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.

Static stress change models for known or hypothesized faults in the Hispaniola and Puerto Rico subduction segments due to (a) slip on a patch of the Puerto Rico subduction zone, and (b) slip on a patch of the Hispaniola subduction zone. An open arrow denotes slip direction and the patches are marked by dashed rectangles.

Understanding the forces that influence major floods can help inform the design of more resilient infrastructure. Image shows a major flood on the St. John River on the border of Maine, United States and New Brunswick, Canada, April 29, 2008. This site was part of the study. USGS Public Domain.

Alligators are very abundant in the freshwater wetlands of Everglades National Park and can usually be seen along the Anhinga trail in the park, especially when water levels are low.  This ~5-foot gator is resting on exposed limestone bedrock alongside the trail.
