Geotimes January 2007 Kathryn Hansen	Eruptive Event Caught Red-Handed Researchers know that, in general, mid-ocean ridges are the site of periodic eruptive events that create new seafloor. At the East Pacific Rise, determining the seismic characteristics that lead up to eruptions could help researchers predict when and where along the trench future events are likely to occur.
Geotimes January 2007 Carolyn Gramling	Tonga's Newest Island A new island was born in the South Pacific Ocean in August. The surprised crew of the yacht Maiken bore witness to the island's birth during the eruption of a formerly submarine volcano, called Home Reef, that has now breached the ocean's surface.
Geotimes January 2007 Nicole Branan	Heat Flow Causes Magnetic Reversals Earth's magnetic field has done hundreds of somersaults over the last few billion years. A new study sheds some light on what causes the geomagnetic field to flip.
Geotimes January 2007 Margaret Putney	Ice Reveals Polar Temperature Seesaw A new ice core from Antarctica directly correlates abrupt changes in Greenland's climate over the last 150,000 years with counterpart changes in Antarctica -- offering further indication that the two icy regions are connected by ocean currents in a sort of bipolar seesaw.
Geotimes January 2007 Carolyn Gramling	Arctic Not a Refuge for Oil The United States shouldn't lose OPEC's number just yet: The Arctic contains far less undiscovered oil than previously thought, according to a new study.
Geotimes January 2007 Edward Derbyshire	International Collaboration in Global Science: Price or Prize? The UN triennium 2007 - 2009 International Year of Planet Earth aims to contribute to the improvement of everyday life, especially in less-developed countries, and by promoting the societal potential of the world's earth scientists.
Geotimes January 2007 Margaret Anne Baker	Diversity in the Geosciences -- We Can Do Better As minorities become the majority of the population, the inability to tap these communities is a severe handicap to actually tapping the bulk of the best and brightest students and including them in the geoscience community.
Geotimes January 2007 Carolyn Gramling	Max Mayfield: In the Eye of the Storm Max Mayfield has had a busy seven years. Mayfield, who has been the director of NOAA's National Hurricane Center in Miami, Fla. since 2000, has guided the country through some of the busiest hurricane seasons on record, including the record-breaking 2005 season.
Smithsonian January 2007 Dick Teresi	Paleozoic Vermont Peculiar as it may sound, Isle La Motte, which is some 175 miles from the Atlantic Coast, is the best place to see one of the oldest reefs on earth.
Geotimes December 2006 Fred Schwab	Why Fester? Let's Sequester! Instead of looking toward another fossil fuel-based energy choice, scientists need to examine carbon dioxide sequestering, the capture and storage technology that removes anthropogenic carbon dioxide from the atmosphere.
