Geoscientist Leads International Drilling Mission To Lower Crust Of Pacific
2013-12-04 11:33:49

University of Houston A University of Houston (UH) geoscientist and his colleagues are revealing new discoveries about the Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean. Co-chief scientists Jonathan Snow from UH and Kathryn Gillis from University of Victoria in Canada led a team of 30 researchers from around the world on the $10 million expedition, finding a few surprises upon...

Scientists Document Scavenging For Oxygen In Seawater Circulating Through Deep Oceanic Crust
2013-09-27 11:16:26

Bigelow Laboratory for Ocean Sciences Although long thought to be devoid of life, the bottom of the deep ocean is now known to harbor entire ecosystems teeming with microbes. Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere" beneath the sea floor is able to survive and thrive. The new research findings were published in the journal Nature...

Japan Earthquake Produced Largest Slip Ever Recorded
2013-02-08 05:47:23

Alan McStravick for redOrbit.com - Your Universe Online As we are quickly approaching the two-year anniversary of the Tohoku-Oki earthquake that prompted the devastating Honshu tsunami, we learned this week about a rapid-response drilling operation at the site of the earthquake. The March 2011 earthquake, a magnitude 9.0 temblor, was responsible for producing a 164-foot-tall slip along the fault. This is the single largest slip ever recorded in an earthquake. Needless to say, such a...

Volcanoes Erupt When Ice Melts

Michael Harper for redOrbit.com — Your Universe Online For every action, there is an equal and opposite reaction. This fact holds true in a myriad of situations from physics to our global climate. Numerous studies have shown even the smallest change in an ecosystem can affect seemingly unrelated aspects to the same area. Today, German researchers along with researchers from Harvard University in Cambridge, Massachusetts have published a study detailing how global ice affects...

Journey To The Center Of The Earth Planned
2012-10-03 10:54:54

Michael Harper for redOrbit.com — Your Universe Online The Mars Curiosity rover is sending data and pictures to Earth from Mars every day with only a 14 minute delay, a monumental feat of human accomplishment. Yet, for all our research into the stars, there remains a great deal of discovery to be had here on Earth, particularly below the surface. Now, a global team of drillers, geologists and other scientists and researchers plan to spend $1 billion to go the other way, deep into...

New World Drilling-Depth Record Of Scientific Ocean Drilling Set By Chikyu
2012-09-06 09:27:35

Scientific deep sea drilling vessel Chikyu sets a world new record by drilling down and obtains rock samples from deeper than 2,111 meters below the seafloor off Shimokita Peninsula of Japan in the northwest Pacific Ocean. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC), the implementing organization for scientific expedition aboard the Chikyu, announced this achievement on 6th September, 2012. Chikyu made this achievement during the Deep Coalbed Biosphere expedition,...

Past Climate Change Linked With Ancient Alteration of Seawater Chemistry
2012-07-20 15:41:27

Dissolution or creation of huge gypsum deposits changed sulfate content of the oceans Scientists have discovered a potential cause of Earth's "icehouse climate" cooling trend of the past 45 million years. It has everything to do with the chemistry of the world's oceans. "Seawater chemistry is characterized by long phases of stability, which are interrupted by short intervals of rapid change," says geoscientist Ulrich Wortmann of the University of Toronto, lead author of a paper...

Ice Sheet Collapse And Sea-level Rise At The Bølling Warming 14,600 Years Ago
2012-04-06 04:23:00

International scientists have shown that a dramatic sea-level rise occurred at the onset of the first warm period of the last deglaciation, known as the Bølling warming, approximately 14,600 years ago. This event, referred to as Melt-Water Pulse 1A (MWP-1A), corresponds to a rapid collapse of massive ice sheets 14,600 years ago and resulted in global sea-level rise of ~14 m. These findings are published in the 29 March 2012 issue of the journal Nature (Volume 483, Issue 7391)....

Image 1 - Scientists Examine Peculiar Underwater Mountain
2012-03-27 10:53:47

Scientists have recently finalized an expedition in an effort to learn more about an undersea mountain they say may have formed in a very different way than the rest of the seafloor. Aboard the JOIDES (Joint Oceanographic Institutions for Deep Earth Sampling) research ship, these scientists studied the formations and makeup of Atlantis Massif. This undersea mountain has been found to be made up of rocks typically found much deeper in the oceans crust. Other volcanic seamounts are usually...
