The mission of the USC Wrigley Institute for Environmental Studies is to encourage responsible and creative decisions in society by providing an objective source of marine and environmental science and fostering an understanding of the natural world among people of all ages.

Our affiliated faculty conduct research in all aspects of the environment. Wrigley Institute scientists investigate biological adaptations to climate change, study interactions among humans and natural systems, and connect science to environmental policy. We also offer unique educational programming and work with foundations and the public to enhance environmental awareness.

2015 is the 20th anniversary of the Wrigley Institute, and the 50th anniversary of our Wrigley Marine Science Center on Catalina Island. Join us as we celebrate this heritage of science and discovery at USC. Here’s to the next 50!
