Activity Summary: Students will be able to analyze oxygen isotope data from sediment cores to understand the occurrence of Heinrich Events.

This lesson has students analyze oxygen isotope and ice rafted debris (IRD) data to identify major climate fluctuations, correlating those to the Greenland Ice Core (GISP2), and determining if those changes were global or regional in impacts. Prior to this lesson, students should be familiar with the general concept of climate change, in addition to having some knowledge of ice ages.

This lesson has been revised and updated based on Inquiry into High-Resolution Ice Core and Marine Sediment Records.
