ANDRILL - Showing Features
ANDRILL (ANtarctic DRILLing Project) is a scientific drilling project in Antarctica gathering information about past periods of Climate change (general concept), global warming and cooling. The project involves scientists from Germany, Italy, New Zealand, and the United States. The project is based at McMurdo Station in Antarctica. At two sites in 2006 and 2007, ANDRILL team members drilled through ice, seawater, sediment and rock to a depth over more than and recovered a virtually continuous core record from the present to nearly 20 million years ago. Work In studying the cores, ANDRILL scientists from various Scientific discipline, disciplines are gathering detailed information about past periods of global warming and cooling. A major goal of the project is to significantly improve the understanding of Antarctica's impact on the world's oceans currents and the atmosphere by reconstructing the behavior of Antarctic sea-ice, ice-shelves, glaciers and sea currents over tens of ...

Ross Island
Ross Island is an island formed by four volcanoes in the Ross Sea near the continent of Antarctica, off the coast of Victoria Land in McMurdo Sound. Ross Island lies within the boundaries of Ross Dependency, an area of Antarctica claimed by New Zealand. History Discovery Sir James Ross discovered it in 1840, and it was later named in honour of him by Robert F. Scott. Ross Island was the base for many of the early expeditions to Antarctica. It is the southernmost island reachable by sea. Huts built by Scott's and Shackleton's expeditions are still standing on the island, preserved as historical sites. Today Ross Island is home to New Zealand's Scott Base, and the largest Antarctic settlement, the U.S. Antarctic Program's McMurdo Station. Greenpeace established World Park Base on the island and ran it for five years, from 1987 to 1992. Geography Because of the persistent presence of the ice sheet, the island is sometimes taken to be part of the Antarctic mainland. Its are ...

University Of Nebraska–Lincoln
The University of Nebraska–Lincoln (Nebraska, NU, or UNL) is a public land-grant research university in Lincoln, Nebraska. Chartered in 1869 by the Nebraska Legislature as part of the Morrill Act of 1862, the school was known as the University of Nebraska until 1968, when it absorbed the Municipal University of Omaha to form the University of Nebraska system. It is the state's oldest university and the flagship institution of the state-wide system. The university has been governed by the Board of Regents since 1871, whose members are elected by district to six-year terms. The university is organized into nine colleges: Agricultural Sciences and Natural Resources, Architecture, Arts and Sciences, Business, Education and Human Sciences, Engineering, Fine and Performing Arts, Journalism and Mass Communications, and Law. NU offers over two hundred degrees across its undergraduate, graduate, and doctoral programs. The school also offers programs through the University of Nebr ...

South Pole
The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on Earth and lies antipodally on the opposite side of Earth from the North Pole, at a distance of 12,430 miles (20,004 km) in all directions. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole is distinct from the South Magnetic Pole, the position of which is defined based on Earth's magnetic field. The South Pole is at the centre of the Southern Hemisphere. Geography For most purposes, the Geographic South Pole is defined as the southern point of the two points where Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, Earth's axis of rotat ...

Daily Nebraskan
''The Daily Nebraskan'', established in 1871 as the ''Monthly Hesperian Student'', is the student newspaper of the University of Nebraska–Lincoln. Although many journalism students are on staff, the ''Daily Nebraskan'' is independent of the university's College of Journalism and Mass Communications. The newspaper is entirely student-produced and managed, and has a professional general manager, Allen Vaughan, who joined in July 2019 after the retirement of Dan Shattil, who retired in October 2019 after 37 years at the helm. The paper publishes every school day during the fall and spring semesters, with the exceptions of the Tuesday before Thanksgiving break and the last four days of finals week. It publishes weekly during summer sessions. The newspaper covers campus and Lincoln news, along with arts, entertainment, and sports. There is also an opinion page featuring student columnists. In addition, other articles published include the 1948 Nebraska parking riots, the campus strik ...

David Harwood
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David c ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between lati ...

Sedimentologist
Sedimentology encompasses the study of modern sediments such as sand, silt, and clay, and the processes that result in their formation (erosion and weathering), transport, deposition and diagenesis. Sedimentologists apply their understanding of modern processes to interpret geologic history through observations of sedimentary rocks and sedimentary structures. Sedimentary rocks cover up to 75% of the Earth's surface, record much of the Earth's history, and harbor the fossil record. Sedimentology is closely linked to stratigraphy, the study of the physical and temporal relationships between rock layers or strata. The premise that the processes affecting the earth today are the same as in the past is the basis for determining how sedimentary features in the rock record were formed. By comparing similar features today to features in the rock record—for example, by comparing modern sand dunes to dunes preserved in ancient aeolian sandstones—geologists reconstruct past environm ...

Joides Resolution
295px, Drillship ''JOIDES Resolution'' in 1988 The riserless research vessel ''JOIDES Resolution'' (Joint Oceanographic Institutions for Deep Earth Sampling), often referred to as the JR, is one of the scientific drilling ships used by the International Ocean Discovery Program (IODP), an international, multi-drilling platform research program. The JR was previously the main research ship used during the Ocean Drilling Program (ODP) and was used along with the Japanese drilling vessel ''Chikyu'' and other mission-specific drilling platforms throughout the Integrated Ocean Drilling Program. She is the successor of ''Glomar Challenger''. The ship was first launched in 1978 as ''Sedco/BP 471'', an oil exploration vessel. It was converted for scientific use 6 years later in 1984 and began working as the main research ship for ODP in January 1985. The JR was modernized during 2007–2008 and returned to active service in February 2009 following an extensive renovation of her laboratory f ...

Ocean Current
An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements. An ocean current flows for great distances and together they create the global conveyor belt, which plays a dominant role in determining the climate of many of Earth’s regions. More specifically, ocean currents influence the temperature of the regions through which they travel. For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them. Perhaps the most striking example is the Gulf Stream, which makes northwest Europe much more temperate for its high latitude compared to other areas at ...
