New Owl Species Discovered In Indonesia By Its Unique Whistle
2013-02-14 07:35:57

Lawrence LeBlond for redOrbit.com - Your Universe Online A new species of owl has been discovered in Lombok, Indonesia by two researchers just a few days apart from one another in early September 2003. But it was not the plumage that gave this bird away. The unique night song of the Rinjani Scops owl (Otus jolandae) caught the attention of these two scientists, offering evidence that the island of Lombok has its first recorded endemic bird species. Nearly a decade later, the first...

Volcano Controversy Settled Using Chemistry ‘Trick’
2013-02-12 15:01:41

Brett Smith for redOrbit.com - Your Universe Online Volcanic eruptions have been known to cause global cooling, although the extent of this cooling has been a topic of scientific controversy. Now a team of atmosphere chemists from the Tokyo Institute of Technology and the University of Copenhagen has devised a method for determining which historical cooling periods are the results of volcanic eruptions. When a large volcano erupts, it can propel gases high into the stratosphere where...

Roots Of Catastrophe Run Deep
2013-02-07 11:20:32

University of Utah Partly molten, Florida-sized blob forms atop Earth's core A University of Utah seismologist analyzed seismic waves that bombarded Earth's core, and believes he got a look at the earliest roots of Earth's most cataclysmic kind of volcanic eruption. But don't worry. He says it won't happen for perhaps 200 million years. "What we may be detecting is the start of one of these large eruptive events that — if it ever happens — could cause very massive...

New Type Of Volcanic Eruption Described By Scientists
2013-01-21 10:41:33

Brett Smith for redOrbit.com - Your Universe Online Neither explosive nor effusive–there´s a new type of volcanic eruption that was recently described in the latest edition of Nature Geoscience. According to the U.K. and New Zealand scientists who authored the description, volcanic pumice produced by the Macauley volcano in the southwest Pacific is the result of a previously unarticulated type of eruption. “By documenting the shape and density of bubbles in pumices...

Subduction Evidence From Billions Of Years Ago
2013-01-19 06:32:40

redOrbit Staff & Wire Reports - Your Universe Online Researchers for the first time have discovered evidence supporting the theory that the processes that act as catalysts for volcanic activity today are similar to those that occurred nearly four billion years ago. Writing in the journal Geology, Frances Jenner of the Carnegie Institution for Science and colleagues report that 3.8 billion-year-old volcanic rocks recovered from an island in southwestern Greenland support previous...

Scientists Compile Largest Database Of Major Volcanic Eruptions
2013-01-18 15:42:29

Lee Rannals for redOrbit.com — Your Universe Online Scientists have compiled a database detailing around 2,000 major volcanic eruptions that occurred over the last 18 million years. The open access database of Large Magnitude Explosive Eruptions (LaMEVE) will be able to provide crucial information to scientists and others involved in volcano research. Volcanic eruptions have been known to cause disruptions in air traffic, impact climate, and alter surrounding landscapes. Gaining a...

Earth’s Magma Mantle Melts Hotter Than Previously Thought
2013-01-10 10:10:41

April Flowers for redOrbit.com - Your Universe Online According to a new study by researchers at Rice University, the Earth's mantle magma melts far hotter and deeper in the Earth's core than previously thought, a discovery that will have lasting implications for our understanding of the planet's geophysical and geochemical properties. The research team, led by Rajdeep Dasgupta, put small amounts of peridotite under large pressures in a laboratory to determine that rock can and does...
