A research team at Penn State discovered that consortia of bacteria and archaeobacteria consume up to 80% of marine methane, a potent greenhouse gas. The findings indicate that these microorganisms play a crucial role in regulating the Earth's climate.
A team of scientists will explore the Gulf of Mexico's extreme environments, including brine pools and cold seeps, to better understand their role in global warming. They will collect samples and study microbial processes to gain insights into methane oxidation and nutrient concentrations.
Researchers investigate the link between ocean changes and hydrate stability using sediment cores and chemical markers. They aim to identify past environments with gas hydrates and explore how they affected the atmosphere in the past.
Geochemist Jeffrey Severinghaus will investigate the stability of past and future climates using a new technology for extracting air samples from ancient ice cores. His research aims to decipher how methane hydrates contribute to the atmospheric methane budget and potentially trigger catastrophic climate changes.
Researchers have found a way to convert oil to methane gas using specialized microorganisms living beneath the earth's surface. This breakthrough could lead to safer oil exploration and more efficient extraction methods.
Researchers found that using methane with a palladium-based catalyst can remove nearly 100% of nitric oxide from stack gases, a process considered more environmentally friendly and cost-effective than current methods. However, the sulfur dioxide present in some emissions interferes with the reaction.
A team of scientists, including INEEL microbiologist Mark Delwiche, drilled into the ocean floor off Japan in search of methane-producing microorganisms. The goal is to understand how fast these microorganisms produce methane and potentially unlock a new renewable energy source.
Researchers discovered strong evidence of a 55.5 million-year-old global warming event linked to a massive methane release. The 'latest Paleocene thermal maximum' led to the extinction or disappearance of deep-sea species and changed ecosystems. Further research is needed to understand this phenomenon.
A recent study by University of Illinois researchers suggests that including methane in emission-reduction strategies can significantly lower overall costs. The study found that methane can offset carbon dioxide reductions and reduce U.S. abatement costs by more than 25 percent compared to strategies involving carbon dioxide alone.
Researchers discover microbes convert saturated hydrocarbon hexadecane to methane and carbon dioxide, leading to potential methane formation in old sediments. This process, known as microbial hydrocarbon 'cracking,' sheds light on slow yet globally relevant microbial processes in deep subsurface environments.
Researchers at Michigan Tech have developed a new sun-driven process to create liquid methanol from methane, a plentiful but often wasted gas. The process uses near-UV light and a titanium-based catalyst, promising to make natural gas more commercially viable and reduce emissions.
A University of Iowa researcher has discovered that termite bacteria consume hydrogen, converting it into acetate, an excellent food source for termites and cows. This finding could lead to improvements in cattle nutrition and decreases in their methane emissions, a major contributor to global warming.
A cost-effective method to eliminate methane emissions from coal mines has been developed by Natural Resources Canada. The system uses a secret catalyst to oxidize methane to water and CO2, generating heat and electricity in the process.
Researchers have discovered dense colonies of flat, pinkish worms living in methane ice mounds on the Gulf of Mexico sea floor. The worms are thought to be grazing off chemosynthetic bacteria, potentially influencing gas deposit formation and energy harvesting.
Researchers find massive methane deposits in Blake Ridge area, equivalent to 35 billion tons, and estimate 7% of global carbon stored. The discovery suggests a significant role in past climate change and potential for future energy source.
A significant reservoir of methane and hydrocarbons has been discovered in rock beneath the ocean floor, potentially supporting a wide range of microorganisms. The findings, presented by University of Washington oceanographer Deborah Kelley, suggest that these microbes may thrive on chemicals toxic to other life forms.
Researchers analyzed ancient methane levels in ice cores, revealing patterns of climate change over the past 110,000 years. The study confirms high methane levels during warm periods and suggests a link between global warming and changes in terrestrial climate.
