Nordaust-Svalbard Nature Reserve
Nordaust-Svalbard Nature Reserve () is located in the north-eastern part of the Svalbard archipelago in Norway. The nature reserve covers all of Nordaustlandet, Kong Karls Land, Kvitøya, Sjuøyane, Storøya, Lågøya, Wilhelm Island, Wahlbergøya and a small section of the north-east corner of Spitsbergen. The reserve is , of which is on land and is on water—making it the largest preserved area in Norway (including national parks). It includes the largest glacier in Norway, Austfonna, as well as Vestfonna and parts of Olav V Land. The reserve has been protected since 1 July 1973 and borders in the south to Søraust-Svalbard Nature Reserve. Description Three-quarters of Nordaustlandet is covered by glaciers, the largest being Austfonna at . The landscape has low, rounded hills and plains, created by glaciation during former ice ages. Most of the reserve has little or no vegetation, and the reserve belongs to the polar desert. The nature reserve is used by scientist ...

Hinlopen Strait
The Hinlopen Strait () is the strait between Spitsbergen and Nordaustlandet in Svalbard, Norway. It is long and wide. The strait is difficult to pass because of pack ice. It is believed to have been named after Thijmen Jacobsz Hinlopen. The northern part of the strait is called Nordporten, between Storsteinhalvøya and Mosselhalvøya Mosselhalvøya is a peninsula in Ny-Friesland at Spitsbergen, Svalbard. It is located between Mosselbukta and Sorgfjorden. At the northern part of the peninsular is the coastal plain of Verlegenhukflya, with its northernmost point Verlegenhuken. R .... The southern part, called Sørporten, widens up between Bråsvellbreen and the Bastian Islands.

Meridian Arc
In geodesy and navigation, a meridian arc is the curve (geometry), curve between two points near the Earth's surface having the same longitude. The term may refer either to a arc (geometry), segment of the meridian (geography), meridian, or to its Arc length, length. Both the practical determination of meridian arcs (employing measuring instruments in field campaigns) as well as its theoretical calculation (based on geometry and abstract mathematics) have been pursued for many years. Measurement The purpose of measuring meridian arcs is to determine a figure of the Earth. One or more measurements of meridian arcs can be used to infer the shape of the reference ellipsoid that best approximates the geoid in the region of the measurements. Measurements of meridian arcs at several latitudes along many meridians around the world can be combined in order to approximate a ''geocentric ellipsoid'' intended to fit the entire world. The earliest determinations of the size of a spherical E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andréeneset
Andréeneset is headland at the southwestern point of the island of Kvitøya in the Norwegian Svalbard archipelago in the Arctic Ocean. One of the few ice-free land areas on the island, it is barren and rocky. It is named after engineer and Arctic explorer Salomon August Andrée Salomon August Andrée (18 October 1854 – October 1897), during his lifetime most often known as S. A.

Krossøya
Krossøya is an island at the northwestern side of Nordaustlandet, Svalbard. It is located in the outer part of Murchisonfjorden, separated by Nordre Russøysundet from Søre Russøya, further east, and south of Depotøya. The name Krossøya originates from an old Russian cross, erected at the top of the island.

Bråsvellbreen
Bråsvellbreen () is a glacier in Nordaustlandet, Svalbard. The glacier is a 45 kilometre long stream southwards from the ice dome Sørdomen of Austfonna, debouching into the sea on the south coast. In the late 1930s it was observed that the glacier had exhibited a recent huge surge, forming a ten kilometre long tongue into the sea. This glacier, representing 13% of the total surface of Austfonna, is well known in the Arctic The Arctic (; . ) is the polar regions of Earth, polar region of Earth that surrounds the North Pole, lying within the Arctic Circle.

Polar Desert
Polar deserts are the regions of Earth that fall under an ice cap climate (''EF'' under the Köppen classification). Despite rainfall totals low enough to normally classify as a desert, polar deserts are distinguished from true deserts (' or ' under the Köppen classification) by low annual temperatures and evapotranspiration. Most polar deserts are covered in ice sheets, ice fields, or ice caps, and they are also called ''white deserts''. Polar deserts are one of two polar biomes, the other being Arctic tundra. These biomes are located at the poles of Earth, covering much of the Antarctic in the southern hemisphere, and in the northern hemisphere extending from the Arctic into North America, Europe and Asia. Unlike the tundra that can support plant and animal life in the summer, polar deserts are largely barren environments, comprising permanent, flat layers of ice; due to the scarcity of liquid water, the same is also true of the few ice-free areas. However, there is evidence o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages, and greenhouse periods during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, the term ''ice age'' is defined by the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, the current Holocene epoch is an interglacial period of an ice age. The accumulation of anthropogenic greenhouse gases is projected to delay the next glacial period.
