Sombrero Island
Sombrero, also known as Hat Island, is part of the British Overseas Territory of Anguilla and is the northernmost island of the Lesser Antilles. It lies north-west of Anguilla across the Dog and Prickly Pear Passage. The distance to Dog Island, the next nearest island of Anguilla, is . Sombrero is long north–south, and wide. The land area is . Originally, when viewed from the sea, the island had the shape of a sombrero hat, but guano-mining operations have left the island with precipitous sides and a relatively flat top that is above sea level. The surface of the island is rough, and vegetation is sparse. The guano-mining operation yielded some 3000 tons of phosphate a year by 1870. By 1890, the phosphate reserves had been exhausted. History As a result of the Treaty of Utrecht in 1714, Sombrero passed into the hands of the British. Captain Warwick Lake of ''Recruit'' marooned an impressed seaman, Robert Jeffrey, there on 13 December 1807. As it turned out, Jeffre ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Marooning
Marooning is the intentional act of abandoning someone in an uninhabited area, such as a desert island, or more generally (usually in passive voice) to be marooned is to be in a place from which one cannot escape. The word is attested in 1699, and is derived from the term maroon, a word for a fugitive slave, which could be a corruption of Spanish '' cimarrón'' (rendered as "symeron" in 16th–17th century English), meaning a household animal (or slave) who has "run wild". ''Cimarrón'' in turn may be derived from the Taino word ''símaran'' (“wild”) (like a stray arrow), from ''símara'' (“arrow”). The practice was a penalty for crewmen, or for captains at the hands of a crew in cases of mutiny. Generally, a marooned man was set on a deserted island, often no more than a sand bar at low tide. He would be given some food, a container of water, and a loaded pistol so he could die by suicide if he desired. The outcome of marooning was usually fatal, but survival was possib ...

Thames Ironworks And Shipbuilding Company

Its main activity was shipbuilding, but it also diversified into civil engineering, marine engines, cranes, electrical engineering and motor cars.Jim Lewis 1999, ''London's Lea Valley'', Phillimore, The company notably produced iron work for Isambard Kingdom Brunel's Royal Albert Bridge over the Tamar in the 1850s, and the world's first all-iron warship, HMS ''Warrior'', launched in 1860. History 1837–46 The company originated in 1837 as the Ditchburn and Mare Shipbuilding Company, founded by shipwright Thomas J. Ditchburn and the engineer and naval architect Charles John Mare.

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), 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 the advent of much cheaper, more sophisticated, and more 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 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 and promontory, prom ...

Anegada Island
Anegada is the northernmost of the British Virgin Islands (BVI), a group of islands that form part of the archipelago of the Virgin Islands. It lies about north of Virgin Gorda. Anegada is the only inhabited British Virgin Island formed from coral and limestone, rather than of volcanic origin. While the other islands are mountainous, Anegada is flat and low. Its highest point is only about above sea level, earning it its name, which is from the Spanish for "flooded land", ''tierra anegada''. Additionally, Anegada is the only sliver of land directly south of Bermuda, another British overseas territory. Anegada lies directly west of Mauritania in Africa and east of all other islands in the British Virgin Islands. At about 15 square miles (38 square kilometers), Anegada is the second-largest of the British Virgin Islands. With a population of 450 as of the 2024 census. Most of Anegada's residents live in the only village, The Settlement. Economy The primary business of Ane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Mail Steam Packet Company
The Royal Mail Steam Packet Company was a British shipping company founded in London in 1839 by a Scot, James MacQueen. The line's motto was ''Per Mare Ubique'' (everywhere by sea). After a troubled start, it became the largest shipping group in the world in 1927 when it took over the White Star Line. The company was liquidated and its assets taken over by the newly formed Royal Mail Lines in 1932 after financial trouble and scandal; over the years RML declined to no more than the name of a service run by former rival Hamburg Süd. History as Royal Mail Steam Packet Company The RMSPC, founded in 1839 by James MacQueen, ran tours and mail to various destinations in the Caribbean and South America, and by 1927, was the largest shipping group in the world. MacQueen’s imperial visions for the RMSPC were clear; he hoped that new steamship communications between Britain and the Caribbean would mitigate post-Emancipation instabilities, in particular by promoting commerce.

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Phosphate
Phosphates are the naturally occurring form of the element phosphorus. In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, phosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one proton gives the dihydrogen phosphate ion while removal of two protons gives the hydrogen phosphate ion . These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.
