Project Title

Ice Sheet Variability 300 Million Years Ago as an Analog to Modern Climate Change

The goal of my PEI summer internship was to study rocks and other geological features in order to understand the climate of Earth’s ancient history and in turn, to better understand future climate change. By collecting and studying rocks that preserved oxygen isotopes deposited 300 million years ago, we can better understand the extent of global glaciation from that time period. As a part of this internship, I spent the summer hiking in Nevada, Utah, Wyoming, and Colorado. Not only did I get to see amazing parts of the American west, but I also learned how to collect data in the field. Having known nothing about geology, I learned a great deal about the basics of geology and began to make sense of the physical world around me. I learned how to see and identify fossils as well as many different types of rock formations. This internship expose me to not only geology, but also to a part of America that I had never seen before. While the internship did not necessarily persuade me to major in geology, it did show me that the more you know about the physical world, the more amazing and beautiful it becomes.
