The St. Clair River, Lake St. Clair and the Detroit River, also known as the Huron-Erie Corridor, are the international waters that connect Lake Huron to Lake Erie. Environmental changes in the Corridor over time have resulted in a loss of habitat for fish and other organisms. This video is focusing on the successful St.

This clip shows a bat (not identified to species) flying near a turbine as imaged with a camera sensitive to near infrared light. The bat flies in rapidly from the top left, then turns and flies into the spinning rotor blades of the turbine. The bat appears to be deflected upwards by the blades and escapes a direct strike.

Heather Welch, Claire Rose, and Richard Coupe, U.S. Geological Survey scientists involved in the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT) study, outline agricultural effects on water quality in the Mississippi Delta region.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from students at H.D. Woodson High School in Washington, DC. Questions include:

Interview by Richard Coupe (US Geological Survey) of Jeannie Barlow-- a scientist involved in the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT)-- on groundwater/surface-water interaction.

Watch video interviews with four people discussing their experiences near the epicenter of the magnitude 5.8 earthquake in central Virginia on August 23, 2011. Tens of millions of people in the eastern U.S. and southeastern Canada were startled by sudden ground shaking from this earthquake, which was among the largest to occur in this region in the last century.

Interview by Richard Coupe (U.S. Geological Survey) of Heather Welch-- a scientist involved in the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT)-- on her research results on environmental effects of biofuel production.

Richard Coupe (U.S. Geological Survey) summarizes research results of glyphosate and water quality as part of the the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT).

Interview by Richard Coupe (US Geological Survey) of Claire Rose- a scientist involved in the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT)on research results of metolachlor transport.

Interview by Richard Coupe (U.S. Geological Survey) of Richard Rebich-- a scientist involved in the National Water Quality Assessment (NAWQA) Study of Agricultural Chemical Transport (ACT)-- results of SPARROW Modeling. SPARROW is a a modeling tool for the regional interpretation of water-quality monitoring data.
