Estuario Weekly Update

Happy Thanksgiving!

During these holidays, we thank the neighbors, friends, volunteers, collaborators, donors, and the team that make possible our work of restoring and managing the San Juan Bay Estuary and its interconnected ecosystems.

Below, we share opportunities for collaboration, volunteering and training for this week, through initiatives and actions programmed for the benefit of the ecosystems of the San Juan Bay Estuary and their communities.

Employment opportunities

Join our team. Here are our open listings: 

The coordinator must enthusiastically integrate all sectors into the event and lead their participation, considering and improving upon the data from previous years. The coordinator’s primary goal should be access to clean and safe water for all in Puerto Rico.

Our work to restore and manage the San Juan Bay Estuary is made possible thanks to collaborations with citizens, municipalities, and government agencies (among others); through the exchange of infrastructure and scientific and technical data to support effective projects. However, beyond infrastructure, the most precious resource of the Estuary and its collaborators is an informed and involved public.

With this goal in mind, we are training citizens in environmental restoration practices through our certification of citizen scientists in coastal resilience. This effort requires an investment of approximately $100,000 per year. A donation from you en route to this #GivingTuesday helps us get closer to this goal and continue to train, reforest, and collect data to improve the quality of our waters.

#GivingTuesday takes place on Tuesday, November 28, 2023. There are multiple ways you can donate. Find out how, at:
