As climate change imperils glaciers, scientists are scrambling to build a library of ice archives. Ice stores climate data from the past, but if it melts, that valuable information could be lost. A project called Protecting Ice Memory aims to extract ice from the Illimani Mountain in Bolivia and preserve it in Antarctica.
The Illimani glacier’s ice can help scientists reconstruct 18,000 years of records. Rising temperatures – especially in the wake of the last El Niño – endanger that data, so in May, a team plans to scale the mountain to obtain three cores, two of which will be sent to a cave at the Concordia Research Station in Antarctica, where annual temperatures are currently around negative 65.2 degrees Fahrenheit. Even if temperatures warm a few degrees, the samples should be safe in this natural freezer.
It won’t be easy. The Illimani glacier is almost four miles above sea level. The summit isn’t accessible by helicopter, so the scientists must go up on foot. The team will camp partway up Illimani for a few weeks to acclimatize. Then local porters will tote their 4,500 pounds of equipment to the summit, and it will take another few weeks to install all that equipment. It will take two to four days to extract each one of the three ice cores. Then they’ll need to walk back down the mountain to ship the samples out – two to Antarctica and one to France to study.
Patrick Ginot, a Protecting Ice Memory leader, told Fast Co.Exist, “We’re really close to losing the site. It’s really an emergency to extract the ice cores before another warm event will happen…The logistics are complicated to bring it to South Antarctica, but once it’s there, it’s safe.”
Protecting Ice Memory has already gathered ice from the Col du Dôme glacier in the Alps’ Mount Blanc. The researchers will collaborate with an international team to obtain ice cores from other locations around the world and develop a library of ice archives possessing dozens of samples for future researchers.
