Royal Geographical Society
The Royal Geographical Society (with the Institute of British Geographers), often shortened to RGS, is a learned society and professional body for geography based in the United Kingdom. Founded in 1830 for the advancement of geographical sciences, the Society has 16,000 members, with its work reaching the public through publications, research groups and lectures. The Society was founded in 1830 under the name ''Geographical Society of London'' as an institution to promote the 'advancement of geographical science'. It later absorbed the older African Association, which had been founded by Sir Joseph Banks in 1788, as well as the Raleigh Club and the Palestine Association. In 1995 it merged with the Institute of British Geographers, a body for academic geographers, to officially become the Royal Geographical Society ''with IBG''. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The member ...

Meridian Arc
In geodesy and navigation, a meridian arc is the curve between two points on the Earth's surface having the same longitude. The term may refer either to a segment of the meridian, or to its length. The purpose of measuring meridian arcs is to determine a figure of the Earth. One or more measurements of meridian arcs can be used to infer the shape of the reference ellipsoid that best approximates the geoid in the region of the measurements. Measurements of meridian arcs at several latitudes along many meridians around the world can be combined in order to approximate a ''geocentric ellipsoid'' intended to fit the entire world. The earliest determinations of the size of a spherical Earth required a single arc. Accurate survey work beginning in the 19th century required several arc measurements in the region the survey was to be conducted, leading to a proliferation of reference ellipsoids around the world. The latest determinations use astro-geodetic measurements and the method ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chronometer Watch
A chronometer (; Literally, a measurer of time) is an extraordinarily accurate timepiece, with an original focus on the needs of maritime navigation. In Switzerland, timepieces certified by the Contrôle Officiel Suisse des Chronomètres ( COSC) may be marked as ''Certified Chronometer'' or ''Officially Certified Chronometer''. Outside Switzerland, equivalent bodies, such as the Japan Chronometer Inspection Institute, have in the past certified timepieces to similar standards, although use of the term has not always been strictly controlled. History The term ''chronometer'' was coined by Jeremy Thacker of Beverley, England in 1714, referring to his invention of a clock ensconced in a vacuum chamber. The term ''chronometer'' is also used to describe a marine chronometer used for celestial navigation and determination of longitude. The marine chronometer was invented by John Harrison in 1730. This was the first of a series of chronometers that enabled accurate marine navigatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockall
Rockall () is an uninhabitable granite islet situated in the North Atlantic Ocean. The United Kingdom claims that Rockall lies within its exclusive economic zone (EEZ) and is part of its territory, but this claim is not recognised by Ireland. It and the nearby skerries of Hasselwood Rock and Helen's Reef are the only emergent parts of the Rockall Plateau. The rock was formed by magmatism as part of the North Atlantic Igneous Province during the Paleogene. Rockall's approximate distances from the closest islands in each direction are as follows: It is west of Soay, Scotland; northwest of Tory Island, Ireland; and south of Iceland. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, to the east. The United Kingdom claimed Rockall in 1955 and incorporated it as a part of Scotland in 1972. The UK does not make a claim to extended EEZ based on Rockall, as it has ratified the United Nations Convention on the Law of the Sea (U ...

Francis Beaufort
Rear-Admiral Sir Francis Beaufort (; 27 May 1774 – 17 December 1857) was an Irish hydrographer, rear admiral of the Royal Navy, and creator of the Beaufort cipher and the Beaufort scale. Early life Francis Beaufort was descended from French Protestant Huguenots, who fled the French Wars of Religion in the sixteenth century. His parents moved to Ireland from London. His father, Daniel Augustus Beaufort, was a Protestant clergyman from Navan, County Meath, Ireland, and a member of the learned Royal Irish Academy. His mother Mary was the daughter and co-heiress of William Waller, of Allenstown House. Francis was born in Navan on 27 May 1774. He had an older brother, William Louis Beaufort and three sisters, Frances, Harriet, and Louisa. His father created and published a new map of Ireland in 1792.

British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Gr ...

Post-captain
Post-captain is an obsolete alternative form of the rank of captain in the Royal Navy. The term served to distinguish those who were captains by rank from: * Officers in command of a naval vessel, who were (and still are) addressed as captain regardless of rank; * Commanders, who received the title of captain as a courtesy, whether they currently had a command or not (e.g. the fictional Captain Jack Aubrey in '' Master and Commander'' or the fictional Captain Horatio Hornblower in ''Hornblower and the Hotspur''); this custom is now defunct. In the Royal Navy of the 18th and 19th centuries, an officer might be promoted from commander to captain, but not have a command. Until the officer obtained a command, he was "on the beach" and on half-pay. An officer "took post" or was "made post" when he was first commissioned to command a vessel. Usually this was a rated vessel – that is, a ship too important to be commanded by a mere commander – but was occasionally an unrated one. ...

William Fitzwilliam Owen
Vice Admiral William Fitzwilliam Owen (17 September 1774 – 3 November 1857), was a British naval officer and explorer. He is best known for his exploration of the west and east African coasts, discovery of the Seaflower Channel off the coast of Sumatra and for surveying the Canadian Great Lakes. The illegitimate son of Captain William Owen he was orphaned at the age of four, however, his father's friend Rear-Admiral Sir Thomas Rich, kept an eye on both William and his elder brother Edward. In 1788 at age 13 he embarked as a midshipman in Rich's ship, , and from that time the Royal Navy was his life. Self-willed and boisterous, he had not infrequent difficulties early in his naval career. He served at home and on ships in the East Indies. He was commissioned as a lieutenant in 1797. In 1801 he took command of the fireship . In late 1801 the hired armed cutter ''King George'', under the command of a Mr. Yawkins, served under Nelson at his failed attack on Boulogne. On ...
