Arlington VA (SPX) Dec 15, 2004Scientists have discovered evidence of microbial activity in a rock glacier high above tree line in the Rocky Mountains, a barren environment previously thought to be devoid of life. Shutdown Of Circulation Pattern Could Be Disastrous: Researchers 
Champaign IL (SPX) Dec 15, 2004If global warming shuts down the thermohaline circulation in the North Atlantic Ocean, the result could be catastrophic climate change. The environmental effects, models indicate, depend upon whether the shutdown is reversible or irreversible. |

NASA Tracks Impact Of Trees And Insects On Carbon Dioxide Levels
Moffett Field CA (SPX) Dec 15, 2004Winds and changing climate converted parts of Oklahoma, Kansas, Colorado and Texas into a giant 'dust bowl' in the 1930s. In response, the 1937 'Shelterbelt Project' involved the planting of trees to reduce erosion and provide relief from the biting winds that blew soil from farms and drove people west to California. Research Points To New Theory Driving Evolutionary Changes 
Dallas TX (SPX) Dec 14, 2004Researchers at UT Southwestern Medical Center at Dallas have used canine DNA to identify a genetic mutation mechanism they believe is responsible for rapid evolutionary changes in the physical appearance of many species. Exploring Ocean Life And Color On The Internet 
Greeenbelt MD (SPX) Dec 15, 2004A new NASA Internet tool called "Giovanni" allows high school and college students and researchers to access and analyze satellite-derived ocean color data. Ocean color data provides students with information about ocean biology by looking at phytoplankton through changes in the color of the ocean surface. A Deep Sea Hydrocarbon Factory 
Minneapolis MN (SPX) Dec 13, 2004A team of University of Minnesota scientists has discovered how iron- and chromium-rich rocks can generate natural gas (methane) and related hydrocarbons when reacted with superheated fluids circulating deep beneath the floor of the Atlantic Ocean. Putting Earth In Rehab 
University Park PA (SPX) Dec 10, 2004The length of time necessary to recover from a mass extinction may seem like a problem from the past, but a team of Penn State researchers is investigating recovery from the second largest extinction in Earth's history at the end of the Ordovician 443 million years ago and sees some parallels to today's Earth. Deep Tremors Under San Andreas Fault Could Portend Earthquakes 
Berkeley CA (SPX) Dec 10, 2004University of California, Berkeley, seismologists have discovered mysterious tremors deep under the San Andreas Fault that may portend future earthquakes. What Have Scientists Learned Since Mount St. Helens Erupted 
Portland OR (SPX) Dec 09, 2004When Mount St. Helen's blew its top in 1980, Charlie Crisafulli was 22 years old and just beginning his career as a research ecologist. One of his first assignments: travel to Mount St. Helens 2 months after the historic eruption and study the aftermath. |
Speed Of Tectonic Plate Activity Controls Geologic Processes
New York NY (SPX) Dec 09, 2004A new study has revealed a mechanism that counters established thinking on how the rate at which tectonic plates separate along mid-ocean ridges controls processes such as heat transfer in geologic materials, energy circulation and even biological production. Ocean Tides Once Spread Massive Icebergs: Study 
Toronto ON (SPX) Dec 09, 2004Labrador Sea ocean tides dislodged huge Arctic icebergs thousands of years ago, carrying gigantic ice-rafted debris across the ocean and contributing to the ice age's deep freeze, say an international team of university researchers. Blair Seeks To Secure Bush Backing For New Climate Treaty: Times 
London, UK (AFP) Dec 09, 2004British Prime Minister Tony Blair is seeking to secure US President George W. Bushs backing for a new international treaty that would end US isolation in the fight against global warming, a newspaper said Thursday. Calling The Roll On The Alaska National Wildlife Refuge 
Boulder CO (UPI) Dec 01, 2004The new makeup of the U.S. Senate is giving Republicans their best opportunity since the Bush administration took office to open up the Alaska National Wildlife Refuge to drilling for oil and natural gas. Spotlight On Space Debris 
Darmstadt, Germany (ESA) Dec 06, 2004At closing speeds reaching 50 thousand km per hour, even the smallest bits of space debris can cause serious harm to spacecraft; larger ones cause catastrophe. Near-Earth missions, like the International Space Station, now carry ever-more sophisticated shielding. Argo Robotic Instrument Network Now Covers Most Of The Globe 
San Diego CA (SPX) Dec 02, 2004Scientists have crossed an important threshold in an international effort to deploy a global network of robotic instruments to monitor and investigate important changes in the world's oceans. NASA Study Finds Glacier Doing Double Time 
WASHINGTON DC (SPX) Dec 02, 2004A NASA-funded study found the world's fastest glacier, Greenland's Jakobshavn Isbrae, doubled its speed of ice flow between 1997 and 2003. The study provides key evidence of newly discovered relationships between ice sheets, sea level rise and climate warming. The study appears in this week's issue of the journal Nature. |
