Siletz Reef (Lincoln County, Oregon)
The Siletz Reef is a large and shallow reef, just offshore the central coast of Oregon. It runs about mile offshore from a southern boundary off Depoe Bay, though some references have it going as far south as Cape Perpetua to a northern boundary off Lincoln City, Oregon, though a northern boundary of Cascade Head is in some references. The reef is rocky and is believed to comprise a few fairly large continuous rock structures and a wide expanse of smaller structures. It has been written as about offshore from Lincoln City, Oregon. The reef is often fished, and many whale watching and sightseeing charter vessels operate near the reef. Common species in the reef Black rockfish comprise up 23% of the total fish. Blue rockfish, kelp greenling and juvenile rockfish were next at 14%. Lingcod and Canary rockfish and each made up roughly 9%, with yellowtail rockfish at 3%. Species occurring only rarely or less than 3% of the total were China rockfish, copper rockfish, yellow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic component, abiotic processes—deposition (geology), deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic component, biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yelloweye Rockfish
The yelloweye rockfish (''Sebastes ruberrimus'') is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. and one of the biggest members of the genus '' Sebastes''. Its name derives from its coloration. It is also locally known as "red snapper", not to be confused with the warm-water Atlantic species '' Lutjanus campechanus'' that formally carries the name red snapper. The yelloweye is one of the world's longest-lived fish species, and is cited to live to a maximum of 114 to 120 years of age. As they grow older, they change in color, from reddish in youth, to bright orange in adulthood, to pale yellow in old age. Yelloweye live in rocky areas and feed on small fish and other rockfish. They reside in the East Pacific and range from Baja California to Dutch Harbor in Alaska. Yelloweye rockfish are prized for their meat, and were declared overfished in 2002, at which time a survey determined that their population, ...

Ocean Bank
An ocean bank, sometimes referred to as a fishing bank or simply bank, is a part of the seabed that is shallow compared to its surrounding area, such as a shoal or the top of an underwater hill. Somewhat like continental slopes, ocean bank slopes can upwell as tidal and other flows intercept them, sometimes resulting in nutrient-rich currents. Because of this, some large banks, such as Dogger Bank and the Grand Banks of Newfoundland, are among the richest fishing grounds in the world. There are some banks that were reported in the 19th century by navigators, such as Wachusett Reef, whose existence is doubtful. Types Ocean banks may be of volcanic nature. Banks may be carbonate or terrigenous. In tropical areas some banks are submerged atolls. As they are not associated with any landmass, banks have no outside source of sediments. Carbonate banks are typically platforms, rising from the ocean depths, whereas terrigenous banks are elevated sedimentary deposits. Seamounts, by ...

Newport, Oregon
Newport is a city in Lincoln County, Oregon, United States. It was incorporated in 1882, though the name dates back to the establishment of a post office in 1868. Newport was named for Newport, Rhode Island. As of the 2010 census, the city had a total population of 9,989, an increase of nearly 5% over its 2000 population; as of 2019, it had an estimated population of 10,853. The area was originally home to the Yacona tribe, whose history can be traced back at least 3000 years. White settlers began homesteading the area in 1864. The town was named by Sam Case, who also became the first postmaster. Newport has been the county seat of Lincoln County since 1952, when voters approved a measure to move the center of government from nearby Toledo to Newport. It is also home of the Oregon Coast Aquarium, Hatfield Marine Science Center, Nye Beach, Yaquina Head Light, Yaquina Bay Light, Pacific Maritime Heritage Center and Rogue Ales, and is notable as the western terminus of U.S ...

Nehalem Bank
Nehalem Bank is a bar, off the coast of Oregon, United States. It also has both rocky reefs and mud habitat, and is just northwest of Garibaldi Reef. Nehalem Bank runs between and deep, having an area of . It is located off Tillamook Head, hence is off Clatsop County, and is barely south of the mouth of the Columbia River and Astoria Canyon. Nehalem Bank is north of Nehalem Bay. Nehalem Bank is one of the three major offshore banks of Oregon, the other two being Heceta Bank and Coquille Bank. Nehalem Bank compares in size to Heceta Bank. Fishing Nehalem Bank has been trawled, for shrimp. As of 2020, it is illegal to fish the Nehalem Bank with bottom trawl gear. Oceanography and Geology Nehalem Bank has underwater sea stacks and paleoshorelines. There are rocky remnants of former seacliffs which are bored with intertidal pholad clam holes, testifying to what the level of the sea once was. Methane seeps are found, on Nehalem Bank, also, on Heceta Bank and Coqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metridium Giganteum
''Metridium farcimen'' is a species of sea anemone in the family Metridiidae. It is commonly known as the giant plumose anemone or white-plumed anemone. It is found in the eastern Pacific Ocean from Alaska down to Catalina Island, California. Taxonomy In 1990, Fautin et al. examined the validity of the name ''Metridium giganteum''. A further study in 2000 concluded that ''Actinia priapus''; Tilesius, 1809, ''Actinia farcimen''; Brandt, 1835, and ''Isometridium rickettsi''; Carlgren, 1949 were all synonyms of ''Metridium giganteum''. Of these, ''Actinia farcimen'' was the name first published. It is, however, a junior homonym so the valid name for the species is ''Metridium farcimen''; (Brandt, 1835). Description ''Metridium farcimen'' is a large sea anemone, occasionally reaching a height of one metre (39 in) when fully extended. More usually it is or less in height but is very variable in shape. It can retract its tentacles and form a ball up to in diameter. The colu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Anemone
Sea anemones are a group of predatory marine invertebrates of the order Actiniaria. Because of their colourful appearance, they are named after the '' Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional nourishment comes from a sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form ( DEM). It is often considered to include the graphic representat ...

Bathymetry
Bathymetry (; ) is the study of underwater depth of seabed, ocean floors (''seabed topography''), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetric (or hydrography, hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths) and selected depths (''Depth sounding, soundings''), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwa ...

Ratfish
Chimaeras are cartilaginous fish in the order Chimaeriformes , known informally as ghost sharks, rat fish, spookfish, or rabbit fish; the last three names are not to be confused with rattails, Opisthoproctidae, or Siganidae, respectively. At one time a "diverse and abundant" group (based on the fossil record), their closest living relatives are sharks and rays, though their last common ancestor with them lived nearly 400 million years ago. Today, they are largely confined to deep water. Description and habits Chimaeras live in temperate ocean floors down to deep, with few occurring at depths shallower than . Exceptions include the members of the genus ''Callorhinchus'', the rabbit fish and the spotted ratfish, which locally or periodically can be found at shallower depths. Consequently, these are also among the few species from the chimaera order kept in public aquaria. They live in all the oceans except for the Arctic and Antarctic oceans. They have elongated, soft b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatfish
A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. Many important food fish are in this order, including the flounders, soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Over 800 described species are placed into 16 families. Broadly, the flatfishes are divided into two suborders, Psettodoidei and Pleuronectoidei, with > 99% of the species diversity found within the Pleuronectoidei. The largest families are Soleidae, Bothidae and Cynoglossidae with more than 150 species each. There also exist two monotypic families ( Paralichthodidae and Oncopteridae). Some families ...
