Qinngua Valley
Qinngua Valley, also called Qinnquadalen, Kanginsap Qinngua and Paradisdalen, is a valley in Greenland, about from the nearest settlement of Tasiusaq, Kujalleq. The valley has the only natural forest in Greenland and is about long, running roughly north to south and terminating at Tasersuag Lake. The lake drains into Tasermiut Fjord. Mountains rise as much as on either side of the narrow valley. The valley is situated about from the sea and protected from the cold winds coming off the interior glaciers of Greenland. In total, over 300 species of plants grow in the valley. The forest in Qinngua Valley is a thicket consisting mainly of downy birch (''Betula pubescens'') and gray-leaf willow (''Salix glauca''), growing up to tall. Growing sometimes to tree height is the Greenland mountain ash ('' Sorbus groenlandica''), which is usually a shrub. Green alder ('' Alnus crispa'') is also found in the valley. It is possible that other forests of this type once existed in Green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Tasiusaq, Kujalleq
Tasiusaq is a settlement in the Kujalleq municipality in southern Greenland, founded in 1933. It is located at the Tasermiut Fjord ( da, Ketils Fjord), east of Nanortalik. Its population was 53 in 2020. In the Greenlandic language, the name of the settlement means "like a lake", referring to the lake-looking bay it situated on. The inhabitants call it "Tasiisaq", which is the local dialect. There are several sheep farms in the wider Tasiusaq area; the farms of ''Nalasut'' with 10 inhabitants, ''Saputit'' with 3 inhabitants, and ''Nuugaarsuk'' with four inhabitants. Until January 2009 the settlement belonged to the Nanortalik municipality. On 1 January 2009 the settlement became part of the Kujalleq municipality, when the Narsaq, Qaqortoq, and Nanortalik municipalities ceased to exist as administrative entities. Infrastructure and transportation The settlement has a local school, a church, a general store, and a general repairs workshop maintained by the Kujalleq municipality. ...

Tasermiut Fjord
Tasermiut Fjord is a 70-kilometre-long fjord in southwestern Greenland. Administratively it is part of the Kujalleq municipality. Nanortalik Island is located near the mouth of the fjord. Tasermiut Fjord has some of the very few growths of dwarf trees in Greenland, notably in Qinngua Valley and Tiningnertoq valley. Geography The fjord is oriented in a roughly NE/SW direction, to the southwest the fjord opens into the Labrador Sea of the North Atlantic Ocean. It separates two long mountainous peninsulas, the 1,590 m high Napasorsuaq peak rising in the peninsula to the west of the fjord. To the east rise the 1,858 m high Ulamertorsuaq, the 2,045 m high Nalumasortoq and the 2,010 m high Ketil. The glacier at the inland end of this fjord has been undergoing a well documented recession in recent history. A similar retreat of the glacier at the fjord's head has been documented in the Sermeq Glacier in neighbouring Southern Sermilik Fjord as well. Tourism This fjord attracts ...

Glaciers
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betula Pubescens
''Betula pubescens'' (syn. ''Betula alba''), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch (''B. pendula''), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch (''B. nana''). Six varieties are recognised and it hybridises with the silver and dwarf birches. A number of cultivars have been developed but many are no longer in cultivation. The larva of the autumnal moth (''Epirrita autumnata'') feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease. The tree is a pioneer species ...

Salix Glauca
''Salix glauca'' is a species of flowering plant in the willow family known by the common names gray willow, grayleaf willow, white willow, and glaucous willow. It is native to North America, where it occurs throughout much of Alaska, northern and western Canada, and the contiguous United States south through the Rocky Mountains to northern New Mexico.Uchytil, Ronald J. 1992''Salix glauca''.In: Fire Effects Information System, nline U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. It can also be found in Greenland, northwestern Europe, and Siberia. Description This willow is usually a shrub growing up to tall, but in appropriate habitat it becomes a tree up to tall. The smooth gray bark becomes furrowed with age. The species is dioecious, with male and female reproductive parts occurring on separate individuals. This species has secondary sexual dimorphism, with male and female individuals different in function or mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorbus Groenlandica
''Sorbus groenlandica'', the Greenland mountain-ash, is a species of ''Sorbus'' found in Greenland and northeastern North America. A shrub, it cannot be found north of 62°15′N, which confines it the southern tip of Greenland, generally deeper up the western fjords, such as the Qinngua Valley. It can also be found in eastern Canada and the US states of New Hampshire and Maine Maine () is a state in the New England and Northeastern regions of the United States. It borders New Hampshire to the west, the Gulf of Maine to the southeast, and the Canadian provinces of New Brunswick and Quebec to the northeast and ..., but is very rare throughout its range.

Alnus Crispa
''Alnus alnobetula'' is a common tree widespread across much of Europe, Asia, and North America. Many sources refer to it as ''Alnus viridis'', the green alder, but botanically this is considered an illegitimate name synonymous with ''Alnus alnobetula'' subsp. ''fruticosa''. Description It is a large shrub or small tree tall with smooth grey bark even in old age. The leaves are shiny green with light green undersurfaces, ovoid, long and 2–6 cm broad. The flowers are catkins, appearing late in spring after the leaves emerge (unlike other alders which flower before leafing out); the male catkins are pendulous, 4–8 cm long, the female catkins 1 cm long and 0.7 cm broad when mature in late autumn, in clusters of 3–10 on a branched stem. The seeds are small, long, light brown with a narrow encircling wing. The roots of ''Alnus viridis subsp. sinuata'' have nitrogen-fixing nodules. A study in Alaska showed that Sitka alder seedlings were able to invade coa ... [...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 ...

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 ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
