Suzanne Carbotte, Ph.D. Doherty Research Scientist Lamont-Doherty Earth Observatory John Diebold, Ph.D. Senior Research Scientist Lamont-Doherty Earth Observatory G. Michael Purdy, Ph.D. Director Lamont-Doherty Earth Observatory A New Era in Ocean Exploration:
Introducing Research Vessel Marcus G. Langseth Oceans cover about three quarters of the Earth's surface. Although much has been learned about the seafloor and sub-floor in recent decades, much remains to be explored. The panel will describe a wide range of ship operations and scientific investigations of Lamont's newest ocean-going research vessel, the 235-foot Marcus G. Langseth.
This lecture is sponsored by the Lamont-Doherty Alumni Association. |
Sunday, March 25 Dallas Abbott, Ph.D. Adjunct Research Scientist Cosmic Impact! Evidence from Madagascar A tsunami wave as high as a 30-story building. Ocean water vaporized, seafloor rock and shells melted, and unprecedented torrential rains. What could cause such an event? Did it ever actually happen?

Sunday, April 15 Click on the image above to watch a video of this lecture. Roger Buck, Ph.D. Doherty Senior Research Scientist Lamont-Doherty Earth Observatory From Satellites to Camels: In East Africa Studying the Biggest Magmatic Rift Event Ever Seen In September 2005 a 40-mile long crack opened in the Earth. Satellite images showed that this was the largest magmatic rifting event ever seen. Is the African continent splitting at the seams? Roger Buck will describe the science behind the cracking event and similar ones in Iceland, and will share his experiences traveling and working in this remote and dangerous desert area at the sourthern end of the Red Sea. |
Sunday, April 22 Meredith Kelly, Ph.D. Post Doctoral Research Fellow
Meredith Nettles, Ph.D. Post Doctoral Research Scientist Climate Change in Greenland: Perspectives From the Present and Past Determining what caused significant and abrupt climate changes in the past is essential for understanding current and future climate change. The extremely rapid response of earth systems to global warming continues to surprise researchers, particularly in the Arctic. This lecture will discuss the stability of the Greenland Ice Sheet because of its potential incluence on global sea level and ocean circulation. Meredith Kelly will discuss past climate changes as recorded by Greenland glaciers. Meredith Nettles will discuss the effects of present global warming on the Greenland Ice Sheet.
