Sigguup Nunaa
Nunavik Peninsula (, ) is a large peninsula in northwestern Greenland. It separates two cultural and geographical regions of northwestern Greenland: Uummannaq Fjord region in the southeast, and Upernavik Archipelago in the north. Geography The peninsula extends to the south-west from mainland Greenland at () north of the Uummannaq Fjord system. The waters around the peninsula are Karrat Fjord in the east, Nordost Bay in the south and Baffin Bay in the west. The Ukkusissat Fjord carves deeply into the northeast of the peninsula, running south to north-east-north around the eastern part of the peninsula covered with the Sermikavasak glacier. Inner fjords Several fjords cut deep into the peninsula. Running from the western shore inland to then turn north, Sullua (4x50km) is the main waterway, cutting the peninsula into two parts, northwestern being the smaller. Parallel Umiiviup Kangerlua (4x8km) and Kangiusap Imaa (3x7km) fjord bays cut into the southeastern shore. Settle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baffin Bay
Baffin Bay (Inuktitut: ''Saknirutiak Imanga''; ; ; ), located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the Atlantic Ocean, North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the Arctic ice pack, ice cover and high density of Sea ice, floating ice and icebergs in the open areas. However, a polynya of about , known as the North Water Polynya, North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region. Extent The International Hydrographic Organization defines the limits of Baffin Bay as follows: History The area of the bay has been inhabited since BC. Around AD 1200, the initial Dorset culture ...

Upernavik
Kanunarinaqiniiaaq (known as Upernavik) is a small town in the Avannaata municipality in northwestern Greenland, located on a small island of the same name. With 1,064 inhabitants as of 2024, it is the twelfth-largest town in Greenland. It contains the Upernavik Museum. It is known as Upernavik. History The town was founded as Upernavik in 1772. From the former name of its island, it was sometimes known as Women's Island; its name was also sometimes Anglicized to "Uppernavik". In 1824, the Kingittorsuaq Runestone was found outside the town. It bears runic characters left by Norsemen, probably from the late 13th century. The runic characters list the names of three Norsemen and mention the construction of a rock cairn nearby. This is the furthest north that any Norse artifacts have been found, other than those small artifacts that could have been carried north by Inuit traders, and marks the northern known limit of Viking exploration. Sailors searching for lost polar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Volcanic
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching a ...

Uummannaq
Uummannaq is a town on Uummannaq Island in the Avannaata municipality, in central-western Greenland. With 1,407 inhabitants in 2020, it is the eighth-largest town in Greenland, and is home to the country's most northerly ferry terminal. Founded in 1763 as Omenak, the town is a hunting and fishing base, with a canning factory and a marble quarry. In 1932, the Universal Greenland-Filmexpedition with director Arnold Fanck released the film '' S.O.S. Eisberg'' near Uummannaq. Geography Uummannaq is located 590 kilometres north of the Arctic Circle on Uummannaq Island, located in the south-central arm of the Uummannaq Fjord. ''Uummannaq'' is also the general name given to the series of inlets north of the promontory at Niaqornat on the Nuussuaq Peninsula. The island is also home to Uummannaq Mountain, rising very sharply to the height of 1170 m. Climbing it requires technical skills.

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the North magnetic pole, Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipode (geography), antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though ...

Paleocene
The Paleocene ( ), or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact (Chicxulub impact) and possibly volcanism (Deccan Traps), marked the beginning of the Paleocene and killed off 75% of species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...
