Bent tectonics
More than 80 undersea volcanoes and a multitude of islands are dotted along the Hawaii-Emperor seamount chain like pearls on a necklace. A sharp bend in the middle is the only blemish. view more (2009-04-03)
Volcanoes helped slow ocean warming trend, researchers find
Ocean temperatures might have risen even higher during the last century if it weren't for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity. view more (2006-02-10)
Continents loss to oceans boosts staying power
New research suggests that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. view more (2008-04-02)
Megatsunamis @ the London `Catastrophes` conference
The modern world appears secure in its knowledge of hazards. However tsunamis today are smaller and less frequent than they were in prehistory. view more (2002-08-17)
Geologists discover signs of volcanoes blowing their tops in the deep ocean
A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. view more (2008-06-26)
Sand dunes tell tale of volcanic devastation
University of Leicester scientists have made a unique discovery at an Atlantic island popular with British holidaymakers. They have uncovered giant sand dunes on Tenerife that tell a tale of terrifying destruction in ancient times, when fiery clouds swept right across the island, leaving very little in their wake. Volcanic islands - volcanoes... view more... (2004-05-06)
Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature. view more (2006-05-11)
'Magma P.I.' unearths clues to how crust was sculpted
About a decade ago, Johns Hopkins University geologist Bruce Marsh challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes. view more (2007-12-04)
Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean. view more (2007-04-13)
Scientists measure the rate of ascent of volcanic magma
Plinian volcanic eruptions are notoriously destructive. These very powerful eruptions often occur after long periods of quiescence and are preceded by relatively short periods of seismic restiveness. view more (2009-10-09)
Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
Laser Image Aimed at Achieving 85 Percent Reduction in Costs
An innovative laser imaging technique, developed with funding from the Office of Naval Research (ONR), could cut more than 7,700 man hours from the manufacturing cycle of the VIRGINA-Class Submarine (VCS). view more (2009-07-31)
Researchers Find Substantial Amount of Mercury Entering the Ocean through Groundwater
Researchers from the Woods Hole Oceanographic Institution (WHOI) have found a new and substantial pathway for mercury pollution flowing into coastal waters. Marine chemists have detected much more dissolved mercury entering the ocean through groundwater than from atmospheric and river sources. view more (2007-03-22)
NASA mission explores world's deepest sinkhole
A NASA-funded expedition, including researchers from Carnegie Mellon University's Robotics Institute, will begin searching for the submerged bottom of Mexico's El Zacatón sinkhole with a robotic submarine the week of May 14. view more (2007-05-15)
Building blocks of life formed on Mars
Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists at the Carnegie Institution's Geophysical Laboratory have shown for the first time that building blocks of life formed on Mars early in its history. view more (2007-12-12)
Permanent deep-sea seismic sensors
A submarine seismic sensor was recently set in place at 2400 m depth, off Toulon. The instrument was attached to a neutrino telescope developed by the international scientific programme Antares. view more (2005-06-06)
Scientist Anticipates Major Eruption of Peru`s El Misti Volcano
Boulder, Colo.- Scientist Jean-Claude Thouret is worried about the one million people who live in the suburbs and city of Arequipa in southern Peru. The city`s center is only 17 km from the summit of the active El Misti volcano. Thouret and his colleagues report new findings on El Misti`s geology, past eruptions, and the reasons for probable... view more... (2001-12-10)
NOAA Locates U.S. Navy Ship Sunk in World War II Battle
A NOAA-led research mission has located and identified the final resting place of the YP-389, a U.S. Navy patrol boat sunk approximately 20 miles off the coast of Cape Hatteras, NC, by a German submarine during World War II. view more (2009-09-10)
Scientists discover Amazon river is 11 million years old
Researchers at the University of Liverpool have discovered that the Amazon river, and its transcontinental drainage, is around 11 million years old and took its present shape about 2.4 million years ago. view more (2009-07-29)
European satellites provide new insight into ozone-depleting chemical species
Using data from the MIPAS and GOME-2 satellite instruments, scientists have for the first time detected important bromine species in the atmosphere. view more (2009-02-26)
