Amy Leventer       I continue to enjoy life here at Colgate, dividing my time between teaching and research. My teaching efforts are primarily focused on introductory level courses, such as Oceanography, Environmental Geology, Earth and Environmental Processes, and my core Scientific Perspectives course, Climate Change and Human History. My favorite, however, is time spent out west with the Geology Off Campus program; Dinosaur Ridge, the Moab Fault, and now, Golden Gate Canyon State Park (near Boulder) are all spectacularly beautiful places to teach and a great way to start each summer.       My research in Antarctica is now focused on the impact of modern day global change on this very sensitive system. In particular, I've been studying the northeastern Antarctic Peninsula where the 2002 collapse of the Larsen B ice shelf has made news headlines (and is featured in a Hollywood movie!). Our working group, which includes faculty and undergraduates from several schools in addition to many Colgate students, has shown that this recent collapse is unprecedented over the past 10,000 years. Global warming certainly is having a significant effect on Antarctica.       In addition to our paleoclimate work, our group has been lucky, with two fortuitous discoveries over the past two years. During our 2004 cruise, we discovered a small seamount that appears to have been active recently. And this past season, we discovered a seafloor chemotrophic ecosystem, with bacterial mats and big clams, beneath the collapsed Larsen B Ice Shelf. This cold seep community is the first to be found in Antarctica; its future is uncertain as debris from the ice shelf and organic material from the water column begin to bury it.       In my free time, I've been trying to introduce my family to geology - a week in Yosemite last summer and another week this summer in Moab! We also love spending time in the Adirondacks, up at Colgate's Camp on Saranac Lake.
