief glimpse into the processes driving its instability.Open
