Damage 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.

Paleoecologist Dr. Lynn Wingard highlights the unique aspects and restoration challenges of the Greater Everglades Ecosystem of southern Florida. Development and water management practices have profoundly altered this ecosystem, endangering much of the animal life in the area.

The USGS recently completed sampling for the North American Soil Geochemical Landscapes Project on November 18, 2010. The last three samples of a total of 14,400 samples were collected at Bull Run Mountain in Virginia.

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.

USGS Associate Director Jason Lambrecht talks about WaterAlert, a new USGS notification system used by managers, recreators, and many others.

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.

Listen to intern Nicki Devanny of Ohio describe the hands-on experience and knowledge she gained for her experience working as a Student Conservation Association (SCA) intern at Bill Williams River NWR in Arizona.

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.

Nutrient sources in both agricultural and urban areas contribute to elevated nutrient concentrations in streams and groundwater across the nation.

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.

This month the USGS Oregon Science Podcast contains two interviews. First, we sit down with USGS hydrologist Stewart Rounds to discuss the effect dams have on water temperature in the rivers of the Willamette Valley.

According to scientists from the U.S. Geological Survey storm runoff from heavier than normal rainfall this fall in Puerto Rico has contributed to large streamflows in urban streams.  Impervious surfaces convey stormwater rapidly to streams.

Earlier this month, a new interagency report was delivered to Congress that warns of the growing threat of low oxygen ‘dead zones’ in coastal waters around the U.S. This condition is known as hypoxia — where oxygen levels drop so low that creatures in the water are stressed or killed. In this episode, we hear from two of the scientists behind the report: Dr.

In this podcast, two New Mexico ranch owners share their experience taking part in a U.S. Fish and Wildlife Service partner’s project for land improvement and receiving money from the government through the Recovery Act.

Recent news reports have brought worldwide attention to Afghanistan's mineral wealth and to the difficulties in bringing a range of commodities to market to rebuild that troubled land. But the mineral assessment is only a part of the story. Recent work by the USGS, the U.S. Navy, and others has made Afghanistan's subsurface among the best known places on Earth. Dr.

This month we highlight a new interactive map that allows users to determine the depth to groundwater at any location in the Portland Metropolitan Area, Oregon. This month's episode features an interview with the groundwater project's lead author, USGS hydrologist Daniel Snyder.

This morning the Washington D.C. Metro area was awakened by a 3.6 magnitude earthquake which struck near Germantown, Maryland and was widely felt throughout the region. We spoke with Mike Blanpied, of our Earthquake Hazards Program, about the details related to this event, why it was felt so widely, and what people can do to prepare around the region.
