Dersios Sinkhole
The Dersios sinkhole (Greek: Σπηλαιοκαταβόθρα "Ο Δέρσιος" ''Spilaiokatavothra "O Dhersios"'') is a sinkhole in Arcadia, Greece. The sinkhole, which has a depth of , has been known since antiquity and is located towards the north end of the plateau of Palaiochora at a height of 750 m above sea level on mount Parnon. It is about 45 minutes on unsurfaced road from the nearest town of Tyros in the Kynouria region of Arcadia. The sinkhole was first explored in August 1974 to a depth of by a French team (in collaboration with the Hellenic Speleological Society). Since 2003, SELAS caving club in Greece has been exploring the cave, doubling the depth and more than tripling the length of the sinkhole. The new discoveries were made in 2003 by cave diving the first sump A sump is a low space that collects often undesirable liquids such as water or chemicals.

Cave Diving
Cave-diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the search for and recovery of divers or, as in the 2018 Thai cave rescue, other cave users. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave-diving is done using scuba equipment, often in specialised configurations with redundancies such as sidemount or backmounted twinset. Recreational cave-diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves planned decompression stops. A distinction is made by recreational diver training agencies between cave-diving and cavern-diving, where cavern diving is deemed to be diving in those parts of a cave where the exit to open water can be seen by natural light. An arbitrary distance limit to the open water s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinkholes Of Europe
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Caves Of Greece
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms ...

Landforms Of Arcadia, Peloponnese
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siphon
A siphon (from grc, σίφων, síphōn, "pipe, tube", also spelled nonetymologically syphon) is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it flows down the tube under the pull of gravity, then discharging at a level lower than the surface of the reservoir from which it came. There are two leading theories about how siphons cause liquid to flow uphill, against gravity, without being pumped, and powered only by gravity. The traditional theory for centuries was that gravity pulling the liquid down on the exit side of the siphon resulted in reduced pressure at the top of the siphon. Then atmospheric pressure was able to push the liquid from the upper reservoir, up into the reduced pressure at the top of the siphon, like in a baromet ...

Sump (cave)
A sump, or siphon, is a passage in a cave that is submerged under water. A sump may be static, with no inward or outward flow, or active, with continuous through-flow. Static sumps may also be connected underwater to active stream passage. When short in length, a sump may be called a duck, however this can also refer to a section or passage with some (minimal) airspace above the water. Depending on hydrological factors specific to a cave – such as the sea tide, changes in river flow, or the relationship with the local water table – sumps and ducks may fluctuate in water level and depth (and sometimes in length, due to the shape of adjacent passage). Exploration past a sump Diving Short sumps may be passed simply by holding one's breath while ducking through the submerged section (for example, Sump 1 in Swildon's Hole). This is known as "free diving" and can only be attempted if the sump is known to be short and not technically difficult (e.g. constricted or requiring nav ...

Arcadia (regional Unit)
Arcadia ( el, Αρκαδία, ''Arkadía'' ) is one of the regional units of Greece. It is part of the administrative region of Peloponnese. It is in the central and eastern part of the Peloponnese peninsula. It takes its name from the mythological figure Arcas. In Greek mythology, it was the home of the god Pan. In European Renaissance arts, Arcadia was celebrated as an unspoiled, harmonious wilderness. Geography Arcadia is a rural, mountainous regional unit comprising about 18% of the land area of the Peloponnese peninsula. It is the peninsula's largest regional unit. According to the 2011 census, it has about 86,000 inhabitants; its capital, Tripoli, has about 30,000 residents in the city proper, and about 47,500 total in the greater metropolitan area. Arcadia consists partly of farmland, and to a larger extent grassland and degenerated shrubland. It also has three mountain ranges, with forestation mainly at altitudes above 1000 meters: Mainalo, a winter ski resort, situat ...

Kynouria
Cynuria ( – ''Kynouria'' or – ''Kynouriake'') is an ancient district on the eastern coast of the Peloponnese, between the Argolis and Laconia, so called from the Cynurians, one of the most ancient tribes in the peninsula. It was believed to have taken its name from the mythical Cynurus. Location and history Herodotus regarded the Cynurians as autochthones, but at the same time called them Ionians. There can be little doubt, however, that they were Pelasgians; but in consequence of their maritime position, they were regarded as a different race from the Arcadian Pelasgians, and came to be looked upon as Ionians, which was the case with the Pelasgians dwelling upon the coast of the Gulf of Corinth, in the district afterwards called Achaia. They were a semi-barbarous and predatory tribe, dwelling chiefly in the eastern slopes of Mount Parnon; but their exact boundaries cannot be defined, as they were only a tribe, and never formed a political body. At a later time they were alm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyros
Tyre (; ar, صور, translit=Ṣūr; phn, 𐤑𐤓, translit=Ṣūr, Greek ''Tyros'', Τύρος) is a city in Lebanon, one of the List of oldest continuously inhabited cities, oldest continually inhabited cities in the world, though in medieval times for some centuries by just a tiny population. It was one of the earliest Phoenician metropolises and the legendary birthplace of Europa (mythology), Europa, her brothers Cadmus and Phoenix (son of Agenor), Phoenix, as well as Carthage's founder Dido (Elissa). The city has many ancient sites, including the Tyre Hippodrome, and was added as a whole to UNESCO's list of World Heritage Sites in 1984. The historian Ernest Renan noted that "One can call Tyre a city of ruins, built out of ruins". Today Tyre is the fourth largest city in Lebanon after Beirut, Tripoli, Lebanon, Tripoli, and Sidon. It is the capital of the Tyre District in the South Governorate. There were approximately 200,000 inhabitants in the Tyre urban area in 2016, incl ...
