Edmonds Underwater Park
Edmonds Underwater Park (EUP) is a local classic scuba diving site in the northern Seattle, Washington suburb of Edmonds immediately north of the Edmonds Washington State Ferry terminal on the Edmonds-Kingston route. EUP is relatively shallow with a maximum depth of about 45 feet. There is a grid network of anchored ropes that lead to a variety of submerged features. The park is built and maintained by a group of volunteers that meet every Saturday and Sunday at 9 am. Attractions & features There are several submerged shipwrecks including the large tugboat Triumph. The site is famous for very large ling cod, numerous large cabezon, occasional octopus, many surf perch and rockfish, and a lot of invertebrates. Gray whales have been spotted by divers at this site. Entrance is via moderate surface swims. There is a restroom with diver dressing areas and an outdoor shower that is functional when the weather is above freezing. Just north of the ferry terminal is a 300-foot (91.4 m) ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Octopus
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Restaurant
A restaurant is a business that prepares and serves food and drinks to customers. Meals are generally served and eaten on the premises, but many restaurants also offer take-out and food delivery services. Restaurants vary greatly in appearance and offerings, including a wide variety of cuisines and service models ranging from inexpensive fast-food restaurants and cafeterias to mid-priced family restaurants, to high-priced luxury establishments. Etymology The word derives from early 19th century from French word 'provide food for', literally 'restore to a former state' and, being the present participle of the verb, The term ''restaurant'' may have been used in 1507 as a "restorative beverage", and in correspondence in 1521 to mean 'that which restores the strength, a fortifying food or remedy'. History A public eating establishment similar to a restaurant is mentioned in a 512 BC record from Ancient Egypt. It served only one dish, a plate of cereal, wild fowl, and o ...

Ferry
A ferry is a ship, watercraft or amphibious vehicle used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, and many carry vehicles. History In ancient times The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freezing
Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures. For example, agar displays a hysteresis in its melting point and freezing point. It melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F). Crystallization Most liquids freeze by crystallization, formation of crystalline solid from the uniform liquid. This is a first-order thermodynamic phase transition, which means that as long as solid and liquid coexist, the temperature of the whole system remains very nearly equal to the melting point due to the slow re ...

Weather
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream.

Gray Whale
The gray whale (''Eschrichtius robustus''), also known as the grey whale,Britannica Micro.: v. IV, p. 693. gray back whale, Pacific gray whale, Korean gray whale, or California gray whale, is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of , a weight of up to and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age. The common name of the whale comes from the gray patches and white mottling on its dark skin. Gray whales were once called devil fish because of their fighting behavior when hunted. The gray whale is the sole living species in the genus ''Eschrichtius''. It was formerly thought to be the sole living genus in the family (biology), family Eschrichtiidae, but more recent evidence classifies members of that family in the family Rorqual, Balaenopteridae. This mammal is descended from filter-feeding whales that appeared during the Neogene. The gray whale is distributed in an eastern ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Sebastinae
Sebastinae is a subfamily of marine fish belonging to the family Scorpaenidae in the order Scorpaeniformes. Their common names include rockfishes, rock perches, ocean perches, sea perches, thornyheads, scorpionfishes, sea ruffes and rockcods. Despite the latter name, they are not closely related to the cods in the genus ''Gadus'', nor the rock cod, ''Lotella rhacina''. Taxonomy Sebastinae, or Sebastidae, was first formally recognised as a grouping in 1873 by the German naturalist Johann Jakob Kaup. Some authorities recognise this family as distinct from Scorpaenidae. FishBase, a finfish database generated by a consortium of academic institutions, does, but the United States Federal government's Integrated Taxonomic Information System and the 5th Edition of ''Fishes of the World'' do not, FotW classify it as a subfamily of the Scorpaenidae. Tribes and genera Sebastinae is divided into two tribes and seven genera: * Tribe Sebastini Kaup, 1873 ** ''Helicolenus'' Goode & Bean, 1 ...

Perch
Perch is a common name for fish of the genus ''Perca'', freshwater gamefish belonging to the family Percidae. The perch, of which three species occur in different geographical areas, lend their name to a large order of vertebrates: the Perciformes, from the el, πέρκη (), simply meaning perch, and the Latin ''forma'' meaning shape. Many species of freshwater gamefish more or less resemble perch, but belong to different genera. In fact, the exclusively saltwater-dwelling red drum is often referred to as a red perch, though by definition perch are freshwater fish. Though many fish are referred to as perch as a common name, to be considered a true perch, the fish must be of the family Percidae. The type species for this genus is the European perch, ''P. fluviatilis''. Species Most authorities recognize three species within the perch genus: * The European perch (''P. fluviatilis'') is primarily found in Europe, but a few can also be found in South Africa, and even as far ea ...

Cabezon (fish)
The cabezon (''Scorpaenichthys marmoratus'') is a large species of sculpin native to the Pacific coast of North America. Although the genus name translates literally as "scorpion fish", true scorpionfish (such as lionfish) belong to the related family Scorpaenidae. The cabezon is the only known member of its genus. Taxonomy The cabezon was first formally described as ''Hemitripterus marmoratus'' in 1854 by the American physician and ichthyologist William Orville Ayres with its type locality given as California. Both Ayres and the French biologist Charles Frédéric Girard published the specific name ''marmoratus'' for this taxon in 1854, Ayres published his name on 8 September in ''The Pacific'', a San Francisco based journal in which the California Academy of Sciences published its meeting repotrs, and the name was published once mor on 22 September in the ''Proceedings of the California Academy of Sciences''. Girard's name was deemed to have been published on 6 October and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
