Examining gas outlets off the coast of Spitsbergen with the submersible JAGO West of Spitsbergen methane gas is effervescing out of the seabed. Is this an indication that methane hydrates in the seabed are dissolving due to rising temperatures? And what would the effects be? An expedition with the German research vessel MARIA S. MERIAN and the submersible JAGO lead by GEOMAR | Helmholtz Centre for Ocean Research Kiel hopes to help answer these questions. The expedition begins today in...

Ocean Found To Be Surprising Source Of Arctic Methane
2012-04-23 03:49:05

The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study by Eric Kort of NASA's Jet Propulsion Laboratory, Pasadena, Calif., has uncovered a surprising and potentially important new source of Arctic methane:...

Computer simulations revealing how methane and hydrogen pack into gas hydrates could enlighten alternative fuel production and carbon dioxide storage industries For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis of the ice and gas compound, known as a gas hydrate, reveals key details of its structure. The results show that hydrates can hold hydrogen at an optimal capacity of 5...

Rice researchers show ocean could have contained enough methane to cause drastic climate change The release of massive amounts of carbon from methane hydrate frozen under the seafloor 56 million years ago has been linked to the greatest change in global climate since a dinosaur-killing asteroid presumably hit Earth 9 million years earlier. New calculations by researchers at Rice University show that this long-controversial scenario is quite possible. Nobody knows for sure what started...

A shipboard expedition off Norway, to determine how methane escapes from beneath the Arctic seabed, has discovered widespread pockets of the gas and numerous channels that allow it to reach the seafloor. Methane is a powerful "greenhouse" gas and the research, carried out over the past week aboard the Royal Research Ship James Clark Ross, will improve understanding of its origins in this area, its routes to the sea floor and how the amount of gas escaping might increase as the ocean warms....

New study goes deeper in proving simple technique to pinpoint valuable energy source Their critics weren't convinced the first time, but Rice University researchers didn't give up on the "ice that burns." A paper by a Rice team expands upon previous research to locate and quantify the amount of methane hydrates -- a potentially vast source of energy -- that may be trapped under the seabed by analyzing shallow core samples. The paper published this week by the Journal of Geophysical...

Image 1 - Study Casts Doubts On Natural Gas's Impact On Global Warming

  Despite the reduced amount of carbon dioxide given off by the burning of natural gas, increasing use of it and decreasing our reliance on coal would do little to slow down global climate change, claims a new study set for publication in the journal Climatic Change Letters. The research, led by Tom Wigley, a senior research associate at the National Center for Atmospheric Research (NCAR), "underscores...the complex and sometimes conflicting ways in which fossil fuel burning...

ORLANDO, Fla., Aug. 15, 2011 /PRNewswire/ -- GDT TEK, Inc. (OTC: GDTK) today announced that its 50% owned subsidiary Steriwave-GDT Tek has filed a patent application for a system that safely removes and captures methane hydrates from undersea reserves. The main design of the Steriwave-GDT Tek subsea open pit drilling/extraction concept is to provide maximized safety versus environmental issues. Methane hydrates, which form at low temperature and high pressure, are found in sea-floor...

Researchers have pinpointed the timing of the start of an ancient global warming episode known as the Paleocene-Eocene thermal maximum (PETM). The early part of the Cenozoic era witnessed a series of transit global warming events called hyperthermals.  The most severe of these was the PETM at the Paleocene-Eocene boundary, which took place around 56 million years ago. Over a 20,000-year period, ocean temperatures rose globally by about 41 degrees Fahrenheit.  The team said one...

Marine scientists cast doubt on Thursday about an earlier study that found bacteria had consumed nearly all of the methane that leaked into the Gulf of Mexico amid last year's BP oil spill. Calling the widely-publicized study's findings "ambiguous" and "unconvincing", they said the methods used were flawed and warranted further review. "We find the complete methane oxidation hypothesis unconvincing," wrote Samantha Joye and colleagues from 12 other institutions in a technical comment...
