Paul Richards Wins Seismological Society of America’s Reid Medal
In a research career spanning more than four decades, Paul Richards, a seismologist at Lamont-Doherty Earth Observatory, has helped uncover Earth’s inner structure and advanced techniques for detecting nuclear explosions to ensure that bans on nuclear testing can be enforced. Richards will receive the Seismological Society of America’s Harry Fielding Reid medal at its annual…

Weather is Still the Master Here
It’s amazing to think that Greenland is only hours from Baltimore’s BWI Airport, but the aircraft loaded at 2AM and we arrived in Greenland six hours later at 8 AM local time. The science teams are transported on an Air Mobility Command flight, the US Military’s “airline” for service men and women, contractors, and others…

New Book Explores Link Between Climate and Ocean Currents
Wallace Broecker is a climate scientist at Lamont-Doherty Earth Observatory who has helped shape our understanding of how the ocean moves heat around the globe, and how this so-called “great ocean conveyor” can switch the climate to a radically different state. Many scientists used to think that only periodic changes in earth’s orbit—so-called Milankovitch cycles–…

Dog sled races link back to a centuries old tradition
One of the events that Thule looks forward to hosting each year is Armed Forces Day. The festival attracts several hundred people, both Inuit families and Air Force personnel. Held on the ice of North Star Bay, the events include broomstick hockey, snowmobile rides, helicopter rides, children’s craft activities and dog sled races. The dog…

The weight of ice
Taking off amidst snow flurries we are headed completely across the Greenland ice cap to the northeast corner of of the country. This flight will differ from most of the DC-8 flights during the Ice Bridge 2010 Greenland campaign. The DC-8 flights are mainly used to measure sea ice or surface mapping with high altitude…

Ice Cube Science
We have flown three flights in the last week, with a fourth postponed as winds were too high for take off. Two of the flights have focused on sea ice in the Arctic. The first was flown north of Canada’s Ellsmere Island, where thick multiyear ice tends to accumulate. We examined the thickness of that…

Following Arctic Leads
Our ICE Bridge team of 34 scientists and NASA personnel has piled mounds of equipment, luggage, and emergency Arctic survival gear into the DC-8, setting off just before midnight for Thule, Greenland.All but two of the seats are filled, and every possible open area has been piled with our supplies for the next few weeks.Our…

California ‘shake down’ starts Greenland trip!
Jim Cochran, Geophysicist, Lamont-Doherty Earth Observatory ICE Bridge scientists gathering at NASA’s Dryden Flight Research Center (DFRC) in Palmdale, CA for our upcoming Greenland mission were greeted in true California style. We were awakened by a magnitude 4.4 earthquake in the middle of the night! Although small by California standards the event was centered only about…

Initiatives to Help Haiti Recover
A new set of web pages describes the Earth Institute’s wide-ranging involvement in helping bring relief to quake-battered Haiti, as well as plans for long-term recovery, and associated environmental and economic issues. One major program, the Haiti Regeneration Initiative involves the Center for International Earth Science Information Network (CIESIN), Center for Research on Environmental Decisions, Tropical Agriculture…
