Abstract
An international team of researchers recently drilled 2,037 m to bedrock in the Greenland Ice Sheet and extracted the longest ice core ever retrieved in the arctic region, according to information from the National Science Foundation. The core, from a site called Dye 3 in southeastern Greenland, will enable scientists to learn more about the climates and environments that existed during the past 100,000 years. The cores will be examined for traces of repetitive climate cycles; from these studies, projections may be made on future climate.The Dye 3 drilling project is the second one in which bedrock was reached in Greenland. In 1966, a 1,387 m core was extracted at the Camp Century site in northwestern Greenland. A longer core (2,164 m) was obtained in Antarctica at Byrd Station.
