Peatlands release more methane when disturbed by roads
Roads built through acidic wetlands may make greenhouse gas emissions from the wetlands spike by damming natural water flow, according to a new study in AGU’s Journal of Geophysical Research: Biogeosciences.

Study provides new clues to source of methane gas on Mars
A team of researchers led by scientists at York University’s Lassonde School of Engineering has created a model of how methane changes on Mars throughout the day by using data from a satellite, the ExoMars Trace Gas Orbiter and the Curiosity Rover. In the past, each had measured significantly different amounts of methane on Mars. The new measurements provide more clues that could help to understand what processes are important in creating the methane coming from a large 154 km- wide crater on the planet, Gale crater.

Cruise blog: Update on observing seafloor methane seeps at the edge of hydrate stability
Six new posts, including two videos, from the R/V Falkor on its cruise to seek out and study methane bubbles seeping out of the seafloor.

Study shows how to produce natural gas while storing carbon dioxide
New research shows that injecting air and carbon dioxide into methane ice deposits buried beneath the Gulf of Mexico could unlock vast natural gas energy resources while helping fight climate change by trapping the carbon dioxide underground.

Seeking the Seeps
The unusually bright Oregon sun beams down on me as I watch the soaring Astoria bridge recede into the background. The R/V Falkor has just pushed back from the dock and we’re steaming into the great Columbia River. Looking ahead, I can see twin points of land, framing the mouth of the Columbia like a giant crab claw.

Study: U.S. methane emissions flat since 2006 despite increased oil and gas activity
Natural gas production in the United States has increased 46 percent since 2006, but there has been no significant increase of total US methane emissions and only a modest increase from oil and gas activity, according to a new NOAA study.

Chemical tracers untangle natural gas from agricultural methane emissions
With natural gas booming across the Front Range, drilling rigs may operate within feet from cattle farms. That shared land use can confound attempts to understand trends in methane, a greenhouse gas and air pollutant—the gases emitted from these different sources blend together.

Brick by brick
For three weeks, the crew and science complement of the R/V Falkor has sailed down the coast of California, from San Francisco to San Diego. We have worked together to take the ROV SuBastian into the depths, beyond the reach of sunlight and—for now anyway—human intervention.

Hunting Bubbles: Bubbles Found
As we steam towards San Francisco in rough seas, I am reminded how lucky we have been during our time on the Falkor with the weather, never losing any days to poor weather. Falkor really is the luck dragon!

Hunting Bubbles ~ Week Four Video
This week’s #HuntingBubbles video looks at the trial of the ABISS lander and the next steps that the team will take as they reflect on the expedition.

How is a test tube like a layer cake?
By Jen Karolewski If you have ever read a scientific paper, you probably know how dry and dull they can be. As a graduate student I spend a lot of time reading papers and I can say with confidence that the methods section is often the most mind-numbingly tedious part – this is the portion of an article that describes the particular details of where a sample was taken or …

Hunting Bubbles ~ Week Three Video
Two strategies being tested right now on the #HuntingBubbles expedition include rapid prototyping as well as modifying “off the shelf” sensors and instruments to specific scientific purposes.

Seafloor methane expedition: In-situ observations of methane bubbles from natural seeps
Rising methane bubbles from natural seeps can either dissipate in the water column, or “survive” up to the water surface and be released into the atmosphere.

Gas hydrate breakdown unlikely to cause massive greenhouse gas release
The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature.

Scientists try to mitigate methane, from cows
There are about 33 million cattle in Mexico, where a few scientists are experimenting to concoct a cow diet that will reduce methane emissions.

New research explores how wetlands and agriculture could be causing a global rise in methane
New research shows recent rises in methane levels in the atmosphere are most likely driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.
