Fishing Dredger
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 raked or ...

Starfish
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea (). Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube feet operated by a hydraulic system and a mouth at the centre of the oral or lower surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Works Progress Administration
The Works Progress Administration (WPA; renamed in 1939 as the Work Projects Administration) 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 620,000 miles (1,000,000 km) of streets and over 10,000 bridges, in addition to many airports and much housing. The largest single project of the WPA was the Tennessee Valley Authority. At its peak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Rummler
Alexander Joseph Rummler (July 25, 1867 – 1959) was an American painter best known for his work on murals and billboards. Rummler was born in Dubuque, Iowa to German immigrants Joseph and Rosalia Rummler. In 1888 Rummler traveled to New York to study art at the Art Students League of New York.

He moved to South Norwalk, Connecticut in 1907. Rummler became known nationwide at the end of World War I when his painting of the signing of the armistice was displayed on billboards. In 1926 he was chosen to represent Connecticut in the Philadelphia Exposition of 1926, where his paintings took first place. In 1936 Rummler began working for the Works Progress Administration painting murals for the then still under construction Norwalk High School. He painted sixteen murals and eight smaller panels depicting life in Norwalk. ... [...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 lithographs over the course of his career, and was an influential American artist of the early 20th century. Early years Hassam was known to all as "Childe" (pronounced like ''child''), a name taken from an uncle. Hassam was born in the family home on Olney Street on Meeting House Hill in the Dorchester neighborhood of Boston, on October 17, 1859. His father, Frederick Fitch Hassam (1825–1880), was a moderately successful cutlery businessman with a large collection of art and antiques. He descended from a long line of New Englanders. His mother, Rosa Delia Hawthorne (1832–1880), a native of Maine, shared an ancestor wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Skipjack (boat)
The skipjack is a traditional fishing boat used on the Chesapeake Bay for oyster dredging. It is a sailboat which succeeded the bugeye as the chief oystering boat on the bay, and it remains in service due to laws restricting the use of powerboats in the Maryland state oyster fishery. Design and construction The skipjack is sloop-rigged, with a sharply raked mast and extremely long boom (typically the same length as the deck of the boat). The mainsail is ordinarily triangular, though gaff rigged examples were built. The jib is self-tending and mounted on a bowsprit. This sail plan affords the power needed to pull the dredge, particularly in light winds, while at the same time minimizing the crew required to handle the boat. The hull is wooden and V-shaped, with a hard chine and a square stern. In order to provide a stable platform when dredging, skipjacks have very low freeboard and a wide beam (averaging one third the length on deck). A centerboard is mounted in lieu of a kee ...

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 ancient Greek, βένθος (bénthos), 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 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 shore line (intertidal ...

Fishing Vessel
A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing. The total number of fishing vessels in the world in 2016 was estimated to be about 4.6 million, unchanged from 2014. The fleet in Asia was the largest, consisting of 3.5 million vessels, accounting for 75 percent of the global fleet. In Africa and North America the estimated number of vessels declined from 2014 by just over 30,000 and by nearly 5,000, respectively. For Asia, Latin America and the Caribbean and Oceania the numbers all increased, largely as a result of improvements in estimation procedures.FAO 2007 It is difficult to estimate the number of recreational fishing boats. They range in size from small dinghies to large charter cruisers, and unlike commercial fishing vessels, are often not dedicated just to fishing. Prior to the 1950s there was little standardisation of fishing boats. Desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
