Thinking on Your Feet on the Ice
Nick Frearson, Gravimeter Instrument Team, Lamont-Doherty Earth Observatory: I’m a senior engineer at Columbia University’s Lamont Doherty Earth Observatory, and my role in Operation Ice Bridge is to work with the gravimeter. This instrument can see beneath ice sheets into the water and bedrock below to reveal the ice sheet’s hidden contours – critical information…

A New Way to Experience Antarctica
Michael Studinger, Instrument Co-Principal Investigator, Lamont-Doherty Earth Observatory: The scale and style of Operation Ice Bridge will be a new experience for me. I’ve been involved in airborne research for more than a decade using ice-penetrating radar systems, airborne laser scanning, gravity and magnetics to learn more about the polar ice caps and how they…

Shaking Out Some Money
That rumbling you feel is not necessarily a passing subway. New York City and the surrounding region gets a surprising number of small earthquakes, and a 2008 study from the region’s network of seismographs, run by Lamont-Doherty Earth Observatory, suggests that the risk of a damaging one is not negligible. This week, the federal government announced a major upgrade…

Turning CO2 Into Stone
A power plant in Iceland is set to become the first in the world to try turning carbon dioxide emissions into solid minerals underground, starting this September.

Down by the River, Running Out of Water
Too little water for too many people is a growing problem in poor countries–and in thriving suburban Rockland County, N.Y., just north of New York City. A new website, Water Resources in Rockland County, lays out the case, and neatly puts it into global context. The site is run by the Earth Institute’s Center for International Earth Science Information Network…

Pondering the Deep
Another world lies beneath the Hudson River, as scientists have shown using pulses of sound to map the bottom. In recent years, the bathymetry maps developed at Lamont-Doherty Earth Observatory and Stony Brook University have turned up hundreds of shipwrecks and a new channel off Battery Park City, drawing interest from treasure hunters and mariners…

The Heat is On: Can Mass Transit Adapt?
Even on a sunny day, nearly 13 million gallons of water are pumped from New York City subways. As global warming brings rising sea levels and stormier weather, more flooding is expected for New York’s transit system. To adapt, the Metropolitan Transportation Authority needs to develop a master plan that lays out the costs of…

Arsenic in Bangladesh Water, Then and Now
Back in the summer of 1997 while working for a small newspaper focusing on UN development issues, I traveled to Bangladesh to see how far this often overlooked country tucked away in a corner between India and China had fared since its independence 25 years ago. At the time the only stories which came out…
