Hydrothermal Vents And Seamounts Of The Azores
The hydrothermal vents and seamounts of the Azores (') are a series of Atlantic Ocean, Atlantic seamounts and hydrothermal vents that are part of the Mid-Atlantic Ridge system, giving rise to the archipelago and bathymetric region of the Azores. These geological structures, formed from masses of basalt (typical of mid-ocean regions), are of a geomorphological interest due to their rich deposits of ore. In addition it fosters a rich ecosystem of diverse subaquatic plant and animal life. There are food chains within this environment, for example, that are purely chemosynthesis, chemosynthetic, and do not need sunlight for photosynthesis. Geography The Azores consists of an extensive marine and terrestrial system of hundreds of active submarine mounts and volcanoes that extend from the Mid-Atlantic Ridge. The islands of the Azores are the visible representation of the complex ridge of undersea mountains that extend from Iceland to Antarctic. Below the waters of the Azores are unders ...

Volcano
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 str ...

Rimicaris Exoculata
''Rimicaris exoculata'', commonly known as the 'blind shrimp', is a species of shrimp. It thrives on active hydrothermal edifices at deep-sea vents of the Mid-Atlantic Ridge. This species belongs to the Alvinocarididae family of shrimp, named after the DSV Alvin, the vessel that collected the original samples described by M. L. Christoffersen in 1986. The genus name ''Rimicaris'' is composed of ''rima'' (Latin for "rift" or "fissure", referring to the Mid-Atlantic Ridge) + ''karis'' ("shrimp" in Greek), while the species epithet benign is Latin for "rendered eyeless", referring to the highly modified, non-image-forming eyes. Description ''Rimicaris exoculata'' typically measures between in length and weighs an average of . During the moult cycle of their exoskeleton, this species transitions from white to translucent due to mineral deposits in the branchial chamber. Both sides of their body are covered in many long bacteriophore setae, and they possess an enlarged cephaloth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrimp
A shrimp (: shrimp (American English, US) or shrimps (British English, UK)) is a crustacean with an elongated body and a primarily Aquatic locomotion, swimming mode of locomotion – typically Decapods belonging to the Caridea or Dendrobranchiata, although some Shrimp#Non-decapods, crustaceans outside of this order are also referred to as "shrimp". Any small crustacean may also be referred to as "shrimp", regardless of resemblance. More narrow definitions may be restricted to Caridea, to smaller species of either of the aforementioned groups, or only the Marine life, marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (Abdomen#Arthropoda, abdomens), long whiskers (Antenna (biology), antennae), and slender, Biramous, biramous legs. They swim forward by paddling the swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks wit ...

Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and Freshwater bivalve, freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong Byssus, byssal threads ("beard") to a firm substrate. A few species (in the genus ''Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exclusive Economic Zone
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine natural resource, resources, including energy production from water and wind. It stretches from the outer limit of the territorial sea (22.224 kilometres or 12 nautical miles from the baseline) out 370.4 kilometres (or 200 nautical miles) from the coast of the state in question. It is also referred to as a maritime continental margin and, in colloquial usage, may include the continental shelf. The term does not include either the Territorial waters#Territorial sea, territorial sea or the continental shelf beyond the 200 nautical mile limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's righ ...

São Miguel Island
São Miguel Island (; ), nicknamed "The Green Island" (), is the largest and most populous island in the Portugal, Portuguese archipelago of the Azores. The island covers and has around 140,000 inhabitants, with 45,000 people residing in Ponta Delgada, the archipelago's largest city. History In 1427, São Miguel became the second of the islands discovered by Gonçalo Velho Cabral to be settled by colonists from continental Portugal. This date is uncertain, as it is believed that the island was discovered between 1426 and 1437 and inscribed in portolans from the middle of the 15th century. Its discovery was later recorded by Priesthood (Catholic Church), Father Gaspar Frutuoso in the seminal history of the Azores, ''Saudades da Terra'', as he began: "This island of São Miguel where...we are, is mountainous and covered in ravines, and it was, when we discovered it, covered in trees...due to its humidity, with its water showers and ravines warm with sun..." It was sometime afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dom João De Castro Bank
Dom João de Castro Bank () is a large submarine volcano located in the central north Atlantic Ocean, between the islands of São Miguel and Terceira in the archipelago of the Azores. History The first historical reference correlated with the submarine volcanoes between São Miguel and Terceira occurred after two ships of the French corsair Henry Tourin sank in the spring of 1718. The last major eruption associated with this region occurred on 31 December 1720.Sérgio Paulo Ávila (1997), p.1 Beginning as a submarine eruption, it eventually built into a Surtseyan eruption that resulted in the formation of a circular island long and in altitude. Smoke and steam released by the eruption was visible from the islands of São Miguel and Terceira. The eruption also caused multiple small earthquakes felt on those islands. Designated the ''Ilha Nova'' (New Island), it remained above sea-level for only two years, reaching a height of and diameter of . Marine erosion and ocean swells ...
