Nearly 20 years after its last eruption, in 1995, Fogo volcano off West Africa awoke on Nov. 26. Within a week, it had buried two villages under scorching lava, leaving 1,200 people homeless. Lamont-Doherty geologist Ricardo Ramalho was there to document the action and help advise local government.
Lamont Doherty Earth Observatory scientists are among the many researchers currently doing fieldwork in Antarctica. They’re participating in expeditions near, above and on the continent, doing critical studies that will advance understanding of Antarctica’s land and sea processes.
Glaciers in one part of West Antarctica are melting at triple the rate of a decade ago and have become the most significant contributor to sea level rise in that region, a new study says. The study found that the glaciers in the Amundsen Sea Embayment of West Antarctica have shrunk by an average of 83 gigatons a year for two decades—the equivalent of the weight of Mount Everest every two years.
The Ross Ice Shelf is the largest of the Antarctic ice shelves, measuring just under the size of the state of Texas. It is several hundred meters thick, although most of this is below the water surface. Along the ~ 600 kilometer front edge of the shelf, the ice towers up to 50 meters in height; a sheer vertical wall of white and the iridescent blue of compressed ice.
The Earth Institute will offer six research assistant opportunities for undergraduate students during the spring 2015 semester. Undergraduates from Columbia and Barnard will be able to serve as research assistants on research projects related to sustainable development and the environment with distinguished faculty and researchers at the cutting edge of this burgeoning field.
While research assistant positions at Columbia are generally awarded to graduate students, this program instead aims to present undergraduates with a unique opportunity to be involved in research at a high level and to gain valuable experience and skills for their future academic and professional careers.
This spring, the Earth Institute is offering Columbia students opportunities to intern within various departments and research centers at the institute. All full-time Columbia and Barnard students are eligible to apply. These internships are funded at a rate of $15 an hour for 10 hours per week and up to a maximum of 120 hours for the spring 2015 semester. The
The Earth Institute will benefit this holiday season from a matching gift from dedicated donor Betsee Parker, who will match your contributions dollar for dollar up to $300,000 this holiday season.
By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.
Migrating south in the winter is a behavior that Antarctic scientists share with many species of birds, although the scientists fly just a bit further south. For the IcePod team it was time to join the migration so they could test their equipment in the most challenging environment the Earth has to offer.
Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th at the American Museum of Natural History Hayden Planetarium, Holtzman and his collaborators will present one of these shows, the second installment of SeismoDome: Sights and Sounds of Global Seismology.
