Tropical Storm Eta had effects on Florida's Gulf Coast beaches, including dune erosion and overwash. This image from the coast cam at Madeira Beach, Florida captured high water levels and resulting overwash of sand onto the patio of the Shoreline Resort. The USGS Coastal Change Hazards team works to predict these types of events to

A quick visit to the western caldera rim provided brief views of Kīlauea's summit lake between rain showers. The lake colors were particularly vibrant today, with a deep blue-green color in the western end (bottom of photo), with dark brown near the center. USGS photo by M. Patrick.

The Wolverine Glacier weather station was installed in 1968, and at 3250 ft is the highest elevation long-term weather record on the Kenai Peninsula. Close up of the new radar precipitation sensor on the top of the pole. The crazy looking thing in the middle of the picture is an aspirated temperature sensor. Have you ever noticed a day where it feels really hot in the sun

The Wolverine Glacier weather station was installed in 1968, and at 3250 ft is the highest elevation long-term weather record on the Kenai Peninsula. In Ocotober 2020, USGS scientists upgraded the power system to a Lithium battery bank and installed a radar-based precipitation sensor (Lufft WS-100) to compare with the weighing based precipitation gage. The new radar-based

The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows a daily snapshot of water-level statistics in the network for October 2020. Please note: starting around October 22^nd

Dr. Ilsa Kuffner of the USGS St. Petersburg Coastal and Marine Science Center and her collaborator Dr. Andrea Grottoli in the School of Earth Sciences at Ohio State University prepare for field work to study endangered elkhorn corals in the Florida Keys along with their team of researchers. They are researching where and why

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. The data document seasonal and spatial patterns in coral growth that correlate with ocean conditions and are used to guide the

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.

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. Waves are an important component of the total water level, which is how high the water

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. USGS scientists at the Wetland and Aquatic Research Center identify and quantify the tiny animals found

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. These data are used to create a beach profile, that shows the shape of the

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.

The Ecomapper is an autonomous underwater vehicle (AUV) that is a specialized submersibile device that operates by propelling through a water body between points along a constant depth.

Geologists discuss the geology of Jurassic rocks in thurst-faulted structures near the southern limit of Western North Slope.

Geologist examines f Faulted and folded petroleum source rocks in Jurassic and Cretaceous rocks (Kingak Shale, pebble shale unit, and gamma-ray zone of Hue Shale) in southern part of Western North Slope. Thermal maturity of these rocks is at the upper limit of oil preservations. Oil odor indicates that oil was generated from these rocks but it likely migrated to other

Oil-saturated sandstone in the Nanushuk Formation in westernmost National Petroleum Reserve in Alaska (NPR-A). Oil in these rocks likely was generated beneath Western North Slope and migrated northeastward into NPR-A.

Geochemists use platinum, silica, and ceramic crucibles, shown here in a glass container called a desiccator.  Silica is used because it is resistant to extremely high temperatures and because it is chemically inert. Silicon, linked up with a pair of oxygen molecules as silicon dioxide, is known as silica.
