San Luis Pass (Galveston Island)
San Luis Pass is a passage of water on the Texas Gulf Coast of the United States. It connects the sheltered waters of West Bay to the open Gulf of Mexico between Galveston Island and San Luis Island. Fishermen and swimmers have been killed in the Pass' treacherous waters. The Gulf of Mexico-West Bay pass transitions vast volumes of seawater. The San Luis Pass physical oceanography is essentially contributed to the aggressive Gulf Stream and loop current, fluctuating tides in marginal sea, and marine sediment. The marginal sea's ocean circulation is periodically redefining the coastal continental shelf subsequently reciprocating uncertainties of continental margin at Follet's Island and West Galveston Island. The San Luis Pass-Vacek Toll Bridge spans San Luis Pass from Galveston County to Brazoria County. Characteristics Tide levels can vary by almost 2 feet in height, although the tidal effects seem more pronounced along straits than other barrier island zones. Water curr ...

Inlet
An inlet is a typically long and narrow indentation of a shoreline such as a small arm, cove, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea. Overview In marine geography, the term "inlet" usually refers to either the actual channel between an enclosed bay and the open ocean and is often called an "entrance", or a significant recession in the shore of a sea, lake or large river. A certain kind of inlet created by past glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes. Multi-arm complexes of large inlets or fjords may be called sound In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the br ...s, e.g., Puget Sound, Howe Sound, Karmsund (' ...

Tides In Marginal Seas
Tides in marginal seas are tides affected by their location in semi-enclosed areas along the margins of continents and differ from tides in the open oceans. Tide, Tides are water level variations caused by the gravitational interaction between the Moon, the Sun and the Earth. The resulting tidal force is a secondary effect of gravity: it is the difference between the actual Gravitational Force, gravitational force and the centrifugal force. While the centrifugal force is constant across the Earth, the gravitational force is dependent on the distance between the two bodies and is therefore not constant across the Earth. The tidal force is thus the difference between these two forces on each location on the Earth. In an idealized situation, assuming a planet with no landmasses (an Ocean world, aqua planet), the tidal force would result in two tidal bulges on opposite sides of the earth. This is called the equilibrium tide. However, due to global and local ocean responses different ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

1949 Texas Hurricane
The 1949 Texas hurricane was a tropical cyclone that crossed over from the eastern Pacific to the Atlantic, contributing to extensive flooding in Guatemala and impacting East Texas. Forming in the Pacific Ocean on September 27, the storm meandered across Central America and southern Mexico as a tropical depression. Rainfall from the developing storm helped exacerbate a flooding event over southern Guatemala that may have killed as many as 40,000 people. The storm then crossed into the Gulf of Mexico on October 1 and began to intensify. It ultimately peaked as a high-end Category 2-equivalent hurricane on the modern-day Saffir–Simpson hurricane scale and made landfall near Freeport, Texas, on the morning of October 4. It rapidly weakened after moving inland and dissipated several days later. Damage from the storm was moderate, although the hurricane temporarily cut off the city of Galveston from the mainland. Rice crops suffered extensive damage in Texas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Electronic Toll Collection
Electronic toll collection (ETC) is a wireless system to automatically collect the usage fee or Road pricing, toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. It is a faster alternative which is replacing Toll house, toll booths, where vehicles must stop and the driver manually pays the toll with cash or a card. In most cases, vehicles using the system are equipped with an automated radio transponder device. When the vehicle passes a roadside toll reader device, a radio signal from the reader triggers the transponder, which transmits back an identifying number which registers the vehicle's use of the road, and an electronic payment system charges the user the toll. A major advantage is the driver does not have to stop, reducing traffic delays. Electronic tolling is cheaper than a staffed toll booth, reducing transaction costs for government or private road owners. The ease of varying the amount of the toll makes it easy to implement road conge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Surfside Beach, Texas
Surfside Beach, also known locally as Surfside, is a city in Brazoria County, Texas, United States, that is situated on Follet's Island by the Gulf of Mexico near the city of Freeport. The population was 640 at the 2020 census. The city has claimed the "Cradle of Texas Liberty" title due to the fact that the Treaty of Velasco which ended hostilities between Texas and Mexico was signed at Fort Velasco, which was located near the city's current City Hall. Former Congressman Ron Paul maintained a home near Surfside Beach before selling it on Facebook in 2011. Surfside Beach has been criticized for having some of the worst coastal waters in the United States, having levels of Enterococcus bacteria greater than 104cfu/100ml, providing very little, if not no access to the main beach it'self. Geography Surfside Beach is located in southern Brazoria County on the southwestern tip of Follet's Island at . It is bordered to the southeast by the Gulf of Mexico and to the southwest ...

Hurricane Ike (2008)
Hurricane Ike () was a powerful tropical cyclone that swept through portions of the Greater Antilles and Northern America in September 2008, wreaking havoc on infrastructure and agriculture, particularly in Cuba and Texas. Ike took a similar track to the 1900 Galveston hurricane. The ninth tropical storm, fifth hurricane, and third major hurricane of the 2008 Atlantic hurricane season, Ike developed from a tropical wave west of Cape Verde on September 1 and strengthened to a peak intensity as a Category 4 hurricane over the open waters of the central Atlantic on September 4 as it tracked westward. Several fluctuations in strength occurred before Ike made landfall on eastern Cuba on September 8. The hurricane weakened prior to continuing into the Gulf of Mexico, but increased its intensity by the time of its final landfall in Galveston, Texas, on September 13 before becoming an extratropical storm on September 14. The remnants of Ike cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Barrier Island
Barrier islands are a Coast#Landforms, coastal landform, a type of dune, dune system and sand island, where an area of sand has been formed by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend for hundreds of kilometers, with islands periodically separated by tidal inlets. The longest barrier island in the world is Padre Island of Texas, United States, at long. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. Though many are long and narrow, the length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave ener ...

Chart Datum
A chart datum is the water surface serving as origin (or coordinate surface) of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. Common chart datums are ''lowest astronomical tide'' (LAT)Australian Bureau of MeteorologNational Tide Centre Glossary(retrieved 30 April 2013) and ''mean lower low water'' (MLLW). In non-tidal areas, e.g. the Baltic Sea, mean sea level (MSL) is used. A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart. However, it is necessarily an equigeopotential (a water "level surface"): the chart datum is tilted across smaller to larger tidal range regions; in rivers, it is a sloping and undulating surface following the low stage. Definitions The following tidal phases are commonly used in the definition of chart datums. Lowest and highest astronomical tide ...

Continental Margin
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area. Subzones The continental shelf is the relatively shallow water area found in proximity to continents; it is the portion of the continental margin that transitions from the shore out towards to ocean. Continental shelves are believed to make up 7% of the sea floor. The width of continental shelves worldwide varies in the range of 0.03–1500 km. The continental shelf is generally flat, and ends at the shelf break, where there is a drastic increase in slope angle: The mean angle of continental shelves worldwide is 0° 07′, and typically steeper closer to the c ...

Uncertainty
Uncertainty or incertitude refers to situations involving imperfect or unknown information. It applies to predictions of future events, to physical measurements that are already made, or to the unknown, and is particularly relevant for decision-making. Uncertainty arises in partially observable or stochastic environments, as well as due to ignorance, Laziness, indolence, or both. It arises in any number of fields, including insurance, philosophy, physics, statistics, economics, finance, medicine, psychology, sociology, engineering, metrology, meteorology, ecology and information science. Concepts Although the terms are used in various ways among the general public, many specialists in decision theory, statistics and other quantitative fields have defined uncertainty, risk, and their measurement as: Uncertainty The lack of certainty, a state of limited knowledge where it is impossible to exactly describe the existing state, a future outcome, or more than one possible outcome. ...
