    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

The Center of Operations

The Operations Center is at the center of large field experiments like VOCALS. Here, the scientists plan their aircraft missions. Here is where these plans are passed from the minds of the scientists to the pilots, ground crew and support staff that turn them into reality. Next time you fly on a commercial airliner think about all the people working at the airport and on the plane that have been involved in flying you to your destination. It's a big operation!

The Operations Center is also where discoveries are made. The scientific data from all the various missions are collected here and analyzed by the many scientists involved. Together the scientists form a large human computer whose goal is to make sense of all the data. Only through careful analysis of the data is it clear what these discoveries actually are. It is very difficult to know exactly what new discoveries will be made - in fact, the most exciting thing about discovery is that we don't know what surprises are around the corner.

In the photograph you can everyone here listening to a mission briefing whereby preliminary results from a given flight are presented for the first time to the scientists. The Operations Center is an exciting place to be because there is so much going on, and so much new information to try to make sense of.
