Scallop Dredge
A fishing dredge, also known as a scallop dredge or oyster dredge, is a kind of dredge which is towed along the bottom of the sea by a fishing boat in order to collect a targeted edible bottom-dwelling species. The gear is used to fish for scallops, oysters and other species of clams, crabs, and sea cucumber.Moore G., Jennings S. & Croxall J. (2000''Commercial Fishing: The Wider Ecological Impacts.''British Ecological Society. . Page 14 The dredge is then winched up into the boat and emptied. Dredges are also used in connection with the work of the naturalist in marine biology, notably on the Challenger Expedition. Construction The dredge is usually constructed from a heavy steel frame in the form of a scoop. The frame is covered with chain mesh which is open on the front, which is towed. The chain mesh functions as a net. Dredges may or may not have teeth along the bottom bar of the frame. In Europe, early dredges had teeth, called tynes, at the bottom. These teeth rake ...

NOAA
The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone. The agency is part of the United States Department of Commerce and is headquartered in Silver Spring, Maryland. History NOAA traces its history back to multiple agencies, some of which are among the earliest in the federal government: * United States Coast and Geodetic Survey, formed in 1807 * Weather Bureau of the United States, formed in 1870 * Bureau of Commercial Fisheries, formed in 1871 (research fleet only) * Coast and Geodetic Survey Corps, formed in 1917 The most direct predecessor of NOAA was the Environmental Science Services Administration (ESSA), into which several existing scientific agencies such as the ...

Octopus
An octopus (: octopuses or octopodes) 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 centre point of the eight limbs. An octopus can radically deform its shape, enabling it to squeeze through small gaps. They trail their appendages behind them as they swim. The siphon is used for respiration and locomotion (by water jet propulsion). Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse invertebrates. Octopuses inhabit various ocean habitats, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, and are short-lived. In most species, the male uses a speciall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Napier Hemy
Charles Napier Hemy (Newcastle upon Tyne, 24 May 1841 – 30 September 1917, Falmouth, Cornwall, Falmouth) was a British genre and marine painter. He was born to a musical family in Newcastle upon Tyne, and trained in the Government School of Design, Newcastle, followed by the Antwerp Academy and the studio of Jan August Hendrik Leys, Baron Leys. Hemy returned to London in the 1870s, and in 1881 moved to the coastal town of Falmouth, Cornwall, Falmouth in Cornwall. He produced painted figure- and landscapes, but his best-known works are ''Pilchards'' (1897) and ''London River'' (1904) which are in the Tate Britain, Tate collections. John Singer Sargent painted a portrait (now in the Falmouth Art Gallery collection) of Hemy when visiting Hemy's Falmouth home, 'Churchfield', in 1905. The visit highlighted the importance of the circle of artists that surrounded the great marine artist in the town. Hemy was elected an Associate of the Royal Academy in 1898 and an Academician in ...

Works Progress Administration
The Works Progress Administration (WPA; from 1935 to 1939, then known as the Work Projects Administration from 1939 to 1943) was an American New Deal agency that employed millions of jobseekers (mostly men who were not formally educated) to carry out public works projects, including the construction of public buildings and roads. It was set up on May 6, 1935, by presidential order, as a key part of the Second New Deal. The WPA's first appropriation in 1935 was $4.9 billion (about $15 per person in the U.S., around 6.7 percent of the 1935 GDP). Headed by Harry Hopkins, the WPA supplied paid jobs to the unemployed during the Great Depression in the United States, while building up the public infrastructure of the US, such as parks, schools, and roads. Most of the jobs were in construction, building more than of streets and over 10,000 bridges, in addition to many airports and much housing. In 1942, the WPA played a key role in both building and staffing Internment of Japanes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Childe Hassam
Frederick Childe Hassam (; October 17, 1859 – August 27, 1935) was an American Impressionist painter, noted for his urban and coastal scenes. Along with Mary Cassatt and John Henry Twachtman, Hassam was instrumental in promulgating Impressionism to American collectors, dealers, and museums. He produced over 3,000 paintings, oils, watercolors, etchings, and Lithography, lithographs over the course of his career, and was an influential American artist of the early 20th century.

John Henry Twachtman
John Henry Twachtman (August 4, 1853 – August 8, 1902) was an American painter best known for his impressionist landscapes, though his painting style varied widely through his career. Art historians consider Twachtman's style of American Impressionism to be among the more personal and experimental of his generation. He was a member of "The Ten," a loosely-allied group of American artists dissatisfied with professional art organizations, who banded together in 1898 to exhibit their works as a stylistically unified group. Studies Twachtman was born in Cincinnati, Ohio and received his first art training there, including studying under Frank Duveneck. Like many other gifted and driven artists of his generation, including Henry Ossawa Tanner and Diego Rivera, he sought his training in Europe. He enrolled in the Academy of Fine Arts in Munich in 1875 and visited Venice with Duveneck and William Merritt Chase in 1878. His landscapes from this time exhibit the loosely brushed, shad ...

Ballina, New South Wales
Ballina () is a town in the Northern Rivers region of New South Wales, Australia, and the seat of the Ballina Shire local government area. It lies north of Sydney and south of Brisbane. Ballina's urban population at the end of 2021 was 46,190. The town lies on the Richmond River and serves as a gateway to Byron Bay. History Ballina is located on the ancestral land of the Bundjalung people, who are its traditional owners and original inhabitants. Archaeological evidence demonstrates Bundjalung occupation of the region for at least 6000 years. One view suggests that the name Ballina comes from corruption of a clan name for the ''Bullina'' or ''Bul-loona'' band of the Arakwal. It has been argued that in this tribe's Bundjalung language, meant "place of many oysters". This theory argues that the Aboriginal name reminded the predominantly Irish settlers of "Ballina", so the name's origin could be an accidental or deliberate corruption. Another view is that town's name comes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Benthic
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 the Ancient Greek word (), 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, known as bottom dwellers, 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 ...

Fishing Vessel
A fishing vessel is a boat or ship used to fishing, catch fish and other valuable nektonic aquatic animals (e.g. shrimps/prawns, krills, coleoids, etc.) in the sea, lake or river. Humans have used different kinds of surface vessels in commercial fishing, commercial, artisan fishing, artisanal and recreational fishing. Prior to the 1950s there was little standardisation of fishing boats. Designs could vary between localities and even different boatyards. Traditional fishing boats were built of wood, which is not often used nowadays because of higher maintenance costs and lower durability. Fibreglass is used increasingly in smaller fishing vessels up to 25 metres (100-tonne displacement), while steel is usually used on vessels above 25 metres. It is difficult to estimate the number of recreational boat fishing, recreational fishing boats. They range in size from small dinghies, sailboats and motorboats to large superyachts and chartered cruiseliners. Unlike commercial fishing vess ...

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] |
