Collecting ice cores from glaciers most at risk from climate change and storing them in Antarctica for future generations of scientists : that is the goal of ICE MEMORY, an international programme aimed at preserving the climate and environmental memory of glaciers.

Following the two successful drillings in the Col du Dôme glacier in French Alps in August 2016 and on the Illimani glacier in Bolivia in June 2017, two further drilling expeditions will be conducted in Russia in May and June 2018.

May : drilling operation on Belukha glacier, Siberian Altai

From May 20th to June 16th, a drilling operation will take place on the Belukha glacier, coordinated by Margit Schwikowski, head of the Environmental Chemistry Laboratory and head of the Analytical Chemistry Group at the Paul Scherrer Institute in Switzerland.

The Belukha glacier is located on a saddle between the two summits of Belukha, the highest mountain in the Altai (4,506 m a.s.l.). The Altai mountain range is a remote area on the northwestern periphery of central Asia, at the border between east Kazakhstan, southwest Siberia, northwest China, and Mongolia. The region is of particular interest for paleo research because of its high continentality and its location on the boundary between Siberian forests and arid regions in central Asia.

Ice cores were already collected from Belukha glacier in 2001 and 2003, demonstrating that this is most probably the only site suitable for ice core studies in this region. Although ice temperatures were below -14°C, melt layers were observed in the upper part due to a recent strong increase of summer temperatures. To preserve this valuable environmental archive, there is an urgent need to collect further ice cores.

The drilling operation on Belukha glacier will start around May 20th. The equipment was shipped from Switzerland to Barnaul in Siberia and will be transported together with the drilling team by helicopter to the glacier. The main goal is to recover two new cores down to bedrock, each of ca.150 m lengths using an electromechanical drill. The drilling team will spend about 20 days on the glacier. Ice cores weighing about 1.5 tonnes will be transported by helicopter to the nearest road and then in freezer trucks to the storage facility in Barnaul.

One ice core will be analysed for stable isotopes, major ions, trace elements, black carbon, and organic tracers to create a reference data base while the parallel ice core will join international repositories as part of ICE MEMORY.

This drilling is a joint project of the Institute for Water and Environmental Problems, Siberian Branch of the Russian Academy of Sciences (IWEP-RAS, Barnaul) and the Paul Scherrer Institute (PSI Villigen, Switzerland), financially supported by the Swiss National Science Foundation and the Swiss Polar Institute.

June : drilling operation on Elbrus glacier, Caucasus

From June 10th to July 25th, a drilling operation will take place on Elbrus glacier, in Caucasus, coordinated by Vladimir Mikhalenko and Stanislav Kutuzov (Institute of Geography, Moscow).

Elbrus, the ice-covered Europe’s largest volcanic massif (5,642 m), is located in Caucasus mountains at Southern Russia. Elbrus glacial system with the total glaciated area of about 115 km2 contains more than 10% of the total ice volume in the Greater Caucasus. The Baksan, Kuban, and Malka Rivers runoff from the Elbrus glaciers irrigates agricultural lands on steppe plains of the North Caucasus.

Due to its altitude above 5,000 m above sea level, melting ceases completely. Elbrus is one of the few glaciers in Europe where the climate signal is preserved undisturbed. Results of the first ice core drilling operation in 2009 showed that ice cores from the Elbrus Mountain can provide unique information about several key aspects of the changing environment, air pollution and volcanic activity.

Ice core data can be used to reconstruct past conditions, not only in Caucasus but for a much broader region, including Western and Eastern Europe, Southern Russia and the Middle East. It is anticipated that This drilling is a joint project of the Institute for Water and Environmental Problems, Siberian Branch of the Russian Academy of Sciences (IWEP-RAS, Barnaul) and the Paul Scherrer Institute (PSI Villigen, Switzerland), financially supported by the Swiss National Science Foundation and the Swiss Polar Institute. continues ice core record will cover more than 500 years. Furthermore, the rate of Elbrus’s glacier reduction has increased significantly in recent decades. Therefore, there is an urgent need to preserve this valuable environmental archive.

For this drilling, the ice core drill already used at Mont- Blanc and Illimani will be implemented. 600 kg of equipment has been shipped between the IGE laboratory (Institut des géosciences de l’environnement, Grenoble) and Moscow. All this logistics and customs formalities were conducted by ULiSSE (International Logistics Unit – Services and Support to Experiments, Annecy), the logistics unit of the CNRS.

Since the end of May, the team of 7 researchers will start to acclimatize to high altitude conditions with the help of professional mountain guides. In June, equipment and personnel will be transported by helicopter to the drilling site at 5,100 m. The main goal is to drill glacier down to bedrock and to retrieve two 240 m long ice cores. Drilling will be accomplished using electromechanical drill and the whole operation will take about 25 days. Frozen ice cores of 3 tones weight will be transported first down to the nearest paved road by helicopter and in freezer trucks to the storage facility of the Institute of Geography (Russian Academy of Science, Moscow), where primary processing will be carried out.

One of the ice cores will be analysed by an international team of scientists at the IGE laboratory (CNRS/IRD/ UGA/Grenoble INP) in 2019, in order to identify chemical tracers available with current technologies and to create an open database accessible for the scientific community, being today or in the future.

The analytical platform of the IGE brings together all the analytical infrastructures, highest level instruments and technologies necessary for optimal exploitation of ice cores. Russian researchers and students will take advantage of this platform to enhance the Elbrus reference core results and produce innovative scientific discoveries.

Another ice core will be entrusted to international repositories. It will contribute to the world’s first ice archive sanctuary, relying on glaciers threatened by global warming. An ideal location for this repository will be Antarctica. A document for that purpose will be presented at the next consultative meeting of the Antarctic Treaty by Parties. The Antarctic Treaty system is the competent framework to address the issues related with Antarctica.

Elbrus drilling operation and ice core analysis are supported by the Russian Science Foundation grant 17-17-01270 and by ICE MEMORY program. The expedition to Elbrus will is supported by the Institute of Geography Russian Academy of Sciences, which celebrates 100th anniversary in 2018. To celebrate this jubilee a large international scientific conference will be held in Moscow in June where leading scientists and geographers from all over the world will take part. This conference is supported by the corporation "Russian textbook", Russian Geographical Society, WWF Russia, RFBR.

More information

Backed by the Université Grenoble Alpes Foundation, ICE MEMORY project unites the following partners : CNRS, IRD, Université Grenoble Alpes, National Research Council of Italy, Ca’ Foscari University of Venice, Paul Scherrer Institute in Switzerland as well as IPEV (French Polar Institute) and the Italian Antarctic research programme (PNRA) as regards the cold chain logistics between Europe and the Antarctic plateau as well as the long-term storage at their jointly operated Concordia station which could be a hub for that purpose. The project is equally jointly financed by the provision of human resources and equipment from partner scientific organisations and by private sponsorship, through the Université Grenoble Alpes Foundation. UGA’s Foundation is happy to welcome a new 3 years Swiss based philanthropic partner : the Didier and Martine Primat’s Foundation.
