Sappers Divers Group
The Divers Group (AGRUMERG, pt, Agrupamento de Mergulhadores) is the Portuguese Navy's diving unit. It was created in 2004 through the grouping of the several already existing diving subunits, to exercise administrative, logistical and operational control and management, over all diver units and personnel. It groups under a single command, all previously existing Sappers Divers Units (EOD/Combat Divers, Salvage/SAR, MCM/MW) and Services (Training and Logistics). Organization The Divers Group is a command, within the Portuguese Navy Subsurface Squadron, and is commanded by a senior naval officer. It includes: * Commander *Operations Cell * Diving Service (''Serviço de Mergulho'') - Logistics * Divers School (''Escola de Mergulhadores'') - Training * Sappers Divers Detachment No. 1 (''Destacamento de Mergulhadores Sapadores N.º1 - DMS1'') - EOD / Combat Divers * Sappers Divers Detachment No. 2 (''Destacamento de Mergulhadores Sapadores N.º2 - DMS2'') - Salvage / SAR * Sappers ...

Explosive Ordnance Disposal
Bomb disposal is an explosives engineering profession using the process by which hazardous explosive devices are rendered safe. ''Bomb disposal'' is an all-encompassing term to describe the separate, but interrelated functions in the military fields of explosive ordnance disposal (EOD) and improvised explosive device disposal (IEDD), and the public safety roles of public safety bomb disposal (PSBD) and the bomb squad. History The first professional civilian bomb squad was established by Sir Vivian Dering Majendie. As a Major in the Royal Artillery, Majendie investigated an explosion on 2 October 1874 in the Regent's Canal, when the barge 'Tilbury', carrying six barrels of petroleum and five tons of gunpowder, blew up, killing the crew and destroying Macclesfield Bridge and cages at nearby London Zoo. In 1875, he framed The Explosives Act, the first modern legislation for explosives control. He also pioneered many bomb disposal techniques, including remote methods for the ha ...

Shore
A shore or a shoreline is the fringe of land at the edge of a large body of water, such as an ocean, sea, or lake. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. In contrast to a coast, a shore can border any body of water, while the coast must border an ocean or a sea. Therefore, in that sense, a coast is a type of shore. However, the word "coast" often refers to an area far wider than the shore, often stretching miles into the interior. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore which is created. Rivieras ''Riviera'' is an Italian word for "shoreline", ultimately derived from Latin ''ripa'' ("riverbank"). It came to be applied as a proper n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combat Diving
A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word ''frogman'' first arose in the stage name ''The Fearless Frogman'' of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit. The term ''frogman'' is occasionally used to refer to a civilian scuba diver. Some sport diving clubs include the word ''Frogmen'' in their names. The preferred term by scuba users is ''diver'', but the ''frogman'' epithet persists in informal usage by non-divers, especially in the media and often referring to professional scuba divers, such as in a police diving role. In the U.S. military and intelligence community, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Units And Formations Established In 2004
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''.

Deep Diving
Deep diving is underwater diving to a depth beyond the norm accepted by the associated community. In some cases this is a prescribed limit established by an authority, while in others it is associated with a level of certification or training, and it may vary depending on whether the diving is recreational, technical or commercial. Nitrogen narcosis becomes a hazard below and hypoxic breathing gas is required below to lessen the risk of oxygen toxicity. For some recreational diving agencies, "Deep diving", or "Deep diver" may be a certification awarded to divers that have been trained to dive to a specified depth range, generally deeper than . However, the Professional Association of Diving Instructors (PADI) defines anything from as a "deep dive" in the context of recreational diving (other diving organisations vary), and considers ''deep diving'' a form of technical diving. In technical diving, a depth below about where hypoxic breathing gas becomes necessary to avoid oxyge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hintze Ribeiro Disaster
At about 21:00 on the night of 4 March 2001, the Hintze Ribeiro disaster (also known as Entre-os-Rios disaster) occurred when the steel and concrete Hintze Ribeiro Bridge collapsed in Entre-os-Rios, Castelo de Paiva, northern Portugal, killing 59 people, including those in a bus from the Asadouro company and three cars that were crossing the Douro river. Fast waters and a storm at the time gave no chance for an immediate rescue, and the victims drowned. The strong river current carried bodies downstream more than to the Atlantic ocean. Bodies were found as far away as the north coast of Spain and one even in France. Hours after the accident, the Minister of Social Equipment Jorge Coelho resigned. The following week, dozens of bridges across Portugal were closed for immediate repair. The tragedy caused widespread shock across the nation, with all television networks broadcasting continuous news bulletins, and many solidarity campaigns being organized to help the victims' relat ...

Praça Do Comércio
The Praça do Comércio (; ) is a large, harbour-facing plaza in Portugal's capital, Lisbon, and is one of the largest in Portugal, with an area of 175 by 175 m (574 by 574 ft), that is, 30,600 m2 (329,000 ft2). Facing the Tagus () to the South, the plaza is still commonly known in Portuguese as Terreiro do Paço ( (), as it hosted the Paço da Ribeira () until the latter was destroyed by the great 1755 Lisbon earthquake (the subway station located there is still named after the old name of the plaza). After the earthquake, the plaza was completely remodeled as part of the rebuilding of the Pombaline Downtown (''Baixa''), ordered by Sebastião José de Carvalho e Melo, 1st Marquis of Pombal, who was (chief) Minister of Portugal from 1750 to 1777, during the reign of the Portuguese King José I. From the 19th century onwards, Praça do Comércio became the seat of some of the most important Portuguese state departments, including the Ministries of Finances, Internal Administra ...

Lisbon Metro
The Lisbon Metro ( pt, Metropolitano de Lisboa) is the rapid transit system in Lisbon, Portugal. Opened in December 1959, it was the first metro system in Portugal. , the system's four lines total of route and serve 56 stations. History Initial plans The idea of building a system of underground railways for the city of Lisbon first arose in 1888. It was first proposed by Henrique de Lima e Cunha, a military engineer who had published a proposal in the journal ''Obras Públicas e Minas'' ''(Public Works and Mines)'' for a network with several lines that could serve the Portuguese capital. Concrete plans took longer to evolve, though. Lanoel Aussenac d'Abel and Abel Coelho presented theirs in 1923, and José Manteca Roger and Juan Luque Argenti theirs one year later, in 1924. None of these plans were carried out. After World War II, in which Portugal remained neutral, the national economy took off and the financial possibilities arising from the Marshall Plan provided a stro ...

Seabed
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates mid-ocean ridges along the center line of major ocean basins, where the seabed is slightly shallower than the surrounding abyssal plain. From the abyssal plain, the seabed slopes upward toward the continents and becomes, in order from deep to shallow, the continental rise, slope, and shelf. The depth within the seabed itself, such as the depth down through a sediment core, is known as the “depth below seafloor.” The ecological environment of the seabed and the deepest waters are collectively known, as a habitat for creatures, as the “benthos.” Most of the seabed throughout the world's oceans is covered in layers of marine sediments. ...
