USGS CoreCast

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:

The United States has 169 active volcanoes. More than half of them could erupt explosively, sending ash up to 20,000 or 30,000 feet where commercial air traffic flies. USGS scientists are working to improve our understanding of volcano hazards to help protect communities and reduce the risks.

Landslides occur in all 50 states and U.S. territories, and cause $1-2 billion in damages and more than 25 fatalities on average each year. USGS scientists aim to improve our understanding of landslide hazards to help protect communities and reduce associated losses.

In this episode, we follow a group of students from the Jane Goodall Environmental Middle School on a class trip to Pintail Marsh at the Ankeny National Wildlife Refuge. There they join USGS ecologist Tara Chestnut to investigate and sample for the amphibian chytrid fungus.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from the beautiful Glacier National Park in Montana. Questions include:

In this episode, we are going to investigate more than just the substance "water." We are going to examine what is in our nations' water, how we at the U.S. Geological Survey monitor it, and what tools we have developed to aid those who want to explore more about our planet's most abundant resource. This is the USGS CoreCast.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from Puerto Rico. Questions include:

- Why has the rainy season been so long in Puerto Rico?

- How is global warming impacting the island of Puerto Rico?

In this episode we explore how scientists for the USGS National Water Quality Assessment Program investigate the ecological health of rivers and streams across the United States. Focusing on a recent sampling effort along the Minam River in northeast Oregon, this video highlights USGS sampling methods for fish, macroinvertebrates (bugs), algae, and habitat.

Devastating floods across much of the U.S. were severe and unrelenting during the spring and summer of 2011. When floods happen, USGS crews are among the first-responders.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from North and South Carolina.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from middle and high school students in Mt. Airy, NC.

America has questions about climate change, and the USGS has real answers. Climate Connections is a USGS video series in which some of the world's leading scientists answer climate change questions gathered across the Nation.

American and Canadian scientists head north on a collaborative expedition to map the Arctic seafloor and gather data to help define the outer limits of the continental shelf. Each coastal nation may exercise sovereign rights over the natural resources of their continental shelf.

Development can have negative effects on streams in urban and suburban areas.

This video discusses how scientists have tracked what, when, and how contaminants may reach public-supply wells in four aquifers in California, Connecticut, Nebraska, and Florida.

Whether you drink water from your tap, use electricity or canoe down your local river, chances are you benefit from USGS streamgage information. So what is a streamgage and what does it do for you? This CoreCast episode gives you the inside scoop on your silent superhero.
