Doggersbank
Dogger Bank (Dutch language, Dutch: ''Doggersbank'', German language, German: ''Doggerbank'', Danish language, Danish: ''Doggerbanke'') is a large shoal, sandbank in a shallow area of the North Sea about off the east coast of England. During the last ice age the bank was part of a large landmass connecting mainland Europe and the British Isles, now known as Doggerland. It has long been known by fishermen to be a productive fishing bank; it was named after the ''Dogger (boat), doggers'', medieval Netherlands, Dutch fishing boats especially used for catching cod. At the beginning of the 21st century the area was identified as a potential site for a UK round 3 wind farm, being developed as Dogger Bank Wind Farm. Name The name Dogger Bank was first recorded in the mid-17th century. It is probably derived from the word "dogger (boat), dogger" used for a two-masted boat of the type that trawled for fish in the area in medieval times. The area has similar names in Dutch language, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cleaver Bank
The Cleaver Bank (Dutch: ''Klaverbank)'' is a sandbank in the North Sea about off the west coast of the Netherlands and south of the Dogger Bank. The size of the bank is about 1235 km2. The bank is 30-40 metres below sea level. The Cleaver Bank is an open-sea reef in the terms of the European Habitats directive and has been registered with the European Union as a Natura 2000 site. The bank originated as a terminal moraine of a glacier during one of the Ice Ages. The surface of the bank partly consists of gravel and larger cobbles. Due to the relatively great depth of the Cleaver Bank, the soil is only seldom, in very heavy weather, moved by wave action. Because the gravel is relatively poor in silt and the transparency is great, there is enough light to allow for the growth of calcareous red algae. The benthic fauna on the bank contains species that live on a hard substrate, such as sea anemones and polyps. Rare species living on Cleaver Bank are Thracia convexa and the Rayed ...

Hypocenter
In seismology, a hypocenter or hypocentre () is the point of origin of an earthquake or a subsurface nuclear explosion. A synonym is the focus of an earthquake. Earthquakes An earthquake's hypocenter is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture.''The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus.'' This occurs directly beneath the epicenter, at a distance known as the ''hypocentral depth'' or ''focal depth''. The focal depth can be calculated from measurements based on seismic wave phenomena. As with all wave phenomena in physics, there is uncertainty in such measurements that grows with the wavelength so the focal depth of the source of these long-wavelength (low frequency) waves is difficult to determine exactly. Very strong earthquakes radiate a large fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richter Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

1931 Dogger Bank Earthquake
The Dogger Bank earthquake of 1931 was the strongest earthquake recorded in the United Kingdom since measurements began. It had a magnitude of 6.1 on the Richter magnitude scale, and it caused a shaking intensity of VI (''Strong'') to VII (''Very strong'') on the Mercalli intensity scale. The location of the earthquake in the North Sea meant that damage was significantly less than it would have been had the epicentre been on the British mainland. Earthquake The tremor began at around 1:30 am on 7 June 1931 with its epicentre located at the Dogger Bank, off the Yorkshire coast in the North Sea. The effects were felt throughout Great Britain as well as in Belgium and France. The earthquake resulted in damage at locations throughout eastern England. The coastal town of Filey in Yorkshire was worst hit, with the spire of a church being twisted by the tremor. Chimneys collapsed in Hull, Beverley and Bridlington, and Flamborough Head suffered crumbling of parts of its cliffs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeolithic
The Paleolithic or Palaeolithic (), also called the Old Stone Age (from Greek: παλαιός ''palaios'', "old" and λίθος ''lithos'', "stone"), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 cal BP. The Paleolithic Age in Europe preceded the Mesolithic Age, although the date of the transition varies geographically by several thousand years. During the Paleolithic Age, hominins grouped together in small societies such as bands and subsisted by gathering plants, fishing, and hunting or scavenging wild animals. The Paleolithic Age is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, includ ...

Rhinoceros
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths; they rely instead on their lips to pl ...

Mammoth
A mammoth is any species of the extinct elephantid genus ''Mammuthus'', one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors. Mammoths are more closely related to living Asian elephants than African elephants. The oldest representative of ''Mammuthus'', the South African mammoth (''M. subplanifrons''), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Trawler
A fishing trawler is a commercial fishing vessel designed to operate Trawling, fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom. History During the 17th century, the British developed the Dogge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
