Trevor Chinn (glaciologist)
Trevor James Hill Chinn (9 August 1937 – 20 December 2018) was a New Zealand glaciologist, who conducted extensive surveys of the glaciers of New Zealand's Southern Alps. Early life Growing up near the town of Te Taho (about eight kilometers from Whataroa) in South Westland, near the Franz Josef Glacier, Trevor Chinn was fascinated by water and glaciers at an early age. While at the University of Canterbury Chinn joined the tramping club, and graduated with a BSc in geology. Trevor was the second of four children to Alfred and Myrtle (née Sweney) Chinn. Career During the early 1960s Chinn worked for the North Canterbury Catchment Board, near Christchurch. In his role as field hydrologist, Chinn quickly learned the elements of river gauging and meticulous record keeping. Following a training period with the Ministry of Works, Chinn was invited to apply for a field role carrying out snow surveys on the Tasman Glacier and in the wider Mackenzie Basin. This new job was w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ministry Of Works And Development
The New Zealand Ministry of Works and Development, formerly the Department of Public Works and often referred to as the Public Works Department or PWD, was founded in 1876 and disestablished and privatised in 1988. The Ministry had its own Cabinet-level responsible minister, the Minister of Works or Minister of Public Works. Historically, the state has played an important part in developing the New Zealand economy. For many years the Public Works Department (which became the Ministry of Works in 1948 and the Ministry of Works and Development in 1974) undertook most major construction work in New Zealand, including roads, railways and power stations. After the reform of the state sector, beginning in 1984, the ministry disappeared and its remnants now have to compete for government work. The Ministry of Works and Development was disestablished in 1988 and a Residual Management Unit continued to oversee the Ministry's operations and assets until formally ending in 1993. It was a ...

Tasman Glacier
Haupapa / Tasman Glacier is the largest glacier in New Zealand, and one of several large glaciers which flow south and east towards the Mackenzie Basin from the Southern Alps in New Zealand's South Island. Geography At in length, Tasman Glacier is still New Zealand's longest glacier, despite shrinking considerably from the 1990s onwards. It is as much as wide and thick, and lies entirely within the borders of Aoraki / Mount Cook National Park. The glacier covers an area of and starts at a height of above sea level. Snowfall during the winter and spring seasons may accumulate up to . After the summer melt, may remain in the high altitude glacier head. The Tasman flows south west from Hochstetter Dome and Mount Elie De Beaumont alongside the southern slopes of The Minarets and south along the eastern flank of New Zealand's two highest mountains, Mount Tasman and its higher southern neighbour Aoraki / Mount Cook. Although its upper reaches are snow-covered, rocks carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Hawea
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost .

South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and serv ...

Waimakariri River
The Waimakariri River is one of the largest rivers in Canterbury, on the eastern coast of New Zealand's South Island. It flows for in a generally southeastward direction from the Southern Alps across the Canterbury Plains to the Pacific Ocean. The river rises on the eastern flanks of the Southern Alps, eight kilometres southwest of Arthur's Pass. For much of its upper reaches, the river is braided, with wide shingle beds. As the river approaches the Canterbury Plains, it passes through a belt of mountains, and is forced into a narrow canyon (the Waimakariri Gorge), before reverting to its braided form for its passage across the plains. It enters the Pacific north of Christchurch, near the town of Kaiapoi. Instead of being unoccupied Crown land as are most New Zealand river beds, the bed of the Waimakariri River is vested in the Canterbury Regional Council (Environment Canterbury). Name The name ''Waimakariri'' comes from the Māori words ''wai'', meaning ''water'', and ''makar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the ...

Waitaha River
The Waitaha River, also known as the Mount Cook of rivers, is a river of the West Coast region of New Zealand's South Island. One of the best whitewater rivers in New Zealand (if not the best), the hydroelectricity project has been rejected by the New Zealand government. Waitaha is Māori and it literally means ''wai'' a river or stream ''taha'' to be passed on one side. It was named by the Waitaha, an early South Island iwi (tribe or nation) who named a number of South Island places. It flows northwest from the Bloomfield Range of the Southern Alps, some north of Mount Whitcombe, and reaches the Tasman Sea southwest of Ross. Near the coast, it is crossed by , and just downstream from the bridge, the Kakapotahi River or Little Waitaha River flows into the Waitaha River. The Waitaha River is renowned for gold, both alluvial and from glacial deposition. Coarse gold has been dredged downstream of Morgans Gorge where the river opens into the flats. Several gold mining operations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ablation
Ablation ( la, ablatio – removal) is removal or destruction of something from an object by vaporization, chipping, erosive processes or by other means. Examples of ablative materials are described below, and include spacecraft material for ascent and atmospheric reentry, ice and snow in glaciology, biological tissues in medicine and passive fire protection materials. Artificial intelligence In artificial intelligence (AI), especially machine learning, ablation is the removal of a component of an AI system. The term is by analogy with biology: removal of components of an organism. Biology Biological ablation is the removal of a biological structure or functionality. Genetic ablation is another term for gene silencing, in which gene expression is abolished through the alteration or deletion of genetic sequence information. In cell ablation, individual cells in a population or culture are destroyed or removed. Both can be used as experimental tools, as in loss-of-function ...
