Amateur Radio Lighthouse Society
Founded in 2000 by Jim Weidner, K2JXW, the Amateur Radio Lighthouse Society is devoted to maritime communications, amateur radio and lightships. Its members travel to lighthouses around the world where they operate amateur radio equipment at or near the light. Collecting lighthouse QSLs is popular for some amateur radio operators. ARLHS is a membership organization with over 1665 members worldwide as of July 2009. A convention is held in October each year. In 2010 the gathering was in Mississippi. In earlier years it has been held in Solomons, Maryland, St. Simons, Port Huron and other sites. Membership benefits include a newsletter, email reflector, awards program, lighthouse expedition sponsorship, embroidered shoulder patch, a list of every known light beacon in the world capable of supporting a ham station, a web site at; the ARLHS has been featured in national magazines, such as WordRadio. Jim Weidner is its founding President; the club call sign is W7QF and the website is The ARLHS maintains a catalog of lighthouses called The World List of Lights.
Its main feature is a short, transmitted identification number for each lighthouse. The WLOL lists any lighthouse, or was an Aid to Navigation and can reasonably accommodate an amateur radio operation. Lights that are no longer in existence, but were once an ATN show up on the list, designated as historical. With over 15,000 entries, the WLOL is one of the most complete lighthouse catalogs in existence.

National Geospatial-Intelligence Agency
The National Geospatial-Intelligence Agency is a combat support agency under the United States Department of Defense and a member of the United States Intelligence Community, with the primary mission of collecting and distributing geospatial intelligence in support of national security. NGA was known as the National Imagery and Mapping Agency until 2003. NGA headquarters known as NGA Campus East, is located at Fort Belvoir North Area in Virginia; the agency operates major facilities in the St. Louis, Missouri area, as well as support and liaison offices worldwide; the NGA headquarters, at 2.3 million square feet, is the third-largest government building in the Washington metropolitan area after The Pentagon and the Ronald Reagan Building. In addition to using GEOINT for U. S. military and intelligence efforts, the NGA provides assistance during natural and man-made disasters, security planning for major events such as the Olympic Games. In September 2018, researchers at the National Geospatial-Intelligence Agency released a high resolution terrain map of Antarctica, named the "Reference Elevation Model of Antarctica".
U. S. mapping and charting efforts remained unchanged until World War I, when aerial photography became a major contributor to battlefield intelligence. Using stereo viewers, photo-interpreters reviewed thousands of images. Many of these were of the same target at different angles and times, giving rise to what became modern imagery analysis and mapmaking; the Engineer Reproduction Plant was the Army Corps of Engineers's first attempt to centralize mapping production and distribution. It was located on the grounds of the Army War College in Washington, D. C. Topographic mapping had been a function of individual field engineer units using field surveying techniques or copying existing or captured products. In addition, ERP assumed the "supervision and maintenance" of the War Department Map Collection, effective April 1, 1939. With the advent of the Second World War aviation, field surveys began giving way to photogrammetry, photo interpretation, geodesy. During wartime, it became possible to compile maps with minimal field work.
Out of this emerged AMS, which absorbed the existing ERP in May 1942. It was located at the Dalecarlia Site on MacArthur Blvd. just outside Washington, D. C. in Montgomery County and adjacent to the Dalecarlia Reservoir. AMS was designated as an Engineer field activity, effective July 1, 1942, by General Order 22, OCE, June 19, 1942; the Army Map Service combined many of the Army's remaining geographic intelligence organizations and the Engineer Technical Intelligence Division. AMS was redesignated the U. S. Army Topographic Command on September 1, 1968, continued as an independent organization until 1972, when it was merged into the new Defense Mapping Agency and redesignated as the DMA Topographic Center; the agency's credit union, Constellation Federal Credit Union, was chartered during the Army Map Service era, in 1944. It has continued to serve all successive legacy their families. After the war, as airplane capacity and range improved, the need for charts grew; the Army Air Corps established its map unit, renamed ACP in 1943 and was located in St. Louis, Missouri.
ACP was known as the U. S. Air Force Aeronautical Chart and Information Center from 1952 to 1972. A credit union was chartered for the ACP in 1948, called Aero Chart Credit Union, it was renamed Arsenal Credit Union in 1952, a nod to the St. Louis site's Civil War-era use as an arsenal. Shortly before leaving office in January 1961, President Dwight D. Eisenhower authorized the creation of the National Photographic Interpretation Center, a joint project of the CIA and US DoD. NPIC was a component of the CIA's Directorate of Science and Technology and its primary function was imagery analysis. NPIC became part of the National Imagery and Mapping Agency in 1996. NPIC first identified the Soviet Union's basing of missiles in Cuba in 1962. By exploiting images from U-2 overflights and film from canisters ejected by orbiting Corona s, NPIC analysts developed the information necessary to inform U. S. influence operations during the Cuban Missile Crisis. Their analysis garnered worldwide attention when the Kennedy Administration declassified and made public a portion of the images depicting the Soviet missiles on Cuban soil.
The Defense Mapping Agency was created on January 1, 1972, to consolidate all U. S. military mapping activities. DMA's "birth certificate", DoD Directive 5105.40, resulted from a classified Presidential directive, "Organization and Management of the U. S. Foreign Intelligence Community", which directed the consolidation of mapping functions dispersed among the military services. DMA became operational on July 1, 1972, pursuant to General Order 3, DMA. On Oct. 1, 1996, DMA was folded into the National Imagery and Mapping Agency – which became NGA. DMA was first headquartered at the United States Naval Observatory in Washington, D. C at Falls Church, Virginia, its civilian workforce was concentrated at production sites in Bethesda, Northern Virginia, St. Louis, Missouri. DMA was formed from the Mapping and Geodesy Division, Defense Intelligence Agency, from various mapping-related organizations of the military services. DMA Hydrographic Center DMAHC was formed in
World War II
World War II known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries; the major participants threw their entire economic and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China, it included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, the only use of nuclear weapons in war. Japan, which aimed to dominate Asia and the Pacific, was at war with China by 1937, though neither side had declared war on the other. World War II is said to have begun on 1 September 1939, with the invasion of Poland by Germany and subsequent declarations of war on Germany by France and the United Kingdom.
From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Finland and the Baltic states. Following the onset of campaigns in North Africa and East Africa, the fall of France in mid 1940, the war continued between the European Axis powers and the British Empire. War in the Balkans, the aerial Battle of Britain, the Blitz, the long Battle of the Atlantic followed. On 22 June 1941, the European Axis powers launched an invasion of the Soviet Union, opening the largest land theatre of war in history; this Eastern Front trapped most crucially the German Wehrmacht, into a war of attrition. In December 1941, Japan launched a surprise attack on the United States as well as European colonies in the Pacific. Following an immediate U. S. declaration of war against Japan, supported by one from Great Britain, the European Axis powers declared war on the U.
S. in solidarity with their Japanese ally. Rapid Japanese conquests over much of the Western Pacific ensued, perceived by many in Asia as liberation from Western dominance and resulting in the support of several armies from defeated territories; the Axis advance in the Pacific halted in 1942. Key setbacks in 1943, which included a series of German defeats on the Eastern Front, the Allied invasions of Sicily and Italy, Allied victories in the Pacific, cost the Axis its initiative and forced it into strategic retreat on all fronts. In 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained its territorial losses and turned toward Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in Central China, South China and Burma, while the Allies crippled the Japanese Navy and captured key Western Pacific islands; the war in Europe concluded with an invasion of Germany by the Western Allies and the Soviet Union, culminating in the capture of Berlin by Soviet troops, the suicide of Adolf Hitler and the German unconditional surrender on 8 May 1945.
Following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender under its terms, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August respectively. With an invasion of the Japanese archipelago imminent, the possibility of additional atomic bombings, the Soviet entry into the war against Japan and its invasion of Manchuria, Japan announced its intention to surrender on 15 August 1945, cementing total victory in Asia for the Allies. Tribunals were set up by fiat by the Allies and war crimes trials were conducted in the wake of the war both against the Germans and the Japanese. World War II changed the political social structure of the globe; the United Nations was established to foster international co-operation and prevent future conflicts. The Soviet Union and United States emerged as rival superpowers, setting the stage for the nearly half-century long Cold War. In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia.
Most countries whose industries had been damaged moved towards economic expansion. Political integration in Europe, emerged as an effort to end pre-war enmities and create a common identity; the start of the war in Europe is held to be 1 September 1939, beginning with the German invasion of Poland. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred and the two wars merged in 1941; this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935; the British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the fo
A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses and to serve as a navigational aid for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs and safe entries to harbors. Once used, the number of operational lighthouses has declined due to the expense of maintenance and use of electronic navigational systems. Before the development of defined ports, mariners were guided by fires built on hilltops. Since raising the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and promontories, unlike many modern lighthouses; the most famous lighthouse structure from antiquity was the Pharos of Alexandria, which collapsed following a series of earthquakes between 956 and 1323. The intact Tower of Hercules at A Coruña, Spain gives insight into ancient lighthouse construction.
Coins from Alexandria and Laodicea in Syria exist. The modern era of lighthouses began at the turn of the 18th century, as lighthouse construction boomed in lockstep with burgeoning levels of transatlantic commerce. Advances in structural engineering and new and efficient lighting equipment allowed for the creation of larger and more powerful lighthouses, including ones exposed to the sea; the function of lighthouses shifted toward the provision of a visible warning against shipping hazards, such as rocks or reefs. The Eddystone Rocks were a major shipwreck hazard for mariners sailing through the English Channel; the first lighthouse built there was an octagonal wooden structure, anchored by 12 iron stanchions secured in the rock, was built by Henry Winstanley from 1696 to 1698. His lighthouse was the first tower in the world to have been exposed to the open sea; the civil engineer, John Smeaton, rebuilt the lighthouse from 1756–59. He modelled the shape of his lighthouse on that of an oak tree.
He rediscovered and used "hydraulic lime," a form of concrete that will set under water used by the Romans, developed a technique of securing the granite blocks together using dovetail joints and marble dowels. The dovetailing feature served to improve the structural stability, although Smeaton had to taper the thickness of the tower towards the top, for which he curved the tower inwards on a gentle gradient; this profile had the added advantage of allowing some of the energy of the waves to dissipate on impact with the walls. His lighthouse influenced all subsequent engineers. One such influence was Robert Stevenson, himself a seminal figure in the development of lighthouse design and construction, his greatest achievement was the construction of the Bell Rock Lighthouse in 1810, one of the most impressive feats of engineering of the age. This structure was based upon Smeaton's design, but with several improved features, such as the incorporation of rotating lights, alternating between red and white.
Stevenson worked for the Northern Lighthouse Board for nearly fifty years during which time he designed and oversaw the construction and improvement of numerous lighthouses. He innovated in the choice of light sources, reflector design, the use of Fresnel lenses, in rotation and shuttering systems providing lighthouses with individual signatures allowing them to be identified by seafarers, he invented the movable jib and the balance crane as a necessary part for lighthouse construction. Alexander Mitchell designed the first screw-pile lighthouse – his lighthouse was built on piles that were screwed into the sandy or muddy seabed. Construction of his design began in 1838 at the mouth of the Thames and was known as the Maplin Sands lighthouse, first lit in 1841. Although its construction began the Wyre Light in Fleetwood, was the first to be lit; the source of illumination had been wood pyres or burning coal. The Argand lamp, invented in 1782 by the Swiss scientist, Aimé Argand, revolutionized lighthouse illumination with its steady smokeless flame.
Early models used ground glass, sometimes tinted around the wick. Models used a mantle of thorium dioxide suspended over the flame, creating a bright, steady light; the Argand lamp used whale oil, olive oil or other vegetable oil as fuel, supplied by a gravity feed from a reservoir mounted above the burner. The lamp was first produced by Matthew Boulton, in partnership with Argand, in 1784 and became the standard for lighthouses for over a century. South Foreland Lighthouse was the first tower to use an electric light in 1875; the lighthouse's carbon arc lamps were powered by a steam-driven magneto. John Richardson Wigham was the first to develop a system for gas illumination of lighthouses, his improved gas'crocus' burner at the Baily Lighthouse near Dublin was 13 times more powerful than the most brilliant light known. The vaporized oil burner was invented in 1901 by Arthur Kitson, improved by David Hood at Trinity House; the fuel was vaporized at high pressure and burned to heat the mantle, giving an output of over six times the luminosity of traditional oil lights.
The use of gas as illuminant became available with the invention of the Dalén light by Swedish engineer, Gustaf Dalén. He used Agamassan, a substrate, to absorb the gas allowing safe storage and hence
Exposition Universelle (1867)
The International Exposition of 1867, was the second world's fair to be held in Paris, from 1 April to 3 November 1867. Forty-two nations were represented at the fair. Following a decree of Emperor Napoleon III, the exposition was prepared as early as 1864, in the midst of the renovation of Paris, marking the culmination of the Second French Empire. Visitors included Tsar Alexander II of Russia, a brother of the emperor of Japan, King William and Otto von Bismarck of Prussia, Prince Metternich and Franz Josef of Austria, Ottoman Sultan Abdülaziz, the Khedive of Egypt Isma'il. In 1864, Napoleon III decreed that an international exposition should be held in Paris in 1867. A commission was appointed with Prince Jerome Napoleon as president, under whose direction the preliminary work began; the site chosen for the Exposition Universelle of 1867 was the Champ de Mars, the great military parade ground of Paris, which covered an area of 119 acres and to, added the island of Billancourt, of 52 acres.
The principal building was rectangular in shape with rounded ends, having a length of 1608 feet and a width of 1247 feet, in the center was a pavilion surmounted by a dome and surrounded by a garden, 545 feet long and 184 feet wide, with a gallery built around it. In addition to the main building, there were nearly 100 smaller buildings on the grounds. Victor Hugo, Alexandre Dumas, Ernest Renan, Theophile Gautier all wrote publications to promote the event. There were 50,226 exhibitors, of whom 15,055 were from France and her colonies, 6176 from Great Britain and Ireland, 703 from the United States and a small contingent from Canada; the funds for the construction and maintenance of the exposition consisted of grants of $1,165,020 from the French government, a like amount from the city of Paris, about $2,000,000 from public subscription, making a total of $5,883,400. In the "gallery of Labour History" Jacques Boucher de Perthes, exposes one of the first prehistoric tools whose authenticity has been recognized with the accuracy of these theories.
The exhibition included two prototypes of the much acclaimed and prize-winning hydrochronometer invented in 1867 by Gian Battista Embriaco, O. P. professor at the College of St. Thomas in Rome. Among the horological exhibits, stood out a monumental model, an elaborate conical pendulum clock crafted by two of France's most important artisans of the second half of the 19th century—renowned clockmaker E. Farcot and sculptor Albert-Ernest Carrier-Be Belleuse. Farcot exhibited several units, one of them it is in the Roosevelt Hotel in New Orleans, its base, which features the clock's face and inner mechanical movements, is carved from solid onyx marble. Atop the base, a bronze sculpture depicting a robed female figure holds a scepter. Rotating soundlessly from the female subject's hand, the scepter provides consistent motion that adds to the clock's sense of grandeur and mystery. From its base to the top of the bronze figure stands at nearly 10 feet tall. Farcot, the most well-known of the French conical clock-makers, established himself in 1860 and mastered his craft over a period of 30 years, helping to popularize the unique pendulum escapement, the mechanism which controls the motion of the inner wheels.
Carrier de Belleuse was one of the most important and renowned sculptors of the 19th century, as well as the teacher of Auguste Rodin. In 1857, his bronze sculptures grabbed the attention of Napoleon III, he was commissioned for several important national works, including his most famous piece, which still flanks the staircase of the Paris Opera House. One of the Egyptian exhibits was designed by Auguste Mariette, featured ancient Egyptian monuments; the Suez Canal Company had an exhibit within the Egyptian exhibits, which it used to sell bonds for funding. The German manufacturer Krupp displayed a 50-ton cannon made of steel. Americans displayed their latest telegraph technology and both Cyrus Field and Samuel Morse provided speeches; the exposition was formally opened on 1 April and closed on 31 October 1867, was visited by 9,238,967 persons, including exhibitors and employees. This exposition was the greatest up to its time of all international expositions, both with respect to its extent and to the scope of its plan.
For the first time Japan presented art pieces to the world in a national pavilion pieces from the Satsuma and Saga clans in Kyushu. Vincent van Gogh and other artists of the post-impressionism movement of the late 19th century were part of the European art craze inspired by the displays seen here, wrote of the Japanese woodcut prints "that one sees everywhere and figures." Not only was Van Gogh a collector of the new art brought to Europe from a newly opened Japan, but many other French artists from the late 19th century were influenced by the Japanese artistic world-view, to develop into Japonism. The Paris street near Champs de Mars, Rue de L'Exposition was named in hommage to this 1867 universal exhibition. Jules Verne visited the exhibition in 1867, his take on the newly publicized discovery of electricity inspiring him in his writing of 20,000 Leagues Under the Sea. A famous revival of the ballet Le Corsaire was staged by the Ballet Master Joseph Mazilier in honor of the exhibition at the Théâtre Impérial de l´Opéra on 21 October 1867.
The World Rowing Championships were held on the Seine River in July and was won by the underdog Canadian team from Saint John
The English Channel called the Channel, is the body of water that separates Southern England from northern France and links the southern part of the North Sea to the Atlantic Ocean. It is the busiest shipping area in the world, it is about 560 km long and varies in width from 240 km at its widest to 33.3 km in the Strait of Dover. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2; until the 18th century, the English Channel had no fixed name either in French. It was never defined as a political border, the names were more or less descriptive, it was not considered as the property of a nation. Before the development of the modern nations, British scholars often referred to it as "Gaulish" and French scholars as "British" or "English"; the name "English Channel" has been used since the early 18th century originating from the designation Engelse Kanaal in Dutch sea maps from the 16th century onwards. In modern Dutch, however, it is known as Het Kanaal.
It has been known as the "British Channel" or the "British Sea". It was called Oceanus Britannicus by the 2nd-century geographer Ptolemy; the same name is used on an Italian map of about 1450, which gives the alternative name of canalites Anglie—possibly the first recorded use of the "Channel" designation. The Anglo-Saxon texts call it Sūð-sǣ as opposed to Norð-sǣ; the common word channel was first recorded in Middle English in the 13th century and was borrowed from Old French chanel, variant form of chenel "canal". The French name la Manche has been in use since at least the 17th century; the name is said to refer to the Channel's sleeve shape. Folk etymology has derived it from a Celtic word meaning channel, the source of the name for the Minch in Scotland, but this name was never mentioned before the 17th century, French and British sources of that time are clear about its etymology; the name in Breton means "Breton Sea", its Cornish name means "British Sea". The International Hydrographic Organization defines the limits of the English Channel as follows: The IHO defines the southwestern limit of the North Sea as "a line joining the Walde Lighthouse and Leathercoat Point".
The Walde Lighthouse is 6 km east of Calais, Leathercoat Point is at the north end of St Margaret's Bay, Kent. The Strait of Dover, at the Channel's eastern end, is its narrowest point, while its widest point lies between Lyme Bay and the Gulf of Saint Malo, near its midpoint, it is shallow, with an average depth of about 120 m at its widest part, reducing to a depth of about 45 m between Dover and Calais. Eastwards from there the adjoining North Sea reduces to about 26 m in the Broad Fourteens where it lies over the watershed of the former land bridge between East Anglia and the Low Countries, it reaches a maximum depth of 180 m in the submerged valley of Hurd's Deep, 48 km west-northwest of Guernsey. The eastern region along the French coast between Cherbourg and the mouth of the Seine river at Le Havre is referred to as the Bay of the Seine. There are several major islands in the Channel, the most notable being the Isle of Wight off the English coast, the Channel Islands, British Crown dependencies off the coast of France.
The coastline on the French shore, is indented. The Cotentin Peninsula in France juts out into the Channel, whilst on the English side there is a small parallel strait known as the Solent between the Isle of Wight and the mainland; the Celtic Sea is to the west of the Channel. The Channel acts as a funnel that amplifies the tidal range from less than a metre as observed at sea to more than 6 metres as observed in the Channel Islands, the west coast of the Cotentin Peninsula and the north coast of Brittany; the time difference of about six hours between high water at the eastern and western limits of the Channel is indicative of the tidal range being amplified further by resonance. In the UK Shipping Forecast the Channel is divided into the following areas, from the east: Dover Wight Portland Plymouth The Channel is of geologically recent origin, having been dry land for most of the Pleistocene period. Before the Devensian glaciation and Ireland were part of continental Europe, linked by an unbroken Weald-Artois Anticline, a ridge that acted as a natural dam holding back a large freshwater pro-glacial lake in the Doggerland region, now submerged under the North Sea.
During this period the North Sea and all of the British Isles were covered by ice. The lake was fed by meltwater from the Baltic and from the Caledonian and Scandinavian ice sheets that joined to the north, blocking its exit; the sea level was about 120 m lower. Between 450,000 and 180,000 years ago, at least two catastrophic glacial lake outburst floods breached the Weald–Artois anticline; the first flood would have lasted for several months, releasing as much as one million cubic metres of water per second. The flood started with large but localized waterfalls over the ridge, which excav
Côtes-d'Armor known as Côtes-du-Nord, is a department in the north of Brittany, in northwestern France. Côtes-du-Nord was one of the original 83 departments created on 4 March 1790 following the French Revolution, it was made up from the near entirety of the ancient Pays de Saint-Brieuc, most of historical Trégor, the eastern half of Cornouaille, the north-western part of the former diocese of Saint-Malo. In 1990 the name was changed to Côtes-d'Armor: the French word côtes means "coasts" and ar mor is "the sea" in Breton; the name recalls that of the Roman province of Armorica. Côtes-d'Armor is part of the current administrative region of Brittany and is bounded by the departments of Ille-et-Vilaine to the east, Morbihan to the south, Finistère to the west, by the English Channel to the north; the inhabitants of the department are known in French as Costarmoricains. Côtes-d'Armor's long tradition of anti-clericalism in the interior around Guingamp, has led to the department's being seen as an area of left-wing exceptionalism in an otherwise clerical and right-wing Brittany.
The current president of the departmental council, Alain Cadec, is a member of the centre-right party, Les Républicains. The western part of the département is part of the traditionally Breton-speaking "Lower Brittany"; the boundary runs from Plouha to Mûr-de-Bretagne. The Breton language has become an intense issue in many parts of Brittany, many Breton-speakers advocate for bilingual schools. Gallo is spoken in the east and is offered as a language in the schools and on the baccalaureat exams. Anne Beaumanoir, one of the Righteous Among the Nations, was born in Guildo. English-born poet Robert William Service, known as the "Bard of the Yukon", is buried in Lancieux.
