ÃŽle Amsterdam
Île Amsterdam (), also known as Amsterdam Island and New Amsterdam (''Nouvelle-Amsterdam''), is an island of the French Southern and Antarctic Lands in the southern Indian Ocean that together with neighbouring Île Saint-Paul to the south forms one of the five districts of the territory. The island is roughly equidistant to the land masses of Madagascar, Australia, and Antarctica – as well as the British Indian Ocean Territory and the Cocos (Keeling) Islands (about from each). The research station at Martin-de-Viviès, first called ''Camp Heurtin'' and then ''La Roche Godon'', is the only settlement on the island and is the seasonal home to about thirty researchers and staff studying biology, meteorology, and geomagnetics. History The first person known to have sighted the island was the Spanish explorer Juan Sebastián de Elcano, on 18 March 1522, during his circumnavigation of the world. Elcano did not give the island a name. On 17 June 1633, Dutch mariner Anthonie va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Southern And Antarctic Lands
The French Southern and Antarctic Lands (french: Terres australes et antarctiques françaises, TAAF) is an Overseas Territory (french: Territoire d'outre-mer or ) of France. It consists of: # Adélie Land (), the French claim on the continent of Antarctica. # Crozet Islands (), a group in the southern Indian Ocean, south of Madagascar. # Kerguelen Islands (), a group of volcanic islands in the southern Indian Ocean, southeast of Africa. # Saint Paul and Amsterdam Islands (), a group to the north of the Kerguelen Islands. # The Scattered Islands (), a dispersed group of islands around the coast of Madagascar. The territory is sometimes referred to as the French Southern Lands (french: Terres australes françaises) or the French Southern Territories, usually to emphasize non-recognition of French sovereignty over Adélie Land as part of the Antarctic Treaty System. The entire territory has no permanently settled inhabitants. Approximately 150 (in the winter) to 310 (in the summ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumnavigation
Circumnavigation is the complete navigation around an entire island, continent, or astronomical object, astronomical body (e.g. a planet or natural satellite, moon). This article focuses on the circumnavigation of Earth. The first recorded circumnavigation of the Earth was the Magellan's circumnavigation, Magellan–Elcano expedition, which sailed from Sanlucar de Barrameda, Spain in 1519 and returned in 1522, after crossing the Atlantic Ocean, Atlantic, Pacific Ocean, Pacific, and Indian Ocean, Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth is straightforward, usually taking days instead of years. Today, the challenge of circumnavigating Earth has shifted towards human and technological endurance, speed, and List of circumnavigations#Miscellaneous, less conventional methods. Etymology The word ''circumnavigation'' is a noun formed from the verb ''circumnavigate'', from the past participle of the Latin verb '':wikt:circumnav ...

DXCC
An amateur radio operating award is earned by an amateur radio operator for establishing two-way communication (or "working") with other amateur radio stations. Awards are sponsored by national amateur radio societies, radio enthusiast magazines, or amateur radio clubs, and aim to promote activity on the amateur radio bands. Each award has its own set of rules and fees. Some awards require the amateur radio operator to have contacted other stations in a certain number of countries, Maidenhead grid locators, or counties. Because amateur radio operators are forbidden by regulation to accept financial compensation for their on-air activity, award recipients generally only receive a certificate, wooden plaque, or a small trophy as recognition of their award. Most amateur radio operating awards require that the applicant submit proof, such as QSL cards, of the contacts which satisfy the requirements of the award. There are thousands of operating awards available. The most popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callsign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi station ...

Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...

French Madagascar
The Colony of Madagascar and Dependencies (french: Colonie de Madagascar et dépendances) was a French colony off the coast of Southeast Africa between 1897 and 1958 in what is now Madagascar. The colony was formerly a protectorate of France known as Malagasy Protectorate. The protectorate became a colony, following Queen Ranavalona III's exile to island of Réunion. In 1958, the colonial administration in Madagascar was abolished, and it became autonomous territory of the French Community as the Malagasy Republic, which existed until 1975. History Background and French protectorate The United Kingdom had been an ally of Madagascar. In May 1862, John Russell, 1st Earl Russell, Britain's foreign secretary instructed Connolly Pakenham that Radama II should keep the country away from foreign powers. In 1882, the French started to occupy much of Madagascar's northern and western territories. In 1883, the Franco-Hova Wars commenced between France and Merina Kingdom, the war r ...

John Balleny
John Balleny (died 1857) was the English captain of the sealing schooner , who led an exploration cruise for the English whaling firm Samuel Enderby & Sons to the Antarctic in 1838–1839. During the expedition of 1838–1839, Balleny, sailing in company with Thomas Freeman and , sailed into the Southern Ocean along a corridor of longitude centering on the line of 175°E., south of New Zealand.

Schooner
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for priv ...

Barque
A barque, barc, or bark is a type of sailing ship, sailing vessel with three or more mast (sailing), masts having the fore- and mainmasts Square rig, rigged square and only the mizzen (the aftmost mast) Fore-and-aft rig, rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above. Etymology The word "barque" entered English via the French term, which in turn came from the Latin language, Latin ''barca'' by way of Occitan language, Occitan, Catalan language, Catalan, Spanish, or Italian. The Latin ''barca'' may stem from Celtic language, Celtic ''barc'' (per Rudolf Thurneysen, Thurneysen) or Greek ''baris'' (per Friedrich Christian Diez, Diez), a term for an Egyptian boat. The ''Oxford English Dictionary'', however, considers the latter improbable. The word ''barc'' appears to have come from Celtic languages. The form adopted by English, perhaps from Irish language, Irish, was "bark", while that adopted by Latin as ''barca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macartney Mission
The Macartney Embassy (), also called the Macartney Mission, was the first British diplomatic mission to China, which took place in 1793. It is named for its leader, George Macartney, Great Britain's first envoy to China. The goals of the mission included the opening of new ports for British trade in China, the establishment of a permanent embassy in Beijing, the cession of a small island for British use along China's coast, and the relaxation of trade restrictions on British merchants in Guangzhou (Canton). Macartney's delegation met with the Qianlong Emperor, who rejected all of the British requests. Although the mission failed to achieve its official objectives, it was later noted for the extensive cultural, political, and geographical observations its participants recorded in China and brought back to Europe. Background Foreign maritime trade in China was regulated through the Canton System, which emerged gradually through a series of imperial edicts in the 17th and 18th ce ...
