A team of scientists led by the University of Toronto’s Barbara Sherwood Lollar, Chris Ballentine of Oxford University, and Tulis Onstott at Princeton University, has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth’s surface in rock fractures in Canada, South Africa and Scandinavia. The study, published in "Nature" on December 18, includes data from 19 different mine sites that were explored.
A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth's non-avian dinosaurs, according to new research from Princeton University.
At the start of the 1980s, the question of what forced dinosaurs and huge numbers of other creatures to become extinct 65 million years ago was still a mystery.... “We can now say with confidence,” says Blair Schoene, a Princeton geologist and lead author of the paper, “that the eruptions started 250,000 years before the extinction event, and lasted for a total of 750,000 years.”
Online this week in Science (http://scim.ag/BSchoene), volcanism gets a big boost, and so does one of the most contentious figures in the debate, Princeton University paleontologist Gerta Keller. In the paper, Schoene, Keller, and colleagues report precise dates for the main phase of Deccan volcanism.
Hollister added, in reference to the controversy surrounding planned, postponed and completed seismic studies off the New Jersey coast this past summer, “We monitored marine life very closely (during ACCRETE in 1994) and found no damage had been done.”
Geosciences Professor Michael Oppenheimer talks with PBS Newshour Gwen Ifill about the U.S.-China partnership regarding climate change and what other countries factor into their success.
This December, Hannah Zanowski, a graduate student at Princeton University, will travel to Cape Town, South Africa, bundle up in something warm, and board a German research icebreaker called the Polarstern. Over the next eight weeks, the ship will make its way from the southern tip of Africa to the bottom of South America via the Weddell Sea off the coast of Antarctica, stopping every so often along the way, so Zanowski and the scientists she’ll be working with can plop one of 12 yellow, oblon
What if you have so much to do that you feel overwhelmed and lose motivation? Or if you’ve been working on a project for so long that you begin to lose interest?
The third annual meeting of Princeton E-ffiliates Partnership brought together about 200 academic experts and industry leaders in a day-long discussion of the challenges in creating alternative energy sources, the future of energy investment, and the key areas of energy technology.
Rather than seeking to defend buildings and infrastructure from storm surges, a team of architects and climate scientists is exploring a new vision, with an emphasis on living with rising waters. “Every house will be a waterfront house,” said Princeton Associate Professor of Architecture Paul Lewis. “We’re trying to find a way that canals can work their way through and connect each house, so that kayaks and other small boats are able to navigate through the water.”
