Researchers at the EGRIP research station have successfully drilled through a 2670-meter ice sheet to reach the bedrock below. This is the first time a deep ice core has been drilled through an ice stream, providing valuable material to analyze. The researchers discovered mud underneath the ice, which has not seen the light of day for roughly a million years. The ice core contains a record of Earth’s climate over the past 120,000 years and will be analyzed in laboratories around the world. The drilling has already delivered exceptional results, changing our understanding of how ice moves and potentially impacting climate models.
