Amphibians’ permeable skin makes them incredibly sensitive to changes in their environment. Scientists and conservationists alike are using them as “sentinel species” that could provide early warnings of ecosystem change and stress affecting them and other organisms. Next time you are out, stop and listen. Do you hear them?

A worldwide earthquake drill, known as the Great ShakeOut, will be held on Thursday, October 17 at 10:17AM local time. The drill is your chance to practice how to protect yourself in the event of an earthquake. Mike Blanpied, the Associate Program Coordinator for the USGS Earthquake Hazards Program, and Mark Benthien, the Director of Communication, Education and Outreach

An interview with USGS scientist David Krabbenhoft about an article he co-authored in Science about global change's effects on mercury around the world.

An interview with USGS scientist emeritus Richie Williams about his career studying the Earth's cryosphere with remote sensing technology.

On April 30, 2013, USGS released an updated assessment of the Bakken Formation of North Dakota and Montana as part of the National Oil and Gas Assessment. We are joined by USGS Energy Resources Program Coordinator Brenda Pierce and Bakken Assessment Lead Stephanie Gaswirth to learn more about the assessment itself; why it was performed; and some context for the Bakken

Birds and insects at a pond at St. Marks National Wildlife Refuge (Florida) April 2013 at 6:00am

Severe weather season is upon us. Director of the USGS Nebraska Water Science Center, Robert Swanson, and National Weather Service Hydrologist David Pearson discuss tools to stay connected and the importance of having a safety plan in the event of severe weather.

February 2013 public lecture, presented by David Powars

Director of the USGS Nebraska Water Science Center, Robert Swanson, discusses how the drought of 2012 unfolded in Nebraska, the fallout, and what put this drought in a class with other major droughts during the past 100 years.

The next Great ShakeOut earthquake drill will be held on October 18, 2012. During the drill, participants will ‘drop, cover, and hold on’ to practice how to protect themselves during an earthquake.

To give us some details on ShakeOut, we are joined by two guests. First is Mike Blanpied, who is the Associate Program Coordinator for the USGS Earthquake Hazards Program

When bats detect an insect from returned echolocation calls they rapidly increase the pulse rate and raise the frequency of calls in order to gather more information on the insect including location. These calls emitted right before a bat closes in on an insect are called terminal phase calls or "feeding buzzes". The frequency is well above human hearing capabilities at 65

In this episode, high school students from Rosemary Anderson High School in Portland, Oregon, visit the USGS Oregon Water Science Center for a ‘Science Career Day’ event. Scientists work with the students and try to promote the appeal and benefits of a career in science. The day is broken up into two parts: an early morning discussion period, and an afternoon field period

A year after the August 23, 2011 Virginia earthquake, USGS geologist Dr. Mike Blanpied discusses whether a similar event could occur again in the region in the near future, and in an earthquake, what you can do to stay stay safe.

A year after the August 23, 2011 Virginia earthquake, USGS geologist Dr. Mike Blanpied discusses USGS efforts currently underway to learn more about the cause of the event. Dr. Blanpied discusses how scientists are using the August 23 earthquake to inform estimates of the region's seismic hazard.

In this episode, we talk about organic carbon. The benefit of studying carbon extends to many issues, including tracing mercury contamination or investigating disinfection by-products in drinking water treatment. It is amazing what can be discovered by monitoring the volume and flux of carbon through the environment. Learn about the biogeochemistry of carbon from USGS
