USGS Public Lecture Series: Hurricanes and Our Changing Coasts

Wed, 2 Sep 2009 00:00:00 EST

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.

USGS Public Lecture Series: Watching Nature's Clock: A Citizen-Scientist Effort to Track Seasonal Signs of Climate Change

Fri, 5 Jun 2009 00:00:00 EST

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.

USGS Public Lecture Series: A Field Trip to the Congo--Hydroacoustic measurements in "the river that swallows all rivers."

Wed, 3 Jun 2009 00:00:00 EST

Imagine yourself in central Africa, in a dugout canoe crossing the lower Congo Rive''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.
