Latest Oceanic trench Stories

Peter Suciu for Redorbit.com Director James Cameron certainly knows a thing or two about working underwater. For his 1997 film Titanic, which won an Academy Award for best picture, he actually headed to the watery grave of the infamous ocean liner. The ship, which sank nearly 100 years ago on its maiden voyage, has become a thing of legend, and now Cameron looks to go even deeper and explore the Mariana Trench’s Challenger Deep. This past Wednesday the self-proclaimed “King of the...

An ocean mapping expedition has shed new light on deepest place on Earth, the 2,500-kilometer long Mariana Trench in the western Pacific Ocean near Guam. Using a multibeam echo sounder, state-of-the-art equipment for mapping the ocean floor, scientists from the University of New Hampshire Center for Coastal and Ocean Mapping/Joint Hydrographic Center found four “bridges” spanning the trench and measured its deepest point with greater precision than ever before. Research professor James...

Science have probed the climate secrets of the Marianas Trench in the western Pacific Ocean.The international team used a submersible, designed to withstand immense pressures, to study the bottom of the deepest part of the ocean. The scientist early results reveal that ocean trenches are acting as carbon sinks. This suggests that they play a larger role in regulating the Earth's chemistry and climate than what was previously thought. Although explorers Jacques Piccard and Don Walsh reached...

Researchers at Monash University and Scripps Institution of Oceanography identify movements of plate and plate boundaries; could substantially improve models of tectonic motionA team of researchers including Scripps Institution of Oceanography, UC San Diego geophysicist Dave Stegman has developed a new theory to explain the global motions of tectonic plates on the earth's surface.The new theory extends the theory of plate tectonics - a kinematic description of plate motion without reference...

Deep sea teeming with species that have never known sunlightCensus of Marine Life scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight - creatures that somehow manage a living in a frigid black world down to 5,000 meters (~3 miles) below the ocean waves.Revealed via deep-towed cameras, sonar and other vanguard technologies, animals known to thrive in an eternal watery darkness now number 17,650, a diverse...

WASHINGTON (AP) -- Tiny single-celled organisms, many of them previously unknown, have been discovered beneath nearly seven miles of water in the deepest part of the ocean. A sample of sediment collected from the Challenger Deep southwest of Guam in the Pacific Ocean Islands yielded several hundred foraminifera, a type of plankton that is usually abundant near the ocean surface. "On the species level, all the species we found from the Challenger Deep are quite new," researcher...
