New Sandia Balloon-Borne Infrasound Sensor Array Detects Explosions

Infrasound_sensors.jpg

Danny Bowman, a Sandia National Laboratories geophysicist, launched a fleet of five solar-powered hot air balloons last year. They reached a height of 13 to 15 miles, twice as high as commercial jets, and detected the infrasound from a test explosion. Infrasound is sound of very low frequencies, below 20 hertz, which is lower than humans can hear, and can be used to monitor explosions, including those caused by nuclear tests. Bowman is also working with NASA to explore the possibility of sending these balloons to Venus and Jupiter.

Further Reducing Injections of Oilfield Wastewater Underground Can Prevent Larger Earthquakes

The new study shows that locations that experienced earthquakes are tied in proximity and timeliness to mass waste water injection sites. Further, the study indicates that tracking annual data on the injection well locations can help predict how corresponding earthquake activity will change. This new finding builds on previous studies showing that earthquake activity increases when wastewater injections increase.

S&T Helps Create the Standards Next USCG Cutter Polar Ice Breaker

S&T’s Office of Standards understood the need to gather in-depth data to determine how to construct the next-generation icebreaker. To do that, they needed to see, first hand, how changes to the current construct reacted to ice.

With French Grant to ‘Make Our Planet Great Again,’ This Scientist to Study Earth’s Outer Skin

Among the initial 18 scientists selected for French President Emmanuel Macron's "Make Our Planet Great Again" program is Louis Derry, professor of earth and atmospheric sciences in Cornell University’s College of Engineering and faculty fellow with the Atkinson Center for a Sustainable Future.

Mass Extinctions Remove Species but Not Ecological Variety

spikey-trio.jpg

Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall "functional" diversity--how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks. University of Chicago scientists documented this surprising trend in a study on extinctions published Jan. 5 in the Proceedings of the National Academy of Sciences.

Tulane University Names $1 Million Winner of Nitrogen Reduction Challenge

Tulane University awarded the $1 million grand prize for the Tulane Nitrogen Reduction Challenge to Adapt-N, a team from Cornell University that developed a cloud-based computer modeling system to predict optimum nitrogen application rates for crops using data on weather, field conditions and soil management practices.
