Kartik Chandran, an environmental engineer at Columbia, will discuss some of his urban wastewater treatment projects at a panel discussion Friday following the screening of a new film about Rio de Janeiro’s Guanabara Bay.
If U.S. sulfur dioxide emissions are cut to zero by 2100, as some researchers have projected they will be, rainfall over Africa’s Sahel region could increase up to 10 percent from 2000 levels, computer simulations suggest.
The sheer number of observations now streaming from land, sea, air and space has outpaced the ability of most computers to process it. The Data Science Institute’s newest working group —Frontiers in Computing Systems—will try to address some of the bottlenecks facing scientists working with these and other massive data sets.
Researchers at Lamont-Doherty Earth Observatory have published a new study showing that a tsunami of unimaginable size swept over the Cape Verde Islands some 73,000 years ago. The discovery may have implications for the potential for modern hazards. READ THE FULL SCIENTIFIC STORY
The Big City, Subdivided for Sustainability
Two-thirds of people on the planet will live in cities by 2050. But few cities are prepared for this population boom. An upcoming research project will explore new, localized models for urban infrastructure to make cities cleaner, healthier and more enjoyable places to live.
Computer scientists at Columbia University will work with oceanographers to understand what has caused an unusual plankton-like species to rapidly invade the Arabian Sea food chain, threatening fisheries that sustain more than 100 million people.
Two women investigating climate change from different perspectives—Christine McCarthy, a geophysicist at Lamont-Doherty Earth Observatory, and Denise Iris, a multimedia artist from Brooklyn—had a chance to spend several days together recently. In the Rock Mechanics Lab at Lamont, where McCarthy works, and a nearby “cold room” chilled to the climate of an industrial freezer, they exchanged notes on two ways of looking at ice.
A team of scientists traveled to the Pacific Northwest aboard the R/V Atlantis last fall to investigate whether the waxing and waning of ice ages and volcanic eruptions are somehow related.
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.
Once a year, Piermont Pier becomes a field station, and local students, a team of environmental investigators. On Tuesday, scientists at Lamont-Doherty Earth Observatory led students through a series of field experiments designed to teach them more about the Hudson River.
