Turbid Coastal Plume of the Elwha River, Washington

The turbid waters of the Elwha River and the coastal waters of the Strait of Juan de Fuca mix directly offshore of the river mouth, forming a large coastal plume.  This plume is easily identified by the cloudiness of the water (or "turbidity") resulting from sediment discharged by the river.  Two large dams on the Elwha River were incrementally removed from 2011 to 2014 to

Who's Your Mama? Conservation Genetics and At-Risk Species

USGS science supports management, conservation, and restoration of imperiled, at-risk, and endangered species. Endangered Species Day is commemorated in May, and we’re taking some time to find out just how one goes about studying at-risk species and what part cutting-edge technologies can play in helping us do the science that informs managers and policy makers. Catherine

Oregon Songbirds: Singing for Their Supper in Evergreen Forests

In this episode we sit down with USGS wildlife biologist Joan Hagar and discuss her recent study on songbirds in the Pacific Northwest. New research indicates a possible relationship between reductions in the abundance of some species of songbird and reductions in the amount of deciduous trees in evergreen forests. Join us, as we demonstrate how Oregon songbirds sing for

Unearthing the Secrets Beneath the Forest Floor

There is a black box hidden beneath the forests of the Pacific Northwest, guarding the secrets to why the trees grow so large! The black box is soil, which harbors immense biological diversity and controls the release of water and nutrients that support the life above ground. Join us as Sue Powell interviews USGS ecologist Steve Perakis and discusses his research about the
