PUNTA ARENAS, Chile–Not all rides in the DC-8 are smooth and effortless. Our flight down the Thwaites Glacier was a race against weather, with the stomach-churning quality of a carnival ride. Both the Thwaites and Pine Island glaciers flow into the Amundsen Sea. This section of Antarctica, along [...]

PUNTA ARENAS, Chile–Skimming across the Weddell Sea at 250 miles per hour I am finally on the way to Antarctica. Even though my visit to the white continent will be at a height of 1500 ft I still feel a sense of ‘homecoming’, as if I am back [...]

PUNTA ARENAS, Chile–After flying for several hours over a windswept Southern Ocean, the mission director announces that we will be slowly descending towards Antarctica’s Pine Island Glacier. Just below are the Hudson Mountains, a small group of extinct volcanoes poking through the ice.
As we approach our survey area, John Sonntag from NASA’s flight facility on [...]

Nick Frearson, Gravimeter Instrument Team, Lamont-Doherty Earth Observatory:
PUNTA ARENAS, Chile–I have become a night watchman of sorts. The gravimeter we’re using in our flights over Antarctica must remain powered at all times, so between flights I hole up in the old terminal next to the aircraft watching, …and watching. We won’t be on the first [...]

Before airplanes and satellite phones, polar exploration was a more dangerous undertaking than it is now. Many who set out for the frozen ends of the earth did not come back. Norwegian explorer Fridtjof Nansen and British explorer Ernest Shackleton were some of the few who brought their entire crews home safely.

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 [...]

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 [...]

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 alike. Now a new group is finding inspiration: artists.
