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.

For this month’s episode we discuss the water-quality parameter turbidity. More than just a way to measure dirty water, turbidity can serve as a useful indicator of the ecological health of a watershed.

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.

Tattered Wings: Bats Grounded by White-Nose Syndrome's Lethal Effects on Life-Support Functions of Wings
linkDamage to bat wings from the fungus associated with white-nose syndrome (WNS) may cause catastrophic imbalance in life-support processes, and this imbalance may be to blame for the more than 1 million deaths of bats due to WNS thus far. Paul Cryan, USGS bat ecologist at the Fort Collins Science Center, discusses this newly published USGS research.

A trio of USGS scientists has been involved in the excavation and study of a major animal and plant fossil discovery in Snowmass Village, Colo., which provides more than 100,000 years of vegetation and climate records for the area.

This month's episode focuses on one of the most useful geographic tools scientists have for studying our natural world: Light Detection and Ranging, or LiDAR. LiDAR is a powerful data collection technique that can be used to map surface features, even those hidden beneath the dense canopy of Pacific Northwest forests.

The USGS has just released the first-ever nationwide assessment of rare earth elements in the United States. The report estimates total U.S. resources at just under 12 million metric tons, located in significant deposits in 14 states. Keith Long and Brad Van Gosen, the two lead authors of the report, discuss their findings.

There is a black box hidden beneath the forests of the Pacific Northwest, guarding the secrets to why the trees grow so large! The black box is soil, which harbors immense biological diversity and controls the release of water and nutrients that support the life above ground.

The USGS has been contracted to study the yet unknown source of problematic hydrogen sulfide emissions coming from certain household wallboard, which is imported from China and used in some regions of the U.S. USGS chemist Steve Wilson, who is working on this problem wallboard issue with the Consumer Product Safety Commission (CPSC), discusses the project.

Endocrine disrupting chemicals were identified in all of the 11 Minnesota lakes studied by the U.S. Geological Survey, St. Cloud State University and the Minnesota Pollution Control Agency. Female characteristics were observed in male fish in most of the lakes studied. USGS scientists Jeffrey Writer talks to us about what's going on.

The USGS PAGER system now produces rapid estimates of an earthquake's impact, a significant advancement in USGS earthquake information and alerting capabilities. PAGER stands for ‘Prompt Assessment of Global Earthquakes for Response’. Dr. David Wald describes the PAGER system and its new earthquake impact alerting capabilities.
