The New York–New Jersey Harbor Estuary is a vital waterway that connects the Atlantic Ocean to the Hudson River and New York Harbor. It's a 150-mile-long estuary that's home to over 20 million people.
Located between the states of New York and New Jersey, the estuary is a unique and complex ecosystem that supports a wide variety of marine life. The estuary's diverse habitats, including salt marshes, mudflats, and rocky shores, provide a home for over 300 species of fish, shellfish, and other marine animals.
The harbor estuary is also a major transportation hub, with cargo ships, tankers, and ferries passing through it every day. The estuary's busy shipping lanes and ports support a significant portion of the region's economy.

The Harbor Estuary
The Harbor Estuary is a crucial part of the New York–New Jersey Harbor Estuary, hosting a bi-state conversation about its future with the Sustainable Raritan River Initiative in 2015.
In 2015, a collaborative effort called "Two States; One Bay" brought together stakeholders to discuss the future of Raritan Bay.
Public Access
The Harbor Estuary's public spaces are a treasure trove for outdoor enthusiasts. The Public Access Work Group is working hard to improve access to the waterfront and waterways for activities like boating, fishing, and swimming.
Assessing the needs and challenges of underserved areas is a key part of their mission. By doing so, they're able to identify areas that need improvement and prioritize their efforts.
Community stewardship is also a top priority for the Public Access Work Group. They're working to advance the quality of public spaces and encourage community members to take ownership of their local waterfront.
By improving public access to the Harbor Estuary, the Public Access Work Group is helping to create a more inclusive and enjoyable experience for everyone.
Two States; One Bay
In 2015, a groundbreaking conversation took place about the future of Raritan Bay, involving both New Jersey and New York states. This initiative was called "Two States; One Bay 2015" and was hosted jointly with the Sustainable Raritan River Initiative.
This conversation was a significant step towards a shared vision for the bay's future, recognizing the importance of collaboration between the two states.

Understanding the navigational channels in the harbor is essential for anyone interested in maritime trade or simply exploring the Port of New York and New Jersey.
Environmental Impact
The New York-New Jersey Harbor Estuary has a significant environmental impact, largely due to hundreds of years of urbanization and industrialization. This has led to the alteration and loss of shallow water, bottom, shoreline, and vegetated habitat.
Poor water and sediment quality have degraded ecological communities, threatening various species and affecting recreational enjoyment of the area. Elevated concentrations of contaminants in fish and shellfish have caused warnings for people not to eat or limit their consumption of certain animals.
Over 100 species of fish occur within the Hudson-Raritan Estuary, but contamination can restrict commercial and recreational fishing, and even alter the public's perception of the area's value.
Key Findings

The New York-New Jersey Harbor and Hudson-Raritan Estuary are facing significant environmental challenges due to centuries of urbanization and industrialization. This has led to a tremendous alteration and loss of shallow water, bottom, shoreline, and vegetated habitat.
Over 100 species of fish occur within the Hudson-Raritan Estuary, but poor water and sediment quality have altered ecological communities, threatening a variety of species. This has negatively affected recreational enjoyment of the area and even led to warnings about eating fish and shellfish caught in the area.
The natural geography of the area continues to concentrate a tremendous variety of wildlife. However, restoring these natural resources is critical for the full benefits of this urban area to be realized for both people and wildlife.
Here are some key statistics about the waterfront in the Harbor Estuary:
Twelve waterfront areas, from the Bronx to the mouth of the Raritan River, are identified as higher need waterfront areas due to the limited number of parks, densely developed housing, or an otherwise disadvantaged population.
Microplastic Pollution in NY/NJ Bay
The NY/NJ Bay is home to a staggering amount of microplastic pollution, with over 165 million particles floating in the estuary at any given time. This is according to a study by the NY/NJ Baykeeper, which found that 85% of the plastic particles counted were microplastics less than 5 mm in size.
Poly-styrene foam was the most abundant type of plastic found in the study, making up a significant portion of the total 6,932 particles of plastic counted. The Baykeeper's analysis also revealed that 38% of the microplastics were less than 1 mm in size.
To put this into perspective, imagine the sheer number of plastic particles that are present in the water. It's a staggering thought, and one that highlights the urgent need for action to address microplastic pollution in the NY/NJ Bay.
Here are some simple ways you can help reduce microplastic pollution in the NY/NJ Bay:
- Say "no" to plastic straws and other single-use items
- Use reusable items like grocery bags, lunch bags, and water bottles
- Ban or place a fee on plastic grocery bags
- Abide by proper recycling and disposal techniques
- Use personal care products that don't include plastic microbeads
- Participate in river and shoreline clean-ups
By making these small changes, you can help reduce the amount of microplastic pollution in the NY/NJ Bay and protect the health of the ecosystem.
Education and Awareness
The Hudson-Harbor Educators Work Group brings together educators from across the estuary to share best practices and foster stewardship of the waterways.
The group's efforts include promoting harbor literacy, engaging communities and youth in stewardship and outdoor activities, and advancing collaboration amongst peers.
Educators are working together to make a positive impact on the estuary.
The NY/NJ Baykeeper is on a mission to understand the plastic's journey and is engaging others to get involved in tracking plastics pollution in the NY-NJ Harbor waterways through the Baykeeper Plastic Story website.
Nearly 80% of trash found in marine waters comes from terrestrial sources, and between one- to two-thirds of the trash on beaches is single-use disposable plastics.
Changes in public consumption and disposal habits can dramatically decrease the amount of microplastics making it into the waterways and into the aquatic food chain.
Source reduction is the most effective way to reduce marine debris.
