CMSI and Delta Stewardship Council Symposia

About the Event:

Please join the UC Davis Coastal and Marine Sciences Institute and the Delta Science Program for a one-day symposium exploring the impacts of microplastics on aquatic ecosystems, with a focus on the heavily urbanized San Francisco Bay Delta and its diverse habitats. Learn about how these tiny pollutants affect organisms and discuss challenges in studying them and strategies for remediation and standardization.

The symposium will run from 9:00 AM - 4:00 PM on Friday, May 9th, 2025 on the UC Davis campus and will also be live-streamed and recorded. This is a ticketed event for in-person and remote attendees.
