New Tool Can Determine the Sources of Mercury Found in the Great Lakes

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.

Grass Carp Eggs Compromised by Settling on Streambeds

Grass carp egg survival is compromised when they settle on streambeds and are potentially covered by sediments, according to a new study by the U.S. Geological Survey. It has been long assumed that the eggs of Asian carps, including grass carp, must be carried in the water current in order to hatch successfully, but no previous scientific studies have proven that theory.

New Simulations of 1811-1812 New Madrid Earthquakes Show Strong and Prolonged Ground Shaking in Memphis and Little Rock

Computer simulations of earthquake shaking, replicating the quakes that occurred in 1811-1812 in the New Madrid seismic zone (NMSZ), indicate that future large earthquakes there would produce major, prolonged ground shaking.

New Evidence Shows Endangered Pallid Sturgeon Spawned in Lower Missouri River

Three tiny fish larvae that were captured by U.S. Geological Survey scientists in May 2014 have just been confirmed to be pallid sturgeon. These new genetic identifications add to mounting evidence that critically endangered pallid sturgeon spawned successfully in the Lower Missouri River downstream of Gavins Point Dam, South Dakota.

Model Offers More Ease, Precision for Managing Invasive Asian Carp

The likelihood of Asian carp eggs being kept in suspension and hatching in the St. Joseph River in Michigan has been further evaluated using a model that examines a range of multiple flow and water temperature scenarios. Results illustrate the highest percentage of Asian carp eggs at risk of hatching occurs when the streamflow is low and when the water temperature is high.
