B.C. fish farms damage environment, former judge finds
( 12/04)
Aquaculture is damaging the marine environment of British Columbia, and some practices may be illegal according to an independent inquiry conducted by a former judge of the B.C. Supreme Court.

New Details Of Earth's Internal Structure Emerge From Seismic Data
( 11/30)
About 1,800 miles beneath the surface, Earth's internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the core and the mantle may not be as sharply defined as scientists once thought. By analyzing earthquake waves that bounce off the core-mantle boundary, researchers have found evidence of a thin zone where the outermost core is more solid than fluid.

Scientists Find Hot Activity Under Arctic Ice Cap
( 11/28)
Deep below the frozen surface of the Arctic Ocean, scientists aboard a U.S. Coast Guard icebreaker discovered a searing caldron of activity, including numerous underwater volcanoes and deep-sea hot springs that may harbor previously unknown marine organisms.

Much Gold, Silver, Other Metals Lie Undiscovered In Saudi Arabia
( 11/27)
Oil may not be the only valuable commodity buried beneath the sands of Saudi Arabia. Ohio State University geologists have located new areas of potential metal deposits, based on the analysis of more than 2,100 known occurrences of gold, silver, copper, and other metals in the western third of the Saudi peninsula.

Small, Mountain Rivers Play Big Role In Ocean Sediment
( 11/26)
Shallow streams that wind through the mountains of New Zealand and Taiwan carry more sediment into the ocean than giant rivers like the Amazon or the Nile, according to Ohio State University geologists.

Antarctic sea floor contaminated by human waste near bases
( 11/19)
Outwardly pristine Antarctic seascapes are contaminated with untreated sewage and parts of the seabed are littered with junk ranging from dumped vehicles to beer cans, a government report said Friday.

Massive Magma Layer Feeds Mt. Vesuvius, And May Hold Clues To Eruptions, Researchers Report In Science
( 11/16)
Seismic data suggest the presence of a 400 kilometer square-wide reservoir of magma located eight kilometers below the famous Mt. Vesuvius volcano in Italy, according to a report by Italian and French researchers in the 16 November issue of the international journal, Science.

Earthquake Studies: Fault Moving Faster Than Believed
( 11/14)
Scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., and the University of California, Los Angeles, have concluded that earthquake fault zones in California's eastern Mojave Desert are moving in different ways than they expected.

Work is progressing on China's mammoth project to dam the Yangtze River
( 11/14)
Li Dongfeng feels a "historical responsibility" to build the Three Gorges Dam, the Chinese government's vast project to tame the Yangtze River.Li, a power station technician, is part of an army of 25,000 people working on the 60-story-high dam. It will be the world's biggest once work is done in 2009, with a reservoir that stretches 550 kilometers (350 miles) across central China.

Research Season Will Feature Use Of Sophisticated Technologies To Map Antarctica
( 11/12)
Researchers plan to map the surface of the vast Antarctic ice sheet with airborne radar, measure the movement of the Earth's crust beneath the ice with Global Positioning System transceivers and deploy buoys to explore the waters off the Antarctic Peninsula when the U.S. Antarctic Program's 2001-2002 research season gets underway next month.

Many of world's lakes face death, expert warns
( 11/12)
Many of the world's freshwater lakes face death by pollution, resulting in catastrophe for the human populations that depend on them, an environmental expert warned on Monday.

First glimpse inside a sunspot
(BBC news 11/6)
By analysing sound waves travelling inside the Sun, a US team of scientists has produced the first detailed image of what goes on inside a sunspot.

Researchers Use Tiny Bubbles To Determine Formation Temperatures For 300 Million Year Old Rocks
( 11/6)
The central Appalachian basin in West Virginia and western Maryland has been exploited for oil, natural gas, and coal over many years. Now, a Virginia Tech doctoral student is searching for tiny pockets of fluid that will provide information about ancient times and how sandstones associated with these natural resources formed in this basin.

Wealth Of New Species Discovered From The Abyssal Plains Of The Atlantic Ocean
( 11/1)
Preliminary findings from an expedition last year to the deep-sea of the Angola Basin are revealing a wealth of new information on biodiversity in the poorly known depths of the south Atlantic Ocean.
