About USGS
Wednesday January 6, 2010, 7:00 PM "Whoopers" were on the verge of extinction but thanks to some innovative efforts they have a chance at "flying high." Dr. John French will describe the remarkable journey of survival that begins before the whooping crane chicks are even hatched and ends with taking flight behind an ultralight plane along the migratory route. These extraordinary conservation efforts to establish a migratory population of whooping cranes in the eastern United States are the result of countless partners, pilots, scientists and volunteers.

Wednesday, October 7, 2009, 7:00 PM Every year, billions of tons of fine desert dust from the Saharan Desert are transported thousands of miles through the atmosphere to the Americas, Europe and the Near East. Living microorganisms and chemical contaminants such as pesticides and metals are carried along with the dust. What biological and chemical contaminants are hitch-hiking with the dust and how might downwind ecosystems such as coral reefs and human health be affected?

Wednesday, September 2, 2009, 7:00 PM "Glaciers are Earth’s largest reservoir of freshwater. As they change, so does global sea level. Alaska has one of the largest accumulations of glaciers anywhere on Earth outside of the Polar regions. For most of the past half century, Alaska has experienced a significant increase in temperature that has profoundly impacted its glaciers. Join USGS scientist Dr. Bruce F. Molnia to explore the relationship between Alaska’s glaciers, climate, and sea level. Visit a number of Alaskan landscapes and examine their changes on yearly, decadal, and century time scales."

Wednesday, August 5, 2009, 7:00 PM Climate change is an issue of increasing public concern because of its potential effects on land, water, and biological resources. In the next several years, the United States will be challenged to make management and policy decisions as well as develop adaptation and mitigation strategies that will require anticipating the effects of a changing climate and its impacts on humans and ecosystems. The USGS has a well-regarded history in studying these potential effects and understanding climate change science. Powerpoint (28.6 MB) For more information on this topic, visit: |

Wednesday, July 1, 2009 7:00 PM In September 2008, Hurricane Ike destroyed nearly every house in the Gulf-front community of Gilchrist, just north of Galveston Texas. In addition to storm surge and battering waves, the land on which the houses were built contributed to the disaster by changing in shape and elevation. Dr. Sallenger will explain how the coast changes during extreme storms -- such as Hurricanes Isabel, Katrina, and Ike -- and what this means for our coastal developments today and in the future.

Wednesday, June 3, 2009, 7:00 PM Imagine yourself in central Africa, in a dugout canoe crossing the lower Congo River's rapids and whirlpools. USGS scientist John Shelton found himself there this past summer, measuring places where the waters reached a depth of over 700 feet. His measurements indicate that the Congo River is perhaps the deepest river in the world! This discovery was made during data collection to describe the River’s conditions and understand its extraordinarily diverse richness of fish species. In this effort, Shelton worked with a team of scientists from the American Museum of Natural History. To view the public lecture, visit the video on the USGS Multimedia Gallery site.

Wednesday, May 6, 2009, 7:00 PM A new USGS program, the USA National Phenology Network, is recruiting tens of thousands of volunteers to team up with scientists to help track the effects of climate on seasonal patterns of plant and animal behavior. Come learn how you can contribute to this new national effort, by getting outside, and observing and recording flowering, fruiting and other seasonal events. Scientists and resource managers will use your observations to help track effects of climate change on the Earth’s life-support systems.

Wednesday, April 1, 2009, 7:00 PM Combining collaborative field and modeling with various airborne and satellite sensing technologies Dr. Jones measures how land cover and terrain varies across space and through time. Dr. Jones will provide an introduction to these technologies and a sampler of his work to illustrate how this research helps address resource management issues related to climate change, water flow, and habitat condition.
