Max Cunningham, a graduate student at Lamont-Doherty, traveled to Costa Rica’s Mount Chirripó this past summer to test the idea that mountain glaciers carved the summit we see today. He and his colleagues hope to eventually pin down when Chirripó’s high-elevation valleys eroded into their current form. Check out a recap of their 2014 field season.
How did big crystals of blue quartz get locked into the pink granite of Mudd Hall? David Walker of the Lamont-Doherty Earth Observatory continues his Columbia Geology Tour.
The Columbia Geology Tour, Part 2: Take a trip back 350 million years to the shallow seas of the Mississippian that covered what is now the U.S. Midwest — source of the finely crafted limestone columns and facade details of St. Paul’s Chapel.
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.
The Khumbu Icefall on Mount Everest is perhaps the most well-known and notoriously dangerous glacial feature on the planet. In a fresh post on the Glacier Hub blog, the Earth Institute’s Ben Orlove, writing with anthropologist Pasang Yangjee Sherpa of Penn State, recounts a recent workshop held in Kathmandu to address the issues raised by the tragic deaths last spring of 16 Nepalese guides who were preparing the trail for this year’s climbing expeditions.
For the last decade or so, Columbia University geologist David Walker has led students and colleagues on a tour of the geologic gems hiding within Columbia’s campus. Along the way, Walker finds evidence of how life on Earth has evolved over 4.5 billion years.
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.
When viewing The Great Unconformity,
The result of a vast denudation,
One feels a new sense of enormity …
And above it lie critters crustacean!
Each fall, the Earth Institute Practicum offers a broad survey of the applications of frontier research to the practice of sustainable development, taught by top faculty and researchers. The practicum meets weekly on Tuesdays.
