• Scientists are preparing ARkStorm for emergency planning and disaster preparedness
• A series of ‘Atmospheric River’ events slams into the West Coast with hurricane force overal several weeks
• Weather models show expected hazards such as floods, landslides, and erosion impacting life and property

Ice shelves are retreating along the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues.

USGS scientist Jane Ferrigno discusses the USGS project that is for the first time studying the entire Antarctic coastline in detail.

USGS North Carolina Data Chief, Jeanne Robbins, provides an overview on hydrologic data collection techniques for North Carolina.

USGS South Carolina Water Science Center Data Chief, John Shelton in a special hydrologic expedition down the Congo River, West Africa. Part one of a three part episode, sets the stage for the trials and tribulations of water investigations for a changing world.

The powerful storms that swept through Southern California dumped a lot of rain in that region, leaving behind the danger of debris flows.

Sue Cannon, USGS research geologist, explains the hazardous situation facing residents in and near the San Gabriel Mountains, how people in the area can respond to these hazards, and what the USGS is doing to respond.

Few would believe the importance of freshwater mussels to scientists here in the Pacific Northwest. These little-known and often-ignored organisms may live for over a century on the bottoms of lakes, rivers, and streams. Freshwater mussels have a story to tell, and researchers have developed a way of ‘reading’ this story.

The aftershock sequence of the magnitude 7 earthquake that struck Haiti on Jan. 12, 2010, will continue for months, if not years. The frequency of events will diminish with time, but damaging earthquakes will remain a threat.

As Haiti copes with the aftermath of the magnitude 7 earthquake, which struck on Tuesday, January 12, 2010, the U.S. Geological Survey is working to gather information that can aid response efforts. Michael Blanpied, USGS Earthquakes Hazards Program coordinator, gives an update on the current situation in Haiti and answers questions about the global picture.

Carcinogenic compounds in a popular pavement sealer are tracked indoors, where they show up in high concentrations in house dust.

Listen as USGS hydrologist Barbara Mahler explains how she and her team identified the link between polycyclic aromatic hydrocarbons in coal-tar-based pavement sealcoat and house dust.

On January 12, 2010, Haiti was struck by the most violent earthquake in a century. Michael Blanpied, associate coordinator for the USGS Earthquake Hazards Program, answers questions about the earthquake, its severe shaking, and the possibility of additional hazards, such as landslides and a tsunami.

Scientists have reconstructed what the climate conditions were 3 million years ago, and are using these data as one of the closest analogs to estimate future climate conditions.

USGS scientists Harry Dowsett and Marci Robinson discuss some of their findings regarding carbon dioxide’s impact, Arctic conditions, and the deep ocean’s system.

• Scientists and volunteers are working to restore the Eastern population of the federally listed whooping crane
• The life history and migration of whooping cranes

A magnitude 5.8 earthquake occurred just south of the California-Mexico border shortly before 11 a.m. on Wednesday, December 30, and shaking from this earthquake was widely felt.

Ken Hudnut, Southern California Regional Coordinator for the USGS Earthquake Program, spends a few minutes filling in some details about this event.

The USGS is investigating the use of Twitter, a popular micro-blogging tool, to collect and analyze citizen accounts of earthquakes around the world. USGS scientists Paul Earle and Michelle Guy discuss this Twitter Earthquake Detection (TED) project.

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

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.

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.

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.

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.

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.

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.
