Subduction Top to Bottom 2 (ST2B-2) Taking Shape in GEOSPHERE Subduction zones are where lithosphere is recycled into Earth’s mantle along ~55,000 km length of convergent plate margins (at
Hydrothermal vents at the sea floor offer clues to the origins of life on earth, and beyond. Before life on earth, what was there? To be alive is to ponder that question and, perhaps, its natural
Armed with GPS-enabled iPads and infrared surface temperature thermometers, students in an urban high school in Pennsylvania fan out on their school property to take temperature readings of grass,

Geologist David Anastasio, together with a team of Lehigh students, traveled last fall to northern Spain to examine rock formations as part of an effort to better understand the time-based variation
EES faculty member embarks on a voyage of discovery at Earth’s deepest depths by Jennifer Marangos Jill McDermott makes a habit of boldly going where few have gone before. An assistant professor in
Global peatlands store large amounts of carbon within a few meters of the atmosphere, and the peatland-atmosphere carbon exchange is of major interest to global change scientists, including Zicheng
Recent and projected increases in global temperatures, associated changes in regional moisture, and changes in the frequency of extreme climatic events have raised concerns about potential rapid
Ken Kodama’s reputation as a preeminent geophysicist and expert in paleomagnetism was affirmed earlier this month when he delivered the Edward Bullard Lecture at the annual meeting of the American
For years, scientists have known that human activities that burn fossil fuels like coal and oil are pumping carbon dioxide (CO2) into the atmosphere much faster than it is removed by natural
