UChicago graduate student uses Alaskan seashells to track climate change

April 29, 2019

Graduate student Caitlin Meadows analyzed 14,000 shells from the Arctic seafloor, which reflect a shift in the ecosystem from arctic to sub-arctic within the last few decades. The pioneering research is the first to track ecosystem changes through seashell samples alone—and scientists hope it will offer a new tool to track climate change in regions where animal populations haven’t been documented as fully.
