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. Join us as Sue Powell interviews USGS ecologist Steve Perakis and discusses his research about the

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. 

The U.S. Geological Survey estimates 896 million barrels of conventional, undiscovered oil and 53 trillion cubic feet of conventional, undiscovered non-associated gas within NPRA and adjacent state waters.  The estimated volume of undiscovered oil is significantly lower than in 2002, when the USGS estimated there was 10.6 billion barrels of oil.  The new result, roughly 10

Nutrient sources in both agricultural and urban areas contribute to elevated nutrient concentrations in streams and groundwater across the nation. A new USGS study shows that, despite efforts to control nutrient sources and transport, concentrations of nutrients that can damage aquatic ecosystems and affect drinking water have remained the same or increased in many streams

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. Then, we are joined by former USGS hydrologist Bernie Bonn to learn how chemistry can be used to identify where organic matter in streams comes from in the

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.  This stormwater can also contain fertilizers and insecticides used along roads and on lawns, parks and golf courses.  In a new USGS

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. Libby Jewett

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. Jack

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. Stick around and learn about the water beneath our feet here at the USGS Oregon Science Podcast

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.

USGS South Carolina Water Science Center Data Chief, John Shelton in a special hydrologic expedition down West Africa's Congo River. In part two of this three part episode John describes the trials and tribulations of data collection on the Congo River.

USGS's David Applegate will discuss lessons learned from this year's string of earthquake disasters in Haiti, Chile and elsewhere. Earthquakes and other geologic hazards are an inevitable aspect of life on this active planet, but their impacts on society are not. Hear how USGS is using new science and innovative technology to support emergency responders and help

An impressive chorus of frogs recorded at 9:00 pm on July 1, 2010 at Lake Ramsey Savannah State Wildlife Management Area near Covington, LA. Over the constant staccato "machine gun" call of the Pinewoods Treefrog (Hyla femoralis) you can hear the repetitive nasal "trill" of the Cope's Gray Treefrog (Hyla chrysoscelis) and the frequent sheep-like bleats of the Eastern

According to scientists from the U.S. Geological Survey there is no safe zone of development for the health of urban streams. In a new USGS audio podcast of a Spanish-language interview by Susan Soltero on Radio Walo (Humacao, Puerto Rico), scientists Ana Maria Garcia, Tom Cuffney, and Gerard McMahon note that even the early stages of urban development can negatively

Dennis Lynch, USGS scientist and Department of Interior's Program Manager for the Klamath Basin Secretarial Determination, brings us up to speed on recent developments in the Klamath River Basin restoration. Developments include the signing of two historic agreements that attempt to provide long term solutions to one of the West's most challenging conflicts over how water

You may notice a green, red or brown film on your favorite boating or swimming area in the summer. This coloring could mean that the water is affected by harmful algal blooms. USGS scientists Dr. Barry Rosen, Dr. Jennifer Graham and Dr. Keith Loftin discuss why these blooms can be harmful to people, animals, and ecosystems, as well as what the USGS is doing to better

Early Friday morning of June 11, the  Little Missouri River in Southwest Arkansas experienced a deadly flash flood, with waters that rose over 20 feet in just 5 hours. In response, the USGS deployed a team of scientists to study the flow and height of the water, which is crucial for forecasters and emergency responders to warn the public, improve planning efforts

Prescribed burns are a common tool used by land managers to control invasive plant species and to promote native plants. There are many benefits to using a prescribed burn as a management tool; however, controlling fire is often difficult as it can be unpredictable. FRESC research ecologist Dave Pyke sat down with us to speak about a new framework that he has developed for
