Water Crisis Could Be Averted By Newly-Discovered Undersea Freshwater Reserves
2013-12-09 05:16:17

[ Watch the Video: Freshwater Reserves Found Underneath The Sea ] redOrbit Staff & Wire Reports - Your Universe Online A team of Australian researchers have reportedly located massive freshwater reserves trapped beneath the ocean floor – a discovery that could help delay or prevent a burgeoning global water crisis, according to research published Thursday in the journal Nature. Flinders University professor Vincent Post, a hydrogeologist specializing in coastal groundwater...

Feast And Famine For Animals Living On The Abyssal Plain
2013-11-12 11:57:06

[ Watch The Video: Feast and Famine on the Abyssal Plain ] Monterey Bay Aquarium Research Institute Animals living on the abyssal plains, miles below the ocean surface, don’t usually get much to eat. Their main source of food is ”marine snow”—a slow drift of mucus, fecal pellets, and body parts—that sinks down from the surface waters. However, researchers have long been puzzled by the fact that, over the long term, the steady fall of marine snow cannot account for all the...

Unexpected Plume Challenges Iron Estimates
2013-08-20 08:47:27

April Flowers for redOrbit.com - Your Universe Online A vast plume of iron and other micronutrients more than 620 miles long has been discovered billowing from hydrothermal vents in the South Atlantic Ocean. Teams of scientists from Woods Hole Oceanographic Institute (WHOI) and the University of Liverpool, UK say their findings, published in an upcoming issue of Nature Geoscience, call into question past estimates of iron abundances and may challenge researchers’ previous assumptions...

USGS Maps California Seafloor In Unprecedented Detail
2013-08-12 14:59:57

Peter Suciu for redOrbit.com - Your Universe Online While California offers an impressive shoreline, new research has been able to look beyond just the surface and has been used to reveal the hidden seafloor in unprecedented detail. Three new products in an ongoing series were released last week by the US Geological Survey (USGS), and include a map set for the area offshore of Carpinteria, a catalog of data layers for geographic information systems and even a collection of videos and...

Underwater Volcano System Proposed As National Park For Norway
2013-08-05 05:11:28

Susan Bowen for redOrbit.com - Your Universe Online Off the coast of Norway, on the floor of the Arctic Ocean, lies a largely unexplored world of undersea volcanoes. This system, with the fanciful name of Loki's Castle, contains rich metal deposits and unique wildlife. This field of five active hydrothermal vents was discovered in 2008. A team from the University of Bergen (UiB), led by Professor Rolf Birger Pedersen, continues to make discoveries at the site, which is thought to be the...

Absence Of Modern Day Greenhouse Gas Emissions Revealed By NRL Geochemistry Survey At Chatham Rise
2013-05-29 13:48:18

U.S. Naval Research Laboratory Geochemistry analysis conducted by the U.S. Naval Research Laboratory of fossil sediment injection structures off the New Zealand coast in February and March reveal no presence of modern day expulsions of methane gas, a potential contributor to global 'greenhouse effect' warming. The main focus of this most recent expedition was to investigate the geological origin of seafloor anomalies discovered during a 2007 marine-life survey on the Chatham Rise....

Deep Magma Imaged Beneath Pacific Seafloor Volcano
2013-03-28 04:51:18

redOrbit Staff & Wire Reports - Your Universe Online By using electromagnetic technology to map a large area of seafloor near Central America and the northern East Pacific Rise, researchers from the Scripps Institution of Oceanography report that they have a better idea of the origin of the erupted magma that eventually becomes new seafloor. Scientists have known for several decades that the seafloor is formed throughout the major ocean basins at the linear chains of volcanoes known...

Magma May Be Natural Lubricant For Moving Tectonic Plates
2013-03-21 11:09:11

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the University of California, San Diego´s (UCSD) Scripps Institution of Oceanography (SIO) have discovered a liquefied layer of molten rock in the planet´s mantle — a substance which could be acting as a lubricant of the sliding motions of the Earth´s tectonic plates. The magma layer was discovered at the Middle America trench offshore Nicaragua during a 2010 expedition aboard the US Navy-owned...

Deepest Hydrothermal Vent Discovered In Cayman Deep, Teeming With Life
2013-02-22 09:43:30

Lawrence LeBlond for redOrbit.com - Your Universe Online In 2010, scientists working for the National Oceanography Centre (NOC) and the University of Southampton made an astonishing discovery: the deepest and hottest known hydrothermal vents. These vents, which were found in an isolated trough in the Caribbean, have been named the Beebe Hydrothermal Vent Field (BHVF). With the discovery still fresh in their minds, a new team, led by the University of Southampton´s Dr. Jon Copley,...

Rare Cold Volcanic Vent Discovered In Antarctic Waters
2013-02-07 10:51:55

April Flowers for redOrbit.com - Your Universe Online Scientists at the National Oceanography Centre (NOC), Southampton have discovered the location of an underwater volcanic vent in the Southern Ocean. In a study published this week in the journal PLOS ONE, the researchers describe how this vent, marked by a low-lying plume of shimmering water, differs from "classic" hydrothermal vents. The research group used the NOC´s high-resolution deep-towed camera platform SHRIMP to image...
