  • Some Thoughts About Dust, Rio Gallegos

    I’ve been to Stewart Island, off the southern tip of New Zealand, but I’m pretty sure this is the furthest south I’ve been. Cool! We’re here in Rio Gallegos. We’ve just rendezvoused with Dr. Jay Quade, a geologist from the University of Arizona, and his wife Barbara. We’ve got two cars, a bunch of boxes…

  • Assessing Continuing Quake Risks, by Sea

    This week U.S. and Haitian scientists will start a 20-day research cruise off Haiti to address urgent questions about the workings of the great Jan. 12 earthquake, and the possibility of continuing threats. They hope to gather sonar images, sediments and other evidence from the seafloor that might reveal hidden structures, how they have moved,…

  • Arrival: Buenos Aires

    We arrived in Argentina after a night in the air—maybe the first time I’ve ever gotten a (nearly) decent night’s sleep on a plane. We took a taxi across the city. It’s hot and flat, and our taxi driver explains that they’ve had torrential rains for several weeks; all the lowlands alongside the highway are…

  • Scientists Sail to Assess Haiti Quake Threat

    Research Ship Will Image Faults, Seek Signs of Hidden Dangers

  • Following the Trail of Ancient Icebergs

    A few days ago we reached our main study area in the eastern Amundsen Sea. Here we are using sonar to map the contours of the seafloor in great detail. During the last glaciation the Antarctic ice sheet was much larger and covered most of the continental shelf, an underwater extension of the continent that…

  • Climate, Fires and Birds: How is the Tundra Changing?

    Natalie Boelman is an ecologist at Lamont-Doherty Earth Observatory who studies the effects of climate change on organisms throughout the food chain. She first visited the Alaskan Arctic in 2001, and will return to the North Slope this spring and summer to continue a wildfire-mapping project and to set up a field study that will…

  • A Video Camera on the Bottom of the Ocean

    Here is a video montage showing highlights of the seafloor deployment of the VentCam (created by Carl Robinson): You can read more about this project here, and more on the deployment of this particular instrument here.

  • Jaunt to Nearby Island Becomes Four-Day Epic

    Going to Antarctica involves a whole lot of paperwork. Before I left, I filled out an extensive medical history, was tested for every disease imaginable, gave my pants size, shoe size, hat size, until I had only one form remaining. That was the waiver acknowledging that working in Antarctica is inherently dangerous and that by…

  • So Much Depends on Sea Ice

    Where we work and how we get there depends on the sea ice. The Oden is a powerful icebreaker but it is often faster and more fuel-efficient to go around heavy sea ice then to chop our way through. If the sea ice is several feet thick, we often choose to detour. We actually consult…

Composite banner with modern building at night and portrait of Dean Alexis Abramson that reads "Science for the Planet"

By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
