Calypso (ship)
Several vessels have been named ''Calypso'' for the figure from Greek mythology. * ''Calypso'' was a snow of 47 tons ( bm), built in Dublin in 1792. On 21 June 1796 she sailed, probably from Liverpool, as a slave ship in the triangular trade in enslaved people. "Renau's squadron" captured her on the Windward Coast of Africa; her master ransomed her. She then completed her voyage, arriving at Barbados on 1 June 1797 with 79 slaves. She then disappears from online records. * ''Calypso'', of 190 tons (bm), was built in Bermuda in 1795. The Sierra Leone Company purchased her circa 1796 to support their settlement in Sierra Leone. A French privateer under Spanish colours captured ''Calypso'', Cole, master, in February 1798 as ''Calypso'' was going down the Gold Coast from Sierra Leone. * is a former British Royal Navy minesweeper converted into a research vessel for the oceanographic researcher Jacques Cousteau, equipped with a mobile laboratory for underwater field research.

Calypso (mythology)
In Greek mythology, Calypso (; grc-gre, Καλυψώ, "she who conceals") was a nymph who lived on the island of Ogygia, where, according to Homer's ''Odyssey'', she detained Odysseus for seven years. She promised Odysseus immortality if he would stay with her, but Odysseus preferred to return home. Etymology The name "Calypso" may derive from the Ancient Greek (), meaning "to cover", "to conceal", or "to hide". According to ''Etymologicum Magnum'', her name means "concealing the knowledge" ( grc, καλύπτουσα το διανοούμενον, kalýptousa to dianooúmenon, label=none), which – combined with the Homeric epithet (, meaning "subtle" or "wily") – justifies the reclusive character of Calypso and her island. Family Calypso is generally said to be the daughter of the Titan Atlas. Her mother is mostly unnamed, but Hyginus wrote that it was Pleione, mother of the Pleiades. Hesiod, and the Homeric Hymn to Demeter, mention either a different Calypso o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow (ship)
In sailing, a snow, snaw or snauw is a square-rigged vessel with two masts, complemented by a snow- or trysail-mast stepped immediately abaft (behind) the main mast.Hans Haalmeijer (2009). Pinassen, fluiten en galjassen, the Netherlands: Uitgeverij De Alk B.V. History The word 'snow' comes from 'snauw', which is an old Dutch word for beak, a reference to the characteristic sharp bow of the vessel. The snow evolved from the (three-masted) ship: the mizzen mast of a ship was gradually moved closer towards the mainmast, until the mizzen mast was no longer a separate mast, but was instead made fast at the main mast top. As such, in the 17th century the snow used to be sometimes classified as a three-masted vessel. The snow dates back to the late 17th century and originally had a loose-footed gaff sail; the boom was introduced somewhere in the 18th century. It was a popular type of vessel in the Baltic Sea and was employed by a large number of nations during its time. The snow was ...

Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in feet, from the stem to the sternpost; * '' Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capacity in cubic feet, another method of volumetric measurem ...

Liverpool
Liverpool is a city and metropolitan borough in Merseyside, England. With a population of in 2019, it is the 10th largest English district by population and its metropolitan area is the fifth largest in the United Kingdom, with a population of 2.24 million. On the eastern side of the Mersey Estuary, Liverpool historically lay within the ancient hundred of West Derby in the county of Lancashire. It became a borough in 1207, a city in 1880, and a county borough independent of the newly-created Lancashire County Council in 1889. Its growth as a major port was paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, and raw materials such as coal and cotton, merchants were involved in the slave trade. In the 19th century, Liverpool was a major port of departure for English and Irish emigrants to North America. It was also home to both the Cunard and White Star Lines, and was the port of registry of the ocean lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slave Ship
Slave ships were large cargo ships specially built or converted from the 17th to the 19th century for transporting slaves. Such ships were also known as "Guineamen" because the trade involved human trafficking to and from the Guinea coast in West Africa. Atlantic slave trade In the early 1600s, more than a century after the arrival of Europeans to the Americas, demand for unpaid labor to work plantations made slave-trading a profitable business. The Atlantic slave trade peaked in the last two decades of the 18th century, during and following the Kongo Civil War. To ensure profitability, the owners of the ships divided their hulls into holds with little headroom, so they could transport as many slaves as possible. Unhygienic conditions, dehydration, dysentery and scurvy led to a high mortality rate, on average 15% and up to a third of captives. Often the ships carried hundreds of slaves, who were chained tightly to plank beds. For example, the slave ship ''Henrietta Ma ...

Triangular Trade
Triangular trade or triangle trade is trade between three ports or regions. Triangular trade usually evolves when a region has export commodities that are not required in the region from which its major imports come. It has been used to offset trade imbalances between different regions. The Atlantic slave trade used a system of three-way trans-Atlantic exchanges – known historically as the triangular trade – which operated between Europe, Africa and the Americas from the 16th to 19th centuries. A classic example is the colonial molasses trade, which involved the circuitous trading of slaves, sugar (often in liquid form, as molasses), and rum between West Africa, the West Indies and the northern colonies of British North America in the 17th and 18th centuries. The slaves grew the sugar that was used to brew rum, which in turn was traded for more slaves. In this circuit, the sea lane west from Africa to the West Indies (and later, also to Brazil) was known as the Middle Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windward Coast
The Windward Coast was used to describe an area of West Africa located on the coast between Cape Mount and Assini, i.e. the coastlines of the modern states of Liberia and Ivory Coast, to the west of what was called the Gold Coast. A related region was called the Pepper Coast or Grain Coast The Pepper Coast or Grain Coast was a coastal area of western Africa, between Cape Mesurado and Cape Palmas. It encloses the present republic of Liberia. The name was given by European traders. Origin of the name The Pepper Coast got its name f ....

Sierra Leone Company
The Sierra Leone Company was the corporate body involved in founding the second British colony in Africa on 11 March 1792 through the resettlement of Black Loyalists who had initially been settled in Nova Scotia (the Nova Scotian Settlers) after the American Revolutionary War. The company came about because of the work of the ardent abolitionists, Granville Sharp, Thomas Clarkson, Henry Thornton, and Thomas's brother, John Clarkson, who is considered one of the founding fathers of Sierra Leone. The company was the successor to the St. George Bay Company, a corporate body established in 1790 that re-established Granville Town in 1791 for the 60 remaining Old Settlers. St. George's Bay Company The Sierra Leone Company was the successor to the St. George's Bay Company that had been founded in 1790 following a mostly unsuccessful effort by the Committee for the Relief of the Black Poor in 1787 to establish a free settlement for the " Black Poor" of London, many of whom were Bla ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minesweeper
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear wa ...

Research Vessel
A research vessel (RV or R/V) is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters. History The research ship had origins in the early voyages of exploration. By the time of James Cook's ''Endeavour'', the essentials of what today we would call a research ship are clearly apparent. In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. The ''Endeavour'' was a sturdy vessel, well designed and equipped for the ordeals she would face, and fitted out with facilities for her "research personnel", Joseph Banks. As is common with contemporary research vessels, ''Endeavour'' also carried out more th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanography
Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology.
