Frontiers of Earth Science
The very latest developments in the world of Earth science with Roland Pease, recorded at the American Geophysical Union (AGU) meeting in New Orleans, where thousands of Earth, atmospheric, glacial, ocean and hydrologic scientists come together to promote discovery in Earth science for the benefit of humanity.Twenty years on, we discuss the enduring lessons from the Hurricane Katrina disaster of 2005, hearing from Lieutenant General Russel Honoré who led the military relief effort, and Roland speaks to Jill Trepanier, hurricane climatologist from Louisiana State University. We also hear about the mouth of the Mississippi River, known as the Bird's Foot Delta, south of New Orleans. Carol Wilson, assistant professor in the Department of Geology and Geophysics at Louisiana State University, tells us how important these wetlands are as storm protections, yet they’re under threat from sea level rise and lack of sediment.Roland takes a look at fifty-thousand-year-old Antarctic ice whilst speaking to Ed Brook, Professor at Oregon State University and director of COLDEX (Center for Oldest Ice Exploration), whose team is searching for ice which is potentially ten million years old. And he speaks to Allison Chartrand, assistant research scientist at the University of Maryland and NASA Goddard Space Flight Center, who has been working to reveal the hidden landscapes of Greenland under the ice. And Bob Hazen, scientist at the Carnegie Science Earth & Planets Laboratory, takes us back to the origins of life on Earth. He is investigating rocks which could be over four billion years old and may contain molecular fragments of ancient life.Presenter: Roland Pease
