Waters Surrounding Staten Island: Raritan Bay, Lower NY Bay, Atlantic, Kill Van Kull

**Staten Island** (Richmond County, NYC) sits at the **apex of the New York Bight**, where four distinct water bodies converge:

1. Raritan Bay (West / Southwest): **Estuarine arm** between NJ (Middlesex/Monmouth) and SI. Fed by **Raritan River**, **Arthur Kill**. Shallow, turbid, industrial/urban shoreline (Port of NY/NJ terminals). **Sandy Hook** (Gateway NRA) marks its seaward limit.
2. Lower New York Bay (South / Southeast): **Main gateway** to NY Harbor. Between **Sandy Hook (NJ)** and **Rockaway Peninsula (Queens)**. **Ambrose Channel** (main shipping lane, 45 ft+). **Hoffman & Swinburne Islands** (artificial, quarantine history). **Fort Wadsworth** (SI) guards The Narrows.
3. Atlantic Ocean (South): **Open ocean** beyond Sandy Hook/Rockaway. **Continental Shelf** (Hudson Shelf Valley). **Cold, nutrient-rich.** Beaches: **South Beach, Midland Beach, Cedar Grove, Great Kills, Wolfe's Pond Park.**
4. Kill Van Kull (North / Northwest): **Narrow tidal strait (3.5 mi / 5.6 km)** between **Staten Island (north shore)** and **Bayonne, NJ**. **Critical shipping channel** (Port Newark/Elizabeth — busiest East Coast container port). **Bayonne Bridge** (raised 2017 for New Panamax). **Strong tidal currents (3–4 kts).** Connects **Upper NY Bay / Newark Bay** to **Lower NY Bay / Raritan Bay**.

Additional Connections

• Arthur Kill (West): Tidal strait SI ↔ NJ (Elizabeth, Carteret). **Goethals Bridge, Outerbridge Crossing.** Prall's Island, Shooters Island (bird sanctuaries). Fresh Kills (former landfill → park).
• The Narrows (Northeast): **Verrazzano-Narrows Bridge** connects SI to Brooklyn. **Upper New York Bay** begins here.

Ecological Significance

This confluence creates **critical habitat**: Horseshoe crab spawning (Raritan/Arthur Kill), Diamondback terrapin, Osprey, migratory shorebirds, striped bass, bluefish, winter flounder. **Jamaica Bay Wildlife Refuge** (Queens) nearby. **Superfund sites** (Gowanus, Newtown Creek, Newark Bay) upstream impact water quality.
