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.

Cartogram maps provide new view of climate change risk

Scientists have developed cartograms — maps that convey information by contorting areas — to visualize the risks of climate change in a novel way.

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.

Stronger storms hamper ability of streams and rivers to clean up pollution

Freshwater streams and rivers naturally clean up some forms of pollution originating from urban and agricultural areas, but increased storm intensity reduces this ability.

Scientists counter threat of flooding on coral reef coasts

Scientists have developed a computer simulation tool to predict short-term flood hazards on coral-reef-lined coasts and to assess longer-term impacts from climate change. The assessments will give input to estimate societal or economic risk and damage from such flooding.

Scientists discover evidence of recent water flows on Mars

Planetary scientists have discovered a rare ‘esker’ on Mars – a ridge of sediment deposited by meltwater flowing beneath a glacier in the relatively recent past (about 110 million years ago), despite the widely-held view that the recent climate was too cold for ice to melt.

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.
