Navarana Fjord
Navarana Fjord is a fjord in Peary Land, far northern Greenland. It is named after an Inuit woman. In 1984 important zinc and barium deposits were discovered in the Navarana Fjord. Australian Ironbark Zinc corporation was granted an exploration licence in 2007. History This fjord was mapped by Danish Arctic explorer Eigil Knuth during the Danish Peary Land Expedition of 1947–1950. It was named after Navarana Mequpaluk (died 1921), the wife of Arctic explorer Peter Freuchen (1886–1957). Navarana had died at Upernavik in 1921 just before joining the Fifth Thule Expedition with her husband. Her death came at the time of the influenza epidemic that ravaged indigenous populations in Greenland in the early 1920s.Janice Cavell & Jeff Noakes, ''Acts of Occupation: Canada and Arctic Sovereignty, 1918–25''; p. 140 Geography Navarana Fjord is located in the northeastern part of Freuchen Land, western Peary Land.

Freuchen Land
Freuchen Land is a peninsula in far northwestern Greenland. It is a part of the Northeast Greenland National Park. History Freuchen Land was named after Arctic explorer Peter Freuchen (1886–1957), who took part in the 1906–1908 Denmark expedition and later in Knud Rasmussen's Thule expeditions. Geography Freuchen Land is located to the northeast of Nares Land, south of Sverdrup Island, and west of Nansen Land and the Hans Tausen Ice Cap. Its westernmost headland is Cape Wegener. The peninsula is bounded to the west by the Nordenskiöld Fjord and to the east by the J.P. Koch Fjord. Navarana Fjord, a branch of J.P. Koch Fjord, cuts deeply southwards into the peninsula, nearly dividing it in two. This fjord was named after Peter Freuchen's Inuit wife, Navarana Mequpaluk (died 1921) To the southeast lie the Henson Gletscher and the Expedition Glacier which have their terminus at the J.P. Koch Fjord. To the south the peninsula is attached to the mainland and its ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peary Land
Peary Land is a peninsula in northern Greenland, extending into the Arctic Ocean. It reaches from Victoria Fjord in the west to Independence Fjord in the south and southeast, and to the Arctic Ocean in the north, with Cape Morris Jesup, the northernmost point of Greenland's mainland, and Cape Bridgman in the northeast. History Ancient settlements Peary Land was historically inhabited by three separate cultures, during which times the climate was milder than presently: *Independence I culture, Paleo-Eskimo (around 2000 BC, oldest remains dating from 2400 BC) *Independence II culture, Paleo-Eskimo (800 BC to 200 BC) *Thule culture (ancestral to the modern Inuit, around AD 1300) Peary's explorations The area is named after Robert E. Peary, who first explored it during his expedition of 1891 to 1892. Originally, Peary Land was believed to be an island, separated from the main island by the so-called Peary Channel, an assumed connection between Nordenskiöld Fjord and Independe ...

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'', ...

Sponge Spicule
Spicules are structural elements found in most sponges. The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. Sponge spicules are made of calcium carbonate or silica. Large spicules visible to the naked eye are referred to as megascleres, while smaller, microscopic ones are termed microscleres. The composition, size, and shape of spicules are major characters in sponge systematics and taxonomy. Overview Sponges are a species-rich clade of the earliest-diverging (most basal) animals. They are distributed globally, with diverse ecologies and functions, and a record spanning at least the entire Phanerozoic. Most sponges produce skeletons formed by spicules, structural elements that develop in a wide variety of sizes and three dimensional shapes. Among the four sub-clades of Porifera, three (Demospongiae, Hexactinellida, and Homoscleromorpha) produce skeletons of amorphous silica and on ...

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Nyeboe Land
Nyeboe Land ( da, Nyeboes Land) is a peninsula in far northwestern Greenland. It is a part of the Northeast Greenland National Park. History Nyeboe Land was named after engineer Marius Nyeboe (1867–1946), chairman of the committee of Knud Rasmussen's Fifth Thule Expedition. Geography Nyeboe Land is located to the northeast of Hall Land in the west, and southwest of Hendrik Island and west of Warming Land and the Steensby Glacier in the east. It is bounded to the north by the Lincoln Sea and to the east by Saint George Fjord. Newman Fjord (Newman Bay) marks the western limit of Nyeboe Land. To the south and southeast the peninsula is attached to the mainland and its ice cap. The Dreyer Firn is located in the southwest, near the Saint George Fjord's shore. There are three small bays in the northern shore, Repulse Harbour, Hand Bay and Frankfield Bay, from west to east. Nyeboe Land is largely unglaciated and mountainous.GoogleEarth high Punch Mountain, the highest eleva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized.

Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
