Studies of naturally carbonated mineral water have given scientists insight on how to locate hot water springs -- potential sources of sustainable geothermal energy.
Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union. The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has long puzzled scientists -- why Arctic and sub-Arctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.
An international team of scientists digging in a sea cave in Indonesia has discovered the world's most pristine record of tsunamis, a 5,000-year-old sedimentary snapshot that reveals for the first time how little is known about when earthquakes trigger massive waves.
The presence of carbonates in the Earth's mantle is known from diamond inclusions, but how carbon is transported there remains a mystery. An international team has shed light on this mystery thanks to high-pressure experiments carried out at the European Synchrotron. The scientists revealed two new iron carbonate compounds and found that self-oxidation-reduction reactions could preserve carbonates in the mantle, hence becoming a potential carbon carrier down to the top of the Earth's core.
A one trillion tonne iceberg -- one of the biggest ever recorded -- has calved away from the Larsen C Ice Shelf in Antarctica, after a rift in the ice, monitored by the Swansea University-led MIDAS project, finally completed its path through the ice.
Physicists from the University of Würzburg have discovered surprising properties of nickel. They could help unravel some mysteries about Earth's magnetic field.
University of Alaska Fairbanks researchers have discovered that volcanoes have a unique way of dealing with pressure -- through crystals. According to a new study published in the Journal of Geology, if enough crystals can develop in rising magma, then a network of microscopic crystals can lessen the internal pressure of rising magma and reduce the explosiveness of eruptions.
Scientists have identified patterns in the Earth's magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not previously known.
Reporting this week in the journal Nature, an international team of researchers led by British Antarctic Survey explains that wind-driven incursions of warm water forced the retreat of glaciers in West Antarctica during the past 11,000 years. These new results enable researchers to better understand how environmental change may impact future sea-level rise from this climate-sensitive region.
Climate change could turn one of Africa's driest regions into a very wet one by suddenly switching on a Monsoon circulation. For the first time, scientists find evidence in computer simulations for a possible abrupt change to heavy seasonal rainfall in the Sahel, a region that so far has been characterized by extreme dryness.
