The Sandy Hook Pilots are licensed maritime pilots for the entire Port of New York and New Jersey, the Hudson River, and Long Island Sound who go aboard oceangoing vessels, passenger liners, freighters, and tankers,to guide them in and out of the harbor.
 The peninsulas of Sandy Hook and Rockaway in Lower New York Bay define the southern entrance to the port at the Atlantic Ocean.
The East River is a salt water tidal estuary in New York City.
 The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end.
 It separates the borough of Queens on Long Island from the Bronx on the North American mainland, and also divides Manhattan from Queens and Brooklyn, which is also on Long Island.
 Because of its connection to Long Island Sound, it was once also known as the "Sound River".
 The tidal strait changes its direction of flow frequently, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths.
 The waterway is navigable for its entire length of 16 mi , and was historically the center of maritime activities in the city, although that is no longer the case.
The Harbor Defenses of Long Island Sound was a United States Army Coast Artillery Corps harbor defense command.
 It coordinated the coast defenses of Long Island Sound and Connecticut from 1895 to 1950, beginning with the Endicott program.
 These included both coast artillery forts (all but two on islands in the sound) and underwater minefields.
 The area defended included the approach via the Sound to New York City, the port cities and manufacturing centers of New London, New Haven, and Bridgeport, and eventually included the submarine base and shipyard in Groton.
 The command originated circa 1900 as an Artillery District, was renamed Coast Defenses of Long Island Sound in 1913, and again renamed Harbor Defenses of Long Island Sound in 1925.
USRC "Manhattan" was an iron-hulled harbor tug that served as a Revenue Cutter and was originally assigned to New York City harbor and Long Island Sound, but in 1875 she was moved to the Great Lakes with stations at Ogdensburg and Oswego, New York.
 After 1885 she was advertised for sale but was withdrawn and reassigned to the Hudson River and Long Island Sound.
 After decommissioning in 1917, she was moved to Baltimore, Maryland and renamed "Arundel" because a new "Manhattan" was being built.
 Although no longer in commission, she served as a station vessel until sold in 1927.
Eastchester Bay is a protected body of water between City Island and the mainland Bronx, New York.
 Technically, it is a sound, not a bay, since it is open to larger bodies of water at both ends.
 The northern end connects via a narrow channel to Pelham Bay (which is also really a sound, since it, in turn, opens onto Long Island Sound).
 The Hutchinson River empties into Eastchester Bay near the northern end.
 The lower portion of the bay opens onto the East River, Little Neck Bay, and Long Island Sound.
U.S. Coast Guard Station Montauk is located on the easternmost end of Long Island in Montauk, New York.
 Station Montauk was officially opened on October 1, 1955 and has remained an active Search and Rescue and Law Enforcement unit.
 Today the station is one of eight small boat units that are a part of Sector Long Island Sound.
 Station Montauk is made up of active duty, reserve, and auxiliary personnel to maintain watch over the south shore of Long Island and Long Island Sound.
Captain Joseph Henderson (September 9, 1826 - October 7, 1890) was an early American harbor pilot who guided large vessels in and out of the New York harbor.
 He was a legendary figure in New York during the 1880s, well known for being one of the oldest and wealthiest of the Sandy Hook Pilots, which operated in what is now the Port of New York and New Jersey.
 He was recognized to all the large steamship owners as one of the most experienced and trustworthy New York pilots.
Glacial Lake Connecticut formed over what is now Long Island Sound and coastal Connecticut at the fore edge of the ice sheet of the Wisconsin glaciation, as the lobe of the Laurentide ice sheet began to retreat, some 18 to 20,000 years before present.
 It was dammed by the terminal moraine that now forms the spine of Long Island and Fishers Island.
 About 15,000 BP, the moraine dam that impounded Lake Connecticut failed; the outlet, known as The Race for its tidal rip currents, lies between the North Fork of Long Island and Fishers Island.
 For a time, much of the lake bed was exposed to wind-driven erosion: the cue is found in soundings that reveal regional unconformities in the sediment bed of Long Island Sound.
Long Island Sound is a tidal estuary of the Atlantic Ocean, lying between the eastern shores of Bronx County, New York City, southern Westchester County, and Connecticut to the north, and the North Shore of Long Island, to the south.
 From east to west, the sound stretches 110 miles (177 km) from the East River in New York City, along the North Shore of Long Island, to Block Island Sound.
 A mix of freshwater from tributaries and saltwater from the ocean, Long Island Sound is 21 miles (34 km) at its widest point and varies in depth from 65 to .
The Saw Mill River is a 23.5 mi tributary of the Hudson River in Westchester County, New York, United States.
 It flows from an unnamed pond north of Chappaqua to Getty Square in Yonkers, where it empties into the Hudson as that river's southernmost tributary.
 It is the only major stream in southern Westchester County to drain into the Hudson instead of Long Island Sound.
 It drains an area of 26.5 sqmi , most of it heavily developed suburbia.
 For 16 mi , it flows parallel to the Saw Mill River Parkway, a commuter artery, an association that has been said to give the river an "identity crisis."
