Record-breaking Antarctic drill reveals 23 million years of climate history
An international team featuring faculty at Binghamton University, State University of New York has drilled the longest ever sediment core from under an ice sheet, providing a record stretching back millions of years that will help climate scientists forecast the fate of the ice sheet in our warming world.
It is the longest climate archive that experts have ever recovered under an Antarctic ice sheet. The sediments could go back 23 million years to the past.
Subglacial data: An international research team has drilled the longest sediment core from the Antarctic subsoil. The 228-metre-long core from the edge of the Ross Sea contains sediment layers that date back up to 23 million years. This can reveal how Westantarktis' ice reacted to past heat periods – and when an unstoppable defrosting of this ice sheet threatens. Initial investigations show that there were actually ice-free phases. How does the …
What does the 23‑million‑year Antarctic core show?
A continuous climate record from beneath the ice An international drilling campaign has recovered the longest sediment core taken from beneath an ice sheet, opening a 23‑million‑year window into Earth’s polar climate. The sediments stack up as a layered archive: changes in grain size, chemistry…
How does the sensitive ice of the West Antarctic react to elevated temperatures? Is there an irreversible ice melt? Answers to these questions could now be provided by a 228 metre long sediment core from the West Antarctic. It is the longest and most distant core from this region. An international team has won it at the transition of the Ross Ice Shelf to the West Antarctic Ice Sheet [...] The article West Antarctica: Research team wins the long…
