The USGS Gas Hydrates Project focuses on the study of natural gas hydrates in deepwater marine systems and permafrost areas.
Science Center Objects
The USGS Gas Hydrates Project focuses on the study of natural gas hydrates in deepwater marine systems and permafrost areas. The primary goals are:
- Evaluate methane hydrates as a potential energy source
- Investigate the interaction between methane hydrate destabilization and climate change at short and long time scales, particularly in the Arctic
- Study the spatial and temporal connections between submarine slope failures and gas hydrate dynamics
The Gas Hydrate Project conducts multidisciplinary field studies, participates in national and international deep drilling expeditions, and maintains a laboratory program focused on hydrate-bearing sediments.
The USGS Gas Hydrates Project focuses on gas hydrates in the natural environment and seeks to advance understanding of (a) the potential of gas hydrates as an energy resource; (b) the role of gas hydrates in climate change, as well as their susceptibility to climate change; and (c) gas hydrates and the stability of submarine slopes. The Gas Hydrates Project maintains an extensive laboratory program to support research in these core areas.
The USGS Gas Hydrates Project has been making contributions to advance understanding of US and international gas hydrates science for over two decades. The research group working on gas hydrates at the USGS is among the largest in the US and has expertise in all the major geoscience disciplines, as well as in the physics and chemistry of gas hydrates, the geotechnical properties of hydrate-bearing sediments, and the biogeochemistry of marine and permafrost gas hydrate systems. The group includes field-based scientists, numerical modelers, laboratory scientists, and supporting technical personnel for marine, permafrost, and laboratory operations. Much of the research is carried out in collaboration with other federal agencies or academic partners, and there are frequently opportunities to collaborate on international programs that jointly serve the Project's mission and the goals of the international partners.
The USGS Gas Hydrates Project integrates across USGS mission areas, programs, and regions. The stars indicate the locations of personnel involved in the Gas Hydrates Project. Within the US, much of the research focuses on the Gulf of Mexico and Alaska, which represent marine and permafrost-associated settings for gas hydrates, respectively.

What is Gas Hydrate?
Gas hydrate is an ice-like crystalline form of water and low molecular weight gas (e.g., methane, ethane, carbon dioxide). On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost. Gas hydrates have also been inferred on other planets or their moons.
At the molecular level, gas hydrate...

Hydrate formation on marine seep bubbles and the implications for water column methane dissolution
Methane released from seafloor seeps contributes to a number of benthic, water column, and atmospheric processes. At seafloor seeps within the methane hydrate stability zone, crystalline gas hydrate shells can form on methane bubbles while the bubbles are still in contact with the seafloor or as the bubbles begin ascending through the water column...
Fu, Xiaojing; Waite, William F.; Ruppel, Carolyn D. Estimating the impact of seep methane oxidation on ocean pH and dissolved inorganic radiocarbon along the U.S. mid‐Atlantic Bight
Ongoing ocean warming can release methane (CH4) currently stored in ocean sediments as free gas and gas hydrates. Once dissolved in ocean waters, this CH4 can be oxidized to carbon dioxide (CO2). While it has been hypothesized that the CO2 produced from aerobic CH4 oxidation could enhance ocean acidification, a previous study...
