Bjorøy Tunnel
The Bjorøy Tunnel () is a subsea road tunnel in Vestland county, Norway. The tunnel is part of the Norwegian County Road 5236 which connects the island of Bjorøy in the municipality of Øygarden to the mainland near Håkonshella and Hilleren in the city-municipality of Bergen. It crosses underneath the Vatlestraumen strait, reaching below mean sea level. It serves as a fixed link for the 900 residents of the islands of Bjorøy and Tyssøy as well as a large number of cottage owners who vacation on the islands. The first proposal was launched in 1980, and construction started on 29 September 1993. There were severe problems because the tunneling encountered an area of sandstone, causing a year's delay. The total construction cost was . It opened on 7 May 1996 and remained a toll road until 29 January 2005. Specifications The Bjorøy Tunnel is a subsea tunnel which runs below the Vatlestraumen strait between the island of Bjorøy and the mainland of Bergen. It carrie ...

Norwegian Public Safety Radio
The Norwegian Public Safety Network ( literally ''Emergency Network'') is a public safety network system based on Terrestrial Trunked Radio (TETRA). Nødnett is implemented by the Directorate for Emergency Communication (). The network is primarily used for internal and interdisciplinary communication by the police, fire departments and health services. Nødnett is also used by several organisations participating in rescue and emergency work. Planning of the network started in 1995 and in 2006 the contract to build it was awarded to Nokia Siemens Networks. As Nokia Siemens Networks was unable to complete the contract, it was passed on to Motorola Solutions in 2012. The critical infrastructure of Nødnett was finished and was operational in all districts of mainland Norway by December 1, 2015. The network replaced nearly 300 local and regional networks which operated independently for the fire, police and healthcare agencies. Nødnett allows functionality such as authentication ...

Bjorøy Tunnel Map 2
Bjorøyna or Bjorøy is an island in Øygarden Municipality in Vestland county, Norway. The island is located south of the island of Litlesotra, west of the Bergen Peninsula, north of the island of Tyssøyna, and east of the island of Sotra. Bjorøy is connected to the mainland city of Bergen by a subsea road tunnel called the Bjorøy Tunnel. Bjorøyis also connected to the small island of Tyssøy in the neighboring Sund municipality by a bridge. Bjorøy has 878 inhabitants (September 2012), and several hundred vacation cabins. History Due to its favourable location, proximity to Bergen, and the construction of the tunnel, the island has in recent years seen strong population growth. To prevent uncontrolled development, a building ban was instituted in 2007 but was later removed. The ban was instituted after a non-legally binding cap that only allowed ten new houses to be built on the island per year. The purpose was to ensure that the population growth did not surpass the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike And Dip
In geology, strike and dip is a measurement convention used to describe the plane orientation or Attitude (geometry), attitude of a Plane (geometry), planar Geology, geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle) measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geological map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the feature's dip by recording the inclination pe ...

Bedding (geology)
In geology, a bed is a layer of sediment, sedimentary rock, or volcanic rock "bounded above and below by more or less well-defined bedding surfaces".Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds., 2005. ''Glossary of Geology'' (5th ed.). Alexandria, Virginia; American Geological Institute. p 61. A bedding surface or bedding plane is respectively a curved surface or plane that visibly separates each successive bed (of the same or different lithology) from the preceding or following bed. In cross sections, bedding surfaces or planes are often called bedding contacts. Within conformable successions, each bedding surface acted as the depositional surface for the accumulation of younger sediment. Definitions Specifically in sedimentology, a bed can be defined in one of two major ways.Davies, N.S., and Shillito, A.P. 2021, ''True substrates: the exceptional resolution and unexceptional preservation of deep time snapshots on bedding surfaces.'' ''Sedimentology.'' publish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Oxfordian (stage)
The Oxfordian is, in the International Commission on Stratigraphy, ICS' geologic timescale, the earliest age (geology), age of the Late Jurassic epoch (geology), Epoch, or the lowest stage (stratigraphy), stage of the Upper Jurassic series (stratigraphy), Series. It spans the time between 161.5 ± 1.0 Annum#SI prefix multipliers, Ma and 154.8 ± 0.8 Ma (million years ago). The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian. Stratigraphic definitions The Oxfordian Stage was called "Clunch Clay and Shale" by William Smith (1815–1816); in 1818 W. Buckland described them under the unwieldy title "Oxford, Forest or Fen Clay". The term Oxfordian was introduced by Alcide d'Orbigny in 1844. The name is derived from the English city of Oxford, where the beds are well developed, but they crop out almost continuously from Dorset to the coast of Yorkshire, generally forming low, broad valleys. They are well exposed at Weymouth, Dorset, Weymouth, Oxford, Bedfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gneiss
Gneiss (pronounced ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. This rock is formed under pressures ranging from 2 to 15 kbar, sometimes even more, and temperatures over 300 °C (572 °F). Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct Cleavage (geology), cleavage. Gneisses are common in the ancient crust of Continental Shield, continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description image:Orthogneiss Geopark.jpg, Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct Cleavage (geology), cleavage. In other words, it i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conglomerate (geology)
Conglomerate () is a sedimentary rock made up of rounded gravel-sized pieces of rock surrounded by finer-grained sediments (such as sand, silt, or clay). The larger fragments within conglomerate are called clasts, while the finer sediment surrounding the clasts is called the matrix. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form when rounded gravels deposited by water or glaciers become solidified and cemented by pressure over time. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. They are closely related to sandstones in origin, and exhibit many of the same types of sedimentary structures, such as tabular and trough cross-bedding and graded bedding.Boggs, S. (2006) ''Principles of Sedimentology and Stratigraphy.'', 2nd ed. Prentice Hall, New York. 662 pp. Friedman, G.M. (2003) ''Classification of sediments and s ...

Breccia
Breccia ( , ; ) is a rock composed of large angular broken fragments of minerals or Rock (geology), rocks cementation (geology), cemented together by a fine-grained matrix (geology), matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, fault (geology), fault or tectonics, tectonic breccia, igneous breccia, Impact event, impact breccia, and Hydrothermal circulation, hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like Conglomerate (geology), conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from Conglomerate (geol ...
