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 ...

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. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed LC-130
The Lockheed LC-130 is a ski-equipped United States Air Force variant of the C-130 Hercules used in the Arctic and Antarctic. Ten are currently in service with the 109th Airlift Wing of the New York Air National Guard. Design and development The LC-130 started as a prototype model developed by modifying a ''C-130A'' with skis in 1956. After testing in 1957, 12 additional C-130A models were modified with skis and hydraulics under the designation of ''C-130D''. In 1959 the first four factory equipped, ski-based Hercules were produced under the Navy designation of UV-1L. These C-130s are USAF C-130B models. Later in the program the designation was changed from UV-1L to C-130BL. This designation was again later changed to LC-130F when aircraft nomenclature was standardized for all services by the U. S. Defense Department in 1962. These four aircraft were bought by the Navy Department to support the Navy's Antarctic expedition that was ongoing at the time. The Navy also bought one ...

Antarctic Field Camps
Many Antarctic research stations support satellite field camps which are, in general, seasonal camps. The type of field camp can vary – some are permanent structures used during the annual Antarctic summer, whereas others are little more than tents used to support short term activities. Field camps are used for many things, from logistics (Sky Blu) to dedicated scientific research ( WAIS Divide Field Camp). List of field camps See also *Research stations in Antarctica * Demographics of Antarctica *List of Antarctic expeditions This list of Antarctic expeditions is a chronological list of expeditions involving Antarctica.

Nevada Museum Of Art
The Nevada Museum of Art, is an art museum in Reno, Nevada. Located at 160 West Liberty Street in Reno, it is the only American Alliance of Museums (AAM) accredited art museum in the state of Nevada. The museum has chosen a thematic approach, placing a special emphasis on human interaction with the land and the protection of nature in its collections and exhibitions. In 2003, the Museum moved into a new building designed by architect Will Bruder. Permanent Collections The Museum's Permanent Collection, which consists of more than 2,000 works of 19th through 21st-century art, is divided into four focus areas unified by an overarching focus on natural, built and virtual environments. This thematic, rather than historical or stylistic specialization is a natural outgrowth of the institution's collecting practices over the years and offers varied perspectives on the ways in which humans interact with the environments. "As curator of exhibitions and collections," Ann Wolfe explains, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Methane
Atmospheric methane is the methane present in Earth's atmosphere. Atmospheric methane concentrations are of interest because it is one of the most potent greenhouse gases in Earth's atmosphere. Atmospheric methane is rising. The 20-year global warming potential of methane is 84. See Table 8.7. That is, over a 20-year period, it traps 84 times more heat per mass unit than carbon dioxide (CO2) and 105 times the effect when accounting for aerosol interactions. Global methane concentrations rose from 722 parts per billion (ppb) in pre-industrial times to 1895 ppb by 2021, an increase by a factor of 2.6 and the highest value in at least 800,000 years. Its concentration is higher in the Northern Hemisphere since most sources (both natural and human) are located on land and the Northern Hemisphere has more land mass. The concentrations vary seasonally, with, for example, a minimum in the northern tropics during April−May mainly due to removal by the hydroxyl radical. It remain ...

Abrupt Climate Change
An abrupt climate change occurs when the climate system is forced to transition at a rate that is determined by the climate system energy-balance, and which is more rapid than the rate of change of the external forcing, though it may include sudden forcing events such as meteorite impacts. Abrupt climate change therefore is a variation beyond the variability of a climate. Past events include the end of the Carboniferous Rainforest Collapse, Younger Dryas, Dansgaard-Oeschger events, Heinrich events and possibly also the Paleocene–Eocene Thermal Maximum. The term is also used within the context of climate change to describe sudden climate change that is detectable over the time-scale of a human lifetime, possibly as the result of feedback loops within the climate system or tipping points. Timescales of events described as 'abrupt' may vary dramatically. Changes recorded in the climate of Greenland at the end of the Younger Dryas, as measured by ice-cores, imply a sudden wa ...
