The Isthmus of Panama: Out of the Deep Earth

Geologists are investigating igneous rocks from the deep earth that helped build the land bridge that joins North and South America. These are most visible along the windswept western coast of Panama. CLICK TO SEE A SLIDESHOW OF THE WORK

The creation of the narrow isthmus that joins North and South America changed not just the world map, but the circulation of oceans, the course of biologic evolution, and probably global climate. Scientists try to decipher the story behind its formation.

The formation of the slender land bridge that joins South America and North America was a pivotal event in earth’s history. At its narrowest along the isthmus of Panama, it changed not just the world map, but the circulation of oceans, the course of biologic evolution, and global climate. Cornelia Class, a geochemist at Columbia University’s Lamont-Doherty Earth Observatory, and Esteban Gazel, a Lamont adjunct researcher now based at Virginia Tech, are looking into a key factor: the Galápagos Plume.

Helping Consumers See the Green Behind Fuel Economy

New research from the Center for Research on Environmental Decisions sheds light on how best to present information on U.S. fuel economy labels. Consumers choose fuel-efficient vehicles more frequently when fuel economy is expressed in terms of the cost of gas on a long term, 100,000-mile scale. The scale currently used on the U.S. fuel economy label (15,000 miles per year) produced the weakest preference for fuel-efficient vehicles in this study.

As the arctic region loses ice in a changing climate, the economic and social tradeoffs are unclear. How will we balance economic, social and environmental functions? The Center on Global Energy Policy and the Consulate General of Canada in New York will examine these questions in a discussion on March 26: “Understanding the Arctic Resource Challenge: Canada and U.S. Perspectives.”

Columbia University's Executive Vice President for Research, Michael Purdy, addresses the audience at Lamont-Doherty's Ultra Clean Laboratory dedication.

In late 2013, the dream of creating a uniquely powerful facility for the Lamont-Doherty Geochemistry Division became a reality upon completion of the Comer Building’s Ultra Clean Laboratory. On the afternoon of November 20th, this new laboratory was dedicated in front of an audience of Observatory Advisory Board members, donors, scientists and other members of the extended Lamont-Doherty and Columbia University communities.
