Given the question: Information:  - A "metropolitan area", sometimes referred to as a "metro area" or just "metro", is a region consisting of a densely populated urban core and its less-populated surrounding territories, sharing industry, infrastructure, and housing. A metro area usually comprises multiple jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas include one or more urban areas, as well as satellite cities, towns and intervening rural areas that are socio-economically tied to the urban core, typically measured by commuting patterns.  - Alabama is a state in the southeastern region of the United States. It is bordered by Tennessee to the north, Georgia to the east, Florida and the Gulf of Mexico to the south, and Mississippi to the west. Alabama is the 30th-most extensive and the 24th-most populous of the U.S. states. At nearly , Alabama has one of the nation's longest navigable inland waterways.  - The Straits of Florida, Florida Straits, or Florida Strait is a strait located south-southeast of the North American mainland, generally accepted to be between the Gulf of Mexico and the Atlantic Ocean, and between the Florida Keys (U.S.) and Cuba. It is 150 km (93 mi) wide at the narrowest point between Key West and the Cuban shore, and has been sounded to a depth of 6,000 feet. The strait carries the Florida Current, the beginning of the Gulf Stream, from the Gulf of Mexico.  - South Florida is a region of the U.S. state of Florida, comprising the southernmost part of the state. It is one of Florida's three most common "directional" regions, the others being Central Florida and North Florida. It includes the populous Miami metropolitan area, the Florida Keys, and other localities. South Florida is the only part of the continental United States with a tropical climate.  - Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean meet. It is south of both the U.S. state of Florida and the Bahamas, west of Haiti, and north of Jamaica. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. Cuba is the largest island in the Caribbean, with an area of , and the second-most populous after Hispaniola, with over 11 million inhabitants.  - The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World".  - A drainage basin or catchment basin is an extent or an area of land where all surface water from rain, melting snow, or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another body of water, such as a river, lake, reservoir, estuary, wetland, sea, or ocean. Thus if a tributary stream joins a brook that in turn joins a small river which is a tributary of a larger river, there is a series of successively larger (and lower elevation) drainage basins. For instance, the Missouri and Ohio rivers are within their own drainage basins and also within the drainage basin of the Mississippi River.  - A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.  - The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, which are often referred to as the "Third Coast" in comparison with the U.S. Atlantic and Pacific coasts, or sometimes the "south coast", in juxtaposition to the Great Lakes region being the "north coast." One of the gulf's seven main areas is the Gulf of Mexico basin.  - A skyscraper is a tall, continuously habitable building having multiple floors. When the term was originally used in the 1880s it described a building of 10 to 20 floors but now describes one of at least 40-50 floors. Mostly designed for office, commercial and residential uses a skyscraper can also be called a high-rise, but the term skyscraper is often used for buildings higher than . For buildings above a height of , the term "Supertall" can be used, while skyscrapers reaching beyond are classified as "Megatall".  - Biscayne Bay ("Bahía Vizcaína" in Spanish) is a lagoon that is approximately long and up to wide located on the Atlantic coast of South Florida, United States.
