Asherah (submarine)
''Asherah'' was the first commercially built American research submersible, owned by the University of Pennsylvania and used by archaeologist George F. Bass to examine underwater sites. It was named after Asherah, an ancient Semitic goddess known as "she who treads on the sea". The two-person submarine was commissioned in 1963, built by the Electric Boat Division of General Dynamics in Groton, Connecticut, and launched on May 28, 1964. Asherah was 16 feet long, weighed 4.5 tons, and could move at up to 4 knots, powered by rechargeable batteries. She could dive to a depth of . Asherah was used to search for and map wrecks. She was also used to develop a new system of stereoscopy, allowing an excavation site to be mapped in three dimensions, and allowed Bass to become the first to use side-scanning sonar to locate a shipwreck. In 1967, under Bass' direction, ''Asherah'' was used to photograph an ancient Byzantine shipwreck at a depth of 285 feet near Yassi Ada island, off the c ...

The summer of 1614 was the first time that the Pequots encountered white settl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submersible
A submersible is a small watercraft designed to operate underwater. The term "submersible" is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully self-sufficient craft, capable of independent cruising with its own power supply and air renewal system, whereas a submersible is usually supported by a nearby ship, surface vessel, very large floating structure, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word "submarine" may be used to describe a craft that is by the technical definition actually a submersible. There are many types of submersibles, including both crewed and uncrewed craft, otherwise known as remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs). Submersibles have many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance and recovery, and underwater videography. Histo ...

After graduating high school he began studying for an En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Semitic Religion
Ancient Semitic religion encompasses the polytheistic religions of the Semitic peoples from the ancient Near East and Northeast Africa. Since the term ''Semitic'' itself represents a rough category when referring to cultures, as opposed to languages, the definitive bounds of the term "ancient Semitic religion" are only approximate. Semitic traditions and their pantheons fall into regional categories: Canaanite religions of the Levant including among them the polytheistic ancient Hebrew religion of the Israelites; the Sumerian–inspired Babylonian religion of Mesopotamia; the religion of Carthage; and Arabian polytheism. Semitic polytheism possibly transitioned into Abrahamic monotheism by way of the god El, whose name "El" אל, or ''elohim'' אֱלֹהִים is a word for "god" in Hebrew, cognate to Arabic ''ʼilāh'' إله, which means god. Akkad, Assyria and Babylonia When the five planets visible to the naked eye were identified, they were associated with the ...

Connecticut
Connecticut () is the southernmost state in the New England region of the Northeastern United States. It is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Its capital is Hartford and its most populous city is Bridgeport. Historically the state is part of New England as well as the tri-state area with New York and New Jersey. The state is named for the Connecticut River which approximately bisects the state. The word "Connecticut" is derived from various anglicized spellings of "Quinnetuket”, a Mohegan-Pequot word for "long tidal river". Connecticut's first European settlers were Dutchmen who established a small, short-lived settlement called House of Hope in Hartford at the confluence of the Park and Connecticut Rivers. Half of Connecticut was initially claimed by the Dutch colony New Netherland, which included much of the land between the Connecticut and Delaware Rivers, although the firs ...

Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye mov ...

Side-scanning 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] |
