Alonso Álvarez de Pineda (Spanish:; 1494–1520) was a Spanish conquistador and cartographer who was the first to prove the insularity of the Gulf of Mexico by sailing around its coast. In doing so he created the first map to depict what is now Texas and parts of the Gulf Coast of the United States.
As large parts of the Florida coast remained unprotected by lighthouses until late in the 19th century, ships frequently wrecked along coast, particularly along the Florida Keys, where for a while wrecking made Key West the largest and richest city in Florida. The U.S. Navy has played a prominent role in Florida's maritime history. In the 1820s ...
Galileo's discovery had practical applications. Safe navigation required accurately determining a ship's position at sea. While latitude could be measured well enough by local astronomical observations, determining longitude required knowledge of the time of each observation synchronized to the time at a reference longitude.
The focus of this extended mission was to follow up on the discoveries made at Europa with seven additional flybys to search for new evidence of a possible sub-surface water ocean. [21] Starting in May 1999, Galileo used four flybys (20 to 23) with Callisto to lower its periapse, setting up a chance for it to fly by Io twice in late 1999. [2]
At 345 feet (105 m) above mean sea level, Britton Hill in northern Walton County is the highest point in Florida and the lowest known highpoint of any U.S. state. [3] Much of the state south of Orlando is low-lying and fairly level; however, some places, such as Clearwater, feature vistas that rise 50 to 100 feet (15 to 30 m) above the water.
The peninsular coast of the US state of Florida is formed from contact with three main large bodies of water: the open Atlantic Ocean to the east, the Caribbean Sea to the south, and the Gulf of Mexico to the West (making part of the larger Gulf Coast of the United States).
If the Galileo/IUS combination fell free from the orbiter at 27,000 meters (90,000 ft), the RTGs would fall to Earth without melting, and drop into the Atlantic Ocean about 240 kilometers (150 mi) from the Florida coast. On the other hand, if the orbiter broke up at an altitude of 98,700 meters (323,800 ft) it would be traveling at 2,425 meters ...
The Port of St. Petersburg opened in 1925 in anticipation of becoming a major shipping port. In the beginning, the port was used mainly for the use of the U.S. Coast Guard from 1927 up until it was abandoned in 1933, although the base was reopened in 1939 due to World War II. Following World War II, the port was used as a dry dock for ships. In ...
