6/20/2008 10:21 Parts of a rare mummified dinosaur that has attracted worldwide interest went on display in North Dakota's state museum.

4/9/2008 14:25 John Wettlaufer appointed the Alan M. Bateman Professor.

4/9/2008 14:22 Shun-ichiro Karato named the Adolph Knopf Professor

4/9/2008 14:01 Plate Tectonics and Supercontinents on Early Earth? A Paleomagnetic Study
The rich Earth history that has thus far been discovered hails predominantly from the Phanerozoic Eon, the ca. 540 million years since the explosion of the scrutinized fossil record. The preceding Proterozoic Eon is 1900 million years long yet relatively untouched. In the Proterozoic, only paleomagnetic data can provide quantitative constraints on the paleogeography of ancient continents and their more ancient building blocks, 'cratons'. Sampling ancient lavas for their paleomagnetic directions, Ross plans to investigate two large questions about global evolution about 2 billion years ago: (1)was plate tectonics an active process on Earth already?, and (2) did the early cratons collide at different times to form several separate "supercratons" or did they form one, long-lived, and globe-girdling supercontinent? He and his advisor David Evans have selected field sites on the Wyoming craton (WY and MT) and the Slave craton (Northwest Territories of Canada): the last remaining puzzle pieces to place in hopes of documenting the making of the North American continent.

4/1/2008 12:15 NSF grant for a new instrument upgrade to the Electron-Microprobe-Analysis Laboratory
The department has been awarded an NSF (IF/EAR-0744154) grant for a new instrument upgrade to the electron-microprobe-analysis (aka EMPA or EPMA) laboratory. This award was facilitated by very generous matching funds from Yale University. An order has now been submitted for the JEOL JXA-8500F (field-emission-gun=FEG) "Hyperprobe". This machine will permit imaging of nanometerscale features and analytical (chemical) resolution of features perhaps as small as 200nm. This analytical resolution applies to both quantitative analysis and extremely high-resolution chemical mapping. For more information on the microprobe lab, including SEM capabilities, please visit http://earth.geology.yale.edu/~joe2/microprobe.html.

4/1/2008 11:49 Yale geophysicist was awarded the Microsoft A. Richard Newton Breakthrough Research Award
Prof. Jun Korenaga was awarded for his proposal entitled "How to build a habitable planet: Estimating the physics of plate-tectonic convection on Earth". He is one of ten winners of Microsoft's newly created award program.

03-25-2008 03:32 PM Air Temperatures Above the Earth's Surface
Yale researchers have created a new dataset tracking air temperatures above the Earth's surface over recent decades. Corrections applied by an advanced method reveal that the middle and upper troposphere (3-14 km altitude) have been warming faster than indicated by uncorrected datasets.

3/20/2008 15:16 Dot Earth: Back to 1988 on CO2, Says NASA's Hansen
Andrew C. Revkin: NASA's James Hansen makes case for returning CO2 levels to those of 1988.

3/18/2008 15:06 Mummified dinosaur unearthed in North Dakota…
Scientists on Monday announced the discovery of what appears to be the world's most intact dinosaur mummy: a 67-million-year-old plant-eater that contains fossilized bones and skin tissue, and possibly muscle and organs.

2/15/2008 10:08 Mini Lake Vostok yields clues to ancient life.
A miniture model of the world's largest subglacial lake, Antarctica's Lake Vostok, has given clues to the way its waters circulate, and hence on where scientists should drill to find life....

2/7/2008 13:52 Wildt Lecture - Karl Turekian (Host), Feb. 14, 2-3:30pm, KGL 123

2/7/2008 13:49 Weekly Colloquium: Bernard Hallet, University of Washington: Title TBA, Feb. 13, 4-5pm, KGL 123.

2/7/2008 13:45 Topics in Global Change-Larry Edwards, University of Minnesota "How to Terminate a Glacial Period: Constraints from Cave Climate Records", Feb. 11, 2-3pm, KGL 102

10/9/2007 15:47 Assistant Professor Alexey Fedorov is the 2007 recipient of the highly prestigious David & Lucille Packard Foundation Fellowship for Science & Engineering.
Professor Fedorov studies climate dynamics and ocean circulation and, in particular, ocean-climate coupling. His recent ground-breaking work on the triggering of a permanent El Nino during global warming events has received wide attention, including a recent paper in the Journal SCIENCE.

7/3/2007 9:52 Icy Stars Reveal The Secret Of Their Patterns: Physicists Venture Onto Thin Ice (Wettlaufer, J.)

7/3/2007 9:49 Is Nitrogen Pollution Changing the Food Chain in Long Island Sound? (Thomas, E.)

5/1/2007 13:40 An Earth-Day write up on research on the effects of eutrophication and global warming on Long Island Sound.

4/9/2007 11:25 Houghton Lectures at MIT

4/9/2007 11:22 Greenhouse Gas Effect Consistent Over 420 Million Years

3/1/2007 16:26 COLD FINGERS: For more than half a century, scientists and polar explorers have puzzled over the origin of serrated zipper-like patterns that sometimes form when floating ice sheets collide.
In the 23 February Physical Review Letters, physicists give the first theoretical explanation for these formations. The same mechanism may have a role in shaping the boundaries of tectonic plates, the researchers suggest, and might be used to create structures as small as the gears of a nanomachine. (Dominic Vella and J.S. Wettlaufer, Phys. Rev. Lett. 98 088303)
