A map showing the epicenter of the M 3.5 quake that occurred 3.7 miles (6 km) east of Elgin, South Carolina on June 29, 2022. The quake is part of an ongoing sequence in central South Carolina. The sequence started on December 27, 2021, with an M3.3 earthquake near Lugoff, South Carolina.

An illustration of a mountain with water flowing from the top down to a river with smaller rivers flowing off the sides. Multiple items appear along the various rivers including leaky weirs, one rock dams, log dams, gabions, check dams, trincheras, and earthen berms. Informational bubbles appear alongside these various item in the illustration.

USGS hydrologists and hydrologic technicians test a new method for collecting water from the Millstone River in Blackwells Mills, New Jersey. The new method helps measure microplastics concentrations using representative cross-section sampling. In the background, USGS staff maneuver a stainless-steel pump and tubing at pre-determined points along the river.

In June 2022, Mendenhall Fellow Sabine Loos (Research Civil Engineer in the Geological Hazards Science Center) presented a seminar to USGS's Earthquake Science Center at Moffett Field, CA, where Max Schneider (Research Statistician) works as a Mendenhall Fellow.

Bruce Bernard (left) and Scott McBride (right) obtain water and sediment samples at Egmont Key which is about 1 mile west of the mouth of Tampa Bay in the Gulf of America. Samples were collected June 14, 2010 prior to the possible occurrence of oil contamination from the Deepwater Horizon's oil well.

Researchers from the USGS, NASA, and NAU gather around a small simple esker and ephemeral lake deposits.  The team used sedimentology, geochemistry, and remote sensing to characterize these features on Earth before comparing them to Mars.

Survey area for low-flying helicopter soon to be visible in six Montana counties, including Helena, the Elkhorn Mountains, Bull Mountain and the Tobacco Root Mountains.

In this photo, a group of 20 scientists pose for the camera. The group is dressed in winter gear and stands in front of Berthoud Pass, Colorado. The pass and the ground are covered in snow. Berthoud Pass has a few patches of dark green trees.

In order to get accurate measurements, the Snow to Flow scientists collect several kinds of data using a few different tools. Evan and the team dig snowpits and collect snow depth, snow density, and weather data. They also place sensors across the snowpack to help the drones collect accurate data.

In the snowpit, Evan collects snow depth, snow density, and weather data at Berthoud Pass, CO.

Two photos are arranged side by side. In the first photo, the photographer stands at the bottom of the snowpit. We can see how deep the snowpit is – about the length of a ski from tip to tail. There is a shelf dug into the side of the pit that holds science gear.

Mark communicates with the ground team (including Evan and Andy) to let them know that the USGS UAS is starting its flight over the snowpack.

Victoria Scholl, USGS Physical Scientist. This graphic shows a quote from Victoria’s narrative. It reads: “My background is in imaging science: the capture, processing, display, and analysis of imagery.“ Yellow quotation marks bookend her quote.

Mark checks the spatial data downloaded from the drone to make sure that the first UAS flight accurately collected snowpack data.

The ground penetration radar is set up on a sled, ready to be pulled behind a skier. The sled is covered in blue canvas. The radar is a combination of yellow and black computer gear and a neon green foot-long sensor. Yellow crates and skis dot the background of the image.

Andy Creighton, USGS Hydrologist. A photo shows USGS scientist Andy Creighton smiling at the camera. Andy is on a pair of dark skis posing in a filed of snow. Behind her, rocky mountains are dusted in snow and evergreen trees. Andy is wearing bright snow gear that includes yellow ski boots, red ski pants, a turquoise hoodie, and a yellow backpack.
