Core Sample
A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample different media under different conditions. More continue to be invented on a regular basis. In the coring process, the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyzed by different techniques and equipment depending on the type of data desired. Core samples can be taken to test the properties of manmade materials, such as concrete, ceramics, some metals and alloys, especially the softer ones. Core samples can also be taken of living things, including human beings, especially of a person's bones for microscopic examination to help diagnose diseases. Methods The compo ...

Research Institutes In New Zealand
Research is " creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpine Fault
The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island (c. 480 km) and forms the boundary between the Pacific Plate and the Indo-Australian Plate. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otago moving South. The average slip rates in the fault's central region are about 38 mm a year, very fast by global standards. The last major earthquake on the Alpine Fault was in c. 1717 AD, and the probability of another one occurring within the next 50 years is estimated at about 75 percent. Geographic extent and plate motion ThPacific Plate and Indo-Australian Plate boundaryforms the Macquarie Fault Zone in the Puysegur Trench off the southwestern corner of the South Island and comes onshore as the Alpine Fault just nort ...

Harold Wellman
Harold William Wellman (25 March 1909 – 28 April 1999) was an English-born New Zealand geologist known for his work on plate tectonics. He is notable for his discovery of South Island's Alpine Fault. Wellman became a Fellow of the Royal Society of New Zealand in 1954, and was awarded the Hector Memorial Medal and Prize in 1957 and the McKay Hammer Award in 1959. Life and career Harold Wellman was born in Devonport, England, to Evan Edward Wellman, an engineer in the Royal Navy, and May Kinglake Hoare. In 1927 his father was deployed at Devonport, Auckland, New Zealand for three years and the family moved to New Zealand. Harold Wellman first worked as a surveyor, but was soon forced to become a gold prospector on the West Coast due to the lack of work available during the depression. In the mid-1930s Wellman began his geological study while working in mineral exploration for the Department of Scientific and Industrial Research. He initially studied at Canterbury University, l ...

Eureka Spurs
The Eureka Spurs () are several rock spurs exposed along the east side of the head of Mariner Glacier, southwest of Mount McCarthy, in Victoria Land. They were so named, after the ancient Greek word eureka, by the Victoria University of Wellington Antarctic Expedition field party to Evans Neve, 1971–72, on the occasion of fossil discoveries made in the area. Thick sections of sedimentary strata of the Spurs Formation are exposed in Eureka Spurs. These outcrops exposed Cambrian submarine channel-fills in the Spurs Formation that exhibit unique meter-scale sedimentary cyclic layers of breccia and diamictite.Kim, Y.H.G., Woo, J., Park, T.Y.S., Kihm, J.H., Lee, J.I. and Choe, M.Y., 2018.

McKelvey Valley
McKelvey Valley () is a valley between the western part of the Olympus Range and the Insel Range, in Victoria Land, Antarctica. It was named by the Victoria University of Wellington Antarctic Expedition (VUWAE) (1958–59) for B.C. McKelvey, a geologist of the Victoria University of Wellington, who, with P.N. Webb, undertook the first geological exploration of this area (1957–58), and was again in Wright Valley The Wright Valley, named for Sir Charles Wright, is the central one of the three large Dry Valleys in the Transantarctic Mountains, located west of McMurdo Sound at approximately .

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 . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer.

Ice Sheet Model
In climate modelling, Ice-sheet models use numerical methods to simulate the evolution, dynamics and thermodynamics of ice sheets, such as the Greenland ice sheet, the Antarctic ice sheet or the large ice sheets on the northern hemisphere during the last glacial period. They are used for a variety of purposes, from studies of the glaciation of Earth over glacial–interglacial cycles in the past to projections of ice-sheet decay under future global warming conditions. History Beginning in the mid-18th Century, investigation into ice sheet behavior began. Since the Journal of Glaciology's founding, physicists have been publishing glacial mechanics. The first 3-D model was applied to the Barnes Ice Cap. In 1988, the first thermodynamically coupled model incorporating ice-shelves, sheet/shelf transition, membrane stress gradients, isotatic bed adjustment and basal sliding using more advanced numerical techniques was developed and applied to the Antarctic ice sheet. This model had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Cores
An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years. Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old. The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core. The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, and the air trapped in tiny bubbles can be analysed to determine the level of atmospheric gases such as carbon dioxide. Since heat flow in a large ice sheet is very slow, the borehole temperature is another indicator of temperature in the past. These data can be combined to find the climate model ...
