Alpine ice – no more than a memory? New archive of ice cores
Alpine glacier – endangered species? (Pic: I.Quaile)
It was with mixed feelings that I read an article drawn to my attention by a colleague earlier in the week.
“Protecting Ice Memory” is the subject –a description of a new project to create a “global archive of glacial ice for future generations”.
I am generally enthusiastic about all projects concerning ice. The worrying thing is the reason why this project has been deemed necessary.
“The goal is to build the world’s first library of ice archives extracted from glaciers which are threatened by global warming”. There we have it. Another frightening acknowledgement of the extent and speed of global change.
How sad that our human-induced warming is threatening our ice, especially here in the European Alps, where we do not have as much ice as in some other parts of the globe. How good that we have the technology to save some of it for posterity. How frustrating that while we also have the technology to shift to a zero-carbon economy and stop the ice melting, we are not actually doing it anything like fast enough.
Starting on Monday August 15th and carrying on until early September, an international team of glaciologists and engineers (French, Italian, Russian and American) will be travelling to Mont Blanc, in particular to the “Col du Dome” glacier area, which is 4,300 metres or 14,108 feet up. They will be drilling the first ice cores for the “Protecting Ice Memory” project.
Saving the cores
The team will be coordinated by Patrick Ginot from the French Research Institute for Development (IRD), working within the UGA-CNRS Laboratory of Glaciology and Environmental Geophysics (LGGE), and Jerome Chappelaz, director of Research at the CMRS and working within ths same laboratory.
The team will be extracting three ice cores each 130 metres long. These will be taken down by helicopter and taken to the LGGE in Grenoble. Clearly they will have to kept very cold during the process.
In 2019 (why only then, I wonder?), one core will be analysed to start a database which is ultimately to be made available to the whole world scientific community.
The other two will be transported by ship to ANTARCTICA. Yes, you read correctly. There, they will be taken on tracked vehicles across the high plateaus to be stored at the Concordia station, which is run by the French Paul-Emile-Victor Polar Institute (IPEV) and its Italian partner, the National Antarctic Research Programme (PNRA)
In the long term, dozens of ice cores are to be stored in a snow cave at -54° Celsius, which the project describes as “the most reliable and natural freezer in the world”.
The Mont Blanc glacier is the first step. The next will be carried out in 2017 on the Illimani glacier in the Bolivian Andes.
It seems other countries with access to glaciers are also hoping to join the project, including Germany, Austria, Switzerland, Brazil, the USA, Russia, China, Nepal and Canada. That sounds like a real mega-project.
I have commented often enough here on the Ice Blog on the dwindling ice in my own favourite hiking territory in the German and Swiss Alps. Last week it was the turn of the New Zealand Alps to be the focus of this rather sadly motivated attention.
The scientists who came up with the project had the idea after observing a rise in temperatures on several glaciers. At ten year intervals, they say the temperature near the glaciers on the Col du Dome and Illimani in the Andes has risen between 1.5 degrees and 2 degrees (Those figures sound familiar from somewhere…)
“At the current rate, we are forecasting that their surface will undergo systematic melting over the summer in the next few years and decades. Due to this melting and the percolation of meltwater through the underlying layers of snow, these are unique pages in the history of our environment which will be lost forever”, says the project description.
The scientists compare their project to the Svalbard Global Seed Vault on the Norwegian Arctic island of Spitsbergen. Before I read that part, this very comparison had already come to my mind. I had a rare opportunity to visit that vault a couple of years ago.
Svalbard to Antarctica
But one of the very worrying things in that connection is that even that “secure coldspot” has in turn been affected by permafrost melt – at least at a level close to the surface, which caused damage to the entrance area in the early stages.
Will the Svalbard vault ultimately have to be moved to the even colder Antarctic at some point in the future, one might wonder?
I remember a visit to the Alfred-Wegener Institute in Bremerhaven, Germany’s polar agency. One of the highlights was a look into the laboratory where ice cores are processed. Clearly, these provide invaluable evidence of how our planet and life on it have developed. Climate and environmental archives of a quite unique nature.
“Our generation of scientists, which bears witness to global warming, has a particular responsibility to future generations. That is why we will be donating these ice samples from the world’s most fragile glaciers to the scientific community of the decades and centuries to come, when these glaciers will have disappeared or lost their data quality”, says Carlo Barbante, the Italian project initiator and Director of the Instutite for the Dynamics of Environmental Processes – CNS, Ca’Foscari University of Venice”. What a sobering thought – and a daunting task.
And what an inspiring campaign to rescue what it seems we will not be able to save in time in the natural world.
Projects like this cost a lot of money. It is relying on private sponsors. The current European project has funding. The Université Grenoble Alpes foundation is now running a campaign to fund the Bolivian expedition.
Here’s hoping the money will be forthcoming.
And here’s hoping the international community will speed up efforts to halt global warming before we have to create archives to try to document all the ecosystems, species and habitats we are losing faster than we can count them.
