On April 10, USGS hydrographer Josh Sundberg measures Red River water flowing over the road in East Grand Forks, Minnesota as flood protection walls prevent further flooding.
 

On April 6, USGS hydrographer Spencer Wheeling carries equipment out to measure high water on the Tongue River near Akra, North Dakota. 

The USGS Dakota Water Science Center began their spring flood response on March 9, 2020, when melting snow caused river levels to exceed flood stage at sixteen USGS streamgage locations in eastern South Dakota.  At the height of

USGS hydrographer Chris Broz gets on the cold ground to measure the high-water mark of the Pembina River at Neche, North Dakota.

USGS hydrographer Spencer Wheeling gets equipment ready to collect a flood water-quality sample on the Wild Rice River near St. Benedict, North Dakota. Collecting water-quality samples helps communities assess the sources and fate of contaminants in aquatic systems, to protect and enhance water resources for human health, aquatic health and environmental quality.

USGS hydrographer Brent Hanson wades out in freezing waters to collect flood measurements on the Sheyenne River near Cooperstown, North Dakota. Hanson reads an outside staff, which is a vertical graduated ruler used to calibrate the continuous readings of water level provided by electronic sensors. Water level is important information for communities living adjacent to

A frozen USGS rapid deployment streamgage measures the height of the Maple River near Page, North Dakota. RDGs can be installed on short notice to provide additional information at locations that are normally not gauged.

Map showing ice cover in the Yellowstone region. Light shaded areas bounded by black and red lines indicate areas covered during the Pinedale (about 20,000-15,000 years ago) and Bull Lake (about 150,000 years ago) glaciations, respectively. Blue lines are contours in thousands of feet on the maximum reconstructed Pinedale glacier surface. The circled numbers schematically

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of November 2019.

Each fall, EROS invites its staff scientists and area graduate students to visit for a noontime poster session. The poster sessions offer a change for those researchers to present their results to their peers and get feedback from their fellow scientists. For this episode, we’ll hear about research into biofuels, cloud-friendly Landsat data, shrubland mapping and satellite

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect in the infrared
