3-D computer models aid research of Earth's core
November 29, 2006The work of a University of Alaska Fairbanks post-doctoral fellow will be included in an article appearing in the upcoming issue of the journal, Science.
The article reveals that scientists are now able to directly measure heat that moves from the molten metal of Earth's core into a region at the base of the mantle, a boundary located halfway to Earth's center, about 1,740 miles deep. Measuring heat deep inside the earth is important because the intense temperatures drive processes like the movement of tectonic plates.
For his contribution to the research, Michael S. Thorne, who holds a dual appointment with the Geophysical Institute and the Arctic Region Supercomputing Center (ARSC) at the University of Alaska Fairbanks, created 3-dimensional simulations of earthquakes, allowing scientists to see how seismic waves travel through the earth. These simulations are able to predict ground motion on earth's surface producing what is known as synthetic seismograms. The simulations of wave behavior assist scientists as they identify how material is moving inside the earth, specifically at the core-mantle boundary deep beneath the Pacific plate.
Thorne put in an impressive 70,000 computing hours on the ARSC IBM supercomputer, "Iceberg," for this project.

Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began.
Researchers can predict hurricane-related power outages
Using data from Hurricane Katrina and four other destructive storms, researchers from Johns Hopkins and Texas A&M universities say they have found a way to accurately predict power outages in advance of a hurricane.
Diverting sediment-rich water below New Orleans could lead to extensive new land
Diverting sediment-rich water from the Mississippi River below New Orleans could generate new land in the river's delta in the next century.
Cuts to Mississippi levees could build new land in sinking delta
Diverting sediment-rich water from the Mississippi River below New Orleans could generate new land in the river's delta in the next century that would equal almost half the acreage otherwise expected to disappear during that period, a new study shows.
Banking on outlier detection
Recent bank failures point to the continuing need for vigilance by regulators and investors. Now, a report in the International Journal of Operational Research, discusses the possibility of an early-warning system that spots the outliers before they fail.

Today Is a Good Day by New Model Army 2009 release, the 11th album from the legendary global underground cult band led by Justin Sullivan. Mostly written last autumn in the wake of the Wall Street collapse (an event celebrated in the white-hot opening title track), the recording was postponed by the sudden and unexpected death at Christmas of Tommy Tee, the band's long-time friend and manager. However, with another long-time friend Chris Kimsey (notable for his work with the Rolling Stones, Jimmy Cliff, Killing Joke and countless others) at the controls, the album is now finished - once again filled with unclassifiable music and challenging lyrical ideas. |
