Raet National Park
Raet National Park ( no, Raet nasjonalpark) is a national park in Arendal, Tvedestrand and Grimstad in Agder, southeastern Norway. It is mostly a marine park, and includes some islands and coastal areas. Raet covers an area of , of which is sea and is land. The park was established on 16 December 2016. Raet Raet National Park is named for the long moraine formed by the retreat of a huge glacier about 12,000 years ago, which dumped an enormous quantity of boulders, pebbles, gravel, sand and clay that it had picked up over the centuries. This quaternary geological formation can be traced all over Scandinavia; in Raet National Park it is partly on land and partly under the sea. Pebble beaches are characteristic in areas where the material is graded by heavy seas, but in more protected areas, the moraine forms fine sandy beaches that are attractive to bathers, as occur at Hove on Tromøya and on the island of Merdø. Further inland there is farmland in many places, but these areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protected Areas Established In 2016
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

National Parks Of Norway
Norway has 47 national parks, of which 40 are on the mainland and 7 on Svalbard. National parks in Norway are stricter than many other countries, and nearly all motorized vehicles are prohibited. The Right to roam applies, thus hiking, skiing and camping throughout the park are permitted, given that consideration to nature is taken. Roads, accommodation and national park centers are located outside the national parks. The parks are under the management oThe Norwegian Environment Agency and the local county governor. Ytre Hvaler is a marine park and all parks in Svalbard also contain marine areas. Sør-Spitsbergen is the largest park, covering an area of , although only is land.

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nidelva (Aust-Agder)

Kelp Forest
Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth.Mann, K.H. 1973. Seaweeds: their productivity and strategy for growth. Science 182: 975-981. Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global Primary production, primary productivity. Kelp forests occur worldwide throughout temperate and polar region, polar coastal oceans. In 2007, kelp forests were also discovered in tropical waters near Ecuador.Graham, M.H., B.P. Kinlan, L.D. Druehl, L.E. Garske, and S. Banks. 2007. Deep-water kelp refugia as potential hotspots of tropical marine diversity and productivity. Proceedings of the National Academy of Sciences 104: 16576-16580.

Glacier
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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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.
