In San Luis Obispo County, California, protecting our creeks and coastlines is a shared responsibility. The estuary, teeming with life and natural beauty, faces growing threats from pollutants that enter through creeks and rivers, impacting the delicate ecosystems that depend on clean waters. One Cool Earth wanted to help tackle these concerns.

San Diego Bird Alliance is a local leader that shares the value and restoration potential for tidal wetland ecosystems. In South San Diego Bay, our remnant tidal wetlands are fragmented, heavily impacted by the development around them, and changing as sea levels rise. San Diego Bird Alliance brings the community to these natural habitats to share and learn about the species that live there and how they need protection and space to live and thrive.

Located in Imperial Beach, California, the Tijuana River National Estuarine Research Reserve (TRNERR) sees challenges as opportunities to utilize trinational collaboration in addressing the social-ecological impacts of marine debris. With support from the National Oceanic and Atmospheric Administration Marine Debris Program (NOAA MDP) provided through the United States-Mexico-Canada Agreement Implementation Act, the ResiDUOS project was created to collaboratively develop a community-driven circular economy pilot project, capture and characterize trash, remove debris in critical natural habitats, and develop a binational emergency response guide to flooding. 

Where does marine debris originate, and how does it make its way to the ocean? There are many possible avenues for land-based trash to become marine debris. In Southern California, San Diego State University (SDSU)  is working to find the answers. This multi-departmental project at SDSU is quantifying marine debris in the highly urbanized San Diego River and working to better understand how it travels through our waterways. 

New Report: Marine Debris on the shoreline of Monterey Bay National Marine Sanctuary: An assessment of activities contributing to marine debris, categories and composition, spatial distribution and predictor variables.

The NOAA Marine Debris Program supports various partners involved in marine debris research, prevention, and removal throughout California. Local universities, nonprofits, and state and federal agencies make up the many hands that are addressing microplastics, single-use plastics, fishing gear, and large-scale marine debris, such as abandoned and derelict vessels. From up north, to down south, and across shared border communities, these partners and their efforts create a comprehensive response to California’s marine debris issues.

In 2020, I began my California Sea Grant Extension Fellowship with the National Oceanic and Atmospheric Administration’s Marine Debris Program. I was brought on to help the California Regional Coordinator implement marine debris projects and strategies in California. Over the course of my fellowship, I had the opportunity to lead a statewide marine debris action plan, support strategic internal efforts, and partake in countless professional development opportunities. This experience has improved my confidence as a young professional, guided my career path, and has certainly prepared me for my next chapter and future career.

Staff, faculty, and students at California State University Channel Islands (CSUCI) Santa Rosa Island Research Station have been working to monitor and remove marine debris from portions of Santa Rosa and Santa Cruz Islands since 2015. With support from the NOAA Marine Debris Program, over 7,500 pounds of debris have been removed from the islands since 2020. This three-year project is an extension of past research and collaborative efforts of partners across the Channel Islands. CSUCI invited the NOAA Marine Debris Program California Regional Coordinator and the program’s California Sea Grant Extension Fellow for a week-long site visit to remove and assess the amounts, types, and sources of marine debris on Santa Rosa Island.

Much of San Francisco’s beauty comes from its stunning location, surrounded by the Pacific Ocean and San Francisco Bay. San Francisco is also the second-most densely populated city in the United States and one of the country’s most-visited destinations. With so many people near so much water, the marine environment is especially vulnerable to all forms of human-made pollution, including cigarette butts, the most littered item in San Francisco and around the world.

About 70% of Californians believe their ocean and beaches are very important to California’s future and report that plastics and marine debris are a big problem on a coast near them. As a result, organizations, individuals, and volunteers from across the state are contributing an enormous and noble amount of time and energy to make California a national leader on addressing and preventing marine debris.
