Chenier
A chenier or chénier is a sandy or shelly beach ridge that is part of a strand plain, called a “chenier plain,” consisting of cheniers separated by intervening mud-flat deposits with marsh and swamp vegetation. Cheniers are typically 1 to 6 m high, tens of km long, hundreds of metres wide, and often wooded. Chenier plains can be tens of km wide. Cheniers and associated chenier plains are associated with shorelines characterized by generally low wave energy, low gradient, muddy shorelines, and abundant sediment supply. The name is derived from the French word for wood, “chêne,” meaning oak, which grows on chenier ridges within southwest Louisiana.Goodie, A.S. (2004) ''Encyclopedia of Geomorphology'' Routledge.

Cameron Parish
Cameron Parish (french: Paroisse de Cameron) is a parish in the southwest corner of the U.S. state of Louisiana. As of the 2020 census, the population was 5,617. The parish seat is Cameron. Although it is the largest parish by area in Louisiana, it has the second-smallest population in the state, ahead of only Tensas. Cameron Parish is part of the Lake Charles, metropolitan statistical area. History This was part of La Louisiane, colonized by the French beginning in the 17th and early 18th century. They encountered the Atakapa and Choctaw indigenous peoples, who had occupied this area for thousands of years. In the late 1700s, after France had ceded New France (Canada) and other holdings east of the Mississippi River to Great Britain following its defeat in 1763 in the Seven Years' War, a number of French-speaking refugee families from Acadia settled in this part of coastal Louisiana. Some had fought against the British with Indian allies during the war in Acadia. Among the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Isle, Louisiana
Grand Isle is a town in Jefferson Parish in the U.S. state of Louisiana, located on a barrier island of the same name in the Gulf of Mexico. The island is at the mouth of Barataria Bay where it meets the gulf. The town of Grand Isle is statistically part of the New Orleans− Metairie−Kenner metropolitan statistical area, though it is not connected to New Orleans' continuous urbanized area. The population was 1,005 as of the 2020 U.S census, down from 1,296 from the previous 2010 U.S census. Grand Isle's main street is the seaside start of Louisiana Highway 1 (LA 1), which stretches away to the northwest corner of the state, ending near Shreveport. LA 1's automobile causeway at the west end of the island is the only land access to or from Grand Isle. Direct access to Grand Isle's seat of parish government is away in suburban Jefferson Parish. History Grand Isle has been repeatedly pummeled by hurricanes throughout its history. On average, the town and barrier island of ...

Cheniere Caminada, Louisiana
Cheniere Caminada was a fishing community located in Jefferson Parish, Louisiana, that was destroyed by what is considered one of the deadliest United States hurricanes, that was unnamed but referred to as the 1893 Cheniere Caminada hurricane. The community was located west of Grand Isle, which was almost destroyed by the same hurricane. The geographically isolated multi-ethnic fishing village of between 1,500 and 1,600 inhabitants provided seafood to restaurants in New Orleans. In the aftermath of the hurricane 779 lost their lives and over 2,000 were killed by the time the hurricane dissipated. Some residents decided to rebuild but later hurricanes took their toll on the community and there is not much remaining of the once thriving village. Community By 1893 the geographically isolated and predominantly French speaking community had between 1,500 and 1,600 men, women, and children that included Creoles from New Orleans, Acadians from Lafourche Parish Lafourche Parish ( ...

Hurricane Rita
Hurricane Rita was the most intense tropical cyclone on record in the Gulf of Mexico and the fourth-most intense Atlantic hurricane ever recorded. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten List of the most intense tropical cyclones#North Atlantic Ocean, most intense Atlantic hurricanes in terms of barometric pressure ever recorded (along with Hurricane Wilma, Wilma and Hurricane Katrina, Katrina), Rita was the seventeenth named storm, tenth hurricane, and fifth major hurricane of the 2005 Atlantic hurricane season, season. It was also the earliest-forming 17th named storm in the Atlantic until 2020 Atlantic hurricane season#Tropical Storm Rene, Tropical Storm Rene in 2020. Rita formed near The Bahamas from a tropical wave on September 18, 2005 that originally developed off the coast of West Africa. It moved westward, and after passing through the Florida Straits, Rita entered an environment of abnormally warm waters. Movi ...

Hurricane Audrey
Hurricane Audrey was one of the deadliest tropical cyclones in U.S. history, killing at least 416 people in its devastation of the southwestern Louisiana coast in 1957. Along with Hurricane Alex in 2010, it was also the strongest June hurricane ever recorded in the Atlantic basin as measured by pressure. The rapidly developing storm struck southwestern Louisiana as an intense Category 3 hurricane, destroying coastal communities with a powerful storm surge that penetrated as far as inland. Audrey was the first named storm and hurricane of the 1957 hurricane season. It formed on June 24 from a tropical wave that moved into the Bay of Campeche. Situated within ideal conditions for tropical development, Audrey quickly strengthened, reaching hurricane status a day afterwards. Moving north, it continued to strengthen and accelerate as it approached the United States Gulf Coast. On June 27, the hurricane reached peak sustained winds of 125 mph (205 k ...

Strand Plain
A strand plain or strandplain is a broad belt of sand along a shoreline with a surface exhibiting well-defined parallel or semi-parallel sand ridges separated by shallow swales. A strand plain differs from a barrier island in that it lacks either the lagoons or tidal marshes that separate a barrier island from the shoreline to which the strand plain is directly attached. Also, the tidal channels and inlets which cut through barrier islands are absent. Strand plains typically are created by the redistribution by waves and longshore currents of coarse sediment on either side of a river mouth. Thus, they are part of one type of wave-dominated delta.McCubbin, D.G., 1982, ''Barrier-island and strand-plain facies.'' in P.A. Scholle, and D.

Deposition (geology)
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment. Deposition occurs when the forces responsible for sediment transportation are no longer sufficient to overcome the forces of gravity and friction, creating a resistance to motion; this is known as the null-point hypothesis. Deposition can also refer to the buildup of sediment from organically derived matter or chemical processes. For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which has induced chemical processes (diagenesis) to deposit further calcium carbonate. Similarly, the formation of coal begins with the deposition of organic material, mainly from plants, in anaerobic conditions. Null-point hypothesis The null ...

Beach Ridge
A beach ridge is a wave-swept or wave-deposited ridge running parallel to a shoreline. It is commonly composed of sand as well as sediment worked from underlying beach material. The movement of sediment by wave action is called ''littoral transport''. Movement of material parallel to the shoreline is called ''longshore transport''. Movement perpendicular to the shore is called ''on-offshore transport''. A beach ridge may be capped by, or associated with, sand dunes. The height of a beach ridge is affected by wave size and energy. A fall in water level (or an uplift of land) can isolate a beach ridge from the body of water that created it. Isolated beach ridges may be found along dry lakes in the western United States and inland of the Great Lakes of North America, where they formed at the end of the last ice age when lake levels were much higher due to glacial melting and obstructed outflow caused by glacial ice. Some isolated beach ridges are found in parts of Scandinavia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Truth
Ground truth is information that is known to be real or true, provided by direct observation and measurement (i.e. empirical evidence) as opposed to information provided by inference. Etymology The ''Oxford English Dictionary'' (s.v. "ground truth") records the use of the word "Groundtruth" in the sense of a "fundamental truth" from Henry Ellison's poem "The Siberian Exile's Tale", published in 1833. Statistics and machine learning "Ground truth" may be seen as a conceptual term relative to the knowledge of the truth concerning a specific question. It is the ideal expected result. This is used in statistical models to prove or disprove research hypotheses. The term "ground truthing" refers to the process of gathering the proper objective (provable) data for this test. Compare with gold standard. For example, suppose we are testing a stereo vision system to see how well it can estimate 3D positions. The "ground truth" might be the positions given by a laser rangefinder which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Godwit
The godwits are a group of large, long-billed, long-legged and strongly migratory waders of the bird genus ''Limosa''. Their long bills allow them to probe deeply in the sand for aquatic worms and molluscs. In their winter range, they flock together where food is plentiful. They frequent tidal shorelines, breeding in northern climates in summer and migrating south in winter. A female bar-tailed godwit made a flight of 29,000 km (18,000 mi), flying of it without stopping. In 2020 a male bar-tailed godwit flew about non-stop in its migration from Alaska to New Zealand, previously a record for avian non-stop flight. In October 2022, a 5 month old, male bar-tailed godwit was tracked from Alaska to Tasmania, a trip that took 11 days, and recorded a non-stop flight of . The godwits can be distinguished from the curlews by their straight or slightly upturned bills, and from the dowitchers by their longer legs. The winter plumages are fairly drab, but three species have r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
