The Lamont-Doherty Core Repository is both an archive of sediment (some terrestrial), rocks and coral from beneath the ocean floor, and an archive of the digital data pertaining to the material. They are used for research in climate, environment, many other studies, and for education.

Large-scale groundwater pumping is opening doors for dangerously high levels of arsenic to enter some of Southeast Asia’s aquifers, with water now seeping in through riverbeds with arsenic concentrations more than 100 times the limits of safety, according to a new study from scientists at Columbia University’s Lamont-Doherty Earth Observatory, MIT, and Hanoi University of Science.
Deep beneath Alaska’s Aleutian Islands, down where the pressure and temperatures have become so high that rock starts to flow, new continental crust is being born. Scientists have long believed that continental crust forms in volcanic arcs – they know the magma brought up in the arcs’ volcanoes is geochemically very similar to continental crust. The lingering question has been how exactly that happens. While the magma that reaches the surface is similar to continental crust, the lower crust beneath volcanic arcs is quite different from the lower half of continental crust.
As the second most recent ice age was ending and its glaciers began to retreat, the Earth experienced a large, abrupt climate change that shifted the thermal equator southward by about 4 degrees, according to a new study that for the first time tracks that shift in millennial detail, showing how the Northern Hemisphere cooled and the Southern Hemisphere warmed over the span of a few hundred years. The change would have affected the monsoons, today relied on to feed more than half the world’s population, and could have helped tip the climate system over the threshold for deglaciation, said lead author Allison Jacobel.
A new study finds that the Horn of Africa has become progressively drier over the past century and that it is drying at a rate that is both unusual in the context of the past 2,000 years and in step with human-influenced warming. The study also projects that the drying will continue as the region gets warmer. If the researchers are right, the trend could exacerbate tensions in one of the most unstable regions in the world.
Ancient pollen grains that were floating in the air when mammoths roamed Southern California are providing new insights into historic droughts in the region, including how a series of mega-droughts between about 27,500 and 25,500 years ago changed the ecological landscape. A new scientific paper tracks these changes and suggests that warm ocean conditions similar to what we see off Southern California today fueled that 2,000-year stretch of droughts.
A geochemist who studies the workings of the deep earth and their influence on some of the world’s most explosive volcanoes has been awarded a $500,000 MacArthur Fellowship. Terry Plank, a researcher at Columbia University’s Lamont-Doherty Earth Observatory, joins novelist Junot Diaz, war correspondent David Finkel and filmmaker Natalia Almada in this year’s batch of MacArthur Fellows, who will receive $100,000 a year for five years, no strings attached. Maria Chudnovsky, a mathematician at Columbia’s Engineering School who studies the fundamentals of graph theory, also received a genius grant.
In California’s Death Valley, death is looking just a bit closer. Geologists have determined that the half-mile-wide Ubehebe Crater, formed by a prehistoric volcanic explosion, was created far more recently than previously thought—and that conditions for a sequel may exist today.
The Hudson River that explorer Henry Hudson sailed some 400 years ago had no power plants on its shores. No trains, bridges, factories or houses. Those innovations changed the river, leaving a legacy of PCBs, sewage and other pollutants. But pollution is just one way that humans have transformed the river. A small way, it turns out.
We may think of the Pacific Northwest as rain-drenched, but new research led by scientists at the University of Pittsburgh shows that the region could be in for longer dry seasons, and is unlikely to see a period as wet as the 20th century any time soon.
