Kendrick Taylor
Kendrick Cashman Taylor, Jr. is a climate change researcher working with ice cores in Greenland and Antarctica. While a Research Professor at the Desert Research Institute in Reno, Nevada, he was the Chief Scientist for the Siple Dome and WAIS Divide ice core projects in Antarctica. He has also done work on near shore clarity at Lake Tahoe and teaching World Vision how to use geophysics to find favorable locations for shallow water wells in West Africa. His ResearcherID is A-3469-2016 and ORCID is 0000-0001-8535-1261. Kendrick Cashman Taylor, Sr. (1922–1995) was an engineer who specialized in vacuum metallurgy Vacuum metallurgy is the field of materials technology that deals with making, shaping, or treating metals in a controlled atmosphere, at pressures significantly less than normal atmospheric pressure.http://processmaterials.com/technology/vacuum-me ..., especially related to depositing thin films on mylar.

Siple Dome
Siple Dome () is an ice dome approximately 100 km wide and 100 km long, located 130 km east of Siple Coast in Antarctica. Charles Bentley and Robert Thomas established a "strain rosette" on this feature to determine ice movement in 1973–74. They referred to the feature as Siple Dome because of its proximity to Siple Coast. Siple Dome ice core The Siple Dome ice core project (79.468° S 112.086° W) was conducted by the United States National Science Foundation. The deepest ice was recovered in 1999 from 974 m, with an age of 97,600 years. It is best known for the poorly-explained steps in water isotopes during the deglacial, which are unique to this core and may indicate a rapid decrease in the surface elevation of the adjoining ice streams during the deglacial and a record of atmospheric carbon dioxide. The Chief Scientist was Kendrick Taylor. Radar surveys of internal ice structure In the 1990s a team from the University of Washington and St Olaf College su ...

WAIS Divide
The WAIS Divide is the ice flow divide on the West Antarctic Ice Sheet (WAIS) which is a linear boundary that separates the region where the ice flows to the Ross Sea, from the region where the ice flows to the Weddell Sea. It is similar to a continental hydrographic divide. Ice core project The WAIS Divide ice core project (West Antarctic Ice Sheet Divide ice core project) investigated past climate changes, ice sheet dynamics and cryobiology. The project was completed by the United States Antarctic Program (USAP) and was funded by the National Science Foundation (NSF). The focus of the project was to develop records spanning the last ~ 80,000 years of the concentration of greenhouse gases in the atmosphere and Antarctic climate, and to do this with the highest possible time resolution. The project is best known for producing records of atmospheric carbon dioxide and methane with high time resolution and dating accuracy. This was accomplished by collecting and analyzing an ice c ...

Ice Core
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 ...

Vacuum Metallurgy
Vacuum metallurgy is the field of materials technology that deals with making, shaping, or treating metals in a controlled atmosphere, at pressures significantly less than normal atmospheric pressure.http://processmaterials.com/technology/vacuum-metallurgy "Vacuum metallurgy", retrieved March 26, 2017 The purpose of vacuum metallurgy is to prevent contamination of metal by gases in the atmosphere. Alternatively, in some processes, a reactive gas may be introduced into the process to become part of the resultant product. Examples of vacuum metallurgy include vacuum degassing of molten steel in steelmaking operations, vacuum deposition of thin metal layers in manufacture of optics and semiconductors, vacuum casting, vacuum arc remelting of alloys, and vacuum induction melting. See also *Electron-beam welding Electron-beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow tog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
