  • Earthquakes, floods, sea-level rise and sudden shifts in river courses threaten many of the 150 million Bangladeshis living in the low-lying Brahmaputra River delta. Scientists from Lamont-Doherty, Dhaka University and other institutions have begun a five-year project to understand the hazards and the possible hidden links among them. Lamont seismologist Michael Steckler keeps us up to date on the work.

  • Scientists from Lamont-Doherty and Indiana University-Purdue are camping by the Transantarctic Mountains, studying exposed rocks near the edge of the Antarctic ice sheet for clues to how the ice shifted in the past. They hope the geological record will help us understand the effects of a warming planet today. Mike Kaplan, Kathy Licht and others report from the field, and answer readers‚ questions, with help from Gisela Winckler at Lamont.

  • The Dec. 13-17 meeting of the American Geophysical Union, in San Francisco, is the world's largest gathering of earth and space scientists. Scores of researchers from the Earth Institute will give presentations. Read about it here.p>

  • Formerly a lover of the colder temperatures of the Arctic, Brendan Buckley has somehow found his life's work in the tropics. Through his Asian tree-ring record spanning more than 700 years, he is able to study past climate variability and the societal reactions to these changes. As our planet begins to warm and the climate becomes more volatile understanding the past is critical for understanding the future.

  • South Africa is the world’s top producer of platinum, used in everything from jewelry to catalytic converters. Most of it comes from a geological formation the size of West Virginia, called the Bushveld igneous complex, created two billion years ago as molten lava from Earth’s mantle bubbled to the surface and cooled. Lamont-Doherty graduate student Jill VanTongeren is traveling through the Bushveld collecting rocks to learn more about how this unique and mineral-rich region formed. Read about her work here.
