Estuario Weekly Update

Through our weekly update we share opportunities for collaboration, volunteering, and work; through initiatives and actions programmed for the benefit of the ecosystems and communities of the San Juan Bay Estuary. These activities, tips and information are for everyone’s benefit.

Estuario Summit 2022

The Estuario Summit 2022 was a success! The event, organized by our Scientific and Technical Advisory Committee (STAC), achieved the participation of over 30 people.  Through this meeting, it was possible to gather a large group of knowledge-holders of the San Juan Bay Estuary who contributed knowledge and ideas from their respective disciplines, in the process of developing a conceptual model of the social-ecological-technological system of the San Juan Bay Estuary as a guide to create conservation programs, research, water quality monitoring and education.

Certification for Citizen Scientists

We’re continuing our current round of introductory workshops for the certification for citizen scientists in the modules of water quality monitoring, characterization and reduction of microplastics, participatory bird censuses and coastal resilience.

Don’t miss the next workshop: Introduction to microplastics and other aquatic debris; Wednesday, November 30, 2022, 7 a.m. – 8 p.m. through Zoom. Sign up today:

Citizen scientists get certified with Estuario’s Coastal Resilience Module

Last Saturday, November 12, 22 volunteers got certified through the Coastal Resilience Module of our Citizen Scientist Certification Program! The group included students majoring in Marine Sciences at the Inter-American University-Bayamón Campus, and the Environmental Sciences Seminar of the University of Puerto Rico, Río Piedras. We also had the support of our new Coastal Resilience Module coordinators: Andreína Alexatos (Green Infrastructure Coordinator) and Patria Aponte (Coordinator of the Coastal Resilience Project), who worked with mangrove planting and monitoring of marine communities, respectively.
