The waveforms of the ground motion recording and the pressure sensor recording from a station with both types of instruments (see second image above) match up, indicating that the pressure waves are causing the ground (crust) to deflect.

This USGS map shows the number of PFAS detected in tap water samples from select sites across the nation. The findings are based on a USGS study of samples taken between 2016 and 2021 from private and public supplies at 716 locations. The map does not represent the only locations in the U.S. with PFAS.

What can you do to conserve the birds and the bees, even in the face of climate change? In some cases, small actions, such as maintaining a pollinator garden or avoiding pesticides can be important. Take the rusty patched bumble bee, once one of the most common pollinators in eastern North America.

An infographic highlighting a study finding that black carp, which are an invasive fish species in North America, are now known to be established in the wild in parts of the Mississippi River basin. The infographic was created by the USGS. The USGS was one of the study’s co-authors and the research was led by Southern Illinois University.

A map of black carp observations in the Mississippi River basin reported to the USGS Nonindigenous Aquatic Species database as of November 30, 2022. This map is not a complete representation of species abundance or distribution. These data include incidental captures by the public and reports from federal and state agencies.
