Why do we care? CARBON in global warming context: • Permafrost degradation • Frozen organic carbon exposure -> greenhouse gases (GHG) release • Positive feedback called Permafrost Carbon Feedback What about the MINERAL constituents? • New exposure of buried minerals to weathering agents (water, air, freeze-thaw action) • Potential impact on the fate of organic carbon upon permafrost degradation • Crucial to quantify the mineral element content in the permafrost
