Pamlico Sound
Pamlico Sound ( ) is a large estuarine lagoon in North Carolina. The largest lagoon along the North American East Coast, it extends long and wide. It is part of a large, interconnected network of similar lagoons that includes Albemarle Sound, Currituck Sound, Croatan Sound, Roanoke Sound, Pamlico Sound, Bogue Sound, Back Sound, and Core Sound known collectively as the Albemarle-Pamlico sound system. With over 3,000 sq. mi. (7,800 km2) of open water the combined estuary is second only in size to Chesapeake Bay in the United States. The Pamlico Sound is separated from the Atlantic Ocean by the Outer Banks, a row of low, sandy barrier islands that include Cape Hatteras National Seashore, Cape Lookout National Seashore, and Pea Island National Wildlife Refuge. The Albemarle-Pamlico Sound is one of nineteen great waters recognized by the America's Great Waters Coalition.

Bar (landform)
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material, and rises from the bed of a body of water close to the surface or above it, which poses a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar to, or quite different from, how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, the term refers to either any relatively shallow place in a stream, lake, sea, or other body of water; a rocky are ...

Parts-per Notation
In science and engineering, the parts-per notation is a set of pseudo-units to describe the small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are * parts-per-million - ppm, * parts-per-billion - ppb, * parts-per-trillion - ppt, * parts-per-quadrillion - ppq, This notation is not part of the International System of Units - SI system and its meaning is ambiguous. Applications Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water. The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Hatteras Inlet
Hatteras Inlet is an estuary in North Carolina, located along the Outer Banks, separating Hatteras Island and Ocracoke Island. It connects the Atlantic Ocean to the Pamlico Sound. Hatteras Inlet is located entirely within Hyde County, North Carolina, Hyde County. History The first "Hatteras Inlet" was formed south of the current inlet, but closed around 1764. The modern "Hatteras Inlet" was formed on September 7, 1846, by a violent gale. This massive storm was the same storm that opened present-day Oregon Inlet. The new inlet at Hatteras became a profitable inlet because it gave the Inner Banks, North Carolina, NC a quicker and easier route to travel to and from the Gulf Stream. It was easier to come into this inlet from the north than to Ocracoke Inlet, Ocracoke. Because of the increase in commerce, Hatteras, North Carolina, Hatteras Village Post Office was established in 1858. The initial invasion of the North Carolina coast on Hatteras Island during the American Civil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Inlet
Oregon Inlet is an inlet along North Carolina's Outer Banks. It joins the Pamlico Sound with the Atlantic Ocean and separates Bodie Island from Pea Island, which are connected by the Marc Basnight Bridge that spans the inlet. As one of the few access points to the ocean along this stretch of coast, Oregon Inlet is a major departure point for charter fishing trips, with a nearby harbor serving as the base for many large boats that travel miles out towards the Gulf Stream almost every day. The inlet is also the location of a U.S. Coast Guard motor lifeboat station. History Oregon Inlet was formed when a hurricane lashed the Outer Banks in 1846, separating Bodie Island from Pea Island. One ship that rode out that storm in Pamlico Sound was named the ''Oregon''. After the storm the crew members of this ship were the first to tell those on the mainland about the inlet's formation. Hence, it has been known as ''Oregon'' Inlet ever since. Like many other inlets along the Outer Bank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tar River
The Tar River is a river that is approximately long, in northeast North Carolina flowing generally southeast to an estuary of Pamlico Sound. The Tar River becomes the tidal Pamlico River once it passes under the U.S. Highway 17 Bridge in Washington, North Carolina. North Carolina was originally a naval stores colony—that is, the blanket of longleaf pines that covered the coastal plain was used by the British Navy for ships' masts and the pine pitch was used to manufacture tar caulking for vessels. The river derives its name from its historic use as a major route for tar-laden barges as they headed to the sea. The city of Tarboro is on the banks of the river. Recent research conducted by East Carolina University, Greenville and Pitt County historians has uncovered documentation noting that before the Civil War, the North Carolina Legislature had appropriated funds to construct dams and locks on the Tar River in an attempt to facilitate almost year-round navigation for th ...

Neuse River
The Neuse River ( , Tuscarora: Neyuherú·kęʔkì·nęʔ) is a river rising in the Piedmont of North Carolina and emptying into Pamlico Sound below New Bern. Its total length is approximately , making it the longest river entirely contained in North Carolina. The Trent River joins the Neuse at New Bern. Its drainage basin, measuring in area, also lies entirely inside North Carolina. It is formed by the confluence of the Flat and Eno rivers prior to entering the Falls Lake reservoir in northern Wake County. Its fall line shoals, known as the ''Falls of the Neuse'', lie submerged under the waters of Falls Lake. This River also creates the beauty of the Neuse River Trail, a long greenway that stretches from Falls Lake Dam, Raleigh, North Carolina to Legend Park, Clayton, North Carolina. Geography The Neuse begins at the confluence of the Flat and Eno rivers near Durham, North Carolina. The river enters Pamlico Sound just east of Maw Point Shoal near Hobucken, North Ca ...

Channel (geography)
In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While ''channel'' typically refers to a natural formation, the cognate term ''canal'' denotes a similar artificial structure. Channels are important for the functionality of ports and other bodies of water used for Navigability, navigability for shipping. Naturally, channels will change their depth and capacity due to erosion and Deposition (geology), deposition processes. Humans maintain navigable channels by dredging and other engineering processes. By extension, the term also applies to fluids other than water, e.g., lava channels. The term is also traditionally used to describe the Venusian channels, waterless surface features on Venus. Formation Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks.Bierman, R. B, David R. Montgomery (2014). Key Concepts in Geom ...

North
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating Direction (geometry), direction or geography. Etymology The word ''north'' is etymology, related to the Old High German ''nord'', both descending from the Proto-Indo-European language, Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Ancient Greek, Greek ''boreas'' "north wind, north" which, according to Ovid, was personified as the wind-god Boreas (god), Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. ...
