Pluragrotta
Pluragrotta is a cave in Rana, Norway. It is the deepest cave in Northern Europe. Most caves in Rana, of which there are some 200, are not suitable for diving. A popular cave diving destination, Pluragrotta attracts more divers than any other cave in Scandinavia. Visibility in the cave waters is high. The cave's passages were formed by the flow of the Plura river over limestone, and the cave system includes marble formations. A number of species have been identified in the cave ecosystem. Diving became possible in Pluragrotta with the damming of lake Kallvatnet in the 1960s. There have been multiple injuries and fatalities among cave divers at the site, which is accessible year-round. Discovery and exploration The damming of lake Kallvatnet in the mid-1960s greatly reduced water flow in the partially subterranean Plura river, making diving possible in the cave. The first known dive in Pluragrotta was done by Svein Grundstrøm and Bjørn Fagertun in 1980. They are belie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jordbrugrotta
Jordbrugrotta is a cave in the upper parts of by the river in Rana municipality in Nordland county in Norway. The cave is named after the farm Jordbrua further down the valley. The cave is situated about two kilometers south of the dam at Kallvatnet. Jordbrugrotta was discovered during the Second World War. In 1949 an attempt to enter via Sprutfossen and into the main system did not succeed. In 1953 Jakob Otnes from NVE described parts of the cave and reported that during the winter they had succeeded in entering 500 meters into the mountain via Sprutfossen. In 1959 an expedition from NTH visited the cave but did not make a report. In 1962 and 1964 the British cave club "Explorer's club" from Haberdasher's Aske's Hatcham School explored Jordbrugrotta. The cave has at least three entrances. One of the entrances is a bit north of Sprutbekken and it is possible to enter while the waterfall of Sprutfossen is small. Another entrance is called Hatcham Hole and enters from west t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plura (river)
Plura is a river in the municipality of Rana, Norway, Rana in Nordland county, Norway. The river begins at the lake Kallvatnet, flows through the Plurdalen valley, and ends up as a tributary to the river Ranelva, about north of the town of Mo i Rana. The river is rich with salmon, trout, and Arctic char. The name comes from the Norwegian verb ''"prula"'' which means "boiling" or "seething". The Plura river flows both over and beneath the ground, and it has the longest subterranean flow in Norway at . Until 1964, Plura was a large river, washing limestone out of the mountain, creating several caves/tunnels down through the Plurdalen valley. Through the Pluragrotta cave, about of water passed each minute. The Kallvatnet dam made the river Plura almost dry, and the water in Pluragrotta cave became standing still like in a Trap (plumbing), water seal.

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...
