Fjords Of Rogaland
In physical geography, a fjord (also spelled fiord in New Zealand English; ) is a long, narrow sea inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Antarctica, the Arctic, and surrounding landmasses of the northern and southern hemispheres. Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjords when flooded by the ocean. Thresholds above sea level create freshwater lakes. Glacial melting is accompanied by the rebounding of Earth's crust as the ice load and eroded sediment is removed (also called isostasy or ...

Geirangerfjord (6-2007)
or is a fjord in the Sunnmøre region of Møre og Romsdal county, Norway. It is located entirely in Stranda Municipality. It is a branch off the Sunnylvsfjorden, which itself is a branch off the Storfjorden (). The small village of Geiranger is located at the end of the fjord where the Geirangelva river empties into it. The fjord The fjord is one of Norway's most visited tourist sites. In 2005, it was listed as a UNESCO World Heritage Site, jointly with the Nærøyfjorden as the " West Norwegian Fjords" site. This status was challenged by the disputed plans to build power lines across the fjord. The Geiranger - Hellesylt Ferry, a car ferry which doubles as a sightseeing trip, is operated by Fjord1 Nordvestlandske. It runs lengthwise along the fjord between the small towns of Geiranger and Hellesylt. The fjord is scheduled to require zero-emissions ships in 2026. Along the fjord's sides there lie a number of now-abandoned farms. Some restoration has been made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overdeepening
Overdeepening is a characteristic of Depression (geology), basins and valleys eroded by glaciers. An overdeepened valley profile is often eroded to depths which are hundreds of metres below the lowest continuous surface line (the thalweg) along a valley or watercourse. This phenomenon is observed under modern day glaciers, in salt-water fjords and fresh-water lakes remaining after glaciers melt, as well as in tunnel valleys which are partially or totally filled with sediment. When the Channel (geography), channel produced by a glacier is filled with debris, the subsurface Geomorphology, geomorphic structure is found to be erosionally cut into bedrock and subsequently filled by sediments. These overdeepened cuts into bedrock structures can reach a depth of several hundred metres below the valley floor. Overdeepened fjords and lakes have significant economic value as harbours and fisheries. Overdeepened basins and valleys filled with sediment (termed tunnel valleys) are of particular ...

Jens Esmark
Jens Esmark (31 January 1763 – 26 January 1839) was a Danish-Norwegian professor of mineralogy who contributed to many of the initial discoveries and conceptual analyses of glaciers, specifically the concept that glaciers had covered larger areas in the past. Biography Jens Esmark was born in Houlbjerg in Århus, Denmark. Esmark moved to Norway to the silver mining community of Kongsberg. He studied at the local mining academy. He completed his subsequent studies in Copenhagen and was accepted as a surveyor. Starting in 1797, Esmark was employed as a lecturer in mineralogy at the Kongsberg Mining Academy. In 1814, Esmark became Norway's first professor of geology as a professor of geology at the University of Oslo, and was described as "a pioneer in glacial geology", by professor of Quaternary geology and Glaciology Bjørn G. Andersen. In 1798, Esmark was the first person to ascend Snøhetta, highest in the mountain range Dovrefjell in southern Norway. The same yea ...

Drammensfjorden
Drammensfjord () is a fjord in along the border of Akershus and Buskerud counties in Norway that connects to Ytre Oslofjord on the west side. It stretches about to the north and northeast. The Drammenselva river discharges into the head of the fjord. The fjord shares its name with the city of Drammen, which is located at the head of the fjord. Drammen Municipality is located on its west and north sides. The land on the east side of the fjord is called ''Hurumhalvøya'' or the Hurum peninsula and this is located in Asker Municipality. The peninsula lies between the Drammensfjord and the Oslofjord. The fjord narrows to a strait at Svelvik on the west side and Verket in Asker on the east side. The strait is crossed by an automobile ferry. This narrowing, some broad and deep, combined with the large freshwater inflow from the river Drammenselva (one of Norway's largest rivers) and from the river Lierelva, results in the water north of the strait being brackish.

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or " tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saltstraumen
or is a small strait with one of the strongest Tide, tidal currents in the world. It is located in Bodø Municipality in Nordland county, Norway. It is located about southeast of the Bodø (town), town of Bodø. The narrow channel connects the outer Saltfjorden to the large Skjerstad Fjord between the islands of Straumøya and Knaplundsøya. The Saltstraumen Bridge on Norwegian County Road 17 crosses Saltstraumen. Current Saltstraumen has one of the strongest tidal currents in the world. Up to of seawater forces its way through a long and wide strait every six hours. Vortex, Vortices known as whirlpools or Maelstrom (whirlpool), maelstroms up to in diameter and in depth are formed when the current is at its strongest. At this point, one source claims that the tidal current can reach . Saltstraumen has existed for about two to three thousand years. Before that, the area was different due to post-glacial rebound. The current is created when the tide tries to fill Skjers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tidal Rapid
Tidal race or tidal rapid is a natural occurrence whereby a fast-moving tide passes through a constriction, resulting in the formation of waves, eddies and hazardous currents. The constriction can be a passage where the sides narrow, for example the Gulf of Corryvreckan and the Saltstraumen maelstrom, or an underwater obstruction (a reef or rising seabed), such as is found at the Portland Race in the United Kingdom. In extreme cases, such as Skookumchuck Narrows in British Columbia, through which tides can travel at more than 17 knots (31.484 km/h), very large whirlpools develop, which can be extremely hazardous to navigation.

Terminal Moraine
A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when a glacier retreats from ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
