Gases in ice bubbles

This activity focuses on investigating gases trapped in Antarctic ice bubbles to understand past climate conditions. Using ice cores, scientists can extract and analyze gas compositions to reveal historical volcanic eruptions, seasonal patterns, and climate changes. Participants will learn how to set up a drilling process, extract gases, and interpret data on ion concentrations, including sodium, chloride, and sulfate. The study helps identify seasonal changes and provides insights into historical environmental conditions and climate patterns from as early as 1811.

  10. Name ______________________________ date ____________ • SECRETS IN THE ICE questions • What year does it appear that the volcanic sulfate from the unknown 1808-1809 volcano eruption arrived in Antarctica? • ___________________________ • Look at your graph. What patterns do you see among the sodium, chloride, and sulfate ion concentration? • ____________________________________________________________________________ • ____________________________________________________________________________ • ____________________________________________________________________________ • Based on the sulfate ion concentration peaks, when does spring seem to occur? Based on the sodium and chloride ion concentration peaks, when does winter seem to occur? In what months do each of these seasons occur in the SOUTHERN HEMISPHERE?
