HMS Shearwater (1837)
HMS ''Shearwater'' was a wooden paddle steamer which became the main surveying vessel in the UK in the 1840s. ''Shearwater'' was built in Harwich in 1826 for the Post Office, transferred to the Royal Navy in 1837, and equipped for surveying at Woolwich in 1841. Her length was 137', beam 23'. The first task, under the command of Captain John Washington, was to complete the great survey of the North Sea which had occupied Captain William Hewett for 10 years until the loss of his ship HMS ''Fairy'' with all hands in 1840. While in the North Sea, Washington also continued Hewett's work on tidal observations, verifying the theory of William Whewell that there should be a point in the southern North sea where there is no tidal rise or fall - what is now called an Amphidromic point. Captain Charles Robinson took command of ''Shearwater'' in January 1842, and carried out surveying work, mostly in western Scotland, until 1847. ''Shearwater'', along with other surveying boats was then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the propeller, screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. 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 superior ...

John Washington (Royal Navy Officer)
John Washington (1 January 1800 – 16 September 1863) was an officer of the Royal Navy, Hydrographer of the Navy, and a founding member of the Royal Geographical Society of London. Early career Washington joined the Royal Navy in May 1812, and served aboard with Sir George Cockburn's fleet in Chesapeake Bay, seeing much action in the War of 1812. From October 1813, he was aboard , which was sent to cruise off Greenland in 1814. On this voyage, he learnt much about astronomical and magnetic observations from the Master of the ship, William Bain (Later Sir William). He joined the Royal Naval Academy in November 1814, and graduated in May 1816. He then served for three years aboard on the North American Station, and afterwards as midshipman aboard and on the South American Station. He was promoted to lieutenant on 1 January 1821, while based at Valparaíso. He obtained permission to return to England by his own route, and took the track later followed b ...

North Sea
The North Sea lies between Great Britain, Denmark, Norway, Germany, the Netherlands, Belgium, and France. A sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind energy, wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Viking Age, Vikings' rise. The Hanseatic League, the Dutch Golden Age, Dutch Republic, and Kingdom of Great Britain, Brita ...

William Hewett (died 1840)
William Hewett was a Royal Navy officer noted for making the first comprehensive survey of the North Sea and for his work on tides. Hewett went to sea in first in the war with France, from 1805 to 1811, and in China in 1811. He then joined as midshipman. From 1813 he served in , and carried out a number of surveys on the coast of Brazil, including Maranhão, Ceará and Bahia. He was made an acting Lieutenant in 1814, which was confirmed in 1815. Hewett's first command was the surveying vessel HMS ''Protector''. From 1818 to 1830 he carried out surveys of the east coast of England, an area noted for dangerous and often shifting shoals. Hewett's description of the Leman and Ower banks, off the coast of Norfolk is given in full in the North Sea Sailing Directions of 1846. Other areas surveyed included Yarmouth Roads, the entrance to the Humber estuary, Lynn and Boston Deeps, The Gabbards and the Dudgeon. He also made recommendations for improvement of navigation of the coast, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Whewell
William Whewell ( ; 24 May 17946 March 1866) was an English polymath. He was Master of Trinity College, Cambridge. In his time as a student there, he achieved distinction in both poetry and mathematics. The breadth of Whewell's endeavours is his most remarkable feature. In a time of increasing specialisation, Whewell belonged in an earlier era when natural philosophers investigated widely. He published work in mechanics, physics, geology, astronomy, and economics, while also composing poetry, writing a Bridgewater Treatise, translating the works of Goethe, and writing sermons and Theology, theological tracts. In mathematics, Whewell introduced what is now called the Whewell equation, defining the shape of a curve without reference to an arbitrarily chosen coordinate system. He also organized thousands of volunteers internationally to study ocean tides, in what is now considered one of the first citizen science projects. He received the Royal Medal for this work in 1837.

Amphidromic Point
An amphidromic point, also called a tidal node, is a geographical location where there is little or no difference in sea height between high tide and low tide; it has zero tidal amplitude for one harmonic constituent of the tide. The tidal range (the peak-to-peak amplitude, or the height difference between high tide and low tide) for that harmonic constituent increases with distance from this point, though not uniformly. As such, the concept of amphidromic points is crucial to understanding tidal behaviour. The term derives from the Greek words ''amphi'' ("around") and ''dromos'' ("running"), referring to the rotary tides which circulate around amphidromic points. It was first discovered by William Whewell, who extrapolated the cotidal lines from the coast of the North Sea and found that the lines must meet at some point. Amphidromic points occur because interference within oceanic basins, seas and bays, combined with the Coriolis effect, creates a wave pattern — call ...

Charles Gepp Robinson
Charles Gepp Robinson (3 December 1805 – 31 October 1875) was a Royal Navy Officer and hydrographic surveyor particularly noted for his survey work in the west of Scotland. Robinson was born at Appledore House in Devon. He joined the Navy on 13 May 1819 on board HMS ''Hasty'' in the North Sea. His first overseas posting was with William Fitzwilliam Owen in from 1821-1826, surveying the east coast of Africa. The survey cost the lives of more than half of the crew due to tropical diseases, and Robinson was one of the few officers to return alive to England. He was promoted to Lieutenant in 1826, and returned to Africa with Owen in HMS ''Eden'' on a mission to establish a settlement at Fernando Po, which was believed to be healthier than other parts of West Africa. This turned out not to be true, and mortality due to fever was as high as on the previous trip, but again Robinson was one of the few to survive, as did Owen and his family who accompanied him. During his time in Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paddle Steamers Of The United Kingdom
A paddle is a handheld tool with an elongated handle and a flat, widened end (the ''blade'') used as a lever to apply force onto the bladed end. It most commonly describes a completely handheld tool used to propel a human-powered watercraft by pushing water in a direction opposite to the direction of travel (i.e. paddling). A paddle is different from an oar (which can be similar in shape and perform the same function via rowing) – an oar is attached to the watercraft via a fulcrum. The term "paddle" can also be used to describe objects of similar shapes or functions: *A rotating set of paddle boards known as a paddle wheel is used to propel a steamboat or paddle steamer. *In a number of racquet sports (e.g. ping-pong and paddle ball), a "paddle" or "bat" is a short, solid racket used to strike a ball. *A mixing paddle is a device used to stir or mix separate ingredients within a mixture. *A spanking paddle is used in corporal punishment, typically to forcefully hit someone ...
