Soldier Key
Soldier Key is an island in Biscayne National Park in Miami-Dade County, Florida. It is located between Biscayne Bay and the Atlantic Ocean, about three miles north of the Ragged Keys, five miles south of Cape Florida on Key Biscayne, seven-and-a-half miles east of the mainland and three miles west of Fowey Rocks. It lies on the Safety Valve, a sand bar that separates Biscayne Bay from the Atlantic Ocean and moderates storm surges into the bay. Geography The island is small, about 200 yards (200 meters) by 100 yards (100 meters) with a maximum elevation of six feet (under two meters). It is at the southern end of the along-shore movement of sand that feeds the barrier islands to the North (such as Key Biscayne) and is the northernmost exposure of the Key Largo limestone (fossilized coral reef) which forms the "true" Florida Keys. The island is covered by grass and shrub vegetation typical of the Florida Keys. Although the island was described as "thickly wooded" in 1894, as of 1 ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Biscayne National Park
Biscayne National Park is an American national park located south of Miami, Florida in Miami-Dade County, Florida, Miami-Dade County. The park preserves Biscayne Bay and its offshore barrier reefs. Ninety-five percent of the park is water, and the shore of the bay is the location of an extensive mangrove forest. The park covers and includes Elliott Key, the park's largest island and northernmost of the true Florida Keys, formed from fossilized coral reef. The islands farther north in the park are transitional islands of coral and sand. The offshore portion of the park includes the northernmost region of the Florida Reef, one of the largest coral reefs in the world. Biscayne National Park protects four distinct ecosystems: the shoreline mangrove swamp, the shallow waters of Biscayne Bay, the coral limestone keys and the offshore Florida Reef. The shoreline swamps of the mainland and island margins provide a nursery for larval and juvenile fish, molluscs and crustaceans. The bay w ...

Biscayne Bay
Biscayne Bay () is a lagoon with characteristics of an estuary located on the Atlantic coast of South Florida. The northern end of the lagoon is surrounded by the densely developed heart of the Miami metropolitan area while the southern end is largely undeveloped with a large portion of the lagoon included in Biscayne National Park. The part of the lagoon that is traditionally called "Biscayne Bay" is approximately long and up to wide, with a surface area of . Various definitions may include Dumfoundling Bay, Card Sound, and Barnes Sound in a larger "Biscayne Bay", which is long with a surface area of about . Etymology Hernando de Escalante Fontaneda related in the 16th century that a sailor from the Bay of Biscay called the ''Viscayno'' or ''Biscayno'' had lived on the lower east coast of Florida for a while after being shipwrecked, and a 17th-century map shows a ''Cayo de Biscainhos'', the probable origin of the name for Key Biscayne.

Bill Baggs Cape Florida State Park
Bill Baggs Cape Florida State Recreation Area occupies approximately the southern third of the island of Key Biscayne, at coordinates . This park includes the Cape Florida Light, the oldest standing structure in Greater Miami. In 2005, it was ranked as having the 8th best beach in the country, and in 2013 ''Forbes'' ranked it at 7th. The park was named in honor of Bill Baggs, editor of ''The Miami News'' from 1957 until his death in 1969. He worked to protect the land from development and to preserve some of the key in its natural state. In 2004 a large historical marker was erected at the site to mark it as part of the National Underground Railroad Network to Freedom Trail, as hundreds of Black Seminoles, many fugitive slaves, escaped from here to freedom in the Bahamas, settling mostly on Andros Island. In the early 1820s, some 300 American slaves reached the Bahamas, aboard 27 sloops and many canoes. The US National Park Service is working with the Bahamas, particularly the A ...

Fowey Rocks Light
Fowey Rocks Light is located seven miles southeast of Cape Florida on Key Biscayne. The lighthouse was completed in 1878, replacing the Cape Florida Light. It was automated on May 7, 1975, and is still in operation. The structure is cast iron, with a screw-pile foundation, a platform and a skeletal tower. The light is 110 feet above the water. The tower framework is painted brown, while the dwelling and enclosed circular stair to the lantern is painted white. The original lens was a first-order drum Fresnel lens which stood about high and weighed about a ton (tonne). The light has a nominal range of 15 miles in the white sectors, and 10 miles in the red sectors. Fowey Rocks are named after the Royal Navy frigate HMS ''Fowey'' which was wrecked on a different reef to the south in 1748. During construction of the lighthouse the workers lived on a platform built over the water to minimize the danger of transporting them and their supplies each day from the mainland. While constru ...

Sand Bar
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
