One of the earth’s newest islands exploded into view from the bottom of the southwest Pacific Ocean in January 2015, and scientists sailing around the volcano this spring have created a detailed map of its topography.
Maureen Raymo, a marine geologist at Lamont-Doherty Earth Observatory whose name is connected with key theories about how ice ages wax and wane and how sea levels change, has been elected to the National Academy of Sciences, one of the highest honors awarded to scientists in the United States.
In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.
Natalie Boelman and colleagues are tagging American robins near Slave Lake, Alberta, Canada, as the birds migrate north to nesting grounds. In a recent blog post for NASA, she put up videos about their work. You can watch some of them below, or go to the blog page at NASA’s Earth Observatory to see and read more.
Elke Weber, who studies how people make decisions and how they think about climate change, and Terry Plank, who probes deep into the Earth’s interior to study magma and how volcanoes erupt, are among the members elected to the American Academy of Arts and Science this year.
“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing of the separation of the continents.”
Climate scientists teamed up with an econometrics expert to develop an innovative new method for picking out past volcanic eruptions in temperature reconstructions going back millennia and gauging their impact on the climate.
For his pioneering work in rock mechanics and his skill at communicating earthquake science, Scholz is being honored on April 20 by the Seismological Society of America with its top award, the Harry Fielding Reid Medal.
Vicki Ferrini has spent a lot of time working on mapping the ocean floor, and now she’s sailing in the South Pacific to get a closer look.
Ecologist Natalie Boelman is headed back to the far north to study birds—this time to the town of Slave Lake, in northern Alberta, Canada, to track the migration of American robins. She will have some schoolchildren in New York remotely helping her as she and her colleagues get to work.
Two decades after arsenic was found to be contaminating drinking water across Bangladesh, tens of millions of people are still exposed to the deadly chemical. Now a new report from the group Human Rights Watch charges that the Bangladesh government “is failing to adequately respond” to the issue, and that political favoritism and neglect have corrupted the government’s efforts.
This summer, 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.
Science at sea isn't easy, but the benefits are huge, writes Sidney Hemming in her final post from a two-month expedition that collected millions of years of climate history in the deep-sea sediment from off southern Africa.
Expedition 361's newest sediment cores brought up spectacular foraminifera—translucent, glassy and “very pretty” throughout the ocean sediment.
Sidney Hemming and her team aboard the JOIDES Resolution got a surprise when they began taking sediment cores from their first river site off southern Africa—about 10 times more sediment than expected.
