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…

Reaching Out: Educating Specialists and the Public on Earthquake Monitoring
While installing our seismic network in Malawi, we interacted with everyone from scientists to schoolteachers, and journalists to villagers. The opportunity to provide information and education to Malawians has been the most rewarding aspect of our effort. We trained local scientists and technicians on seismic equipment and data analysis, and educated the public on earthquakes…

Haiti Quake Fault Comes Into Focus
Scientists are sailing off the coast of Haiti to assess the recent earthquake there, and the potential for more. This is the latest update, emailed by chief scientist Cecilia McHugh from the research vessel Endeavor. (Read the full story of the project, involving the Earth Institute and other major institutions.) We had a successful day and were able to map…

Shipboard Researchers Image Haiti Earthquake Fault
Scientists are sailing off the coast of Haiti to assess the recent earthquake there, and the potential for more. This is the latest update, emailed by chief scientist Cecilia McHugh from the research vessel Endeavor. (Read the full story of the project, involving the Earth Institute and other major institutions.) Today we surveyed the Baie de Grand Goave, west of…
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
