  • What if the warming Arctic climate were to result in more snow? Could decreasing sea ice cover actually drive more evaporation of newly exposed Arctic ocean water into the atmosphere? And could that increased moisture in the air fall on the ice sheet as snow? If yes, will this stabilize the Greenland Ice Sheet, stopping the current movement of ice into the ocean? The Snow on Ice project takes a unique look at Arctic climate, bringing together multi-disciplinary science around the history of the Greenland Ice Sheet. In the summer of 2018, several teams of scientists are traveling to Greenland to sample as they camp alongside the ice.

  • Antarctica’s Ross Ice Shelf covers an area the size of France and measures a few hundred meters thick above the water. It plays a critical role in stabilizing the West Antarctic Ice Sheet, and scientists are concerned about its future in a warming world. In the field, a team of scientists from Lamont-Doherty Earth Observatory, Scripps Institution of Oceanography and the U.S. Geological Survey is flying over the Ross Ice Sheet, using the IcePod—an assemblage of radars and other instruments bolted to the fuselage of a C-130—to study how the ice, ocean and underlying land interact. They call it the Rosetta project, named after the enigmatic stone containing a script in three languages that led to the decoding of an ancient language. Back at home, they are joined by geologists from Colorado College and oceanographers from ESR to work through the data.

  • 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.

  • 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.
