On Thursday December 3, 2009, the USGS celebrated the 125^th anniversary of topographic mapping at the USGS National Center in Reston, VA.

Hear clips of the celebration in this episode of CoreCast, including the history of USGS mapping, given by Mark DeMulder, director of the National Geospacial Program. Also, Kari Craun, director of the National

The Johnson Creek watershed is an important resource in Portland, Oregon. It forms a wildlife and recreational corridor through densely populated areas of the Portland metropolitan area, as well as rural and agricultural land in Multnomah and Clackamas Counties. However, because of its location within an urban environment, there are often concerns, including worries about

Thanks to a satellite collar, two innovative scientists, and a blog, people can follow the travels of Brutus, the ‘North Pole wolf’ as he leads his pack through the long arctic winter.

Listen as wolf researcher David Mech talks about why he and his team put this satellite collar on Brutus and what they hope to learn about these arctic wolves.

When a 40-foot tsunami wave hit the shores of American Samoa on Sept. 29, 2009, thousands of locals made it safely to higher ground, thanks to education efforts and research.

Listen to an interview with USGS oceanographer and tsunami researcher Bruce Jaffe as he explains why this post-tsunami research is essential for keeping people safe in future tsunamis.

To increase to increase public awareness during Native American Indian National Heritage Month, we will be discussing the anthropology of indigenous peoples in the Aleutian Islands and how continued scientific research can help future forecasting of mega-earthquake and transoceanic tsunami probabilities.

Right now in Florida, non-native, giant constrictor snakes—pythons, anacondas, and the boa constrictor—are being found in the wild, and two species have established several breeding populations. The snakes pose a considerable resource management challenge for agencies charged with preserving native ecosystems and species. USGS research wildlife biologist Bob Reed discusses

Increasing nitrogen emissions from motor vehicles, energy production, and agriculture are being deposited in lakes throughout the world, directly affecting lake biology and associated food webs. Alpine lake ecosystems are especially vulnerable to this deposition. USGS scientist Jill Baron, co-author of two new studies on how increased nitrogen pollution can affect lake

The United States is using less water than during the peak years of 1975 and 1980, according to USGS water use estimates for 2005. Despite a 30 percent population increase during the past 25 years, overall water use has remained fairly stable.

So what else do we know--and not know--about water use in the U.S.? Learn from a USGS scientist and partners, and hear what

Tsunamis are devastating. Usually associated with earthquakes in the Pacific, these giant surges of oceanic water can kill thousands and do billions of dollars of damage in minutes. Surprisingly, most people in Oregon are not aware of the tsunami history and hazard along our very own coast. Listen in as we examine the science of tsunamis and sit down for a special

USGS Menlo Park Science Center, Bldg. 3, Conference Room A, 7:00PM

Several USGS scientists are investigating the problem of fatal bat and bird collisions with wind turbines. USGS scientist and bat specialist Dr. Paul Cryan at the Fort Collins Science Center chats with Juliette Wilson about whether we can have our wind turbines and healthy populations of bats and birds too.

USGS Scientists Jim Cannia and Jared Abraham discuss the use of geophysics, a powerful new tool, in water resources studies in Nebraska

USGS North Carolina Water Quality Specialist Mary Georgino discusses The Triangle Area Water Supply Monitoring Project.

USGS South Carolina Water Science Center Research Ecologist Dr. Paul Bradley discusses USGS Toxic Substances Research on emerging contaminants in rivers and streams.

Host Leslie Gordon interviews three USGS earthquake scientists, David Oppenheimer, Carol Prentice, and Tom Holzer about the scientific advances made in the last 20 years since the Loma Prieta earthquake struck northern California. Oppenheimer, Holzer and Prentice discuss the work they did immediately after the quake in 1989, and how 20 years of scientific and technological

Two large earthquakes have hit the Pacific. Harley Benz, Scientist-in-Charge at the USGS National Earthquake Information Center, talks about the quakes' damage, their relationship to one another, and what USGS scientists are doing in the aftermath.

Interview with USGS scientist Dr. Roger Clark about his Sept. 24 Science article that suggests water exists on the moon. Imaging spectroscopy led Clark and others to this discovery which opens the possibilities into further moon exploration.

Better late than never, here's a proper introduction to the USGS Oregon Science Podcast. Learn about who we are, what we do, and what you can expect from us in the future. Plus, as an added bonus, get a teaser for what's coming next month.

USGS North Carolina Water Science Center Director Jerad Bales discusses Hurricane Floyd and flood impacts on North Carolina in 1999.

Did you know that natural resources like coal can have impacts on human health?

USGS Energy Resources Program Coordinator Brenda Pierce discusses an emerging area of study called ‘medical geology’ and the connections between natural resources and human health. We also hear from USGS scientists Bill Orem and Calin Tatu, who are researching links between coal and a

Geologic maps record the distribution of rock and soil materials at Earth's surface and help decision makers identify and protect valuable resources, avoid risks from natural hazards, and make wise land use choices.

Randy Orndorff, Associate Program Coordinator for the USGS National Cooperative Geologic Mapping Program, talks about the grant for the academic
