The Interaction of Climate Change and Methane Hydrates

Read article

The USGS Gas Hydrates Project has been making contributions to advance understanding of US and international gas hydrates science for at least three 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 (especially the U.S. Department of Energy) 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.

Gas Hydrates Research

The USGS Gas Hydrates Project focuses on the study of natural gas hydrates in deepwater marine systems and permafrost areas.

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 
  • 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 several laboratories focused on hydrate-bearing sediments.

Gas Hydrates - Primer

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.

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.
