Ma'agan Michael Ship
The Ma'agan Michael Ship () is a well-preserved 5th-century BCE boat discovered off the coast of Kibbutz Ma'agan Michael, Israel, in 1985. The ship was excavated and its timber immersed in preservation tanks at the University of Haifa, undergoing a seven-year process of impregnation by heated polyethylene glycol (PEG). In March 1999, the boat was reassembled and transferred to a dedicated wing built at the Hecht Museum, on the grounds of the university. The boat has provided researchers with insights into ancient methods of shipbuilding and the evolution of anchors. Discovery and excavation In the autumn of 1985, Ami Eshel, a member of Ma'agan Michael, discovered the wreck while diving off the coast of the kibbutz, 35 km south of Haifa. 75 metres off the coast Eshel spotted rocks uncharacteristic of the Levantine coast next to pieces of wood and pottery sherds, and alerted the Israel Antiquities Authority and the Centre for Maritime Studies at the University of Haifa.

Magmatic
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and gas bubbles. Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones, mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by fractional crystallization, contamination with crustal melts, magma mixing, and degassing. Following its ascent through the crust, magma may feed a volcano and be extruded as lava, or it may solidify underground to form an intrusion, such as a ...

Ma'agan Michael Ancient Ship 002
Ma'agan ( he, מַעֲגָן, lit. "Harbour") is a kibbutz in northern Israel. Located on the southern shore of the Sea of Galilee, it falls under the jurisdiction of Emek HaYarden Regional Council. In it had a population of . History The village was founded in 1949 by immigrants from Transylvania on land that had belonged to the Arab village of Samakh, which was depopulated in 1948. Notable residents include Ami Ayalon, who grew up in the kibbutz. Due to the fact it was situated in the Israel–Syria demilitarised zone under the 1949 Armistice Agreements, Ma'agan was claimed by Syria as its territory during negotiations for a peace agreement in the 1990s. The Israeli government rejected the claims, as it would have led to Syria having territory west of the 1923 border between Mandatory Palestine and the French Mandate of Syria The Mandate for Syria and the Lebanon (french: Mandat pour la Syrie et le Liban; ar, الانتداب الفرنسي على سوريا ولبنان, ...

Sharpening Stone
Sharpening stones, or whetstones, are used to sharpen the edges of steel tools such as knives through grinding and honing. Such stones come in a wide range of shapes, sizes, and material compositions. They may be flat, for working flat edges, or shaped for more complex edges, such as those associated with some wood carving or woodturning tools. They may be composed of natural quarried material or from man-made material. They come in various grades, which refer to the grit size of the abrasive particles in the stone. (Grit size is given as a number, which indicates the spatial density of the particles; a higher number denotes a higher density and therefore smaller particles, which give a finer finish to the surface of the sharpened object.) Stones intended for use on a workbench are called bench stones, while small, portable ones, whose size makes it hard to draw large blades uniformly over them, especially “in the field,” are called pocket stones. Often whetstones are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treenail
A treenail, also trenail, trennel, or trunnel, is a wooden peg, pin, or dowel used to fasten pieces of wood together, especially in timber frames, covered bridges, wooden shipbuilding and boat building. It is driven into a hole bored through two (or more) pieces of structural wood (mortise and tenon). History and general use The use of wood as a tenon can be traced back over 7,000 years, as archaeologist have found traces of wood nails in the excavation of early Germanic sites. Trenails are extremely economical and readily available, making them a common early building material. Black Locust is a favorite wood when making trunnels in shipbuilding in North America and English Oak in Europe due to their strength and rot resistance, while red oak is typical in buildings. Traditionally treenails and pegs were made by splitting bolts of wood with a froe and shaping them with a drawknife on a shaving horse. Treenails are cut from a single piece of wood and perform well because of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipworm
The shipworms are marine bivalve molluscs in the family Teredinidae: a group of saltwater clams with long, soft, naked bodies. They are notorious for boring into (and commonly eventually destroying) wood that is immersed in sea water, including such structures as wooden piers, docks and ships; they drill passages by means of a pair of very small shells (“valves”) borne at one end, with which they rasp their way through. Sometimes called "termites of the sea", they also are known as " Teredo worms" or simply Teredo (from grc, τερηδών, , translit=terēdṓn, lit=wood-worm via ). Carl Linnaeus assigned the common name '' Teredo'' to the best-known genus of shipworms in the 10th edition of his taxonomic ''magnum opus'', '' Systema Naturæ'' (1758). Description Removed from its burrow, the fully grown teredo ranges from several centimetres to about a metre in length, depending on the species. The body is cylindrical, slender, naked and superficially vermiform, meaning "w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False Keel
The false keel was a timber, forming part of the hull of a wooden sailing ship. Typically thick for a 74-gun ship in the 19th century, the false keel was constructed in several pieces, which were scarfed together, and attached to the underside of the keel The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in Br ... by iron staples. The false keel was intended to protect the main keel from damage, and also protect the heads of the bolts holding the main keel together. The false keel could easily be replaced when it became damaged. See also * Worm shoe References {{Reflist Sailing ship components Shipbuilding ...

Aleppo Pine
''Pinus halepensis'', commonly known as the Aleppo pine, also known as the Jerusalem pine, is a pine native to the Mediterranean region. Description ''Pinus halepensis'' is a small to medium-sized tree, tall, with a trunk diameter up to , exceptionally up to . The bark is orange-red, thick, and deeply fissured at the base of the trunk, and thin and flaky in the upper crown. The leaves ('needles') are very slender, long, distinctly yellowish green, and produced in pairs (rarely a few in threes). The cones are narrow conic, long and broad at the base when closed, green at first, ripening glossy red-brown when 24 months old. They open slowly over the next few years, a process quickened if they are exposed to heat such as in forest fires. The cones open wide to allow the seeds to disperse. The seeds are long, with a wing, and are wind- dispersed.Nahal, I. (1962). Le Pin d'Alep (''Pinus halepensis'' Miller). Étude taxonomique, phytogéographique, écologique et sylvicole. ' ...

Cyprus
Cyprus ; tr, Kıbrıs (), officially the Republic of Cyprus,, , lit: Republic of Cyprus is an island country located south of the Anatolian Peninsula in the eastern Mediterranean Sea. Its continental position is disputed; while it is geographically in Western Asia, its cultural ties and geopolitics are overwhelmingly Southern European. Cyprus is the third-largest and third-most populous island in the Mediterranean. It is located north of Egypt, east of Greece, south of Turkey, and west of Lebanon and Syria. Its capital and largest city is Nicosia. The northeast portion of the island is ''de facto'' governed by the self-declared Turkish Republic of Northern Cyprus, which was established after the 1974 invasion and which is recognised as a country only by Turkey. The earliest known human activity on the island dates to around the 10th millennium BC. Archaeological remains include the well-preserved ruins from the Hellenistic period such as Salamis and Kourion, and Cypr ...

Kouris River
Kouris River (Greek Κούρης; Turkish Kuris) is a waterway in Cyprus. Measuring in length, it originates on the south part of the Troodos Mountains, traverses Limassol District, and reaches the sea at Kourion. Not much of the river exists in the lower reaches of its course after the building of the Kouris Dam in the 1980s. This had to effect of enlarging the river's northern basin. Erimi is situated on the river's eastern side, while Kantou is on the western portion. Episkopi, built atop Kourion, is situated near the river's western bank. Luigi Palma di Cesnola Luigi Palma di Cesnola (July 29, 1832 – November 20, 1904), an Italian-American soldier, diplomat and amateur archaeologist, was born in Rivarolo Canavese, near Turin. He received the Medal of Honor for his actions during the American Civil Wa ... explored the area around the river's mouth and reported on it the 1870s.

Gabbro
Gabbro () is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges. Gabbro is also found as plutons associated with continental volcanism. Due to its variant nature, the term ''gabbro'' may be applied loosely to a wide range of intrusive rocks, many of which are merely "gabbroic". By rough analogy, gabbro is to basalt as granite is to rhyolite. Etymology The term "gabbro" was used in the 1760s to name a set of rock types that were found in the ophiolites of the Apennine Mountains in Italy. It was named after Gabbro, a hamlet near Rosignano Marittimo in Tuscany. Then, in 1809, the German geologist Christian Leopold von Buch used the term more restrictively in his descri ...
