Argus Island
Argus Island was an acoustics, acoustic research tower and platform located on Plantagenet Bank, a guyot about 30 miles southwest of the island of Bermuda. The tower was originally part of the facilities supporting Project Artemis and Project Trident under auspices of the Naval Facility Bermuda, Tudor Hill Laboratory, a facility of the US Navy's Naval Undersea Warfare Center, Underwater Sound Laboratory.The Tudor Hill Laboratory and Argus Island were acoustic research and development facilities not a part of the Sound Surveillance System (SOSUS). The laboratory was adjacent to the Naval Facility (NAVFAC) Bermuda and was the only Atlantic R&D laboratory with access to an operational SOSUS facility. As a result, partly due to cover story of the NAVFAC as "oceanographic research" the two were often associated and confused as a single entity. Later the tower was used for additional acoustic experiments as well as oceanographic observations, wave height measurements, optical observations, ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Naval Research Laboratory
The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. Located in Washington, DC, it was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research. As of 2016, NRL was a United States Navy Working Capital Fund, Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year.

Jet Fuel
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by Gas turbine, gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Furthermore, the range of molecular mass between hydrocarbons (or different carbon numbers) is defined by the requirements for the product, such as the freezing point or smoke point. Keros ...

SEALAB I Is Lowered Near Argus Island Tower In 1964
SEALAB I, II, and III were experimental underwater habitats developed and deployed by the United States Navy during the 1960s to prove the viability of saturation diving and humans living in isolation for extended periods of time. The knowledge gained from the SEALAB expeditions helped advance the science of underwater diving, deep sea diving and rescue and contributed to the understanding of the psychological and physiological strains humans can endure. United States Navy Genesis Project Preliminary research work was undertaken by George F. Bond, who named the project after the Book of Genesis, which prophesised humans would gain dominion over the oceans. Bond began investigations in 1957 to develop theories about saturation diving. Bond's team exposed rats, goats, monkeys, and human beings to various gas mixtures at different pressures. By 1963 they had collected enough data to test the first SEALAB habitat. At the time, Jacques Cousteau and Edwin A. Link were pursuing privat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SOSUS
Sound Surveillance System (SOSUS) was the original name for a submarine detection system based on passive sonar developed by the United States Navy to track Soviet Navy, Soviet submarines. The system's true nature was classified with the name and acronym SOSUS classified as well. The unclassified name ''Project Caesar'' was used to cover the installation of the system and a cover story developed regarding the shore stations, identified only as a Naval Facility (NAVFAC), being for oceanographic research. The name changed to Integrated Undersea Surveillance System (IUSS) in 1985, as the fixed bottom arrays were supplemented by the mobile Surveillance Towed Array Sensor System (SURTASS) and other new systems. The commands and personnel were covered by the "oceanographic" term until 1991 when the mission was declassified. As a result, the commands, Oceanographic System Atlantic and Oceanographic System Pacific became Undersea Surveillance Atlantic and Undersea Surveillance Pacific, a ...

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Naval Facility Bermuda
Naval Facility Bermuda, or NAVFAC Bermuda, was the operational shore terminus for one of the Atlantic SOSUS, Sound Surveillance System (SOSUS) array systems installed during the first phase of system installation and in commission from 1955 until 1992. The true surveillance mission was classified and covered by "oceanographic research" until the mission was declassified in 1991. The system's acoustic data was collected after the facility was decommissioned until the system was routed to the central processing facility, the Naval Ocean Processing Facility (NOPF), Dam Neck, Virginia in 1994. The operational surveillance facility was often confused with the adjacent research facility, the Tudor Hill Laboratory, and its undersea sensors supporting research and development for Navy acoustic systems. That laboratory was the only such research and development facility with access to an operational surveillance facility. When that laboratory, then a detachment of the Naval Undersea Warfar ...
