Warmer means windier on world's biggest lake
Rising water temperatures are kicking up more powerful winds on Lake Superior, with consequences for currents, biological cycles, pollution and more on the world's largest lake and its smaller brethren. view more (2009-11-16)
A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. view more (2009-11-13)
Deep creep means milder, more frequent earthquakes along Southern California's San Jacinto fault
With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience. view more (2009-11-09)
Study uses satellite imagery to identify active magma systems in East Africa's Rift Valley
A team from the University of Miami, University of El Paso and University of Rochester have employed Interferometric Synthetic Aperture Radar (InSAR) images compiled over a decade to study volcanic activity in the African Rift. The study, published in the November issue of Geology, studies the section of the rift in Kenya. view more (2009-11-05)
Study gives clearer picture of how land-use changes affect U.S. climate
Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change. view more (2009-11-04)
Iron controls patterns of nitrogen fixation in the Atlantic
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. view more (2009-11-03)
Geologists point to outer space as source of the Earth's mineral riches
According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin. view more (2009-10-19)
Banded rocks reveal early Earth conditions, changes
The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago. view more (2009-10-12)
NASA satellite reveals a depressed and disorganized Henri
Depression happens to everyone, even tropical storms, and Henri is now tropically depressed. NASA satellite imagery has confirmed he's weakened to a tropical depression and he is further expected to degenerate into a remnant low pressure area. view more (2009-10-09)
Storm Killers: LSU's Earth Scan Lab Tracks Cold Water Upwellings in Gulf
Complex interactions between the ocean and overlying atmosphere cause hurricanes to form, and also have a tremendous amount of influence on the path, intensity and duration of a hurricane or tropical weather event. view more (2009-09-29)
'Rosetta Stone' of supervolcanoes discovered in Italian Alps
Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale - and possibly trigger climatic and environmental effects at a global scale. view more (2009-09-21)
First complete image created of Himalayan fault, subduction zone
An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved. view more (2009-09-14)
Time to lift the geoengineering taboo
Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering - deliberate interventions in the climate system to counteract man-made global warming - more seriously. view more (2009-09-01)
Slowly slip-sliding faults don't cause earthquakes
Some slow-moving faults may help protect some regions of Italy and other parts of the world against destructive earthquakes, suggests new research from The University of Arizona in Tucson. view more (2009-08-28)
Listening to rocks helps researchers better understand earthquakes
When Apollo punished King Midas by giving him donkey ears, only the king and his barber knew. Unable to keep a secret, the barber dug a hole, whispered into it, "King Midas has donkey ears," and filled the hole. But plants sprouted from the hole, and with each passing breeze, shared the king's secret. view more (2009-08-18)
Surface features on Titan form like Earth's, but with a frigid twist
"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August. view more (2009-08-07)
IODP introduces technology to support deepwater crustal drilling
The Integrated Ocean Drilling Program (IODP), in collaboration with industry partner AGR Drilling Services, has engineered an ultra-deepwater drilling technology for use by IODP drilling vessels in scientific research. view more (2009-08-04)
Hydrocarbons in the deep Earth?
The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. view more (2009-07-27)
FSU scientists unveil new seasonal hurricane forecasting model
Scientists at The Florida State University's Center for Ocean-Atmospheric Prediction Studies (COAPS) have developed a new computer model that they hope will predict with unprecedented accuracy how many hurricanes will occur in a given season. view more (2009-07-16)
Natural deep earth pump fuels earthquakes and ore
For the first time scientists have discovered the presence of a natural deep earth pump that is a crucial element in the formation of ore deposits and earthquakes. view more (2009-06-18)
