Harbor SEALs & MBRP Winter 2025-2026 Update

The New York Harbor SEALs Civic Science Program is a NYC public school initiative that puts students to work on one problem that is already here and accelerating: extreme weather is reshaping shoreline conditions, water quality, and habitat stability in New York Harbor. Harbor SEALs students play a distinctive role in restoration by doing authentic scientific research and service learning, not one-off “exposure” activities. With 40+ high school volunteers and interns, students run student-managed fieldwork and lab work, teamwork, public outreach, marine resource management, and disciplined data management—the operational skills that make climate adaptation work succeed in the real world.

Our work is built for climate resilience and adaptation because restoration decisions are only as good as the data underneath them. Students measure core physical and chemical parameters—temperature, salinity, dissolved oxygen, pH, turbidity (and related indicators)—to assess whether conditions are suitable for oyster and harbor seal survival, growth, and broader habitat function. Those measurements become decision-useful evidence that supports climate resilience planning, adaptive management, and habitat restoration.

We focus on Governors Island and Lower Manhattan because this corridor is an ecological chokepoint: over four miles of shoreline exposed to intense tidal exchange and some of the densest urban pressures in the city. In wet weather, combined sewer overflows discharge stormwater mixed with untreated sewage into surrounding waters—exactly the kind of stressor that spikes during heavy rainfall and undermines long-term restoration gains. New York City’s combined sewer system includes hundreds of CSO outfalls that collectively discharge billions of gallons annually, meaning the water quality story in this corridor is inseparable from extreme weather.

Since 2011, Harbor SEALs students have generated crucial water-quality datasets and removed and catalogued more than 700 kilograms of debris from New York Harbor, including 450 kilograms collected this year alone. Students document debris composition, map accumulation hotspots, and analyze patterns related to tidal flow and storm events—turning cleanup into localized intelligence that directly informs restoration and mitigation strategy.

This proposal is designed to align tightly with Con Edison’s Strategic Partnerships focus on Extreme Weather Adaptation and Mitigation, especially the emphasis on nature-based solutions and protecting vital waterways and wetlands as climate challenges intensify. Harbor SEALs strengthens the resilience of ecosystems and communities by producing the field data needed to target and evaluate blue-green infrastructure: oyster reef restoration, living shoreline work, wetland protection, and the water-quality improvements these projects are expected to support. In other words, we help ensure that nature-based resilience investments are deployed where they will work—and measured in a way that allows continuous improvement.

In the coming year, we will expand this work through three major initiatives:

01) Incorporating artificial intelligence into the workflow.
AI will be used for faster QA/QC, anomaly detection, pattern recognition, and reporting. The point is not novelty—it’s operational speed and reliability. After major rain events, we need to identify changes in water quality, distinguish signal from noise, and communicate actionable findings to partners and the public.

02) Extending comprehensive microplastics, eDNA, & water quality monitoring.
Students will collect and analyze eDNA & microplastics concentrations alongside physical and chemical data across the Governors Island and Lower Manhattan shorelines. This adds a critical resilience lens: eDNA is an emerging technology that quickly assays biodiversity levels in water bodies & microplastics are both a contamination indicator and a chronic stressor that interacts with storm-driven runoff and debris transport.

03) Expanding our long-term monitoring by returning to older stations with professional-grade equipment.
We will reoccupy legacy stations and strengthen comparability over time. Professional instrumentation improves data confidence, strengthens trend detection, and makes the dataset more usable for restoration partners who need defensible evidence.

04) Expand out solar panel array.  We plan to add backup power to our recirculating aquaculture systems using solar renewable technology. As AI become more prevalent in the workforce, training students to build, deploy, and maintain solar power is a critical skill multiplier.

Across these initiatives, students will collect real-time physical and chemical data—including nutrients, pH, turbidity, dissolved oxygen, and other key indicators—and use AI-supported analysis to identify how storm-driven runoff and pollution alter harbor conditions. The deliverable is practical: clearer hotspot maps, faster post-storm interpretation, and stronger evidence for targeted mitigation that improves ecosystem health.

While our core focus is ecological restoration and environmental monitoring, Harbor SEALs is also intentionally structured for equitable climate resilience. We provide stipends for students in leadership roles who keep the workflow functioning—sampling leads, data managers, lab leads, and public outreach leads—so participation is not limited to students who can afford unpaid time. This aligns with Con Edison’s commitment to resilience that is equitable and community-based, and it strengthens local capacity to respond to climate impacts through trained youth leadership.

This work builds on support and collaboration from Con Edison and a strong network of partners, including the Billion Oyster Project, Hudson River Foundation, SUNY Stony Brook, Earth Matter, Bronx Community College, NYU Gallatin, Governors Island Trust, Riverkeeper, Future River, Here On Earth World, Wanderers Club, and Jenny Marketou. These partnerships allow Harbor SEALs to function as a stable platform: long-term monitoring, sustained student leadership development, and ongoing public-facing stewardship in a high-impact corridor.

Harbor SEALs is local by design and global by implication. Students have participated in international research trips to India and the Caribbean (including Cuba with the Wanderers Club) to monitor marine debris and water quality, but the purpose of this proposal is clear: strengthen New York City’s climate resilience where pressure is highest and where nature-based solutions can deliver measurable benefits—if we monitor, learn, and adapt fast enough.

The Marine Biology Research Program celebrates a meaningful milestone this year. For over a decade, our scholars have created personal websites—ePortfolios—to highlight their achievements, career interests, unique strengths, and passions both inside and outside the classroom. These digital showcases not only capture their growth as young scientists but also reflect their individuality and creativity. I encourage you to explore their work through this link and to “Like” the pages you visit to help amplify their voices online.

Our Marine Biology Research and Harbor SEALs scholars are off to an incredible start this year! We’ve launched a wave of exciting collaborations—with Econcrete Co., Deutsche Bank and Nature Metrix, Object Territories, Big Green Theatre, Earth Matter, NYU Gallatin Lab, Stony Brook University, Bronx Community College, the New York Climate Exchange, Harbor SEALs, Riverkeeper, and so many more—on projects exploring PFAS, marine biodiversity, marine debris, eDNA, microplastics, submarine groundwater discharge, weather, and water quality in Cuba, to name just a few.

This last spring, CUNY TV invited our instructor Mauricio Gonzalez to share his insights on water and biodiversity in the Hudson River and along New York City’s waterfront. The following panels feature his contributions to these vital conversations.

We’re also gearing up for our annual Cuba Marine Science Expedition with the Wanderers Club and the University of Habana. A huge thank you to our former superstar Development Officer, Nan Richardson, for her unwavering support of our students, and to our main sponsor, Con Edison, whose generosity keeps our mission afloat—giving hundreds of New York City youth the opportunity to protect and restore the waters of our harbor.

HARBOR TO LA HABANA 2025

The excitement is growing as Harbor SEALs packs to leave for the now-annual winter Cuba Field Expedition! Twenty young science scholars accompanied by Marine Biology teacher Mauricio Gonzalez and English teacher Rosie Teverow is packing to embark on three-part scientific testing in the waters of Cuba, working alongside scientists at the Universidad de Habana’s Centro de Investigaciones Marinas, with Dr. Randy Calderon Pena and his students to compare the marine debris in Havana Bay with that of Hudson-Raritan Estuary (a data set compiled since 2012 by Harbor SEALS) measuring contaminants and physical-chemical parameters. This year, under the director of SUNY StonyBrook’s distinguished professor Dr. Henry Bokuniewicz, SEALS adds another exciting project, on SGDs (submarine groundwater discharges) deploying two drum-sized devices designed to collect seepage data as part of a Pan-Caribbean study the Professor is headlining. The devices were constructed in Harbor’s own Welding CTE (thanks to Clark Dennis and students!). This is an exciting opportunity to participate in important international research with an outcome of a possible published paper (a signal honor for our hardworking students.) The third component is a coral reef project to calculate the percent cover of live, sick, and dead coral in order to determine the health of a reef.

SEALS takes our collective hat off to our partners at The Wanderers Club for their tireless support organizationally in making this experience better each time! And to Special Projects (SEA Chair) at Harbor Nan Richardson who originated the trip as a parent (2020 to Colombia, scuppered by Covid), directed it administratively since, and to the students and their parents who worked so hard to fundraise the needed subsidy of $20,000 through bake sales, raffles, funding campaigns–the grassroots team that makes the dream happen each year!

HARBOR TO LA HABANA 2024

The Harbor SEALs embarked on an excursion of a lifetime – to Cuba! 17 young science scholars tested their tenacity in the waters of Cuba for contaminants and physical-chemical parameters. With marine biology gear and bug spray in tow they hiked to remote and well trodden areas all the same to determine if the waters of Cuba were as contaminated as the New York Harbor.

A major shout out goes to our principal donors Jim Tripp & Jeffrey Gural. We also thank our various other generous donors: Lisa Breslof, Elizabeth Butler, Kristy Chau, Joanna Dje, Michelle Eliseo, Raquel Fernandez, Charles Fitzpatrick, Tracy Hogan, Erlyn Ikeda, Sarah Koo, Bill Ma, Drako Macal, Patricia Madsen, Jane McNamara, Peter Morawski, Kathleen Nolan, Alexis Raskin, Julia Ryan, Julio Rodriguez, Lou Siegel, Edward Smith, Hiram / Owen Szeto, Veronica Torres, Tara Tranchina, Karen Valentin, Jessica Woodall, and Yingdi Xiang, & Nami Yamamoto. We had various anonymous donors and we thank them too!

We would also like to thank our school Project Manager: Nan Richardson, travel managers: Wanderers Club, and our former principal: Jeff Chetirko for making trip possible.

Jan 20, 2024 at 8:15 PM: We’ve made it safe and sound. No issues on the way. We arrived in Havana and we saw scenery that was eye-opening for all of us. When we got to the house, we got situated and had our first proper meal of the day.

Then we played some card games, socialized, and then went on a walk. The walk was peaceful and we took some time to take in the beauty of Havana and the fact that we’re on an international trip with our peers and mentors.

Happy Birthday Scott!

We then set off to our first sampling location, the Habana Bay, to collect data, which went smoothly.

We then headed to a Cuban nature conservatory where we took a guided hike, stopping to collect/test data and eat lunch.

Our days’ work were mapped out the night before on a hand-written schedule. We encouraged thoughtful memes to establish the theme of the day. “Don’t eat the crust!”

Drones? What drones? The phys-chem team is trying to figure out how (not) to use drones in Cuba.

NYC kids planning their next  adventure: soccer game with locals, then Cuban dance!

Data analysis the old-school way! Right Adam!

…and the classic car ride of a life time!

Our final dinner out with our University of Havana science partners.

Hasta Pronto, Cuba bella!
