Scientists drill nearly 2 miles down to pull 1.2 million-year-old ice core from Antarctic
An international team of scientists say they’ve successfully drilled one of the oldest ice cores yet, penetrating nearly 2 miles to Antarctic bedrock to reach ice that’s at least 1.2 million years old. The project was completed in January by a European-funded project called Beyond EPICA. Analysis of the ancient ice should provide a record of changes in Earth’s atmosphere and climate. And that data may illuminate how glacial and Ice Age cycles have changed, as well as cycles where atmospheric carbon altered Earth’s climate.
