ROME (AP) — Scientists in Antarctica on Wednesday inaugurated the first global repository of mountain ice cores, preserving the history of the Earth’s atmosphere in a frozen vault for future generations to study as global warming melts glaciers around the world.
An ice core is something of an atmospheric time capsule, containing information about the Earth’s past changes in a frozen climate archive. With global glaciers melting at an unprecedented rate, scientists have raced to preserve ice cores for future study before altogether.
The Ice Memory Foundation, a consortium of European research institutes, inaugurated the frozen sanctuary on Wednesday at the Concordia station in the Antarctic Plateau. The foundation livestreamed the ceremonial ribbon cutting and opening of the frozen cave where the ice samples will be kept for future generations.
The first two sets of samples of Alpine mountain ice cores were drilled out of Mont Blanc in France and Grand Combin in Switzerland and arrived at the station after a 50-day refrigerated icebreaker and plane journey from Trieste, Italy.
During the inauguration ceremony, pairs of foundation team members brought box after box of ice cores into the cave, burrowed deep into a 5-meter (yard) high compacted snow drift at a constant temperature of around -52°C/-61°F.
“By safeguarding physical samples of atmospheric gases, aerosols, pollutants and dust trapped in ice layers, the Ice Memory Foundation ensures that future generations of researchers will be able to study past climate conditions using technologies that may not yet exist,” said Carlo Barbante, vice chair of the Ice Memory Foundation and a professor at Ca’ Foscari University in Venice.
The Ice Memory project was launched in 2015 by a consortium of research institutes: From France, the ɫtv Centre for Scientific Research (CNRS), the French ɫtv Research Institute for Sustainable Development (IRD) and the University of Grenoble-Alpes; from Italy the ɫtv Council of Research (CNR) and the Ca’ Foscari University in Venice, and Switzerland’s Paul Scherrer Institute.
Scientists have already identified and drilled ice cores at 10 glacier sites worldwide and plan to transport them to the cave sanctuary for safekeeping in the coming years. The aim over the coming decade is to craft an international convention to preserve and safeguard the samples for future generations to study.
As temperatures globally rise, glaciers are , and with them critical information about the atmosphere: Since 2000, glaciers have lost between 2% and 39% of their ice regionally and about 5% globally, the foundation said.
“These ice cores are not relics … they are reference points,” said Celeste Saulo, secretary-general of the U.N. World Meteorological Organisation. “They allow scientists now and in the future to understand what changed, how fast and why.”
