British Mid-Ocean Ridge Initiative
The British Mid-Ocean Ridge Initiative (the BRIDGE Programme) was a multidisciplinary scientific investigation of the creation of the Earth’s crust in the deep oceans. It was funded by the UK’s Natural Environment Research Council ( NERC) from 1993 to 1999. Mid-Ocean ridges Mid-Ocean ridges are active volcanic mountain ranges snaking through the depths of the Earth’s oceans. They occur where the edges of the Earth’s tectonic plates are separating, allowing mantle rock to rise to the seafloor and harden, creating new crust. The addition of this crust can cause ocean basins to widen perpendicular to the ridge. This seafloor spreading is the engine of continental drift. At intervals along the mid-ocean ridges super-heated mineral-rich fluids are vented from the seabed. These hydrothermal vents are populated by animal and bacterial species not found elsewhere on Earth. BRIDGE investigated the geological setting of the ridge, the geochemistry of vent fluids, and ways in wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wormley, Surrey
Wormley is a village in Surrey, England in the parish of Witley, around Witley station, off the A283 Petworth Road about SSW of Godalming. History Expansion from archetypal hamlet Wormley developed primarily as a result of the construction in the 19th century of Witley station, on the Portsmouth Direct line. King Edward's School, Witley once had its own station platform. Former businesses Cooper & Sons Ltd owned the Combelane walking stick factory; this was replaced by houses with small gardens and a light industrial estate. The Institute of Oceanographic Sciences Deacon Laboratory was here from 1952 to 1995, housed in the former Admiralty Signals Establishment building on Brook Road. The only public house, the ''Wood Pigeon'', closed in 2007. Architecture and gardens King Edward's School is a Grade II listed building, the school war memorial is also Grade II listed. Some of the gardens in Wormley were designed by Gertrude Jekyll, who collaborated with Edward Lutyens from h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Oceanography Centre, Southampton
The National Oceanography Centre Southampton (NOCS) is a centre for research, teaching, and technology development in Ocean and Earth science. NOCS was created in 1995 jointly between the University of Southampton and the UK Natural Environment Research Council and is located within the port of Southampton at a purpose-built dockside campus with modern facilities. In 2010 the university and NERC components demerged, and the NERC-managed component became the National Oceanography Centre (NOC – with the Proudman Oceanographic Laboratory in Liverpool). The two components of NOCS continue close collaboration through the jointly run Graduate School, shared research facilities and laboratories, complementary research groups, and many joint research grants and publications. The university component “Ocean and Earth Science, National Oceanography Centre Southampton” (OES) is part of the Faculty of Environmental and Life Sciences, (FELS).

Outsourcing
Outsourcing is an agreement in which one company hires another company to be responsible for a planned or existing activity which otherwise is or could be carried out internally, i.e. in-house, and sometimes involves transferring employees and assets from one firm to another. The term ''outsourcing'', which came from the phrase ''outside resourcing'', originated no later than 1981. The concept, which ''The Economist'' says has "made its presence felt since the time of the Second World War", often involves the contracting of a business process (e.g., payroll processing, claims processing), operational, and/or non-core functions, such as manufacturing, facility management, call center/call center support. The practice of handing over control of public services to private enterprises (privatization), even if conducted on a limited, short-term basis, may also be described as outsourcing. Outsourcing includes both foreign and domestic contracting, and sometimes includes offshoring ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Science
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere, hydrosphere, atmosphere, and geosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields. There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about Earth processes suc ...

Swindon
Swindon () is a town and unitary authority with Borough status in the United Kingdom, borough status in Wiltshire, England. As of the 2021 Census, the population of Swindon was 201,669, making it the largest town in the county. The Swindon unitary authority area had a population of 233,410 as of 2021. Located in South West England, the town lies between Bristol, 35 miles (56 kilometres) to its west, and Reading, Berkshire, Reading, equidistant to its east. Recorded in the 1086 Domesday Book as ''Suindune'', it was a small market town until the mid-19th century, when it was selected as the principal site for the Great Western Railway's repair and maintenance Swindon Works, works, leading to a marked increase in its population. The new town constructed for the railway workers produced forward-looking amenities such as the UK’s first lending library and a ‘cradle-to-grave' health care centre that was later used as a blueprint for the National Health Service, NHS.

Chemical Species
A chemical species is a chemical substance or ensemble composed of chemically identical molecular entity, molecular entities that can explore the same set of molecular energy levels on a characteristic or delineated time scale. These energy levels determine the way the chemical species will interact with others (engaging in chemical bonds, etc.). The species can be an atom, molecule, ion, or radical, and it has a specific chemical name and chemical formula. The term is also applied to a set of chemically identical atomic or molecular structural units in a solid array. In supramolecular chemistry, chemical species are those supramolecular structures whose interactions and associations are brought about via intermolecular bonding and debonding actions, and function to form the basis of this branch of chemistry. For instance: * The chemical species argon is an atom, atomic species of formula Ar; * dioxygen and ozone are different molecule, molecular species, of respective formulas O ...

Black Smoker
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Mantle (Earth)
The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about under the oceans and about under the continents) and ends at the top of the lower mantle at . Temperatures range from approximately at the upper boundary with the crust to approximately at the boundary with the lower mantle. Upper mantle material that has come up onto the surface comprises about 55% olivine, 35% pyroxene, and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth. Seismic structure The density profile through Earth is determined by the velocity of seismic waves. Density increases progressively in each layer, largely due to compression of the rock at increased depths. Abrupt changes in density occur where the material composition changes. The upper mantle begins just beneath the crust and ends at the top of the lower mantle. The upper mantle causes the tectonic plates to move. ...

Magma
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and gas bubbles. Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones, mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by fractional crystallization, contamination with crustal melts, magma mixing, and degassing. Following its ascent through the crust, magma may feed a volcano and be extruded as lava, or it may solidify underground to form an intrusion, such as a ...
