Cropmark
Cropmarks or crop marks are a means through which sub-surface archaeological, natural and recent features may be visible from the air or a vantage point on higher ground or a temporary platform. Such marks, along with parch marks, soil marks and frost marks, can reveal buried archaeological sites that are not visible from the ground. Description Crop marks are due to the principle of differential growth. One of the factors controlling the growth of vegetation is the condition of the soil. A buried stone wall, for example, will affect crop growth above it, as its presence channels water away from its area and occupies the space of the more fertile soil. Conversely, a buried ditch, with a fill containing more organic matter than the natural earth, provides much more conducive conditions and water will naturally collect there, nourishing the plants growing above. The differences in conditions will cause some plants to grow more strongly and therefore taller, and others less str ...

Aerial Archaeology
Aerial archaeology is the study of archaeological remains by examining them from a higher altitude. In present day, this is usually achieved by satellite images or through the use of drones. Details Aerial Archaeology involves interpretation and image analysis of photographic (and other kinds of images), in field research to understand archaeological features, sites, and landscapes. It enables exploration and examination of context and large land areas, on a scale unparalleled by other archaeological methods. The AARG (Aerial Archaeology Research Group) boasts that 'more archaeological features have been found worldwide through aerial photography than by any other means of survey'. Aerial archaeological survey combines data collection and data analysis. The umbrella term 'Aerial images' includes traditional aerial photographs, satellite images, multispectral data (which captures image data within specific wavelength ranges across the electromagnetic spectrum) and hyperspectral ...

Shadow Marks
Shadow marks (shadow relief) are a form of Archaeology, archaeological feature visible from the air. Unlike cropmarks, frost marks and soil marks they require upstanding features to work and are therefore more commonly seen in the context of extant sites rather than previously undiscovered buried ones. They are caused by the differences in height on the ground produced by archaeological remains. In the case of ancient, eroded earthworks (engineering), earthworks these differences are often small and they are most apparent when viewed from the air, when the sun is low in the sky. This causes long shadows to be cast by the higher features, which are illuminated from one side by the sun, with dark shadows marking hollows and depressions. Artificial shadow marks can be created easily by constructing a virtual model of a site by merging aerial images (Photogrammetry) and then vectoring in a virtual light source from any direction and at any angle.

Soil Mark
Soil marks are differences in soil colour as a result of archaeological features. They can be seen when a ploughed-out earthwork has left hard dry material of a former bank and damper wetter material from a former ditch. They can also occur when a feature has cut through the top soil to reveal underlying chalk. Soil marks are traces of archaeological features, which are visible in ploughed or harrowed fields, usually where there are restricted periods before the crops grow. The most obvious and occurring trace of soil marks is the color difference to the rest of soil. Depending on the area in the aspect of geology the soil marks can show up as brown against white background or vice versa with even darker against lighter tones. The color of the soil is very important in determining whether or not organic or burnt deposits happened over the soil that would produce a black or red color soil. This allows archaeologists to understand the concept of the artefacts found in the region o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Archaeological Field Survey
In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare, and often in excess of many km2). Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. The surveys may be: (a) ''intrusive'' or ''non-intrusive'', depending on the needs of the survey team (and the risk of destroying archaeological evidence if intrusive methods are used) and; (b) ''extensive'' or ''intensive'', depending on the types of research questions being asked of the landscape in quest ...

Hoar Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase transition, phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Crop Circle
A crop circle, crop formation, or corn circle is a pattern created by flattening a crop, usually a cereal. The term was first coined in the early 1980s by Colin Andrews. Crop circles have been described as all falling "within the range of the sort of thing done in hoaxes" by Taner Edis, professor of physics at Truman State University. Although obscure natural causes or alien origins of crop circles are suggested by fringe theorists, there is no scientific evidence for such explanations, and all crop circles are consistent with human causation. The number of reports of crop circles has substantially increased since the 1970s. There has been scant scientific study of them. Circles in the United Kingdom are not distributed randomly across the landscape but appear near roads, areas of medium to dense population and cultural heritage monuments, such as Stonehenge or Avebury. In 1991, two hoaxers, Doug Bower and Dave Chorley, took credit for having created many circles throughout E ...

Kenneth Joseph
Kenneth is an English given name and surname. The name is an Anglicised form of two entirely different Gaelic personal names: ''Cainnech'' and '' Cináed''. The modern Gaelic form of ''Cainnech'' is ''Coinneach''; the name was derived from a byname meaning "handsome", "comely". A short form of ''Kenneth'' is '' Ken''.

Luftwaffe
The ''Luftwaffe'' () was the aerial-warfare branch of the German ''Wehrmacht'' before and during World War II. Germany's military air arms during World War I, the ''Luftstreitkräfte'' of the Imperial Army and the '' Marine-Fliegerabteilung'' of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the ''Luftwaffe''s existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a ''Luftwaffe'' detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing grou ...

Mucking Excavation
Mucking is an archaeological site near the village of Mucking in southern Essex. The site contains remains dating from the Neolithic to the Middle Ages—a period of some 3,000 years—and the Bronze Age and Anglo-Saxon features are particularly notable.Hamerow, H. 1993 Excavations at Mucking, Volume 2: The Anglo-Saxon Settlement' (English Heritage Archaeological Report 21) Major excavations took place at the site between 1965 and 1978, directed by Margaret Ursula Jones. Covering an area of 18 hectares (44 acres), at the time it was the largest archaeological excavation in Europe, and is the largest excavation ever undertaken in the British Isles. Excavation continued year-round to stay ahead of gravel extraction that was rapidly destroying the site, accumulating an "astonishing" volume of material. Only a fraction of this was analysed or published in Jones' lifetime, and ultimately the bulk of the post-excavation work was left to others. The first volume of a "full publica ...

Venice
Venice ( ; it, Venezia ; vec, Venesia or ) is a city in northeastern Italy and the capital of the Veneto Regions of Italy, region. It is built on a group of 118 small islands that are separated by canals and linked by over 400 bridges. The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po River, Po and the Piave River, Piave rivers (more exactly between the Brenta (river), Brenta and the Sile (river), Sile). In 2020, around 258,685 people resided in greater Venice or the ''Comune di Venezia'', of whom around 55,000 live in the historical island city of Venice (''centro storico'') and the rest on the mainland (''terraferma''). Together with the cities of Padua, Italy, Padua and Treviso, Italy, Treviso, Venice is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million. The name is derived from the ancient Adri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Altinum
Altinum (in Altino, a ''frazione'' of Quarto d'Altino) was an ancient town of the Veneti 15 km SE of modern Treviso, close to the mainland shore of the Lagoon of Venice. It was also close to the mouths of the rivers Dese, Zero and Sile. A flourishing port and trading centre during the Roman period, it was destroyed by Attila the Hun in 452. The town recovered, but was later abandoned when sea-borne sand began to cover it over. Its inhabitants moved to Torcello and other islands of the northern part of the lagoon. Today Altinum is an archaeological area and has a national archaeological museum. Pre-Roman Altinum Altium was a Venetic settlement. The earliest human presence in the area is dated to the 10th century BCE and is related to hunter gatherer groups. The earliest evidence of a settlement nucleus is dated from the mid-8th century to the mid-7th century BCE. In the 7th century BCE the settlement moved slightly to the northwest, in its historical location. A sacred ar ...
