Researcher finds key to ancient weather patterns in Florida's caves
Date:12/6/2011

ll record for North Florida. In a unique arrangement with the Southeastern Cave Conservancy Inc. (SCCI), a nonprofit group that owns dozens of caves in the southeastern United States, he was allowed to take the stalagmites as long as he made duplicates of them and placed the duplicates back in the cave a measure of cave conservation.

The real stalagmites will be studied at the National High Magnetic Field Laboratory (http://www.magnet.fsu.edu/) at Florida State, where Tremaine, a graduate research assistant, is currently stationed in the geochemistry lab.

So far, Tremaine has been scrutinizing carbon, oxygen and strontium isotopes on modern calcite grown in the cave on glass microscope slides what he calls "modern calibrations of ancient proxies." Isotopes of an element are atoms with the same number of protons but different number of neutrons, thus a slightly different atomic mass. He will use that data to get a better idea of ancient ventilation patterns, the temperature inside of a cave when the stalagmites were forming, what type of vegetation was growing above the cave, of, and whether the weather was cold, warm or hot during a particular span of time.

"By looking at trace elements we can get an idea of very wet and very dry rainfall patterns and cycles," Tremaine said. "We'll better understand severe weather patterns."

Tremaine, along with a six-member team of scientists, researchers and graduate students, will cut the stalagmites in half and then use a 50-micron laser to vaporize calcite that they will then measure with a spectrometer. The laser will allow them to study monthly weather patterns in the Northern Gulf Region thousands of years ago. By extracting calcite powders with a half-millimeter drill bit, they will examine the region's wet and dry seasons in five-year increments. Eventually, they hope to create a high-resolution time series, analyzing monthly weather patterns ov
