Jääytimiä
Jääytimiä, often translated as ice cores, are invaluable archives of Earth's past climate. These long, cylindrical samples are extracted from glaciers and ice sheets, primarily in polar regions like Antarctica and Greenland, and also from high-altitude glaciers. They contain layers of ice that have accumulated over thousands, even hundreds of thousands, of years.
The ice itself is a frozen record, trapping atmospheric gases, dust, volcanic ash, and other particulates as
Jääytimiä are crucial for understanding natural climate variability, the impact of human activities on the atmosphere,
