Understanding Ice Cores and Climate History by api-110789702 is a document available to read on EtoBox.
An ice core is a cylinder-shaped sample of ice drilled from a glacier that provides direct evidence of past climate and atmospheric conditions. Snowfall each year traps gases, particles, pollen, ash, dust, and salt from the atmosphere and environment, recording information in the layers of ice. Scientists can determine the carbon dioxide and temperature from different eras by analyzing the ratios of oxygen isotopes in the ice. They also date ice cores by understanding the typical ice formation rate and usin
