Scientists Return from Siberian Drilling Expedition A team of scientists from the United States, Germany,
Russia and Austria has just returned from a 6-month drilling expedition to a
frozen lake in Siberia: Lake El'gygytgyn, which was created 3.6 million years
ago when a meteor hit Earth and formed an 11-mile wide crater. There, from
three holes drilled under the frozen lake, the researchers collected the
longest sediment core samples retrieved in the Arctic region, recovering a
total of 1,165 feet of sediments. The sediment record collected extends back
roughly 2 million years.
Drilling Deep Wells in Downtown Atlanta The Georgia World Congress Center Authority soon will be able to water its green space and turn its fountains back on after a water ban that went into effect October 2007. While water restrictions still are in place, the 200-acre campus no longer will be as much of a strain on the local water supply. Located in the heart of downtown Atlanta, the GWCCA has bored two 660-foot deep wells, which will be used for watering lawns and plants, as well as operating ornamental water features.
