STARKVILLE, Miss., Aug. 26, 2014 /PRNewswire-USNewswire/ -- New questions about geology, oceanography and seafloor ecosystems are being raised because of research by a Mississippi State University geologist. Lead author Adam Skarke, assistant professor of geosciences at MSU, worked with researchers from the U.S. Geological Survey (USGS) and other institutions on a scientific team that discovered methane seeps in unlikely places along the seafloor on the northern part of the U.S....

New View Of Area Where Malaysia Airlines Flight 370 Might Lie
2014-05-27 03:26:48

American Geophysical Union A new illustration of the seafloor, created by two of the world’s leading ocean floor mapping experts that details underwater terrain where the missing Malaysia Airlines flight might be located, could shed additional light on what type of underwater vehicles might be used to find the missing airplane and where any debris from the crash might lie. The seafloor topography map illustrates jagged plateaus, ridges and other underwater features of a large area...

Int'l Researchers Find Deep Ocean Waters Littered With Human Trash
2014-05-01 09:01:44

Lawrence LeBlond for redOrbit.com - Your Universe Online A study released last year confirmed just how far human trash sinks in the ocean, finding detritus as much as 13,000 feet deep off the coast of California. Now, a new study published in the journal PLOS ONE has revealed that even the deepest ocean depths is home to bottles, plastic bags, fishing nets and other types of human litter. The new study, led by Cristopher Pham of the University of the Azores, focused on the Mediterranean...

Hydrothermal Vent Supply Routes Explained With Computer Simulations
2014-04-25 03:00:09

GEOMAR Helmholtz Centre for Ocean Research Kiel GEOMAR scientists demonstrate in "Nature" the supply routes of black smokers Hydrothermal vents in the deep sea, the so-called "black smokers", are fascinating geological formations. They are home to unique ecosystems, but are also potential suppliers of raw materials for the future. They are driven by volcanic "power plants" in the seafloor and release amounts of energy that could meet the needs of a small town. But how exactly do they...

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....
