Watermill Cove
Watermill Cove is on the north–east coast of St Mary's, Isles of Scilly. It is a historic anchorage, still used today by passing yachts and other small vessels. At Tregear's Porth, there are the remains of an old quay, with the slipway still in use for small craft. The cove is within an Area of Outstanding Beauty, is a Geological Conservation Review site and was designated a Site of Special Scientific Interest (SSSI) in 1996. The site is notified for a succession of Quaternary exposures in the cliff and from sea level to the top of the cliff (oldest to youngest) the succession shows: * head deposits *organic silts and sands *head deposits of the Late Devensian with microscopic remains of plants and pollen and dated to c. 30,000 years before present. The remains indicate an Arctic tundra climate *raised beach deposits, a storm beach of the Late Ipswichian interglacial An interglacial period (or alternatively interglacial, interglaciation) is a geological interval of warmer ...

Watermill Cove - Geograph
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further divided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential trait about their location: tide mills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...

Natural England
Natural England is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. It is responsible for ensuring that England's natural environment, including its land, flora and fauna, freshwater and marine environments, geology and soils, are protected and improved. It also has a responsibility to help people enjoy, understand and access the natural environment. Natural England focuses its activities and resources on four strategic outcomes: * a healthy natural environment * enjoyment of the natural environment * sustainable use of the natural environment * a secure environmental future Roles and responsibilities As a non-departmental public body (NDPB), Natural England is independent of government. However, the Secretary of State for Environment, Food & Rural Affairs has the legal power to issue guidance to Natural England on various matters, a constraint that was not placed on its predecessor NDPBs. Its powers inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interglacial
An interglacial period (or alternatively interglacial, interglaciation) is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age. The current Holocene interglacial began at the end of the Pleistocene, about 11,700 years ago. Pleistocene During the 2.5 million years of the Pleistocene, numerous glacials, or significant advances of continental ice sheets, in North America and Europe, occurred at intervals of approximately 40,000 to 100,000 years. The long glacial periods were separated by more temperate and shorter interglacials. During interglacials, such as the present one, the climate warms and the tundra recedes polewards following the ice sheets. Forests return to areas that once supported tundra vegetation. Interglacials are identified on land or in shallow epicontinental seas by their paleontology. Floral and faunal remains of species pointing to temperate climate and indicating a s ...

Ipswichian
The Eemian (also called the last interglacial, Sangamonian Stage, Ipswichian, Mikulin, Kaydaky, penultimate,NOAA - Penultimate Interglacial Period http://www.ncdc.noaa.gov/global-warming/penultimate-interglacial-period Valdivia or Riss-Würm) was the interglacial period which began about 130,000 years ago at the end of the Penultimate Glacial Period and ended about 115,000 years ago at the beginning of the Last Glacial Period. It corresponds to Marine Isotope Stage 5e. Although sometimes referred to as the "last interglacial" (in the "most recent previous" sense of "last"), it was the second-to-latest interglacial period of the current Ice Age, the most recent being the Holocene which extends to the present day (having followed the last glacial period). The prevailing Eemian climate was, on average, around 1 to 2 degrees Celsius (1.8 to 3.6 Fahrenheit) warmer than that of the Holocene. During the Eemian, the proportion of in the atmosphere was about 280 parts per million. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Beach
A storm beach is a beach affected by particularly fierce wind wave, waves, usually with a very long fetch (geography), fetch. The resultant landform is often a very steep beach (up to 45°) composed of rounded Cobble (geology), cobbles, shingle beach, shingle and occasionally sand. The stones usually have an obvious Grade (slope), grading of pebbles, from large to small, with the larger diameter stones typically arrayed at the highest beach elevations. It may also contain many small parts of shipwrecked boats. Examples A noted textbook example is the long Chesil Beach in Dorset, one of three major shingle structures in Britain. It also connects the Isle of Portland to the mainland at Abbotsbury, west of the resort of Weymouth, Dorset, Weymouth. Other examples appear in the Shetland Islands, Shetland and Orkney Islands, as well as the Scotland, Scottish mainland at Caithness. The beaches of Lakshdweep Islands are also storm beaches.

Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Mary's, Isles Of Scilly
St Mary's ( kw, Ennor, meaning ''The Mainland'') is the largest and most populous island of the Isles of Scilly, an archipelago off the southwest coast of Cornwall in England. Description St Mary's has an area of — 40 percent of the total land area of the Isles of Scilly — this includes four small tidal islands which connect with St Mary's at low tide: Toll's Island, Taylor's Island, Newford Island and the island at Innisidgen. With a population of 1,723 (out of a total population for Scilly of 2,203) St Mary's is relatively densely populated, with twice the average population density of the Isles of Scilly as a whole. The majority of St Mary's residents live in the western half of the island, with Hugh Town alone having a population of 1,097. The main settlement, Hugh Town ''( Cornish: Tre Huw)'', was sold to the inhabitants by the Crown in 1949 (it had belonged to the Duchy of Cornwall — which still owns much of the rest of the island). Other settlements on the island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
