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. The lagoon was known as "Key Biscayne B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Downtown Miami
Downtown Miami is the urban city center of Miami, Florida. The city's greater downtown region consists of the Central Business District, Brickell, the Historic District, Government Center, the Arts & Entertainment District, and Park West. It is divided by the Miami River and is bordered by Midtown Miami's Edgewater and Wynwood sections to its north, Biscayne Bay to its east, the Health District and Overtown to its west, and Coconut Grove to its south. Downtown Miami is the core of the Miami metropolitan area, the nation's ninth largest and world's 34th largest metropolitan area with a population of 6.158 million people. Within Downtown Miami, Brickell Avenue and Biscayne Boulevard are the main north–south roads, and Flagler Street is the main east–west road. The Downtown Miami perimeters are defined by the Miami Downtown Development Authority as the area east of Interstate 95 between Rickenbacker Causeway to the south and the Julia Tuttle Causeway, which connects ...

Florida Keys
The Florida Keys are a coral cay archipelago located off the southern coast of Florida, forming the southernmost part of the continental United States. They begin at the southeastern coast of the Florida peninsula, about south of Miami, and extend in a gentle arc south-southwest and then westward to Key West, the westernmost of the inhabited islands, and on to the uninhabited Dry Tortugas. The islands lie along the Florida Straits, dividing the Atlantic Ocean to the east from the Gulf of Mexico to the northwest, and defining one edge of Florida Bay. At the nearest point, the southern part of Key West is just from Cuba. The Florida Keys are between about 24.3 and 25.5 degrees North latitude. More than 95 percent of the land area lies in Monroe County, but a small portion extends northeast into Miami-Dade County, such as Totten Key. The total land area is . As of the 2010 census the population was 73,090 with an average density of , although much of the population is concent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miami River (Florida)
The Miami River is a river in the United States state of Florida that drains out of the Everglades and runs through the city of Miami, including Downtown. The long river flows from the terminus of the Miami Canal at Miami International Airport to Biscayne Bay. It was originally a natural river inhabited at its mouth by the Tequesta Indians, but it was dredged and is now polluted throughout its route through Miami-Dade County. The mouth of the river is home to the Port of Miami and many other businesses whose pressure to maintain it has helped to improve the river's condition. Etymology Although it is widely believed that the name is derived from a Native American word that means "sweet water," the earliest mention of the name comes from Hernando de Escalante Fontaneda, a captive of Indians in southern Florida for 17 years, when he referred to what is now Lake Okeechobee as the "Lake of Mayaimi, which is called Mayaimi because it is very large". The Mayaimi people were n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Key Largo Limestone
The Key Largo Limestone is a geologic formation in Florida. It is a fossilized coral reef. The formation is exposed along the upper and middle Florida Keys from Soldier Key (at the north end of the Florida Keys) to the Bahia Honda Channel (at the west end of Bahia Honda Key). The islands form a long narrow arc concentric with the inner edge of the Florida Straits and with the Florida Reef. The limestone includes fossils of corals, mollusks and bryozoans. Fossilized coral head formations are visible in some exposures. The Key Largo Limestone continues in a narrow band underwater just offshore of the coast of Florida north of Soldier Key to the middle of the Palm Beach County coast, and southward just offshore of the lower Florida Keys to the Dry Tortugas.

Wisconsin Glaciation
The Wisconsin Glacial Episode, also called the Wisconsin glaciation, was the most recent glacial period of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from approximately 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation radically altered the ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

Jewfish Creek Bridge
The Jewfish Creek Bridge is a beam bridge in the Florida Keys. Spanning both Jewfish Creek and Lake Surprise, it carries the Overseas Highway ( U.S. Route 1) between the Florida Keys and the Florida mainland. The bridge is tall and opened in 2008, replacing a small drawbridge. History The original Jewfish Creek beam bridge opened for traffic in 1944 along with the current stretch of the Overseas Highway between Florida City and Key Largo (locally known as the 18 Mile Stretch). Prior to this, the Overseas Highway was connected to the mainland via the nearby Card Sound Bridge (which at the time was also a small drawbridge). The current route was built along the original right of way of the Overseas Railroad, which shortened the driving distance between Florida City and Key Largo by nearly . The United States Navy, which continues to have a large presence in Key West, sought an improved access to the mainland during World War II, which is the reason the Overseas Highway ...

Shoal
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 refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrier Island
Barrier islands are coastal landforms and a type of Dune, dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend uninterrupted for over a hundred kilometers, excepting the tidal inlets that separate the islands, the longest and widest being Padre Island of Texas, United States. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, Sediment transport, sediment supply, Sea leve ...

Key Largo
Key Largo ( es, Cayo Largo) is an island in the upper Florida Keys archipelago and is the largest section of the keys, at long. It is one of the northernmost of the Florida Keys in Monroe County, and the northernmost of the keys connected by U.S. Highway 1 (the Overseas Highway). Three census-designated places are on the island of Key Largo: North Key Largo, near the Card Sound Bridge, Key Largo, eight to nine miles from the southern end of the island, and Tavernier, at the southern end of the island. As of 2010, the three places have a combined population of 13,850. None of Key Largo is an incorporated municipality, so it is governed at the local level by Monroe County. Key Largo is connected to the mainland in Miami-Dade County by two routes. The first route is the Overseas Highway, the southernmost portion of U.S. Highway 1, which enters Key Largo at Jewfish Creek near the middle of the island and turns southwest. The second route is Card Sound Road, which connects to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
