The Upper New York Bay is a bay south of Manhattan in the U.S. states of New York and New Jersey. It is the northern part of the Bay of New York, which continues from the Lower New York Bay and the channel The Narrows, which connects the two bays is. The Upper New York Bay forms the central part of the port of New York.


The bay is bordered by the southern tip of Manhattan to the north, the New York City borough of Brooklyn in the east, Staten Iceland and the channel The Narrows in the south and Bayonne and Jersey City in New Jersey in the west. The Straits The Narrows connects the Upper New York Bay and Lower New York Bay and finally the Atlantic Ocean. This strait provides with strong tidal current for a high water exchange with the Atlantic, but it also provides a natural protection for the Bay dar. The Hudson River and the East River, which forms the connection to the Long Iceland Sound, end in the bay. About the Kill Van Kull to the south of Bayonne Bay with Newark Bay is connected, which is also affected by the tide. About 100,000 tons of suspended solids from the Upper New York Bay By the tides of electricity annually transported into the Newark Bay, the sediment there. The Passaic River and Hackensack River empty into the Newark Bay and eventually drain through the Kill Van Kull also in the Upper New York Bay.

In the bay there are numerous islands, the largest being Governors Iceland, Iceland Liberty and Ellis Iceland and the large underwater reef Robbins Reef, on the side of New Jersey. The reef is marked by the lighthouse Robbins Reef Lighthouse on a small island. Previously, the reef was one of the largest oyster beds in the world. With the increase in water pollution end of the 19th century, the oysters disappeared from the bay.

Also located in the bay on the side of the Brooklyn Gowanus Bay, a small bay in front of Red Hook, the Buttermilk Channel, the waterway between Brooklyn and Governors Iceland and the Bay Ridge Channel on the eastern side of the bay in front of the Narrow. On the western side is the Greenville Channel and the Claremont Terminal Channel.

Physical parameters

The waters of the bay consists of fresh water from the Hudson River and salt water that comes through the tidal current, mainly through the Narrows channel and the East River. In the bay, these water masses mix. The average replacement time of water in the bay is about two weeks, the proportion of the Hudson River it is negligible. Would the water be replaced by the Hudson River, the mean replacement time would be approximately 5 months. Therefore, the water in the bay consists mainly of salt water marine origin with brackish water contents near the mouth of the Hudson River.


The Staten Iceland Ferry crossing the bay on their half-hour drive between Whitehall Street in Manhattan and St. George Ferry Terminal on Staten Iceland.

The Owls Head sewage treatment plant in Bay Ridge, a neighborhood of Brooklyn, leads the treated wastewater of about 750,000 people in the bay.

The Brooklyn - Battery Tunnel, the road link between Manhattan and Brooklyn, runs beneath the bay.

Large parts of New York are about 3 meters above the sea level. To protect these areas against a flood of the century, studies have been produced to show that it is possible with three weirs the Upper New York Bay and complete the attached water and thus to protect the urban area, similar in London with the Thames Barrier is already made.
