Geotimes February 2004 Sara Pratt	Volcanic forcing of El Ninos Research has begun to connect large volcanic eruptions with the onset of an El Nino. Now, climatologist Julian B. Adams of the University of Virginia and colleagues report in the Nov. 20 Nature that the events are likely linked in certain cases.
Geotimes February 2004 Naomi Lubick	Microplates under the Aegean Researchers have gathered together a broad network of GPS data to draw a map of microplates in the Aegean. The data fit a simpler model than expected, and the results, they say, imply that larger continental plates may be composed of microplates too.
Geotimes February 2004 Sara Pratt	Fire cooks rock clocks A new field study has confirmed what models had previously predicted: The intense heat of wildfires can reset the helium "clock" in rocks, making them appear younger than they are.
Geotimes February 2004 Megan Sever	Mesopotamian climate change At the American Geophysical Union annual meeting in December, one archaeologist presented research that suggests that climate change affected the way cultures developed and collapsed in the cradle of civilization -- ancient Mesopotamia -- more than 8,000 years ago.
Geotimes February 2004 Naomi Lubick	Triggering Tsunamis A controversy over whether an earthquake or an underwater landslide generated the 1998 Papua New Guinea tsunami rekindled interest in such events; it also drew geologists into a field that had been dominated by modelers and seismologists.
Geotimes February 2004 Edward C. Roy Jr.	Assessing Earth Science in Texas In Texas, a group of geoscientists is fighting to restore earth science to the core curriculum of the state's high schools.
Geotimes February 2004 David Applegate	Grand Plan for Another World NASA's new mission to the Moon and Mars could have significant implications for its mission here on Earth.
Geotimes February 2004 Naomi Lubick	Don Turcotte: From convection to chaos Don Turcotte was awarded the American Geophysical Union's Bowie Medal last December, its highest honor. Turcotte reflects on his path from aerospace engineering to geophysics.
Geotimes February 2004 William E. Brooks	Coal and Cremation in Ancient Peru Geochemical data are revealing a potential new role for coal in pre-Colombian Peru.
Geotimes February 2004 Julie Brigham-Grette	One If by Land, Two If by Sea A review of Lost World: Rewriting Prehistory -- How New Science is Tracing America's Ice Age Mariners by Tom Koppel
