Laboratory experiments in flowing water using synthetic surrogate Silver Carp eggs demonstrate egg suspension at lower velocities than previously thought, according to a new U.S. Geological Survey study.

Residents and visitors should not be alarmed to witness a low-flying airplane above the broader Iron Mountain-Ralph-Escanaba-Menominee region.

A new study suggests that the degraded breakdown products of oil-spill contaminants in groundwater could be just as important to monitor as the original contamination itself.

Beginning in early April and continuing for approximately two weeks, the U.S. Geological Survey will conduct an aerial survey designed to scan the upper part of the earth’s crust.

A new, interactive tool can help managers make critical water-quality decisions in the Red River Basin of the United States and Canada.

Today, the U.S. Geological Survey and the U.S. Environmental Protection Agency announce Visualize Your Water, a citizen science challenge for high school students who live in the Great Lakes basin and Chesapeake Bay watershed. 

Ann Arbor, MI – The U.S. Environmental Protection Agency registered a sea lamprey mating pheromone, 3kPZS, as the first ever vertebrate pheromone biopesticide in late December, 2015. Like an alluring perfume, the mating pheromone is a scent released by male sea lampreys to lure females onto nesting sites.

U.S. Geological Survey field crews are measuring record flooding on rivers and streams in 12 states across the country. USGS is making preparations for a prolonged field effort along the Ohio and Mississippi Rivers as major flooding will extend well into mid-to-late January, particularly along the lower Mississippi River.

U.S. Geological Survey field crews are measuring near-historic flooding on rivers and streams across Illinois.

Rapid predictions of harmful algal blooms, or large growths of toxin-producing bacteria in water, can help prevent recreationalists from getting sick at Ohio lakes, according to a new U.S. Geological Survey report.

For the first time, land and resource managers in the Great Lakes will be able to distinguish between the various sources of mercury in the environment, a toxic chemical of significant concern in the region. This is thanks to a new tool that “fingerprints” the mercury, developed by the U.S. Geological Survey and the University of Wisconsin-Madison.
