Fenwick Ice Piedmont
The Adare Peninsula (), is a high ice-covered peninsula, long, in the northeast part of Victoria Land, extending south from Cape Adare to Cape Roget. The peninsula was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for Cape Adare. The peninsula is considered the southernmost point of the Borchgrevink Coast, named for Carsten Borchgrevink (1864-1934). Geology The Adare Peninsula consists of overlapping shield volcanoes that have been potassium–argon dated 6 to 13 million years old. Potassium–argon dates of 2.27 million years and perhaps 1.14 million years have also been obtained. The Adare Peninsula shields form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. West coast features Named features on the west coast, which faces Robertson Bay, are (from north to south): Cape Adare . A prominent cape of black basalt which is in visual contrast to the rest of the snow-covered coast, forming the north tip of Adare Peninsula. The cape ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78th parallel south, 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Victoria of the United Kingdom, Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. History Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 Meteorite, meteorites in Antarctica, some of which were found near the Allan Hills in Victoria Land. The meteorites appeared to have undergone little change since they were formed at what scientists believe was the birth of the Solar System. In 1981, Lichen, lichens fo ...

Miocene Shield Volcanoes
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volcanoes Of Victoria Land
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 an ...

Pennell Coast
Pennell Coast is that portion of the coast of Antarctica between Cape Williams and Cape Adare. To the west of Cape Williams lies Oates Coast, and to the east and south of Cape Adare lies Borchgrevink Coast. Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Lieutenant Harry Pennell, Royal Navy, commander of the Terra Nova, the expedition ship of the British Antarctic Expedition, 1910–13. Pennell engaged in oceanographic work in the Ross Sea during this period. In February 1911 he sailed along this coast in exploration and an endeavor to land the Northern Party led by Lieutenant Victor Campbell. The name is also used more loosely to refer to both the coast itself and the hinterland extending south to the watershed of the Southern Cross Mountains to the southeast and the Usarp Mountains to the west. Major features of the coast include the 250-kilometer long Rennick Glacier (one of Antarctica's largest glaciers), the Anare Mountains, and the norther ...

Peninsulas Of Victoria Land
A peninsula is a landform that extends from a mainland and is only connected to land on one side. Peninsulas exist on each continent. The largest peninsula in the world is the Arabian Peninsula. Etymology The word ''peninsula'' derives , . The word entered English in the 16th century. Definitions A peninsula is generally defined as a piece of land surrounded on most sides by water. A peninsula may be bordered by more than one body of water, and the body of water does not have to be an ocean or a sea. A piece of land on a very tight river bend or one between two rivers is sometimes said to form a peninsula, for example in the New Barbadoes Neck in New Jersey, United States. A peninsula may be connected to the mainland via an isthmus, for example, in the Isthmus of Corinth which connects to the Peloponnese peninsula. Formation and types Peninsulas can be formed from continental drift, glacial erosion, glacial meltwater, glacial deposition, marine sediment, marine transg ...

Global Volcanism Program
The Smithsonian Institution's Global Volcanism Program (GVP) documents Earth's volcanoes and their eruptive history during the Quaternary Period of Earth's geologic history, with particular emphasis on volcanic activity during the Holocene Epoch (the last 11,700 years). The mission of the GVP is to document, understand, and disseminate information about global volcanic activity. Global Volcanism Program Database The GVP gathers information and reports on current eruptions from around the world, and maintains a database repository on active volcanoes, their eruptions and their eruption histories. In this way, a global context for the planet's active volcanism is presented. Smithsonian reporting on current volcanic activity dates back to 1968, with the Center for Short-Lived Phenomena (CSLP). The GVP is housed in the Department of Mineral Sciences, part of the National Museum of Natural History, on the National Mall in Washington, D.C. During the early stages of an eruption, ...
