Scientists capture Earth’s “hum” on ocean floor

Researchers have successfully quantified Earth’s vibrational “hum” using seismic instruments on the bottom of the ocean. A new study determined at the ocean bottom the frequencies at which the Earth naturally vibrates, and confirmed the viability of using ocean instruments to study the phenomenon.

Dark fiber: Using sensors beneath our feet to tell us about earthquakes, water and other geophysical phenomena

Scientists have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.

Moon’s Crust Underwent Resurfacing after Forming from Magma Ocean

A research team took to the lab to recreate the magmatic melt that once formed the lunar surface and uncovered new insights on how the modern moonscape came to be. Their study found found that one of the great mysteries of the lunar body’s formation – how it could develop a crust composed largely of just one mineral – cannot be explained by the initial crust formation and must have been the result of some secondary event.

Groundwater recharge in the American west under climate change

Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research.

Scientists locate whistling space electrons’ origins

New research using data from NASA’s Van Allen Probes mission and FIREBIRD II CubeSat has shown that a common plasma wave in space is likely responsible for the impulsive loss of high-energy electrons into Earth’s atmosphere.

New Antarctic heat map reveals sub-ice hotspots

An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet.

Scientists may have solved mystery of rapidly rising Indian Ocean sea level

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

Scientists use seismic waves to measure tornado intensity

Seismic waves generated by tornadoes when they touch down could be used to measure a twister’s intensity, according to a new study that examined the May 2011 Joplin tornado. The findings could open the door to devising more accurate methods to study tornadoes from the ground.

The missing mass — what is causing a geoid low in the Indian Ocean?

In a recent study, scientists explored the reasons behind the existence of the Indian Ocean Geoid Low, a point of low gravity found just south of the Indian peninsula.

Secrets of hidden ice canyons revealed

In a new study, scientists have discovered huge canyons cutting through the underbelly of Antarctica’s ice shelves, meaning they may be more fragile than previously thought. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.
