June 2018 – Elbrus

Caucasus Mountains – Russia – 5,642 m
Elbrus, Ice Memory, expedition
In June 2018, Ice Memory reached Mount Elbrus in the Caucasus, where high-altitude ice preserves more than 500 years of climate and environmental history. Despite challenging weather conditions, the team recovered two deep ice cores measuring 150 and 120 metres.

Objectives and key results

Number of ice cores drilled: 2
Drilling depth: 150 m and 120 m
Climate record retrieved: More than 500 years

In June 2018, two deep ice cores were successfully extracted from Mount Elbrus, Europe’s largest ice-covered volcanic massif.
These cores preserve over five centuries of environmental and climatic history in the Caucasus region.

Why this site?

Mount Elbrus (5,642 m) is located in the Greater Caucasus, southern Russia. Covering approximately 115 km², its glacial system contains more than 10% of the total ice volume of the Greater Caucasus.
Several major rivers — the Baksan, Kuban and Malka — originate from the Elbrus glacier, sustaining agricultural lands and plains in the North Caucasus.
Elbrus was selected because:
  • Its high altitude (>5,000 m) ensures relatively well-preserved ice
  • It remains one of the few European glaciers where climate information is still largely intact
  • Previous drilling (2009) demonstrated its potential to provide unique data on environmental change, atmospheric pollution and volcanic activity
Continuous ice records from Elbrus can document approximately 500 years of regional climate history.
However, glacier shrinkage has accelerated in recent decades, increasing the urgency to preserve this archive.

Elbrus, Ice Memory, expedition

The expedition

Period: June 2018
Duration: More than five weeks
Conditions: Extremely difficult and unusual weather for the season

The expedition faced severe weather conditions that prevented drilling to the targeted depth of 250 m (bedrock).
Despite these constraints, the team successfully extracted two deep ice cores measuring 150 m and 120 m.

The team

The mission was coordinated by the Institute of Geography (Russian Academy of Sciences, Moscow).
The international team included:
  • Vladimir Mikhalenko, Institute of Geography, Moscow (Coordinator)
  • Stanislav Kutuzov, Institute of Geography, Moscow (Coordinator)
  • Ivan Lavrentiev, Institute of Geography, Moscow
  • Andrey Smirnov, Lomonosov Moscow State University
  • Pavel Toropov, Lomonosov Moscow State University
  • Nelly Elagina, Institute of Geography, Moscow
  • Anna Kozachek, Arctic and Antarctic Research Institute, St. Petersburg
  • Sarah Del Ben, Film Director (Wild-Touch, France)

Scientific analysis

Initial analyses are being carried out at the Institute of Geography of the Russian Academy of Sciences (Moscow).
The Elbrus ice cores provide essential data for understanding:
  • Long-term climate variability in the Caucasus
  • Atmospheric pollution history
  • Volcanic activity signals
  • Regional environmental change
