Bend a rock. Channel your historic ‘birthquake.’ Check out rocks, fossils, sediment cores and more at Lamont’s Open House on Saturday, October 11.
Climate scientist William D’Andrea of the Lamont-Doherty Earth Observatory asked young scientists attending a symposium last October, “What do you wish everyone knew about climate change?” He turned the responses into this video, which covers the topic pretty well.
Ten years ago, hydraulic fracturing barely existed. Today 45,000 fracked wells produce natural gas, providing energy for millions of homes and businesses, and nearly a quarter of the nation’s electricity. But scientists are far behind in understanding how this boom affects people near wells. Geochemists Beizhan Yan and James Ross of Columbia University’s Lamont-Doherty Earth Observatory are trying to fill in this gap.
No one ever leaves the field the same way they entered it. Yes there is a new layer of mud on equipment, the expected wear and tear on your gear and your physical being. But also, an intangible shift in perspective.
Geochemists Alexander van Geen and Jacob Mey helped coauthor a recent paper in the leading journal Science showing that warming climate in the future may not degrade oxygen supplies in some parts of the oceans as previously thought.
Lamont-Doherty Earth Observatory graduate student Natalie Accardo recently returned from Tanzania and Malawi, where she installed seismic instruments in both countries alongside Lamont seismologists Donna Shillington and Jim Gaherty. Natalie produced this video, which shows the scientists and their Tanzanian colleagues conducting a “stomp test” at one of their sites in the Tanzanian village of Manda.
Geologist Nicholas Christie-Blick has studied the Death Valley region for more than four decades. Each spring, he leads a group of Columbia University undergraduates there on a fieldtrip. Check out highlights from this year’s trip.
Postcard from the Field: Lamont-Doherty Earth Observatory graduate student Rajib Mozumder, who works with Lamont scientists Lex van Geen and Ben Bostick, has spent part of his summer drilling water wells and collecting samples in Bangladesh.
Today’s plan is to extend the sampling to include a wider region of the water exchange between Alison (Nanatakavsaup), the surrounding ocean and the connection to Hayes glacier. At the Village Meeting we had queried the local fisherman about the iceberg exit pathways for both Alison and Hayes to confirm or correct information we have gleaned from satellite imagery.
Four years ago this month, archeologists monitoring the excavation of the former World Trade Center site uncovered a ghostly surprise: the bones of an ancient sailing ship. In a new study, scientists at Lamont-Doherty Earth Observatory say that an old growth forest in the Philadelphia area supplied the white oak used in the ship’s frame, and that the trees were probably cut in 1773 or so—a few years before the bloody war that established America’s independence from Britain.
