Dragon's Breath Cave
Dragon's Breath Cave was discovered by Roger Ellis during a caving expedition to the area in 1986. The cave is located northwest of Grootfontein in the Otjozondjupa Region of Namibia. It is named for the moist air rising from its entrance which resembled the breath of a Dragon. The cave contains the world's largest non- subglacial underground lake, with an area of almost . The lake is located around below the surface. Its total depth is . Although it has been reported that the rare fish species, '' Clarias cavernicola'', lives in the lake in the Dragon's Breath Cave, this is an error. It is only known from the nearby Aigamas Cave. Martyn Farr records in his book "The Darkness Beckons" the exploration of the cave by a team of divers and cavers lead by Roger Ellis and Charles Maxwell of the South African Spelaeological Association a year after the cave was identified in 1986 by cavers as being of significant size.

Otjozondjupa Region
Otjozondjupa is one of the fourteen regions of Namibia. Its capital is Otjiwarongo. The region further contains the municipalities of Okahandja and Grootfontein and the towns Okakarara and Otavi. , Otjozondjupa had 97,945 registered voters. Geography A landmark within this region is the Waterberg Plateau Park. Twenty four kilometres west of Grootfontein lies the huge Hoba meteorite. At over 60 tons, it is the largest known meteorite on Earth, as well as being the largest naturally occurring mass of iron known to exist on the planet's surface. In the east, Otjozondjupa borders the North-West District of Botswana. Domestically, it borders more regions than any other region of Namibia: *Omaheke – southeast *Khomas – south *Erongo – southwest * Kunene – northwest *Oshikoto – north * Kavango – northeast Economy and infrastructure Otjiwarongo, Grootfontein, Otavi, and Okahandja are linked by rail and by the main B1 and B8 trunk roads running from south to north.

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subglacial Lake
A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where gravitational pressure decreases the pressure melting point of ice. Over time, the overlying ice gradually melts at a rate of a few millimeters per year. Meltwater flows from regions of high to low hydraulic pressure under the ice and pools, creating a body of liquid water that can be isolated from the external environment for millions of years. Since the first discoveries of subglacial lakes under the Antarctic Ice Sheet, more than 400 subglacial lakes have been discovered in Antarctica, beneath the Greenland Ice Sheet, and under Iceland's Vatnajökull ice cap. Subglacial lakes contain a substantial proportion of Earth's liquid freshwater, with the volume of Antarctic subglacial lakes alone estimated to be about 10,000 km3, or about 15% of all liquid freshwater on Earth.

Underground Lake
An underground lake or subterranean lake is a lake underneath the surface of the Earth. Most naturally occurring underground lakes are found in areas of Karst topography, where limestone or other soluble rock has been weathered away, leaving a cave where water can flow and accumulate. Natural underground lakes are an uncommon hydrogeological feature. More often, groundwater gathers in formations such as aquifers or springs. The largest subterranean lake in the world is in Dragon's Breath Cave in Namibia, with an area of almost ; the second largest is The Lost Sea, located inside Craighead Caverns in Tennessee, United States, with an area of Characteristics In general terms, an underground lake is any body of water that is similar in size to a surface lake and exists mostly or entirely underground; though, a precise scientific definition of what may be considered a lake is not yet well-established. Underground lakes could be classified as either “lakes” or "ponds", de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarias Cavernicola
The cave catfish (''Clarias cavernicola'') is a critically endangered species of airbreathing catfish. Listed as Critically Endangered (CR B1+2c, E v2.3) This cavefish is only known to live in the Aigamas cave, Otjozondjupa region, Namibia. It has also been reported from the nearby Dragon's Breath Cave. The golden cave catfish lack pigmentation and are up to 16.1 cm (6.3 inches) in standard length. They have very small eyes that are covered with skin, and are probably effectively blind. They feed on detritus and invertebrates that fall into the lake in which they live. The population is estimated at 200–400 individuals. Little is known about its reproduction, and attempts to breed it in captivity have failed. The population is threatened by chance events and water extraction from the cave lake, which has resulted in a drop of the water level. It is the only known cavefish in mainland Southern Africa.Aldemaro, R., editor (2001). The Biology of Hypogean Fishes. Developments ...

Aigamas Cave
Namibia, a country in south-western Africa, has a total of 124 known caves, 41 of which are situated in the Otjozondjupa Region. In several of these caves research has been done and published in various journals, but of a variety of caves the location is not commonly known, as the information got lost over the years. Some locations are also deliberately kept secret to protect the caves. History The caves known to local people were reported by early explorers and travelers. The caves of Namibia are not reported for their beauty, but for their practical and curiosity reasons.NamibWeb (2012)History of caves in NamibiaRetrieved 31 July 2012 A very common belief is that caves were used as shelter places by the San people (Bushmen). However, San did not use caves to shelter in, as most caves of Namibia have vertical entrances and also are situated on top of elevations. Caves were only used when they were accessible and allowed observation over approaching and surrounding area and also r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossil Water
Fossil water or paleowater is an ancient body of water that has been contained in some undisturbed space, typically groundwater in an aquifer, for millennia. Other types of fossil water can include subglacial lakes, such as Antarctica's Lake Vostok, and even ancient water on other planets. UNESCO defines ''fossil groundwater'' as Determining the time since water infiltrated usually involves analyzing isotopic signatures. Determining "fossil" status—whether or not that particular water has occupied that particular space since the distant past—involves modeling the flow, recharge, and losses of aquifers, which can involve significant uncertainty. Some aquifers are hundreds of meters deep and underlie vast areas of land. Research techniques in the field are developing quickly and the scientific knowledge base is growing. In the cases of many aquifers, research is lacking or disputed as to the age of the water and the behavior of the water inside the aquifer. Renewability Lar ...
