Deep magmatic plumbing of mid-ocean ridges revealed
Some of the highest quality images ever taken of the Earth's lower crust reveal that the upper and lower crust form in two distinctly different ways. view more (2005-08-25)
Scientists develop model to map continental margins
Scientists at the University of Liverpool have developed a new exploration method to assist the oil and gas industry in identifying more precisely where the oceans and continents meet. view more (2008-09-09)
X-rays use diamonds as a window to the center of the Earth
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks? view more (2008-08-13)
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)
Discovered: Cooling system under the sea floor
EMBARGO: February 5th, 8 pm The scientific, technical and logistic support of the geo scientists from Bremen, Prof. V. Spiess, Dr. L. Zühlsdorff and Prof. H. Villinger was instrumental in the discovery of a 50 km long cooling system by US-scientists under the sea floor off the north-west American coast. Its cornerstones are rocky outcrops... view more...

Scientists Find Bacteria Thriving on a Feast of Seafloor Rock
On the deep ocean floor, microbial life is feeding on fresh volcanic rock and flourishing with greater abundance than even the most optimistic scientists thought possible. According to a study published May 28 in the journal Nature, scientists have found bacteria growing on oceanic crust in concentrations that are thousands- to ten-thousand times... view more...

Scientists penetrate fossil magma chamber beneath intact ocean crust - achieving scientific 'first'
Approximately 800 km west of Costa Rica an international team of scientists aboard the research drilling ship JOIDES Resolution has¡-for the first time-recovered black rocks known as gabbros from intact ocean crust. view more (2006-04-21)
Investigating the deepest layers of the Earth's crust
The deep layers of the Earth's crust and the upper part of its mantle have been the target for investigation by a number of research groups at the EHU/UPV. This deep zone, and the processes that have taken place there in the past, can be investigated by means of studying those rocks which today are lying on the surface but which in past geological... view more...

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)
New activity on old fault lines: French earthquake no surprise
The relatively powerful earthquake that hit eastern France last Saturday confirms the findings of the postgraduate research currently being conducted by Gideon Lopes Cardozo at the Université Louis Pasteur in Strasbourg and the Faculty of Earth and Life Sciences at the VU Amsterdam. Lopes Cardozo is investigating the causes of earthquakes... view more... (2003-02-27)
Bacteria 'Feed' on Earth's Ocean-Bottom Crust
Seafloor bacteria on ocean-bottom rocks are more abundant and diverse than previously thought, appearing to "feed" on the planet's oceanic crust, according to results of a study reported in this week's issue of the journal Nature. view more (2008-05-29)
Scripps/UCSD geophysicist among international team finding evidence of first plate tectonics
Identification of the oldest preserved pieces of Earth's crust in southern Greenland has provided evidence of active plate tectonics as early as 3.8 billion years ago, according to a report by an international team of geoscientists in the March 23 edition of Science magazine. view more (2007-03-23)
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)
Declining sharks
The transformation of terrestrial and coastal ecosystems by humans is well known, but only recently have the impacts of anthropogenic forces in the open ocean been recognized. In particular, intense exploitation by industrial fisheries is rapidly changing oceanic ecosystems by drastically reducing populations of many marine species. For most... view more... (2004-02-05)
Mysteries of the Atlantic
Cardiff University scientists will shortly set sail (March 5) to investigate a startling discovery in the depths of the Atlantic. view more (2007-03-02)
McGill researchers find oldest rocks on Earth
McGill University researchers have discovered the oldest rocks on Earth - a discovery which sheds more light on our planet's mysterious beginnings. view more (2008-09-26)
Exploring Mars ... from Grenoble
A neutron diffraction experiment carried out recently at the Institut Laue-Langevin in Grenoble by the physicists Bachir Ouladdiaf (ILL), Gérard Fillion and Rafik Ballou (Laboratoire Lois Néel, CNRS, GRENOBLE), in partnership with the geophysicists Pierre Rochette (CNRS and Université d'Aix-Marseille) and Lon Hood (University... view more...

Key component of Earth's crust formed from moving molten rock
Earth scientists are in the business of backing into history -- extrapolating what happened millions of years ago based on what they can observe now. Using this method, a team of Cornell researchers has created a mathematical computer model of the formation of granulite, a fine-grained metamorphic rock, in the Earth's crust. view more (2008-03-06)
Study reconciles long-standing contradiction of deep-earth dynamics
Researchers at Columbia University's Lamont-Doherty Earth Observatory recently resolved a long-standing contradiction about the workings of the deep Earth. view more (2005-08-25)
Evidence from Hawaiian volcanoes shows that Earth recycles its crust
A geologist at Rutgers, The State University of New Jersey, has come up with evidence our planet practices recycling on a grand scale. view more (2006-11-30)
