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 may be used to conduct surveys for marine archaeology; 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 sub-bottom profiler data, thus providing a glimpse of the shallow structure of the seabed. Side-scan sonar is also used for fisheries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solid-state Drive
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks. SSD also has rich internal parallelism for data processing. In comparison to hard disk drives and similar electromechanical media which use moving parts, SSDs are typically more resistant to physical shock, run silently, and have higher input/output rates and lower latency. SSDs store data in semiconductor cells. cells can contain between 1 and 4 bits of data. SSD storage devices vary in their properties according to the number of bits stored in each cell, with single-bit cells ("Single Level Cells" or "SLC ...

Asdic
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 extrem ...

Natural Environment Research Council
The Natural Environment Research Council (NERC) is a British research council that supports research, training and knowledge transfer activities in the environmental sciences. History NERC began in 1965 when several environmental (mainly geographic) research organisations (including Nature Conservancy which became the Nature Conservancy Council in 1973 and was divided up in 1991) were brought under the one umbrella organisation. When most research councils were re-organised in 1994, it had new responsibilities – Earth observation and science-developed archaeology. Collaboration between research councils increased in 2002 when Research Councils UK was formed.

National Oceanography Centre
The National Oceanography Centre (NOC) is a marine science research and technology institution based on two sites in Southampton and Liverpool, United Kingdom. It is the UK’s largest institution for integrated sea level science, coastal and deep ocean research and technology development. From 1 November 2019 the NOC began operating as an independent self-governing organisation – a charitable company limited by guarantee. The centre was set up to work in close partnership with institutions across the UK marine science community to address key science challenges, including sea level change, the oceans’ role in climate change, predicting and simulating the behaviour of the oceans through computer modelling, the future of the Arctic Ocean and long-term monitoring technologies. Marine science national capability The NOC provides the bulk of the UK’s capability to meet the needs of the country’s marine research community. National marine capability provided by the NOC ...

Wreck Of The RMS Titanic
The wreck of the RMS ''Titanic'' lies at a depth of about , about south-southeast of 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 hitting the sea floor. In contrast, the stern is completely ruined. A debris field around the wreck contains hundreds of thousands of items spilled from the ship as she sank. The bodies of the passengers and crew would have also been distributed across the sea bed, but have since been consumed by other organisms. sank in 1912, when it collided with an iceberg during its maiden voyage. Numerous expeditions tried using sonar to map the sea bed in the hope of finding it, but were unsuccessful. 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. The wreck has been the focus of intense interest and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIND Technology, Inc
The mind is the set of faculties responsible for all mental phenomena. Often the term is also identified with the phenomena themselves. These faculties include thought, imagination, memory, will, and sensation. They are responsible for various mental phenomena, like perception, pain experience, belief, desire, intention, and emotion. Various overlapping classifications of mental phenomena have been proposed. Important distinctions group them according to whether they are ''sensory'', ''propositional'', ''intentional'', ''conscious'', or ''occurrent''. Minds were traditionally understood as substances but it is more common in the contemporary perspective to conceive them as properties or capacities possessed by humans and higher animals. Various competing definitions of the exact nature of the mind or mentality have been proposed. ''Epistemic definitions'' focus on the privileged epistemic access the subject has to these states. ''Consciousness-based approaches'' give primacy to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 studying for an En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
