An updated USGS assessment on the economic recoverability of undiscovered, conventional oil and gas resources within the National Petroleum Reserve in Alaska (NPRA) and adjacent state waters is available. Economically recoverable resources are those that can be sold at a price that covers the total costs from finding the resource to getting it the market.

2011 had been predicted to be a particularly bad year for flooding in the northern Plains and upper Midwest. Areas along the Red River in North Dakota and Minnesota and the James Rivers in the Dakotas are still experiencing flooding from snowmelt. Now extreme rainfall is causing severe flooding along the Mississippi and Ohio Rivers.

Earthquakes – and large ones at that – threaten to shake residents and buildings of the central and eastern United States, a reality that scientists, emergency responders and others hope to drive home during the bicentennial of the 1811 and 1812 New Madrid earthquakes.

Since its creation in 1882, the USGS Library has grown to become the world's largest library dedicated to earth and natural sciences, holding more than 1.5 million volumes and 800,000 maps. Richard Huffine, Director of the USGS Libraries Program, will highlight some of the rarest, most valuable, and significant materials held by the USGS.

Randall Orndorff, Director of the Eastern Geology and Paleoclimate Science Center, discusses how Karst affects daily life. Beneath a quarter of the United States are rock types that can dissolve to form caves, sinkholes and other features. Nearly every state has rock layers of limestone, gypsum, and other soluble rocks we call ‘karst’.

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.

Groundwater is not a single vast pool of underground water; rather, it is contained within a variety of aquifer systems. Each of these aquifers has its own set of questions and challenges.

Walruses are important to human communities bordering the Chukchi and Bering seas in the United States and Russia, and the status of walrus provides information about the health of these highly productive marine ecosystems.

A 6.3 magnitude earthquake struck the south island of New Zealand near Christchurch on February 21, resulting in 75 lives being lost. This earthquake was an aftershock from the Sept. 4th magnitude 7.0 earthquake that occurred in nearby Darfield last year. So why did this lesser magnitude earthquake result in more damage and lives lost?

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion.

Beginning on Christmas Eve, 1861, and continuing into early 1862, an extreme series of storms lasting 45 days struck California. The storms caused severe flooding, turning the Sacramento Valley into an inland sea.

In this month’s episode we discuss how 3-D modeling is used to examine groundwater in the Columbia Plateau. USGS hydrologist Erick Burns describes how his team modeled the 53,000 mi2 plateau, how this information is currently used, and what implications it has for the future.
