Throgs Neck Lighthouse
Throgs Neck Light in Throggs Neck, the Bronx, New York, was a wooden lighthouse that was replaced by an iron skeletal tower that is still there. The lighthouse protects ships in the Long Island Sound from running up against the rocks. The lighthouse is located on the northeasterly side of Fort Schuyler, southeasterly end of Throgs Neck and on the northerly side of the entrance from Long Island Sound into the East River The East River is a saltwater 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 .... * Tower Shape / Markings / Pattern: White, square, pyramidal, * skeleton iron tower; lantern, black (1890); Red brick cylindrical tower (1906) * Height: (1890); (1906) Chronology * Original wooden lighthouse established in 1827.

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

If each borough were ranked as a city, the Bronx would rank as the ninth-most-populous in the U.S. Of the five boroughs, it has the fourth-largest area, fourth-highest population, and third-highest population density.New York State Department of Health''Population, Land Area, and Population Density by County, New York State – 2010'' retrieved on August 8, 2015.

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Island Sound
Long Island Sound is a marine sound and tidal estuary of the Atlantic Ocean. It lies predominantly between the U.S. state of Connecticut to the north and Long Island in New York to the south.

Fort Schuyler
Fort Schuyler is a preserved 19th century fortification in the New York City borough of the Bronx. It houses a museum, the Stephen B. Luce Library, and the Marine Transportation Department and Administrative offices of the State University of New York Maritime College. It is considered one of the finest examples of early 19th century fortifications. The fort was named in honor of Major General Philip Schuyler of the Continental Army. History Fort Schuyler was one of many forts built along the east coast of the United States under the third system of US fortifications in the aftermath of the War of 1812, when it became apparent that the U.S. coast was poorly defended against foreign invasion. Fort Schuyler was begun in 1833 and dedicated in 1856 after 75% completion, though not garrisoned until 1861. The fort was strategically positioned to protect New York City from naval attack through Long Island Sound, guarding the eastern entrance to New York Harbor. It is located on Thr ...

East River
The East River is a saltwater 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, also on Long Island.Hodges, Godfrey. "East RIver" in Jackson, pp.393–93 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 , and was historically the center of maritime activities in the city. Formation and description Technically a drowned valley, like the other waterways around New York City, the strait was formed approximately 11,000 years ago at the e ...
