Let’s Discuss Our Water Sources: Impacts of Natural Gas Extraction Along the Upper Delaware

In public debate about the future of America’s energy policy, the Northeast region is in contention regarding gas drilling in the Marcellus Shale field. With this project, we focused on the Marcellus Shale gas extraction along the Upper Delaware, in the Town of Hancock. The process of extraction includes potential environmental hazards and while contentious, is devoid of local oversight. To date, just in Hancock, more than twenty-five percent of the town’s land has been leased for gas drilling.

Norwegian explorer Fridtjof Nansen and British explorer Ernest Shackleton were some of the few who brought their entire crews home safely.

Nansen began his expedition [...]

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 for [...]

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 behave.
In [...]

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 [...]
