Side-scan Sonar
Side-scan sonar (also sometimes called side scan sonar, sidescan sonar, side imaging sonar, side-imaging sonar and bottom classification sonar) is a category of sonar system that is used to efficiently create an image of large areas of the sea floor. Uses Side scan sonar is used to image large areas of the seafloor quickly. Applications include surveys for marine archaeology, shipwreck hunting, search and recovery (SAR), and environmental monitoring. In conjunction with seafloor samples, it is able to provide an understanding of the differences in material and texture type of the seabed. Side-scan sonar imagery is also a commonly used tool to detect debris items and other obstructions on the seafloor that may be hazardous to shipping or to seafloor installations by the oil and gas industry. In addition, the status of pipelines and cables on the seafloor can be investigated using side-scan sonar. Side-scan data are frequently acquired along with bathymetric soundings and s ...

Transducer
A transducer is a device that Energy transformation, converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. Transducers are often employed at the boundaries of automation, Measuring instrument, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). The process of converting one form of energy to another is known as transduction. Types * Mechanical transducers convert physical quantities into mechanical outputs or vice versa; * Electrical transducers convert physical quantities into electrical outputs or signals. Examples of these are: ** a thermocouple that changes temperature differences into a small voltage; ** a linear variable differential transformer (LVDT), used to measure displacement (position) changes by means of electrical signals. Sensors, actuators and transceivers Transducers can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Oceanography Centre
The National Oceanography Centre (NOC) is a marine science research and technology institute based across two sites, one in Southampton and one in Liverpool, England. It is the UK’s largest institute for integrated sea level science, coastal and deep ocean research and technology development. The Centre was established to promote co-operation with institutions across the UK marine science community, to better address key issues including sea level change, the ocean's role in climate change, computer simulation of the ocean's behaviour, and the long term monitoring and future of the Arctic Circle. Marine science national capability The NOC operates ships and equipment which contribute to the country's national marine capability. Such equipment provided by the NOC includes Royal Research Ships, and , deep submersibles, including the Autosub autonomous underwater vehicles (AUVs), advanced ocean sensors and other instruments including Boaty McBoatface.

Wreck Of The RMS Titanic
The wreck of British ocean liner RMS ''Titanic'' lies at a depth of about , about south-southeast off the coast of Newfoundland. It lies in two main pieces about apart. The bow is still recognisable with many preserved interiors, despite deterioration and damage sustained by hitting the sea floor; in contrast, the stern is heavily damaged. The debris field around the wreck contains hundreds of thousands of items spilled from the ship as she sank. The ''Titanic'' sank in 1912, following her collision with an iceberg during her maiden voyage. Numerous expeditions unsuccessfully tried using sonar to map the seabed in the hope of finding the wreckage. In 1985, the wreck was finally located by a joint French–American expedition led by Jean-Louis Michel of IFREMER and Robert Ballard of the Woods Hole Oceanographic Institution, originally on a mission to find two nuclear Cold War submarines. The wreck has been the focus of intense interest and has been visited by numerous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIND Technology, Inc
The mind is that which thinks, feels, perceives, imagines, remembers, and wills. It covers the totality of mental phenomena, including both conscious processes, through which an individual is aware of external and internal circumstances, and unconscious processes, which can influence an individual without intention or awareness. The mind plays a central role in most aspects of human life, but its exact nature is disputed. Some characterizations focus on internal aspects, saying that the mind transforms information and is not directly accessible to outside observers. Others stress its relation to outward conduct, understanding mental phenomena as dispositions to engage in observable behavior. The mind–body problem is the challenge of explaining the relation between matter and mind. Traditionally, mind and matter were often thought of as distinct substances that could exist independently from one another. The dominant philosophical position since the 20th century has be ...

George Bass (archeologist)
George Fletcher Bass (; December 9, 1932 – March 2, 2021) was an American archaeologist. An early practitioner of underwater archaeology, he co-directed the first expedition to entirely excavate an ancient shipwreck at Cape Gelidonya in 1960 and founded the Institute of Nautical Archaeology in 1972. Early life and education Bass was born on December 9, 1932, in Columbia, South Carolina to Robert Duncan Bass, an English Literature professor and scholar of the American Revolutionary War, and Virginia Wauchope, a writer. His uncle was the archaeologist Robert Wauchope. In 1940 Bass moved with his family to Annapolis, Maryland, where his father took up active service with the US Navy in World War II and taught English at the United States Naval Academy. He was interested in both astronomy and the sea as a youth and did odd jobs for Ben Carlin, an adventurer who was the first person to circumnavigate the world in an amphibious vehicle. After graduating high school he began study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mary Rose
The ''Mary Rose'' was a carrack in the English Tudor navy of Henry VIII of England, King Henry VIII. She was launched in 1511 and served for 34 years in several wars against France, Scotland, and Brittany. After being substantially rebuilt in 1536, she saw her last action on 1545. She led the attack on the galleys of a French invasion fleet, but sank off Spithead in the Solent, the strait north of the Isle of Wight. The wreck of the ''Mary Rose'' was located in 1971 and was raised on 11 October 1982 by the Mary Rose Trust in one of the most complex and expensive maritime salvage projects in history. The surviving section of the ship and thousands of recovered artefacts are of great value as a Tudor period time capsule. The excavation and raising of the ''Mary Rose'' was a milestone in the field of maritime archaeology, comparable in complexity and cost to the raising of the 17th-century Swedish warship ''Vasa (ship), Vasa'' in 1961. The ''Mary Rose'' site is designated under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swanton, the Choctaw derived their name from an early leader of the Choctaw people. Language The Choctaw language belongs to the Muskogean language family. The Choctaw language was well known among the American frontiersmen of the early 19th century. In 1870, a Christian Missionary and fluent Choctaw speaker Cyrus Byington published a Choctaw Dictionary ''Grammar of the Choctaw Language.'' Revised addit ...

Harold Edgerton
Harold Eugene "Doc" Edgerton (April 6, 1903 – January 4, 1990), also known as Papa Flash, was an American scientist and researcher, a professor of electrical engineering at the Massachusetts Institute of Technology. He is largely credited with transforming the stroboscope from an obscure laboratory instrument into a common device. He also was deeply involved with the development of sonar and deep-sea photography, and his equipment was used in collaboration with Jacques Cousteau in searches for shipwrecks and even the Loch Ness Monster. Biography Early years Edgerton was born in Fremont, Nebraska, on April 6, 1903, the son of Mary Nettie Coe and Frank Eugene Edgerton, a descendant of Samuel Edgerton, the son of Richard Edgerton, one of the founders of Norwich, Connecticut, and Alice Ripley, a great-granddaughter of Governor William Bradford (1590–1657) of the Plymouth Colony and a passenger on the Mayflower.
