    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.

Kelly Carroll

Kelly Carroll is a geologist for The Polar Earth Observing Network (POLENET).

Kelly grew up backpacking and hiking in the Appalachian Mountains. Interested in the outdoors, he was curious how the great vistas he was seeing were created. Kelly decided to change from a successful career in the corporate world to pursue an undergraduate degree in environmental geology.

After years with the US Geological Survey, Kelly decided to pursue a graduate degree in hydrogeology at The Ohio State University, where his interest in polar research began. He studied lake ice in Dry Valleys, Antarctica. Then Kelly discovered an interest in teaching and sharing science with the public and decided to change his career from doing science research to educating students and the public about the polar regions.

Kelly has worked for the National Park Service as a park ranger in the largest national park in the United States - Wrangell-St. Elias. His experience with educating visitors on the parks geology and glaciers solidified his interest in polar education.
