Waves Generated By Russian Meteor Recorded Crossing The US
2013-03-07 13:29:53

National Science Foundation A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States. The National Science Foundation- (NSF) supported stations are used to study earthquakes and the Earth's deep interior. While thousands of earthquakes around the globe are recorded by seismometers in these stations--part of the permanent Global Seismographic Network (GSN) and...

Russian Meteor Is The Largest Ever Detected By CTBTO’s Infrasound Sensors
2013-02-19 12:31:59

CTBTO Infrasonic waves from the meteor that broke up over Russia´s Ural mountains last week were the largest ever recorded by the CTBTO´s International Monitoring System. Infrasound is low frequency sound with a range of less than 10 Hz. The blast was detected by 17 infrasound stations in the CTBTO´s network, which tracks atomic blasts across the planet. The furthest station to record the sub-audible sound was 15,000km away in Antarctica. The origin of the low frequency...

Infrasound Study Reveals Why Some Homing Pigeons Get Lost
2013-01-31 12:35:04

Brett Smith for redOrbit.com — Your Universe Online Homing pigeons have been bred to find their way back to a home loft, and despite their reliability, some of these domestic birds are thrown off course from to time. In a new study, Jonathan Hagstrum, from the US Geological Survey (USGS), set out to find why pigeons released from a certain part of New York State always seem to have problems finding their way back home. Hagstrum´s findings, which were recently published in...

Adding the Ghost Sub to their experience, top haunts across the country give fear seekers good reason to proceed with caution. Canoga Park, CA (PRWEB) October 24, 2012 This year it is estimated that 20% of all Americans will visit some sort of haunted attraction grossing 400-500 million dollars in revenue. Over 3,000 haunted attractions and trails will attempt to draw in that 20% from their local population, but a few exceptional haunts perform at the top of their class getting recognized...

Earth Surface: A Giant Loudspeaker
2012-10-19 12:56:13

Brett Smith for redOrbit.com — Your Universe Online In the midst of an earthquake, buildings sway back and forth, terrain pops and locks, and the ground seems to shuffle underfoot. Acoustic scientists have shown in a new study that the Earth´s surface and atmosphere act as a giant loudspeaker. This “loudspeaker” soundtracks these geologic raves in both the audible range of hearing and in infrasound, or frequencies below the range human hearing can detect....

The Mechanics Of An Elephant's Voice
2012-08-03 05:40:41

April Flowers for redOrbit.com - Your Universe Online African elephants are known to communicate with infrasound - extremely low-pitched vocalizations - over a distance of miles. These infrasounds are at a very low frequency rate, fewer than 20 Hertz per second, and are generally below the threshold of human hearing. A new study, published in the August 3 issue of Science, shows that elephants rely on the same mechanism that produces human speech, and the vocalizations of other mammals,...

Image 1 - How Big Was The Fireball Over California And Nevada?
2012-04-25 01:06:44

A bright ball of light traveling east to west was seen over the skies of central/northern California Sunday morning, April 22. The former space rock-turned-flaming-meteor entered Earth's atmosphere around 8 a.m. PDT. Reports of the fireball have come in from as far north as Sacramento, Calif. and as far east as North Las Vegas, Nev. Bill Cooke of the Meteoroid Environments Office at NASA's Marshall Space Flight Center in Huntsville, Ala., estimates the object was about the size of a...

Scientists say that fish are being threatened by man-made noise pollution. The scientists reviewed the impact of noise made by oil and gas rigs, ships, boats and sonar on fish species around the world. They say that rather than live in a silent world, most fish hear well and sound plays an active part in their lives. The increasing noise pollution may severely affect the distribution of fish, as well as their ability to reproduce, communicate and avoid predators. "People always just...

Scientists from the Naval Research Laboratory at Stennis Space Center, MS, (NRL-SSC) and Washington, D.C., recently completed an investigation of the acoustic properties of the deep seafloor in the Gulf of Mexico. Scientists on the cruise measured the effects of geologic faulting on the efficiency of acoustic wave propagation. "Knowing the bottom loss-the amount of sound energy lost with each bounce off the bottom-affects how far away one can 'see' a target in the ocean using sound," said...
