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 Formation.

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. Second is Mark Benthien, who is the Director of Communication, Education and Outreach with the Southern California Earthquake Center and also coordinates the Great ShakeOut worldwide.

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.

The wet, subtropical wilderness of Everglades National Park is home to a diversity of Floridian wildlife, but one invader is causing severe changes in these native animal populations. Many of the park’s mammals are declining dramatically as a result of invasive Burmese pythons, according to a recent study by U.S. Geological Survey scientists and partners. Mid-sized mammals such as foxes, rabbits, and raccoons that were previously populous in the Everglades are the most severely affected. USGS scientist and co-author Robert Reed to discusses the Burmese python situation and what these mammal declines mean for the Everglades ecosystem.

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. As a watershed becomes covered with pavement, sidewalks, and other types of urban land cover, stream organisms are confronted with an increased volume of storm water runoff, increased exposure to fertilizers and pesticides, and dramatic changes in physical living spaces within the stream itself. In this episode, USGS scientist Jerry McMahon describes two take home messages for managers.
