BYMS-class minesweeper
–
The BYMS class was a class of wooden motor minesweepers, part of the US Navy YMS Yard class minesweepers. 150 ships destined for UK were launched from 1941 to 1943, the initial 80 ships were ordered by the U. S. Navy specifically for transfer to the United Kingdom under the Lend-Lease Programme. On transfer to Britain, BYMS-1 to BYMS-80 were assigned the British pennant numbers BYMS-2001 to BYMS-2080, names were not assigned to the class members. A further 53 BYMS bore hull numbers from 137 to 284 and these were originally built for the U. S. Navy as part of the YMS class and transferred to Britain on, or shortly after, completion. On the Navy List they were designated BYMS, with their original U. S. Navy numbers, the remaining 17 BYMS vessels were delivered in a final batch. Jacques Cousteaus well-known ship Calypso was originally built by the Ballard Marine Railway Company of Seattle, Washington and she was a BYMS Mark 1 Class Motor Minesweeper, laid down on 12 August 1941 with the yard designation BYMS-26 and launched on 21 March 1942.

Seattle
–
Seattle is a seaport city on the west coast of the United States and the seat of King County, Washington. With an estimated 684,451 residents as of 2015, Seattle is the largest city in both the state of Washington and the Pacific Northwest region of North America. In July 2013, it was the major city in the United States. The city is situated on an isthmus between Puget Sound and Lake Washington, about 100 miles south of the Canada–United States border, a major gateway for trade with Asia, Seattle is the fourth-largest port in North America in terms of container handling as of 2015. The Seattle area was inhabited by Native Americans for at least 4,000 years before the first permanent European settlers. Arthur A. Denny and his group of travelers, subsequently known as the Denny Party, arrived from Illinois via Portland, the settlement was moved to the eastern shore of Elliott Bay and named Seattle in 1852, after Chief Siahl of the local Duwamish and Suquamish tribes. Logging was Seattles first major industry, but by the late-19th century, growth after World War II was partially due to the local Boeing company, which established Seattle as a center for aircraft manufacturing. The Seattle area developed as a technology center beginning in the 1980s, in 1994, Internet retailer Amazon was founded in Seattle. The stream of new software, biotechnology, and Internet companies led to an economic revival, Seattle has a noteworthy musical history. From 1918 to 1951, nearly two dozen jazz nightclubs existed along Jackson Street, from the current Chinatown/International District, to the Central District, the jazz scene developed the early careers of Ray Charles, Quincy Jones, Ernestine Anderson, and others. Seattle is also the birthplace of rock musician Jimi Hendrix and the alternative rock subgenre grunge, archaeological excavations suggest that Native Americans have inhabited the Seattle area for at least 4,000 years. By the time the first European settlers arrived, the people occupied at least seventeen villages in the areas around Elliott Bay, the first European to visit the Seattle area was George Vancouver, in May 1792 during his 1791–95 expedition to chart the Pacific Northwest. In 1851, a party led by Luther Collins made a location on land at the mouth of the Duwamish River. Thirteen days later, members of the Collins Party on the way to their claim passed three scouts of the Denny Party, members of the Denny Party claimed land on Alki Point on September 28,1851. The rest of the Denny Party set sail from Portland, Oregon, after a difficult winter, most of the Denny Party relocated across Elliott Bay and claimed land a second time at the site of present-day Pioneer Square, naming this new settlement Duwamps. For the next few years, New York Alki and Duwamps competed for dominance, david Swinson Doc Maynard, one of the founders of Duwamps, was the primary advocate to name the settlement after Chief Sealth of the Duwamish and Suquamish tribes. The name Seattle appears on official Washington Territory papers dated May 23,1853, in 1855, nominal land settlements were established. On January 14,1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of managing the city

Washington (state)
–
It was admitted to the Union as the 42nd state in 1889. Washington is sometimes referred to as Washington State or the State of Washington to distinguish it from Washington, Washington is the 18th largest state with an area of 71,362 square miles, and the 13th most populous state with over 7 million people. Washington is the second most populous state on the West Coast and in the Western United States, Mount Rainier, an active stratovolcano, is the states highest elevation at almost 14,411 feet and is the most topographically prominent mountain in the contiguous United States. Washington is a leading lumber producer and its rugged surface is rich in stands of Douglas fir, hemlock, ponderosa pine, white pine, spruce, larch, and cedar. Manufacturing industries in Washington include aircraft and missiles, shipbuilding and other equipment, lumber, food processing, metals and metal products, chemicals. Washington has over 1,000 dams, including the Grand Coulee Dam, built for a variety of purposes including irrigation, power, flood control, the Washington Territory was named after George Washington, the first President of the United States. The area was part of a region called the Columbia District after the Columbia River. The area was renamed Washington in order to avoid confusion with the District of Columbia, Washington is the only U. S. state named after a president. To distinguish it from the U. S. capital, which is named for George Washington, Washington is sometimes referred to as Washington State, or, in more formal contexts. Washingtonians and other residents of the Pacific Northwest refer to the state simply as Washington, calling the nations capital Washington, D. C. or, often, Washington is the northwestern-most state of the contiguous United States. Washington is bordered by Oregon to the south, with the Columbia River forming the western part, to the west of Washington lies the Pacific Ocean. The high mountains of the Cascade Range run north-south, bisecting the state, from the Cascade Mountains westward, Western Washington has a mostly marine west coast climate, with mild temperatures and wet winters, autumns and springs, and relatively dry summers. The Cascade Range contains several volcanoes, which reach altitudes significantly higher than the rest of the mountains, from the north to the south, these major volcanoes are Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams. Mount Rainier, the tallest mountain in the state, is 50 miles south of the city of Seattle and it is also covered with more glacial ice than any other peak in the contiguous 48 states. Western Washington also is home of the Olympic Mountains, far west on the Olympic Peninsula and these deep forests, such as the Hoh Rainforest, are among the only temperate rainforests in the continental United States. Eastern Washington – the part of the state east of the Cascades – has a dry climate. It includes large areas of steppe and a few truly arid deserts lying in the rain shadow of the Cascades. Farther east, the climate becomes less arid, with annual rainfall increasing as one goes east to 21.2 inches in Pullman, the Okanogan Highlands and the rugged Kettle River Range and Selkirk Mountains cover much of the northeastern quadrant of the state

Research vessel
–
A research vessel is a ship or boat designed, modified, and/or equipped to carry out research at sea. Research vessels carry out a number of roles, some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the nature of the work, research vessels are often constructed around an icebreaker hull. The research ship had origins in the voyages of exploration. By the time of James Cooks Endeavour, the essentials of what today we would call a ship are clearly apparent. In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe, the Endeavour was a sturdy boat, well designed and equipped for the ordeals she would face, and fitted out with facilities for her research personnel, Joseph Banks. And, as is common with contemporary research vessels, Endeavour carried out more than one kind of research, some other notable early research vessels were HMS Beagle, RV Calypso, HMS Challenger, USFC Albatross, and the Endurance and Terra Nova. The names of early research vessels have been used to later research vessels. A hydrographic survey ship is a designed to conduct hydrographic research. Nautical charts are produced from this information to ensure safe navigation by military, hydrographic survey vessels also conduct seismic surveys of the seabed and the underlying geology. Apart from producing the charts, this information is useful for detecting geological features which are likely to bear oil or gas, in practice, hydrographic survey vessels are often equipped to perform multiple roles. Some function also as oceanographic research ships, naval hydrographic survey vessels often do naval research, for example, on submarine detection. An example of a survey vessel is CCGS Frederick G. Creed. For an example of the employment of a survey ship see HMS Hydra and these vessels often also carry scientific divers and unmanned underwater vehicles. Since the requirements of both oceanographic and hydrographic research are very different from those of fisheries research, these boats often fulfill dual roles, examples of an oceanographic research vessel include the NOAAS Ronald H. Brown and the Chilean Navy Cabo de Hornos. An example of a research vessel is FRV Scotia. Naval research vessels investigate naval concerns, such as submarine and mine detection, sonar, an example of a naval research vessel is the Planet of the German Navy. Polar research vessels are constructed around a hull, allowing them to operate in polar waters

Jacques Cousteau
–
Jacques-Yves Cousteau AC was a French naval officer, explorer, conservationist, filmmaker, innovator, scientist, photographer, author and researcher who studied the sea and all forms of life in water. He co-developed the Aqua-lung, pioneered marine conservation and was a member of the Académie française, Cousteau also directed films, most notably the documentary adaptation of the book, The Silent World, which won a Palme dor at the 1956 Cannes Film Festival. He remained the only person to win a Palme dOr for a documentary film, Cousteau was born on 11 June 1910, in Saint-André-de-Cubzac, Gironde, France to Daniel and Élisabeth Cousteau. Cousteau completed his studies at the Collège Stanislas in Paris. In 1930, he entered the École Navale and graduated as a gunnery officer, after an automobile accident cut short his career in naval aviation, Cousteau indulged his interest in the sea. The accident caused him to both his arms and could have even killed him. This caused Cousteau to have to change his plans in becoming a naval pilot, Cousteau also belonged to the information service of the French Navy, and was sent on missions to Shanghai and Japan and in the USSR. On 12 July 1937 he married Simone Melchior, with whom he had two sons, Jean-Michel and Philippe and his sons took part in the adventures of the Calypso. In 1991, one year after his wife Simones death from cancer and they already had a daughter Diane Cousteau and a son Pierre-Yves Cousteau, born during Cousteaus marriage to his first wife. The years of World War II were decisive for the history of diving, after the armistice of 1940, the family of Simone and Jacques-Yves Cousteau took refuge in Megève, where he became a friend of the Ichac family who also lived there. Jacques-Yves Cousteau and Marcel Ichac shared the desire to reveal to the general public unknown and inaccessible places — for Cousteau the underwater world. In 1943, they made the film Épaves, in which used two of the very first Aqua-Lung prototypes. These prototypes were made in Boulogne-Billancourt by the Air Liquide company, following instructions from Cousteau, at that time, he kept his distance from his brother Pierre-Antoine Cousteau, a pen anti-semite who wrote the collaborationist newspaper Je suis partout and who received the death sentence in 1946. However, this was commuted to a life sentence. During the 1940s, Cousteau is credited with improving the design which gave birth to the open-circuit scuba technology used today. In 1943 Cousteau tried out the first prototype aqua-lung which finally made extended underwater exploration possible, a little later it became the GERS, then the COMISMER, and finally more recently the CEPHISMER. In 1947, Chief Petty Officer Maurice Fargues became the first diver to die using an aqualung while attempting a new record with the GERS near Toulon. The small team also undertook the exploration of the Roman wreck of Mahdia and it was the first underwater archaeology operation using autonomous diving, opening the way for scientific underwater archaeology

Electro-Motive Diesel
–
Electro-Motive Diesel is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail Services Corporation, in 1930, General Motors purchased Electro-Motive Company and the Winton Engine Co. combining the two to form its Electro-Motive Division in 1941. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, in 2010, Progress Rail Services completed the purchase of Electro-Motive Diesel from Greenbriar, Berkshire, and others. EMDs headquarters, engineering facilities and parts manufacturing operations are based in McCook, Illinois, while its final assembly line is located in Muncie. EMD also operates a traction motor maintenance, rebuild and overhaul facility in San Luis Potosí, as of 2008, EMD employed approximately 3,260 people, and in 2010 it held approximately 30 percent of the market for diesel-electric locomotives in North America. Harold L. Hamilton and Paul Turner founded the Electro-Motive Engineering Corporation in Cleveland, Ohio, in 1922, the company developed and marketed self-propelled railcars using General Electrics newly developed internal combustion-electric propulsion and control systems. Hamilton started his career as a fireman, then locomotive engineer, on the Southern Pacific Railroad. Financing himself, he quit his sales position and set up shop in a hotel with his partner. In 1923 EMC sold two gasoline-powered rail motor cars, one to the Chicago Great Western and the other to the Northern Pacific, EMC subcontracted the body construction to St. Louis Car Company, electrical components to General Electric, and the prime mover to Winton Engine Company. The motorcars were delivered in 1924 and worked well, fortunate for the fledgling company, in 1925, EMC entered full-scale production, selling 27 railcars. In 1930 General Motors was seeking to improve their Diesel technology and they purchased the Winton Engine Company who, in addition to their Diesel products, sold non-Diesel engines for EMC-developed rail motorcars. The combined resources of GM and their new Winton subsidiary were focused on developing Diesel engines with improved power-to-weight ratios, GM saw EMCs role in marketing and applications development as fitting their objectives and purchased the company shortly after the Winton acquisition, renaming it Electro-Motive Corporation. In 1933 EMC designed the power setups for the Zephyr and M-10000 streamliners, the Zephyr used the first major product of the new GM-Winton venture, the 600 hp Winton 201A 2-stroke Diesel engine. Encouraged by the success of the new streamliners, EMC invested in a new locomotive factory. The new headquarters on 55th Street in McCook, Illinois, west of Chicago, in 1938 EMC started production of locomotives using GMs new 567 engine, which upgraded the horsepower to 2000 per locomotive unit and increased reliability. The 567, named for its displacement-per-cylinder of 567.45 in³, was a two-cycle Roots-blown, Uniflow-scavenged, Unit-injected engine with overhead camshafts and it was built as a V-6, V-8, V-12 and V-16. Charles F. Kettering and the General Motors Research Corporation were in charge of its development and their nearest competitor was the American Locomotive Company, who started production of less-developed Diesel locomotives to compete with the E-units in 1939. Baldwins response to the challenge of the E-units was to develop a steam locomotive design that pushed beyond the limits of practicality, passenger trains made little money for the railroads, but replacement of steam engines with reliable Diesel units could provide railroads with a crucial difference for profitability

Royal Navy
–
The Royal Navy is the United Kingdoms naval warfare force. Although warships were used by the English kings from the medieval period. The modern Royal Navy traces its origins to the early 16th century, from the middle decades of the 17th century and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century it was the worlds most powerful navy until surpassed by the United States Navy during the Second World War. The Royal Navy played a key part in establishing the British Empire as the world power during the 19th. Due to this historical prominence, it is common, even among non-Britons, following World War I, the Royal Navy was significantly reduced in size, although at the onset of the Second World War it was still the worlds largest. By the end of the war, however, the United States Navy had emerged as the worlds largest, during the Cold War, the Royal Navy transformed into a primarily anti-submarine force, hunting for Soviet submarines, mostly active in the GIUK gap. The Royal Navy is part of Her Majestys Naval Service, which includes the Royal Marines. The professional head of the Naval Service is the First Sea Lord, the Defence Council delegates management of the Naval Service to the Admiralty Board, chaired by the Secretary of State for Defence. The strength of the fleet of the Kingdom of England was an important element in the power in the 10th century. English naval power declined as a result of the Norman conquest. Medieval fleets, in England as elsewhere, were almost entirely composed of merchant ships enlisted into service in time of war. Englands naval organisation was haphazard and the mobilisation of fleets when war broke out was slow, early in the war French plans for an invasion of England failed when Edward III of England destroyed the French fleet in the Battle of Sluys in 1340. Major fighting was confined to French soil and Englands naval capabilities sufficed to transport armies and supplies safely to their continental destinations. Such raids halted finally only with the occupation of northern France by Henry V. Henry VII deserves a large share of credit in the establishment of a standing navy and he embarked on a program of building ships larger than heretofore. He also invested in dockyards, and commissioned the oldest surviving dry dock in 1495 at Portsmouth, a standing Navy Royal, with its own secretariat, dockyards and a permanent core of purpose-built warships, emerged during the reign of Henry VIII. Under Elizabeth I England became involved in a war with Spain, the new regimes introduction of Navigation Acts, providing that all merchant shipping to and from England or her colonies should be carried out by English ships, led to war with the Dutch Republic. In the early stages of this First Anglo-Dutch War, the superiority of the large, heavily armed English ships was offset by superior Dutch tactical organisation and the fighting was inconclusive

Minesweeper
–
A minesweeper is a small naval warship designed to engage in minesweeping. Using various mechanisms intended to counter the threat posed by naval mines, although naval warfare has a long history, the earliest known usage of the naval mine dates to the Ming dynasty. Dedicated minesweepers, however, only appear in the record several centuries later, to the Crimean War. In the Crimean War, minesweepers consisted of British rowboats trailing grapnels to snag the mines, despite the use of mines in the American Civil War, there are no records of effective minesweeping being used. Officials in the Union Army attempted to create the first minesweeper but were plagued by flawed designs, minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nations shipping, sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. A Trawler Section of the Royal Navy Reserve became the predecessor of the mine sweeping forces with specially designed ships and these reserve Trawler Section fishermen and their trawlers were activated, supplied with mine gear, rifles, uniforms and pay as the first minesweepers. The dedicated, purpose-built minesweeper first appeared during World War I with the Flower-class minesweeping sloop, by the end of the War, naval mine technology had grown beyond the ability of minesweepers to detect and remove. Minesweeping made significant advancements during World War II, combatant nations quickly adapted ships to the task of minesweeping, including Australias 35 civilian ships that became Auxiliary Minesweepers. Both Allied and Axis countries made heavy use of minesweepers throughout the war, historian Gordon Williamson wrote that Germanys minesweepers alone formed a massive proportion of its total strength, and are very much the unsung heroes of the Kriegsmarine. Naval mines remained a threat even after the war ended, after the Second World War, allied countries worked on new classes of minesweepers ranging from 120-ton designs for clearing estuaries to 735-ton oceangoing vessels. The United States Navy even used specialized Mechanized Landing Craft to sweep shallow harbors in, as of June 2012, the U. S. Navy had four minesweepers deployed to the Persian Gulf to address regional instabilities. Minesweepers are equipped with mechanical or electrical devices, known as sweeps, mechanical sweeps are devices designed to cut the anchoring cables of moored mines, and preferably attach a tag to help the subsequent localization and neutralization. They are towed behind the minesweeper, and use a body to maintain the sweep at the desired depth. Influence sweeps are equipment, often towed, that emulate a particular ship signature, the most common such sweeps are magnetic and acoustic generators. There are two modes of operating an influence sweep, MSM and TSM, MSM sweeping is founded on intelligence on a given type of mine, and produces the output required for detonation of this mine. If such intelligence is unavailable, the TSM sweeping instead reproduces the influence of the ship that is about to transit through the area. TSM sweeping thus clears mines directed at this ship without knowledge of the mines, however, mines directed at other ships might remain

Oceanography
–
Oceanography, also known as oceanology, is the study of the physical and the biological aspects of the ocean. Paleoceanography studies the history of the oceans in the geologic past, humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations on tides were recorded by Aristotle and Strabo, early exploration of the oceans was primarily for cartography and mainly limited to its surfaces and of the animals that fishermen brought up in nets, though depth soundings by lead line were taken. Although Juan Ponce de León in 1513 first identified the Gulf Stream, Franklin measured water temperatures during several Atlantic crossings and correctly explained the Gulf Streams cause. Franklin and Timothy Folger printed the first map of the Gulf Stream in 1769-1770, information on the currents of the Pacific Ocean was gathered by explorers of the late 18th century, including James Cook and Louis Antoine de Bougainville. James Rennell wrote the first scientific textbooks on oceanography, detailing the current flows of the Atlantic, during a voyage around the Cape of Good Hope in 1777, he mapped the banks and currents at the Lagullas. He was also the first to understand the nature of the intermittent current near the Isles of Scilly, Robert FitzRoy published a four-volume report of the Beagles three voyages. In 1841–1842 Edward Forbes undertook dredging in the Aegean Sea that founded marine ecology, the first superintendent of the United States Naval Observatory, Matthew Fontaine Maury devoted his time to the study of marine meteorology, navigation, and charting prevailing winds and currents. His 1855 textbook Physical Geography of the Sea was one of the first comprehensive oceanography studies, many nations sent oceanographic observations to Maury at the Naval Observatory, where he and his colleagues evaluated the information and distributed the results worldwide. Despite all this, human knowledge of the oceans remained confined to the topmost few fathoms of the water, almost nothing was known of the ocean depths. The Royal Navys efforts to all of the worlds coastlines in the mid-19th century reinforced the vague idea that most of the ocean was very deep. As exploration ignited both popular and scientific interest in the regions and Africa, so too did the mysteries of the unexplored oceans. The seminal event in the founding of the science of oceanography was the 1872-76 Challenger expedition. As the first true oceanographic cruise, this laid the groundwork for an entire academic. In response to a recommendation from the Royal Society, The British Government announced in 1871 an expedition to explore worlds oceans, charles Wyville Thompson and Sir John Murray launched the Challenger expedition. The Challenger, leased from the Royal Navy, was modified for scientific work, under the scientific supervision of Thomson, Challenger travelled nearly 70,000 nautical miles surveying and exploring. On her journey circumnavigating the globe,492 deep sea soundings,133 bottom dredges,151 open water trawls and 263 serial water temperature observations were taken, around 4,700 new species of marine life were discovered. The result was the Report Of The Scientific Results of the Exploring Voyage of H. M. S, Murray, who supervised the publication, described the report as the greatest advance in the knowledge of our planet since the celebrated discoveries of the fifteenth and sixteenth centuries
