Laurentian Fan
The Laurentian Fan or Laurentian Abyss is an underwater depression off the eastern coast of Canada in the Atlantic Ocean. Not a trench, but more of an "underwater valley", it is estimated to be at most ~19,685 feet (3.7 miles; 6.0 km) in depth. The Laurentian Fan is a product of glaciation and water currents from the Gulf of Saint Lawrence.Information gathered via a phone interview with Dr. Norm Catto of Memorial University - August 15, 2008 It is part of the Laurentian cone region, bound by the Laurentian Channel and the Sohm Abyssal Plain. Towards the end of the 1980s, it was discovered unexpectedly that the fan is the site of hydrothermal vents with their own ecosystems functioning in the absence of sunlight. These supported organisms such as vesicomyid and thyasirid clams, as well as marine gastropods and other epifauna similar to those found in hydrothermal and cold seep environments elsewhere. The approximate coordinates are . The Laurentian Fan plays an important role in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna of Madagascar, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Greek language, Greek equivalent of fauna. ''Fauna'' is also ...

Abyssal Plain
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between and . Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface. They are among the flattest, smoothest, and least explored regions on Earth. Abyssal plains are key geologic elements of oceanic basins (the other elements being an elevated mid-ocean ridge and flanking abyssal hills). The creation of the abyssal plain is the result of the spreading of the seafloor (plate tectonics) and the melting of the lower oceanic crust. Magma rises from above the asthenosphere (a layer of the upper mantle), and as this basaltic material reaches the surface at mid-ocean ridges, it forms new oceanic crust, which is constantly pulled sideways by spreading of the seafloor. Abyssal plains result from the blanketing of an originally uneven surface of oceanic crust by fine-grained sediments, mainly clay and silt. Much ...

Decepticons
The Decepticons are the main antagonists in the fictional continuities of the ''Transformers'' multimedia franchise. They are depicted as a faction of sentient robotic lifeforms led by Megatron, identified by a purple face-like insignia. Capable of transforming into alternate forms, these are often high tech or powerful vehicles; including aircraft, military vehicles, heavy equipment, ground combat vehicles, expensive luxury cars, sports cars and even smaller-than-human-sized objects. In the Japanese version of the franchise, the Decepticons are called Destron or Deathtron ( ja, デストロン ''Desutoron''). The only exception to this naming convention is ''Car Robots'', where the sub-group referred to as "Decepticons" in the '' Robots in Disguise'' adaptation, is known in Japan as the Combatrons (the Japanese name of the G1 subgroup known as the Combaticons). As opposed to the Autobots' Supreme Commander, the Primes, the Decepticons' highest ranking leader is often give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Hunt For Red October
''The Hunt for Red October'' is the debut novel by American author Tom Clancy, first published on October 1, 1984, by the Naval Institute Press. It depicts Soviet submarine captain Marko Ramius as he seemingly goes rogue with his country's cutting-edge ballistic missile submarine ''Red October'', and marks the first appearance of Clancy's most popular fictional character, Jack Ryan, an analyst working for the Central Intelligence Agency, as he must prove his theory that Ramius had intended to defect to the United States. ''The Hunt for Red October'' launched Clancy's successful career as a novelist, especially after then-U.S. President Ronald Reagan remarked that he had enjoyed reading the book. A film adaptation was released on March 2, 1990, and several computer and video games based on the book have been developed. The book was instrumental in bringing the book genre of techno-thriller into the mainstream. Plot summary During the Cold War, Marko Ramius, a Soviet Navy ...

Academia
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Seep
A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. ''Cold'' does not mean that the temperature of the seepage is lower than that of the surrounding sea water. On the contrary, its temperature is often slightly higher. The "cold" is relative to the very warm (at least ) conditions of a hydrothermal vent. Cold seeps constitute a biome supporting several endemic species. Cold seeps develop unique topography over time, where reactions between methane and seawater create carbonate rock formations and reefs. These reactions may also be dependent on bacterial activity. Ikaite, a hydrous calcium carbonate, can be associated with oxidizing methane at cold seeps. Types Types of cold seeps can be distinguished according to the depth, as shallow cold seeps and deep cold seeps. Cold seeps can also be distinguished in detail, as follows: * oil/gas ...

Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Clam
Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; however, razor clams have an elongated parallel-sided shell, suggesting an old-fashioned s ...
