Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements
On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light.
Fieldwork is exciting and inspiring, leading scientists to new ideas, places and observations about how the world works. Spring on Alaska’s North Slope provides an especially productive environment for fieldwork. When the sun never sets, it’s easy to linger in the field and the lab long into the well-lit night.
While I arrived in Barrow, Alaska on Tuesday, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack, and graduate student Kyle Kinzler from Arizona State University, got here one week ago.
Each fall the Earth Institute offers a unique insight into the cutting-edge research of institute centers and units and the policy implications of that research in the Earth Institute Practicum. The practicum provides an opportunity to learn about issues in sustainable development, sustainability management and environmental science from faculty and researchers in these areas.
“Thank you for coming on this gorgeous day, to sit in an airless, lightless room and discuss how to save the world,” said John Mutter, director of Columbia’s PhD in Sustainable Development and a member of the Earth Institute faculty, in welcoming the audience of the Sustainable Development Seminar, “The Population Bomb: Defused or Still Ticking?” The seminar brought together a panel of demography and population experts, who, Mutter calculated, shared a total of 121 years’ experience in the field. It became apparent, upon the beginning of the discussion, that the population bomb was not so much ticking, as exploding. The current world population, which is estimated to be 7 billion, is projected to reach 10.2 billion by 2100.
On March 1st, 2011, CERC will host Sustaining Life, Securing Our Future, a day-long symposium that brings together leaders in biodiversity research, conservation, and education to present on the extraordinary diversity of the natural world and its role in securing a sustainable future. CERC will be tweeting live information as the conference unfolds!
Watch a short video about the research of Lamont-Doherty geochemists and learn how you can support it. Researchers from the Earth Institute’s Lamont-Doherty Earth Observatory study the planet’s dynamic earth processes by venturing to the source, whether it be the submerged mountains of the Antarctic, the volcanoes of Southern Italy, or the stalagmite-rich caves of [...]
A new multimillion dollar research program by the Consultative Group on International Agricultural Research aims to alleviate climate-related threats to the food security, livelihoods and environment of people living in the developing world. One of the key intellectual forces behind this initiative has been the IRI‘s Jim Hansen. He’ll be leading efforts within the program [...]
Landslides kill thousands of people each year but because they’re often triggered by earthquakes or heavy rains, the danger remains poorly understood. “In densely populated areas, landslides take no prisoners,” said Art Lerner-Lam, a scientist at Columbia University’s Lamont-Doherty Earth Observatory. “They’ll wipe out an entire village at once. Even a small landslide can kill [...]
