Scientists from AIST, JOGMEC, Georgia Tech, and the USGS prepare to analyze pressure cores as part of a multi-year gas hydrates research project in Japan. Left to right: Emile Bergeron (USGS) and Carlos Santamarina (Georgia Tech) watch the movement of a sediment pressure core on a video screen.

Scientists from AIST, JOGMEC, Georgia Tech, and the USGS prepare to analyze pressure cores as part of a multi-year gas hydrates research project in Japan. This photo shows the pressure core storage chambers, which contain hydrate-bearing sediment samples obtained from the Nankai Trough offshore Japan.

Scientists from AIST, JOGMEC, Georgia Tech, and the USGS prepare to analyze pressure cores as part of a multi-year gas hydrates research project in Japan. The cores and pressure vessels are very heavy to move around, so they are using an overhead hoist system with chains to move the devices.

Collapse sinkhole in a salt dome in Daisetta, Texas (September 2008). Salt is particularly susceptible to rapid dissolution causing large bowl-shaped sinkholes. Injection of fluids into this salt dome increased the dissolution of the salt causing a 60-foot deep sinkhole that covered several acres and destroyed many buildings.

USGS technician Jenny White checks instruments on the research vessel Pelican during a cruise that imaged the Gulf of Mexico seafloor in areas with abundant gas hydrates in April and May 2013.

National Wetlands Research Center workers set bench marks to study marsh subsidence.

When the river stops flowing the channel becomes brushy because of the moisture in the river bottom. The location is 17º59'15"N, 66º17'40" and the elevation is 10 m. All photographs are at the same location.
