Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys. Pictured here is one of 30 stations located in in Dry Tortugas National Park.

Bedding features in the core from the USGS Gulf Coast #4 Bonham borehole, in the Eagle Ford Group mudstones from a depth of about 401 feet, Fannin County, Texas. The Eagle Ford Group lies underneath the Austin Chalk and serves as the source rock for much of the Austin Chalk's petroleum.

This screenshot was taken from a video created for the virtual 2020 St. Petersburg Science Festival that discussed Coastal Change Hazards research at the USGS. Justin Birchler is seen walking up the beach with GPS equipment to measure the elevation of the beach.

To help study the biodiversity present in the deep sea, scientists collect sediment cores. These cores are about a foot long and provide a vertical profile of deep-sea sediment, or mud.

Waves are the motion of the water's surface, usually caused by the transfer of energy from wind. Wave energy causes the water to move in a circular motion. The height and length of these waves combined with the slope of the beach influence how high the water can reach up on the coast.

Map of Yellowstone National Park adapted from Christiansen and others (2007). The pink regions are rhyolite flows erupted within Yellowstone caldera; these flows contain 5% to 15% crystals by volume. The purple region is the Obsidian Cliff flow, which contains close to 0% crystals.

An enigmatic outcrop of 5 million year old basalt sits 300 meters above the Deschutes and Columbia rivers. USGS scientists are carefully studying this basalt flow to determine if it came all the way from central Oregon, 160 kilometers away.
