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.

Water Rationing on Catalina


As of September 6th, 2016, Catalina Island will officially enter Stage 3 water rationing due to the ongoing severe drought. WMSC will see our water allotments reduced to 50% of baseline use. We must require visitors to help by restricting laundry use, minimizing showers, and conserving everywhere they can.
