San Francisco - Nov 27, 2003Two University of California, Berkeley, geophysicists have proposed an explanation for the unpredictable nature of volcanic eruptions, why volcanoes sometimes ooze lava, but at other times explode in showers of ash and pumice. Geologists Discover New Class Of Spreading Ridge On Sea Bottom 
WASHINGTON - Nov 27, 2003Scientists have discovered a new "ultra-slow" class of ocean ridge involved in seafloor spreading. Investigations in the remote regions of the planet--in the far south Atlantic and Indian Oceans and the sea floor beneath the Arctic icecap--found that for large regions there, the sea floor splits apart by pulling up solid rock from deep within the earth. These rocks, known as peridotites (after the gemstone peridot) come from the deep layer of the earth known as the mantle. |

Orbital Awarded GOES-R Study Contract
Dulles - Nov 25, 2003Orbital Sciences Corporation said Monday that it has been awarded a $2 million contract by the National Oceanic and Atmospheric Administration (NOAA) to conduct studies of potential space and ground system architectures for the next generation of the Geostationary Operational Environmental Satellite (GOES) system known as GOES-R. Old Japanese Tsunami Data Points To Massive Quakes In North America 
Reston - Nov 25, 2003Guided by Japanese writings from an era of shoguns, an international team of scientists today reported new evidence that an earthquake of magnitude 9 struck the northwestern United States and southwestern Canada three centuries ago. The findings are likely to affect the region's precautions against future earthquakes and tsunamis. Sarsat Caps Busy Week With Life-Saving Rescue Operations 
Washington - Nov 25, 2003On land and in the sea satellites helped save lives the past week. In one incident, two passengers onboard a sailing vessel from Harpswell, Maine, headed for the Caribbean Island of Antigua, made it only as far as Nantucket, Mass., because of rough sea conditions spawned by violent weather.

Stanford - Nov 25, 2003Despite tremendous technological advances in earthquake seismology, many fundamental mysteries remain. The critical question of whether earthquakes will ever be predictable continues to plague seismologists � in part because there is no way to directly observe what goes on miles below the surface where earthquakes occur. Greatest Extinction Probably Caused By Meteorite Or Comet Impact 
Rochester - Nov 24, 2003Long before the dinosaurs ever lived, the planet experienced a mass extinction so severe it killed 90 percent of life on Earth, and researchers at the University of Rochester think they've identified the unlikely culprit. Tiny Automated Sensors Could Help Map Disaster Areas 
Ithaca - Nov 20, 2003A train has derailed at the edge of a city, spreading toxic chemicals and fumes over a wide area. Before rescue and decontamination workers can enter the danger zone, they need more information: How widespread is the contamination? Where are the hotspots? Where and how are toxic gases moving? NOAA Reports Methane Levels Stablizing 
WASHINGTON - Nov 19, 2003One of the atmosphere's most potent greenhouse gases, methane, may now have leveled off, according to a study by NOAA researchers and National Institute for Space Research in the Netherlands. Scientists aren't sure yet if this "leveling off" is just a temporary pause in two centuries of increase or a new state of equilibrium. |
A Mostly Quiet Pacific 
Pasadena - Nov 19, 2003 Some climate forecast models indicate there is an above average chance that there could be a weak to borderline El Ni�o by the end of November 2003. However, the trade winds, blowing from east to west across the equatorial Pacific Ocean, remain strong. Uncovering Mysteries Beneath The Earth's Surface 
Boston - Nov 19, 2003Back in the old days, when doctors looked for tumors, exploratory surgery was the only option. Today they use CAT scans, x-rays, ultrasound, and other non-intrusive methods for checking out what lies beneath the skin's surface. But how do we determine what is beneath the Earth's surface? Invasive surgery on the Earth is just as dated as doctors' old methods of finding tumors, if you ask Eric Miller, associate professor of electrical and computer engineering at Northeastern University. NOAA Awards Harris Study For GOES-R Ground Segment
Melbourne - Nov 18, 2003Harris Corporation has been awarded a one- year study contract by the National Oceanic and Atmospheric Administration (NOAA) for ground segment work supporting the advanced Geostationary Operational Environmental Satellite-R (GOES-R) program. Scheduled to launch in 2012, GOES-R will feature highly advanced sensor technology and will provide much higher resolution and data frequency than the current GOES spacecraft family. Russia Conducts Widespread Atmospheric Temperature Study
St. Petersburg - Nov 18, 2003A group of researchers guided by Academician Kondratyev has analyzed the archives of temperatures in the Northern Arctic area since 1959 through 2000. Having done this analysis, the researchers stated that constant thermal energy redistribution took place in high latitudes, therefore the state of atmosphere in general had not changed. Iceberg's End Caught By Envisat 
Paris (ESA) Nov 11, 2003ESA's Envisat satellite was witness to the dramatic last days of what was once the world's largest iceberg, as a violent Antarctic storm cracked a 160-km-long floe in two. Arctic And Antarctic Sea Ice Marching To Different Drivers 
Greenbelt - Nov 11, 2003A 30-year satellite record of sea ice in the two polar regions reveals that while the Northern Hemisphere Arctic ice has melted, Southern Hemisphere Antarctic ice has actually increased in more recent years. However, due to dramatic losses of Antarctic sea ice between 1973 and 1977, sea ice in both hemispheres has shrunk on average when examined over the 30-year time frame. Yucca Mountain Site Must Make Use Of Geological Safety Net 
Bloomington - Nov 11, 2003A proposed federal repository near Yucca Mountain, Nev., for the long-term storage of 70,000 metric tons of high-level radioactive waste must take advantage of the mountain's natural geological properties, according to a new study by scientists at Indiana University Bloomington and Los Alamos National Laboratory. |
