Port Foster
Port Foster is one of the safest harbours in Antarctica, located in Deception Island in the South Shetland Islands. History The harbour was known to sealers as early as 1820, and in its early history was called ''Port Williams'', after Captain William Smith's brig, ''Williams''; or ''Yankee Harbor'', because of the number of American sealers who harboured there. The port, briefly called Yankee Harbour and Port Dunbar, was named Port Foster after Henry Foster, captain of and leader of the first scientific expedition to the island in Jan.-March 1829. The expedition, based in Pendulum Cove, made gravitational and magnetic measurements, produced the first topographic map, made temperature measurements, and made a hydrographic survey. Former names for the port have remained for other features in the same archipelago — Williams Point and Yankee Harbor. Description The centre of Deception Island is a caldera, formed by a gigantic volcanic eruption and later flooded. This has ...

Deception Island Map
Deception or falsehood is an act or statement that misleads, hides the truth, or promotes a belief, concept, or idea that is not true. It is often done for personal gain or advantage. Deception can involve dissimulation, propaganda and sleight of hand as well as distraction, camouflage or concealment. There is also self-deception, as in bad faith. It can also be called, with varying subjective implications, beguilement, deceit, bluff, mystification, ruse, or subterfuge. Deception is a major relational transgression that often leads to feelings of betrayal and distrust between relational partners. Deception violates relational rules and is considered to be a negative violation of expectations. Most people expect friends, relational partners, and even strangers to be truthful most of the time. If people expected most conversations to be untruthful, talking and communicating with others would require distraction and misdirection to acquire reliable information. A significant amount ...

Antarctic Specially Protected Areas
An Antarctic Specially Protected Area (ASPA) is an area on the continent of Antarctica, or on nearby islands, which is protected by scientists and several different international bodies. The protected areas were established in 1961 under the Antarctic Treaty System, which governs all the land and water south of 60 latitude and protects against human development. A permit is required for entry into any ASPA site. The ASPA sites are protected by the governments of Australia, New Zealand, United States, United Kingdom, Chile, France, Argentina, Poland, Russia, Norway, Japan, India, Italy, and Republic of Korea. There are currently 72 sites.

Geography Of Deception Island
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wensleydale Beacon
Wensleydale Beacon () is a hill, 110 m, situated just north of Fumarole Bay, on the west side of Port Foster, Deception Island, in the South Shetland Islands. The hill was charted by a British expedition 1828–31, under Foster. Named by Lieutenant Commander D.N. Penfold, Royal Navy, following his survey of the island in 1948–49, after Wensleydale Wensleydale is the dale or upper valley of the River Ure on the east side of the Pennines, one of the Yorkshire Dales in North Yorkshire, England.

Stancomb Cove
Stancomb Cove () is a cove northeast of Cross Hill in the northwest part of Port Foster, Deception Island, in the South Shetland Islands. The feature was formed as the result of volcanic eruptions on the island An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island ... between December 1967 and August 1970.

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Benthic Zone
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertida ...

Neptune's Bellows
Neptune's Bellows is a channel on the southeast side of Deception Island forming the entrance to Port Foster, in the South Shetland Islands. The name, after the Roman sea god Neptune Neptune is the eighth planet from the Sun and the farthest known planet in the Solar System. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times ..., was appended by American sealers prior to 1822 because of the strong gusts experienced in this narrow channel. Named for "the gusts that blow in and out as if they came from a trumpet or funnell (sic)."

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
