Classroom/Laboratory Activity: Reconstruction of Paleoclimate by Using Isotopic Composition Data


Students will plot graphs to analyze data from the Vostok ice core in Antarctica, learn about the ice age and the gas age, calculate past temperatures using hydrogen isotope data, and discuss the possible impacts of changes in carbon dioxide (CO2) and methane (CH4) concentrations on climate.

Use this tool to help your students find answers to:

  1. How can you use hydrogen isotope data in an ice core to determine temperature?
  2. How can the isotopic composition of air bubbles in ice cores be used to recreate past climate?

Classroom/Laboratory Activity (in French): Using Oxygen Isotopic Compositions to Determine Past Climate

A classroom/laboratory activity to learn about oxygen isotopes (18O and 16O); understand the relative distribution of these isotopes in the atmosphere, ocean, and cryosphere; and explore how the concentration of these isotopes can be used as indicators of paleoclimate.
