  • The goal of the Eastern North American Margin Community Seismic Experiment is to understand the breakup of ancient continents that led to the formation of the eastern edge of North America and the Atlantic Ocean and the later evolution of this continental margin by landslides and other active processes. A record of these geological events is stored in the rocks offshore North Carolina. We will collect active and passive, onshore and offshore seismic data to image geological structures at a range of scales to learn about the evolution of continental margins and their geohazards.

  • We are conducting a seismic program in the Deep Galicia Basin of the northeast Atlantic Ocean west of Spain. The goal of the proposed research is to collect data necessary to study the rifted continental to oceanic crust transition in the Deep Galicia Basin west of Spain.

  • Polar ice is home to large communities of algae that thrive in the frigid Arctic environment, including microscopic bacteria, unicellular algae, diatoms, worms and crustaceans. These tiny organisms have a big impact on the marine ecosystem and the entire planet -- including us. Andy Juhl and Craig Aumack, scientists from Lamont-Doherty Earth Observatory, are in Barrow, Alaska studying algae in and below sea ice, and how our warming climate may impact these important organisms.

  • This is the blog for the NSF-funded project studying climate, fire & forest history in Mongolia led by Neil Pederson of Lamont-Doherty Earth Observatory and Columbia University, Amy Hessl of West Virginia University, Peter Brown of Rocky Mountain Tree Ring Research and Baatarbileg Nachin, head of the Department of Forest Science in the School of Biology and Biotechnology at the National University of Mongolia.

  • Scientists at Lamont-Doherty Earth Observatory have designed a set of ice imaging instruments small enough to hitch a ride on planes flying over both poles on routine missions. This spring, the IcePod will begin collecting data over Greenland from the wing of a New York Air National Guard LC130 plane. IcePod will help scientists to understand how quickly the ice sheets are changing as climate warms and what this will mean for global sea levels.
