Pamlico Sound
Pamlico Sound ( ) is a lagoon in North Carolina which is the largest lagoon along the North American East Coast, extending long and 15 to 20 miles (24 to 32 km) wide. It is part of a large, interconnected network of lagoon estuaries that includes Albemarle Sound, Currituck Sound, Croatan Sound, Roanoke Sound, Pamlico Sound, Bogue Sound, Back Sound, and Core Sound. Together, these sounds, known as the Albemarle-Pamlico sound system, comprise the second largest estuary in the United States, covering over 3,000 sq. mi. (7,800 km2) of open water. (Chesapeake Bay is the largest.) 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. Hydrology Pamlico Sound is connected to the north with Albem ...

Cape Hatteras National Seashore
Cape Hatteras National Seashore is a United States national seashore which preserves the portion of the Outer Banks of North Carolina from Bodie Island to Ocracoke Island, stretching over , and is managed by the National Park Service. Included within this section of barrier islands along N.C. 12, but outside the national seashore boundaries, are Pea Island National Wildlife Refuge and several communities, such as Rodanthe, Buxton, and Ocracoke. Cape Hatteras is a combination of natural and cultural resources, and provides a wide variety of recreational opportunities. Once dubbed the "Graveyard of the Atlantic" for its treacherous currents, shoals, and storms, Cape Hatteras has a wealth of history relating to shipwrecks, lighthouses, and the US Lifesaving Service. The islands also provide a variety of habitats and are a valuable wintering area for migrating waterfowl. The park's fishing and surfing are considered the best on the East Coast.

Parts-per Notation
In science and engineering, the parts-per notation is a set of pseudo-units to describe 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, ) and parts-per-quadrillion (ppq, ). This notation is not part of the International System of Units (SI) system and its meaning is ambiguous. Overview 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. Therefore, it is common to equat ...

Salinity
Salinity () is the saltiness or amount of 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 ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a 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 sodium bicarbonate which dissolve into ions ...

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. 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, 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. Because of the increase in commerce, Hatteras Village Post Office was established in 1858. The initial invasion of the North Carolina coast on Hatteras Island during the Civil War, called the Battle of Hatteras Inlet Batteries, came from Hatteras Inlet on August 28– ...

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 2.8 mile 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. Akin to many other inlets along the Outer ... [...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 underpasses the U.S. Highway 17 Bridge in Washington, North Carolina. North Carolina was originally a naval stores colony—that is, the blanket of long leaf 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 the far ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

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 Carolina ...

Channel (geography)
In physical geography, a channel is a type of landform consisting of the outline of a path of relatively shallow and narrow body of water or of other fluids (e.g., lava), most commonly the confine of a river, river delta or strait. The word is cognate to canal, and sometimes takes this form, e.g. the Hood Canal. 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 Geomorphology. W. H. Freeman and Company Publishers. United States. This site is referred to as the channel head and it marks an important boundary between hillslope processes and fluvial processes. The channel head is the most upslope part of a channel network and is defined by flowing water between defined identifiable banks. A channel head forms as overland flow and/or subsurface flow accumulate to a point where shear stress can overcome erosion resistance of the ground surface. Channel he ...
