Sediment Lab Suite and Carbon Analysis Lab

At our Science Center, we have a suite of laboratories that we affectionately call the "sed lab." The sed lab really consists of 5 labs, arranged next to each other to allow our lab technicians to easily move back and forth between them while processing sediment samples: Sediment Preparation Lab, Fine Particle Analysis Lab, Settling Tubes Lab, Fume Hood Lab, and Carbon Analysis Lab.

USGS science supporting the Elwha River Restoration Project

 

The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington. Coordinated by the National Park Service, restoration of the Elwha River included the removal of two large dams that had blocked salmon and sediment passage for almost 100 years. The largest dam removal in U.S. history began in...

Selenium Hazard in the Salton Sea Environment, Summary of Current Knowledge to Inform Future Science

The effect of selenium (Se) toxicity on wildlife has been known for more than 50 years. The threat of Se contamination gained greater attention from federal agencies in the 1980s due to the observation of embryo deformity and mortality in birds at a National Wildlife Refuge in California. Harmful effects from Se were determined to be connected to irrigation drainage water.

As a result,...
