Lake Worth Lagoon Drift Card Study

Citizen Scientists
Cards Reported


The Lake Worth Lagoon Drift Card Study (AKA Lagoon Drift) is a citizen science program that uses a series of coordinated releases of small eco-friendly wooden drift cards to study the motion of water and pollutants in waterways in and around the Lake Worth Lagoon. The study solicits the help of local community members in creating, decorating, deploying, locating, and reporting found drift cards to get a better understanding of how marine debris is transported and accumulates in our area. ANGARI Foundation and our Palm Beach County partners also use this project as a tool to engage the community in the conversation about human impacts on the environment, including plastic pollution and other types of marine debris, and the effects they have on marine life.

Palm Beach County Lagoon Drift experiments began in 2017 as an extension of the Biscayne Bay Drift Card Study (AKA Bay Drift) initiated by the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE) at the University of Miami. CARTHE developed the Bay Drift citizen science project in 2016 in an attempt to understand the origins of the growing marine debris problem seen along Miami shorelines and, in particular, at Vizcaya Museum & Gardens. Educators interested in exploring the findings of the Biscayne Bay Drift Card Study with their students are encouraged to check out CARTHE’s Bay Drift Lesson Plan.

After a year and a half hiatus in response to the COVID-19 pandemic, ANGARI Foundation and their partners were thrilled to have resumed the study in November 2021. They are pleased to have the Lagoon Drift Card Study appear in the Lake Worth Lagoon Management Plan coordinated by Palm Beach County’s Department of Environmental Resources Management and approved by the County’s Board of Commissioners in 2021, and and to have presented on the program at the Lake Worth Lagoon Science Symposium on November 15th, 2022 (copy of presented poster available here). ANGARI and partners are excited to have initiated their 11th Lagoon Drift experiment on April 25th, 2024.



In November 2019, the Lagoon Drift program was also piloted in the Indian River Lagoon under the direction and coordination of the Florida Department of Environmental Protection (FDEP) – Indian River Lagoon Aquatic Preserves, extending the experiment coverage area from Palm Beach County north to Brevard County. The Indian River Lagoon experiments were also paused in response to the COVID-19 pandemic, but the regional partners pulled together to release cards for their Indian River Lagoon Drift experiment in conjunction with the Lake Worth Lagoon programs in November of 2021 and 2022.


  1. Drift cards (40 from each locality) are  simultaneously released from sites around the Lake Worth and Indian River Lagoons.
  2. Drift cards float on the water surface and are carried by local currents.
  3. Citizen scientists (this could be you!) recover the drift cards and report the location, date and time found with a photo of the drift card to the email address designated on the card.
  4. We gain new insights into the way marine debris moves in and around Florida’s coastal waterways.

  • Follow ANGARI Foundation on Facebook to learn more about the project and upcoming Lagoon Drift oriented events.
  • Take to the water in the weeks that follow Lagoon Drift card releases. If you find a drift card, please keep it and follow the stamped instructions to report all requested info.
  • Make a commitment to combat marine debris by picking up and properly disposing of trash you see around town, at the shore or on the water! For best practices, including tips for safely handling debris in light of COVID-19, visit the Ocean Conservancy’s website.
