UKHO
The United Kingdom Hydrographic Office (UKHO) is the UK's agency for providing hydrographic and marine geospatial data to mariners and maritime organisations across the world. The UKHO is a trading fund of the Ministry of Defence (MoD) and is located in Taunton, Somerset, with a workforce of approximately 900 staff. The UKHO is responsible for operational support to the Royal Navy and other defence customers. Supplying defence and the commercial shipping industry, they help ensure Safety of Life at Sea (SOLAS), protect the marine environment and support the efficiency of global trade. Together with other national hydrographic offices and the International Hydrographic Organization (IHO), the UKHO works to set and raise global standards of hydrography, cartography and navigation. The UKHO also produces a commercial portfolio of ADMIRALTY Maritime Data Solutions, providing SOLAS-compliant charts, publications and digital services for ships trading internationally.

Admiralty Chart
Admiralty charts are nautical charts issued by the United Kingdom Hydrographic Office (UKHO) and subject to Crown Copyright. Over 3,500 Standard Nautical Charts (SNCs) and 14,000 Electronic Navigational Charts (ENCs) are available with the Admiralty portfolio offering the widest official coverage of international shipping routes and ports, in varying detail. Admiralty charts have been produced by UKHO for over 200 years, with the primary aim of saving and protecting lives at sea. The core market for these charts includes over 40,000 defence and merchant ships globally. Today, their products are used by over 90% of ships trading internationally. History The British admiralty charts are compiled, drawn and issued by the Hydrographic Office. This department of the Admiralty was established under Earl Spencer by an order in council in 1795, consisting of the Hydrographer, Alexander Dalrymple, one assistant and a draughtsman. The initial remit was to organise the cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrographer Of The Navy
The Hydrographer of the Navy is the principal hydrographical Royal Naval appointment. From 1795 until 2001, the post was responsible for the production of charts for the Royal Navy, and around this post grew the United Kingdom Hydrographic Office (UKHO). In 2001, the post was disassociated from UKHO, and the Hydrographer of the Navy is now a title bestowed upon the current captain—hydrography and meteorology—on the staff of the Devonport Flotilla at HMNB Devonport. History Before the establishment of the post, captains of Royal Navy ships were responsible for the provision of their own charts. In practice this meant that ships often sailed with inadequate information for safe navigation, and that when new areas were surveyed, the data rarely reached all those who needed it. The Admiralty appointed Alexander Dalrymple as hydrographer on 12 August 1795, with a remit to gather and distribute charts to HM Ships. Within a year existing charts had been collated, and the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taunton
Taunton () is the county town of Somerset, England, with a 2011 population of 69,570. Its thousand-year history includes a 10th-century monastic foundation, Taunton Castle, which later became a priory. The Normans built a castle owned by the Bishops of Winchester. Parts of the inner ward house were turned into the Museum of Somerset and Somerset Military Museum. For the Second Cornish uprising of 1497, Perkin Warbeck brought an army of 6,000; most surrendered to Henry VII on 4 October 1497. On 20 June 1685 the Duke of Monmouth crowned himself King of England here in a rebellion, defeated at the Battle of Sedgemoor. Judge Jeffreys led the Bloody Assizes in the Castle's Great Hall. The Grand Western Canal reached Taunton in 1839 and the Bristol and Exeter Railway in 1842. Today it hosts Musgrove Park Hospital, Somerset County Cricket Club, is the base of 40 Commando, Royal Marines, and is home to the United Kingdom Hydrographic Office on Admiralty Way.

Hydrography
Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defense, scientific research, and environmental protection. History The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the private property, even closely held secrets, of individuals who used them for commercial or military advantage. As transoceanic trade and exploration increased, hydrographic surveys started to be carried out as an exercise in their own right, and the commissioning of surveys was increasingly done by governments and special hydrographic offices. National organizations, particularly navies, realized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ministry Of Defence (United Kingdom)
The Ministry of Defence (MOD or MoD) is the department responsible for implementing the defence policy set by His Majesty's Government, and is the headquarters of the British Armed Forces. The MOD states that its principal objectives are to defend the United Kingdom of Great Britain and Northern Ireland and its interests and to strengthen international peace and stability. The MOD also manages day-to-day running of the armed forces, contingency planning and defence procurement. The expenditure, administration and policy of the MOD are scrutinised by the Defence Select Committee, except for Defence Intelligence which instead falls under the Intelligence and Security Committee of Parliament. History During the 1920s and 1930s, British civil servants and politicians, looking back at the performance of the state during the First World War, concluded that there was a need for greater co-ordination between the three services that made up the armed forces of the United Kingdom: t ...

Notice To Mariners
A notice to mariners (NTM or NOTMAR,) advises mariners of important matters affecting navigational safety, including new hydrographic information, changes in channels and aids to navigation, and other important data. Over 60 countries which produce nautical charts also produce a notice to mariners. About one third of these are weekly, another third are bi-monthly or monthly, and the rest irregularly issued according to need. For example, the United Kingdom Hydrographic Office issues weekly updates. United States The U.S. ''Notice to Mariners'' is made available weekly by the National Geospatial-Intelligence Agency (NGA), prepared jointly with the National Ocean Service (NOS) and the U.S. Coast Guard. The information in the ''Notice to Mariners'' is formatted to simplify the correction of paper charts, ''List of Lights'', ''Light Lists'', ''United States Coast Pilots'', and other publications produced by NGA, NOS, and the U.S. Coast Guard. Information for the ''Notice to Mariner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tierra Del Fuego
Tierra del Fuego (, ; Spanish for "Land of the Fire", rarely also Fireland in English) is an archipelago off the southernmost tip of the South American mainland, across the Strait of Magellan. The archipelago consists of the main island, Isla Grande de Tierra del Fuego, with an area of , and a group of many islands, including Cape Horn and Diego Ramírez Islands. Tierra del Fuego is divided between Chile and Argentina, with the latter controlling the eastern half of the main island and the former the western half plus the islands south of Beagle Channel and the southernmost islands. The southernmost extent of the archipelago is just north of latitude 56°S. The earliest known human settlement in Tierra del Fuego dates to approximately 8,000 BC. Europeans first explored the islands during Ferdinand Magellan's expedition of 1520. ''Tierra del Fuego'' and similar namings stem from sightings of the many bonfires that the natives built. Settlement by those of European descent and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tide Table
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal curve for the location. Tide levels are typically given relative to a low-water vertical datum, e.g. the mean lower low water (MLLW) datum in the US. NOAA Special Publication NOS CO-OPS 1, Silver Spring MD, June 2000. Publication and scope Tide tables are published in various forms, such as paper-based tables and tables available on the Internet. Most tide tables are calculated and published only for ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaufort Scale
The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. History The scale was devised in 1805 by the Irish hydrographer Francis Beaufort (later Rear Admiral), a Royal Navy officer, while serving on . The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before) to when Beaufort was Hydrographer of the Navy in the 1830s, when it was adopted officially and first used during the voyage of HMS ''Beagle'' under Captain Robert FitzRoy, who was later to set up the first Meteorological Office (Met Office) in Britain giving regular weather forecasts. In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective – one man's "stiff breeze" might be another's "soft breeze". Beaufort succeeded in standardising the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Francis grew up in Wales and Ireland until age fourteen. He left school and went to sea, but never stopped his education. By later in life, he had become sufficiently self ...

National Maritime Museum
The National Maritime Museum (NMM) is a maritime museum in Greenwich, London. It is part of Royal Museums Greenwich, a network of museums in the Maritime Greenwich World Heritage Site. Like other publicly funded national museums in the United Kingdom, it has no general admission charge; there are admission charges for most side-gallery temporary exhibitions, usually supplemented by many loaned works from other museums. Creation and official opening The museum was created by the National Maritime Museum Act 1934 under a Board of Trustees, appointed by HM Treasury. It is based on the generous donations of Sir James Caird (1864–1954). King George VI formally opened the museum on 27 April 1937 when his daughter Princess Elizabeth accompanied him for the journey along the Thames from London. The first director was Sir Geoffrey Callender. Collection Since the earliest times Greenwich has had associations with the sea and navigation. It was a landing place for the Romans, Henry ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
