Intracoastal Waterway

Intracoastal Waterway

The Intracoastal Waterway is a 4,800 km (3,000 mile) long recreational and commercial waterway along the Atlantic and Gulf coasts of the United States. Some lengths are natural and others are man made. One of the older portions is the Dismal Swamp Canal in the Great Dismal Swamp in Virginia and North Carolina. The waterway is toll-free, but commercial users pay a fuel tax that is used to maintain and improve it. The creation of the Intracoastal Waterway was first authorized by the United States Congress in 1919. It is maintained by the United States Army Corps of Engineers. Federal law provides for the waterway to be maintained at a minimum depth of 12 ft (4 m) for most of its length, but inadequate funding has prevented that from happening. Consequently, shoaling or shallow water are problems along several sections of the waterway; some parts have 7-ft (2.1-m) and 9-ft (2.7-m) minimum depths. The waterway consists of two non-contiguous segments: the Gulf Intracoastal Waterway, extending from Brownsville, Texas to Carrabelle, Florida, and the Atlantic Intracoastal Waterway, extending from Key West, Florida to Boston, Massachusetts. The two segments were originally intended to be connected via the Cross-Florida Barge Canal across northern Florida, but this was never completed due to environmental concerns. The Intracoastal Waterway has a good deal of commercial activity; barges haul petroleum, petroleum products, foodstuffs, building materials, and manufactured goods. It is also used extensively by recreational boaters.

Waterway

A waterway is any navigable body of water. These include rivers, lakes, oceans, and canals. In order for a waterway to be navigable, it must meet several criteria:
- The waterway must be deep enough to allow the draft depth of the vessels using it;
- The waterway must be wide enough to allow passage for the beam width of the vessels using it;
- The waterway must be free of barriers to navigation such as waterfalls and rapids, or have a way around them (such as canal locks);
- The current of the waterway must be mild enough to allow vessels to make headway. Vessels using waterways vary from small animal-drawn barges to immense ocean tankers and ocean liners, such as cruise ships. At one time, canals were built mostly for small wooden barges drawn by horses or other draft animals. Today, major canals are built to allow passage of large ocean-going vessels. See Ship Canal.

Atlantic Ocean

The Atlantic Ocean is Earth's second-largest ocean, covering approximately one-fifth of its surface. The ocean's name, derived from Greek mythology, means the "Sea of Atlas". This ocean occupies an elongated, S-shaped basin extending in a north-south direction and is divided into the North Atlantic and South Atlantic by equatorial counter currents at about 8° north latitude. Bounded by the Americas on the west and Europe and Africa on the east, the Atlantic is linked to the Pacific Ocean by the Arctic Ocean on the north and the Drake Passage on the south. An artificial connection between the Atlantic and Pacific is also provided by the Panama Canal. On the east, the dividing line between the Atlantic and the Indian Ocean is the 20° east meridian. The Atlantic is separated from the Arctic Ocean by a line from Greenland to northwestern Iceland and then from northeastern Iceland to southernmost tip of Spitsbergen and then to North Cape in northern Norway. Norway on a fair day.]] Covering approximately 20% of Earth's surface, the Atlantic Ocean is second only to the Pacific in size. With its adjacent seas it occupies an area of about 106,400,000 km² (41,100,000 square miles); without them, it has an area of 82,400,000 km² (31,800,000 mi²). The land area that drains into the Atlantic is four times that of either the Pacific or Indian oceans. The volume of the Atlantic Ocean with its adjacent seas is 354,700,000 km³ (85,100,000 mi³) and without them 323,600,000 km³ (77,640,000 mi³). The average depth of the Atlantic, with its adjacent seas, is 3,332 m (10,932 ft); without them it is 3,926 m (12,881 ft). The greatest depth, 8,605 m (28,232 ft), is in the Puerto Rico Trench. The width of the Atlantic varies from 2,848 km (1,770 miles) between Brazil and Liberia to about 4,830 km (3,000 miles) between the United States and northern Africa. The Atlantic Ocean has irregular coasts indented by numerous bays, gulfs, and seas. These include the Caribbean Sea, Gulf of Mexico, Gulf of St. Lawrence, Mediterranean Sea, Black Sea, North Sea, Labrador Sea, Baltic Sea, and Norwegian-Greenland Sea. Islands in the Atlantic Ocean include Faroe Islands, Greenland, Iceland, Rockall, Great Britain, Ireland, Fernando de Noronha, the Azores, the Madeira Islands, the Canaries, the Cape Verde Islands,Sao Tome e Principe, Newfoundland, Bermuda, the West Indies, Ascension, St. Helena, Trindade, Martin Vaz, Tristan da Cunha, the Falkland Islands, and South Georgia Island. South Georgia Island

Ocean bottom

The principal feature of the bottom topography of the Atlantic Ocean is a great submarine mountain range called the Mid-Atlantic Ridge. It extends from Iceland in the north to approximately 58° south latitude, reaching a maximum width of about 1,600 km (1,000 miles). A great rift valley also extends along the ridge over most of its length. The depth of water over the ridge is less than 2,700 m (8,900 ft) in most places, and several mountain peaks rise above the water, forming islands. The South Atlantic Ocean has an additional submarine ridge, the Walvis Ridge. The Mid-Atlantic Ridge separates the Atlantic Ocean into two large troughs with depths averaging between 3,700 and 5,500 m (12,000 and 18,000 ft). Transverse ridges running between the continents and the Mid-Atlantic Ridge divide the ocean floor into numerous basins. Some of the larger basins are the Guiana, North American, Cape Verde, and Canaries basins in the North Atlantic. The largest South Atlantic basins are the Angola, Cape, Argentina, and Brazil basins. The deep ocean floor is thought to be fairly flat, although numerous seamounts and some guyots exist. Several deeps or trenches are also found on the ocean floor. The Puerto Rico Trench, in the North Atlantic, is the deepest. The Laurentian Abyss is found off the eastern coast of Canada. In the south Atlantic, the South Sandwich Trench reaches a depth of 8,428 m (27,651 ft). A third major trench, the Romanche Trench, is located near the equator and reaches a depth of about 7,454 m (24,455 ft). The shelves along the margins of the continents constitute about 11% of the bottom topography. In addition, a number of deep channels cut across the continental rise. Ocean sediments are composed of terrigenous, pelagic, and authigenic material. Terrigenous deposits consist of sand, mud, and rock particles formed by erosion, weathering, and volcanic activity on land and then washed to sea. These materials are largely found on the continental shelves and are thickest off the mouths of large rivers or off desert coasts. Pelagic deposits, which contain the remains of organisms that sink to the ocean floor, include red clays and Globigerina, pteropod, and siliceous oozes. Covering most of the ocean floor and ranging in thickness from 60 m to 3,300 m (200 ft to 11,000 ft), they are thickest in the convergence belts and in the zones of upwelling. Authigenic deposits consist of such materials as manganese nodules. They occur where sedimentation proceeds slowly or where currents sort the deposits.

Water characteristics

sediment The salinity of the surface waters in the open ocean ranges from 33 to 37 parts per thousand by mass and varies with latitude and season. Although the minimum salinity values are found just north of the equator, in general the lowest values are in the high latitudes and along coasts where large rivers flow into the ocean. Maximum salinity values occur at about 25° north latitude. Surface salinity values are influenced by evaporation, precipitation, river inflow, and melting of sea ice. Surface water temperatures, which vary with latitude, current systems, and season and reflect the latitudinal distribution of solar energy, range from less than −2 °C to 29 °C (28 °F to 84 °F). Maximum temperatures occur north of the equator, and minimum values are found in the polar regions. In the middle latitudes, the area of maximum temperature variations, values may vary by 7 °C to 8 °C (13 °F to 15 °F). The Atlantic Ocean consists of four major water masses. The North and South Atlantic central waters constitute the surface waters. The sub-Antarctic intermediate water extends to depths of 1,000 m (3,300 ft). The North Atlantic deep water reaches depths of as much as 4,000 m (13,200 ft). The Antarctic bottom water occupies ocean basins at depths greater than 4,000 m (13,200 ft). Within the North Atlantic, ocean currents isolate a large elongated body of water known as the Sargasso Sea, in which the salinity is noticeably higher than average. The Sargasso Sea contains large amounts of seaweed, and is also the spawning ground for the European eel. Due to the Coriolis effect, water in the North Atlantic circulates in a clockwise direction, whereas water circulation in the South Atlantic is counter clockwise. The South tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur during each 24 lunar hours. The tides are a general wave that moves from south to north. In latitudes above 40° north some east-west oscillation occurs.

Climate

diurnal The climate of the Atlantic Ocean and adjacent land areas is influenced by the temperatures of the surface waters and water currents as well as the winds blowing across the waters. Because of the oceans' great capacity for retaining heat, maritime climates are moderate and free of extreme seasonal variations. Precipitation can be approximated from coastal weather data and air temperature from the water temperatures. The oceans are the major source of the atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest climatic zones stretch across the Atlantic north of the equator. The coldest zones are in the high latitudes, with the coldest regions corresponding to the areas covered by sea ice. Ocean currents contribute to climatic control by transporting warm and cold waters to other regions. Adjacent land areas are affected by the winds that are cooled or warmed when blowing over these currents. The Gulf Stream, for example, warms the atmosphere of the British Isles and northwestern Europe, and the cold water currents contribute to heavy fog off the coast of northeastern Canada (the Grand Banks area) and the northwestern coast of Africa. In general, winds tend to transport moisture and warm or cool air over land areas. Hurricanes develop in the southern part of the North Atlantic Ocean.

History and economy

The Atlantic Ocean appears to be the second youngest of the world's oceans, after the Southern Ocean. Evidence indicates that it did not exist prior to 180 million years ago, when the continents that formed from the breakup of the ancestral supercontinent, Pangaea, were being rafted apart by the process of seafloor spreading. The Atlantic has been extensively explored since the earliest settlements were established along its shores. The Vikings, Portuguese, and Christopher Columbus were the most famous among its early explorers. After Columbus, European exploration rapidly accelerated, and many new trade routes were established. As a result, the Atlantic became and remains the major artery between Europe and the Americas (known as transatlantic trade). Numerous scientific explorations have been undertaken, including those by the German Meteor expedition, Columbia University's Lamont Geological Observatory, and the U.S. Navy Hydrographic Office. The ocean has also contributed significantly to the development and economy of the countries around it. Besides its major "transatlantic" transportation and communication routes, the Atlantic offers abundant petroleum deposits in the sedimentary rocks of the continental shelves and the world's richest fishing resources, especially in the waters covering the shelves. The major species of fish caught are cod, haddock, hake, herring, and mackerel. The most productive areas include the Grand Banks of Newfoundland, the shelf area off Nova Scotia, Georges Bank off Cape Cod, the Bahama Banks, the waters around Iceland, the Irish Sea, the Dogger Bank of the North Sea, and the Falkland Banks. Eel, lobster, and whales have also been taken in great quantities. All these factors, taken together, tremendously enhance the Atlantic's great commercial value. Because of the threats to the ocean environment presented by oil spills, marine debris, and the incineration of toxic wastes at sea, various international treaties exist to reduce some forms of pollution.
- In 1858, the first Transatlantic telegraph cable was laid by Cyrus Field.
- In 1919, the American NC-4 became the first airplane to cross the Atlantic (though it made a couple of landings on islands along the way).
- Later in 1919, a British airplane piloted by Alcock and Brown made the first non-stop transatlantic flight from Newfoundland to Ireland.
- In 1921, the British were the first to cross the North Atlantic in an airship.
- In 1922, the Portuguese were the first to cross the South Atlantic in an airship.
- The first transatlantic telephone call was made on January 7, 1927.
- In 1927, Charles Lindbergh made the first solo non-stop transatlantic flight in an airplane (between New York City and Paris).
- After rowing for 81 days and 2,962 miles, on December 3, 1999 Tori Murden became the first woman to cross the Atlantic Ocean by rowboat alone when she reached Guadeloupe from the Canary Islands.

Storms are common in the North Atlantic during northern winters, making ocean crossings more difficult and dangerous.

Terrain

The surface is usually covered with sea ice in the Labrador Sea, Denmark Strait, and Baltic Sea from October to June. There is a clockwise warm-water gyre (broad, circular system of currents) in the northern Atlantic, and a counter-clockwise warm-water gyre in the southern Atlantic. The ocean floor is dominated by the Mid-Atlantic Ridge, a rugged north-south centerline for the entire Atlantic basin, first discovered by the Challenger Expedition.

Elevation extremes


- lowest point: Milwaukee Deep in the Puerto Rico Trench -8,605 m
- highest point: sea level 0 m

Natural resources

Petroleum and gas fields, fish, marine mammals (seals and whales), sand and gravel aggregates, placer deposits, polymetallic nodules, precious stones

Natural hazards

Icebergs are common in the Davis Strait, Denmark Strait, and the northwestern Atlantic Ocean from February to August and have been spotted as far south as Bermuda and the Madeira Islands. Ships are subject to superstructure icing in extreme northern Atlantic from October to May. Persistent fog can be a maritime hazard from May to September. So can hurricanes north of the equator (May to December). The Bermuda Triangle is popularly believed to be the site of numerous aviation and shipping incidents, due to unexplained and supposedly mysterious causes, but coastguard records do not support this belief.

Current environmental issues

Endangered marine species include the manatee, seals, sea lions, turtles, and whales. Drift net fishing is killing dolphins, albatrosses and other seabirds (petrels, auks), hastening the decline of fish stocks and contributing to international disputes. There is municipal sludge pollution off eastern US, southern Brazil, and eastern Argentina, oil pollution in the Caribbean Sea, Gulf of Mexico, Lake Maracaibo, Mediterranean Sea, and North Sea, and industrial waste and municipal sewage pollution in the Baltic Sea, North Sea, and Mediterranean Sea.

Notes on geography

Major chokepoints include the Strait of Gibraltar and the Panama Canal; strategic straits include the Strait of Dover, Straits of Florida, Mona Passage, The Sound (Oresund), and Windward Passage; the Equator divides the Atlantic Ocean into the North Atlantic Ocean and South Atlantic Ocean (previously known as the Ethiopic Ocean). During the Cold War the so called Greenland-Iceland-UK (GIUK) Gap was a major strategic concern, the seabed in that area was laid with extensive hydrophone systems to track Soviet submarines.

Gulf of Mexico

The Gulf of Mexico is a major body of water bordered and nearly landlocked by North America. The gulf's eastern, north, and northwestern shores lie within the United States of America (specifically, the states of Florida, Alabama, Mississippi, Louisiana, and Texas); its southwestern and southern shores lie within Mexico (specifically, the states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo); on the southeast it is bordered by Cuba. It connects with the Atlantic Ocean via the Florida Straits between the U.S. and Cuba, and with the Caribbean Sea via the Yucatan Channel between Mexico and Cuba. (Note: In common usage, at least in the U.S., the term "Gulf Coast" usually refers to either the continuous portion of the coast running from Cape Sable, Florida, to Brownsville, Texas, or from Cape Sable, Florida, to the northern tip of the Yucatán Peninsula at Cabo Catoche, Quintana Roo. Both meanings exclude Cuba as well as the Florida Keys.) Florida Keys The total area of the Gulf of Mexico is approximately 615,000 mi² (1.6 million km²), the southern third of which lies within the tropics, and plunges to a depth of 2,080 fathoms (3804 m). This deepest part is Sigsbee Deep, an irregular trough more than 300 nautical miles (550 km) long, sometimes called the "Grand Canyon under the sea." The cooler water from the deep stimulates plankton growth, which attracts small fish, shrimp, and squid. [http://www.tsha.utexas.edu/handbook/online/articles/GG/rrg7.html 1] The Gulf Stream, a warm Atlantic Ocean current and one of the strongest ocean currents known, originates in the gulf. The gulf has been visited many times by powerful Atlantic hurricanes, some of which have caused extensive human death and other destruction (see 2005's Hurricane Katrina, for example). Tidal ranges are extremely small in the Gulf of Mexico due to the narrow connection with the ocean – much like the Mediterranean. The Bay of Campeche in Mexico constitutes a major arm of the Gulf of Mexico. Additionally, the gulf's shoreline is fringed by numerous bays and smaller inlets. A number of rivers empty into the gulf, most notably the Mississippi River. The land that forms the gulf's coast, including many long, narrow barrier islands, is almost uniformly low-lying and is characterized by marshes and swamps as well as stretches of sandy beach. The continental shelf is quite wide at most points along the coast. The shelf is exploited for its oil by means of offshore drilling rigs, most of which are situated in the western gulf. Another important commercial activity is fishing; major catches include various fishes as well as shrimp and crabs, with oysters being harvested on a large scale from many of the bays and sounds. Other important industries along the coast include shipping, petrochemical processing and storage, paper manufacture, and tourism. Coastal cities of note include Tampa, St. Petersburg, Pensacola, Mobile, New Orleans, Beaumont, and Houston (all in the U.S.), Tampico, Tuxpam, Veracruz and Mérida (in Mexico), and Havana (in Cuba). The gulf's coastal areas were first settled by Native American groups, including those representing several of the early advanced cultures of Mexico. During the period of European exploration and colonization the entire region became a theatre of contention between the Spanish, French and English. The present-day culture of the coastal region is primarily Spanish-American (Mexico, Cuba) and Anglo-American (U.S.). English A point of interest about the Gulf is that 65 million years ago, the Chicxulub crater was formed when a large meteorite hit the earth. It is hypothesized that this impact was the asteroid that caused the extinction of the dinosaurs. [http://web.ukonline.co.uk/a.buckley/dino.htm]

Pollution

Because of the ever increasing amount of nitrogen and phosphates dissolved in the waters of the Gulf of Mexico, pollution has more than doubled since 1950. Current estimates suggest that three times as much nitrogen is being carried into the Gulf today compared with levels 30 years ago or at any time in history. Blooms of photosynthesizers die and sink, and the processes of their decay exhausts the available supplies of oxygen dissolved in the water. Every summer there is now an area south of the Louisiana coastline, larger than the U.S. state of Massachusetts at over 7,000 mi² (18,000 km²) that is hypoxic. These waters do not carry enough oxygen to sustain marine life. This annually enlarging "dead zone" is a major threat to the fishing industry and to public health. Also, there are frequent "red tide" algae blooms that kill fish and marine mammals and cause respiratory problems in humans and some domestic animals when the blooms reach close to shore. This has especially been plaguing the southwest Florida coast, from the Keys to north of Pasco County, Florida.

Dismal Swamp Canal

Dismal Swamp Canal is located along the eastern edge of the Great Dismal Swamp in Virginia and North Carolina in the United States. It is the oldest continually operating man-made canal in the United States, opened in 1805 (and celebrating a Bicentennial in 2005). It is part of the Intracoastal Waterway, an inland route which parallels the east coast along the Atlantic Ocean from Boston, Massachusetts to Key West, Florida.

History

In the Colonial period, water transportation was the lifeblood of the North Carolina sounds region and the tidewater areas of Virginia. The landlocked sounds were entirely dependent upon poor overland tracks or shipment along the treacherous Carolina coast to reach further markets through Norfolk, Virginia. In May 1763, George Washington made his first visit to the Great Dismal Swamp and suggested draining it and digging a north-south canal through it to connect the waters of the Chesapeake Bay in Virginia and Albemarle Sound in North Carolina. As the first president, Washington agreed with Virginia Governor Patrick Henry that canals were the easiest answer for an efficient means of internal transportation and urged their creation and improvement. In 1784, the Dismal Swamp Canal Company was created. Work was started in 1793. The canal was dug completely by hand; most of the labor was done by slaves hired from nearby landowners. It took approximately 12 years of back-breaking construction under highly unfavorable conditions to complete the 22-mile long waterway, which opened in 1805. At about the time the canal opened, the Dismal Swamp Hotel was built astride the state line on the west bank. It was a popular spot for lover's trysts as well as duels; the winner was rarely arrested as the dead man, as well as the crime, were in another state. As the state line split the main salon, the hotel was quite popular with gamblers who would simply move the game to the opposite side of the room with the arrival of the sheriff from the other jurisdiction. No trace of the hotel can be found today. Tolls were charged for maintenance and improvements. In 1829, the channel was deepened. The waterway was an important route of commerce in the era before railroads and highways became major transportation modes.

American Civil War

During the American Civil War (1861-1865) the canal was in an important strategic position for Union and Confederate forces. In April, 1862, upon learning of rumors that the canal would be used to help the Confederate ironclad escape from Hampton Roads to the Albemarle Sound in North Carolina, Union General Ambrose E. Burnside sent General Jesse L. Reno from Roanoke Island to destroy the Culpepper Locks near South Mills on the Dismal Swamp Canal. Reno's 3,000 troops disembarked from their transports near Elizabeth City on April 18. The Union troops advanced the following morning on an exhausting march toward South Mills where Confederate Colonel Ambrose R. Wright posted his 900 men to command the road to the town. Reno encountered Wright's position at noon. The Confederates' determined fighting continued for four hours until their artillery commander, Captain W. W. McComas, was killed. To avoid being flanked, Wright retired behind Joy's Creek, two miles away. General Reno did not pursue them because of his losses and his troops' exhaustion. That evening he heard a rumor that Confederate reinforcements were arriving from Norfolk and ordered a silent march back to the transports near Elizabeth City. The losses were estimated at 114 Union and 25 Confederate soldiers. The Battle of South Mills was the only battle action near the canal. However, wartime activity left the canal in a terrible state of repair. The repairs and maintenance needed by the canal made travel difficult.

Post-war, 20th century

In 1892, Lake Drummond Canal and Water Company launched rehabilitation efforts and once again, a steady stream of vessels carrying lumber, shingles, farm products, and passengers made the canal a bustling interstate thoroughfare. By the 1920s, improvements in other modes of transportation meant another downturn for the canal, and commercial traffic had subsided except for passenger vessels. In 1929 it was sold to the federal government for $500,000. As recreational boating became popular in the mid-20th century, the canal became an important link to provide shelter from the brutal forces to the treacherous Atlantic Coast line off the Carolinas and the Virginia capes.

Current use

In modern times, the U.S. Army Corps of Engineers operates and maintains the canal. About 2,000 recreational boaters travel the canal each year as they pass along the Atlantic Intracoastal Waterway, an inland route which offers sheltered passage from the Atlantic Ocean from Boston, Massachusetts to Key West, Florida. The Virginia portion of the canal was located in Norfolk County, which today is the City of Chesapeake, where the northern portion of the canal at Deep Creek connects with the Southern Branch of the Elizabeth River. The southern end of the canal lead to Albemarle Sound. The Dismal Swamp Canal Visitor Center is the only Visitor Center in the continental U. S. greeting visitors by both a major highway and an historic waterway. It is located in Camden County, North Carolina on scenic U.S. Highway 17 three miles south of the Virginia/North Carolina border. The Canal is listed in the National Register of Historic Places and has been designated a National Civil Engineering Landmark. The historic canal is now recognized as part of the National Underground Railroad and along with the Great Dismal Swamp, is noted as a former sanctuary for runaway slaves seeking freedom.

Great Dismal Swamp

in the United States on the coast of the Atlantic Ocean.]] The Great Dismal Swamp is a marshy region on the Coastal Plain of southeastern Virginia and northeastern North Carolina between Norfolk, Virginia, and Elizabeth City, North Carolina in the United States. It is a southern swamp, the northernmost of many along the Atlantic Ocean's coast which includes the Everglades and the Big Cypress Swamp in Florida, the Okefenokee Swamp in Georgia, the Congaree Swamp and Four Holes swamps of South Carolina, and some of the Carolina bays in the Carolinas. Along the eastern edge runs the Dismal Swamp Canal, completed in 1805. Essential to the swamp ecosystem are its water resources, native vegetative communities, and varied wildlife species. The Great Dismal Swamp's ecological significance and its wealth of history and lore make it a unique wilderness. It is one of the last large and wild areas remaining in the Eastern United States. After centuries of logging and other human activities which were devastating the swamp's ecosystems, the Great Dismal Swamp National Wildlife Refuge was created in 1973 when the Union Camp Corporation of Franklin, Virginia donated 49,100 acres (200 km²) of land; the refuge was officially established through The Dismal Swamp Act of 1974. The refuge consists of over 111,000 acres (500 km²) of forested wetlands. Lake Drummond, a 3,100 acre (13 km²) natural lake, is located in the heart of the swamp. Outside the boundaries of the National Refuge, the state of North Carolina has preserved and protected additional portions of the swamp.

History

Scientists believe the Great Dismal Swamp was created when the Continental shelf made its last big shift. The whole swamp has peat underneath. The origin of Lake Drummond, one of only two natural lakes in Virginia, is in argument. Scientists believe the lake could have been created by the impact of a meteorite because it is oval shaped, looking like the impact of a meteor. They think it was made by a big meteorite like the ones that are thought to have made the Carolina Bays. Other people believe it was made by a large underground peat burn about 3,500 to 6,000 years ago. Indian legend talks about "the fire bird" creating Lake Drummond. People are not sure who discovered the Great Dismal Swamp but there is archeological evidence which indicates human occupation began nearly 13,000 years ago. By 1650, few Native Americans remained in the area, and European settlers showed little interest in the swamp. In 1665, William Drummond, a future governor of North Carolina, was the first European to explore the lake which now bears his name. William Byrd II led a surveying party into the swamp to draw a dividing line between Virginia and North Carolina in 1728. Twenty-six years before George Washington became the first president of the United States, he first visited the swamp and then formed the Dismal Swamp Land Company in 1763, which proceeded to drain and log off part of the area. A five-mile ditch on the west side of the current refuge there still bears his name. In 1805, the Dismal Swamp Canal began serving as a commercial highway for timber coming out of the swamp. Dismal Swamp Canal Before and during the American Civil War, the Great Dismal Swamp was a hideout for runaway slaves from the surrounding area. Some people believe there were at least a thousand slaves living in the swamp. This was the subject of Dred: A Tale of the Great Dismal Swamp, Harriet Beecher Stowe's follow-on to Uncle Tom's Cabin. While all efforts to drain the swamp ultimately failed, logging of the swamp proved to be a successful commercial activity. Regular logging operations continued as late as 1976. The entire swamp has been logged at least once, and many areas have been burned by periodic wildfires. The Great Dismal Swamp has been drastically altered by humans over the past two centuries. Agricultural, commercial, and residential development destroyed much of the swamp, so that the remaining portion within and around the refuge represents less than half of the original size of the swamp. Before the refuge was established, over 140 miles of roads were constructed to provide access to the timber. These roads severely disrupted the swamp's natural hydrology, as the ditches which were dug to provide soil for the road beds drained water from the swamp. The roads also blocked the flow of water across the swamp's surface, flooding some areas of the swamp with stagnant water. The logging operations removed natural stands of baldcypress and Atlantic white cypress that were replaced by other forest types, particularly red maple. A drier swamp and the suppression of wildfires, which once cleared the land for seed germination, created environmental conditions that were less favorable to the survival of cypress stands. As a result, plant and animal diversity decreased.

Preservation

In the mid 20th century, conservation groups from all over America began demanding that something be done to preserve what was left of the Great Dismal Swamp. In 1973, the Union Camp Company, a paper company based in Franklin, Virginia which had had large land property in the area since the beginning of this century, donated just over 49,000 acres (198 km²) of its land to The Nature Conservancy, which transferred the property the following year to the U.S. Fish and Wildlife Service. The Great Dismal Swamp National Wildlife Refuge was officially established by the U.S. Congress through The Dismal Swamp Act of 1974. The refuge consists of almost 107,000 acres (433 km²) of forested wetlands. The primary purpose of the refuge's resource management programs is to restore and maintain the natural biological diversity that existed prior to the human-caused alterations. Essential to the swamp ecosystem are its water resources, native vegetation communities, and varied wildlife species. Water is being conserved and managed by placing water control structures in the ditches. Plant community diversity is being restored and maintained through forest management activities which simulate the ecological effects of wildfires. Wildlife is managed by insuring the presence of required habitats, with hunting used to balance some wildlife populations with available food supplies.

Today

The Great Dismal Swamp National Wildlife Refuge is located not only between two states, but also between two eco-regions, allowing for a wide range of plant and animal species. Baldcypress, tupelo, maple, Atlantic white cypress, and pine are the predominant tree species found on the refuge and support the wildlife within. Many mammal species, including black bear, bobcat, otter, and weasel along with over 70 species of reptiles and amphibians call the swamp home. More than 200 bird species can be seen at the swamp throughout the year, while 96 of those are known to nest on the refuge. Lake Drummond is the middle of activity in the swamp today, though, with many fishermen, sightseers, and boaters. Boat tours are given from the Dismal Swamp Canal, to Lake Drummond. The refuge is open daily during daylight hours. There is no entrance fee. The refuge headquarters, at the western edge of the refuge, is open on weekdays, except national holidays. Visitor activities include birdwatching, photography, hiking, bicycling, boating and canoing (a boat-launching ramp, offering access to Lake Drummond, is provided onto the Feeder Ditch, at the eastern edge of the refuge), fishing, and deer hunting on parts of the refuge during the designated season. Although camping is not permitted on the refuge, campground facilities are available in the general vicinity. Hiking opportunities include the nearly 0.75-mile (wheelchair-accessible) Dismal Town Boardwalk Trail, located on Washington Ditch Road, that winds through part of the swamp habitat; and a number of the refuge's unpaved roads that are also open to bicycling. The peak influx of neotropical migratory songbirds, such as numerous species of warblers, is from late April to mid-May. The Dismal Swamp Canal canal continues to serve recreational boaters as part of the Atlantic Intracoastal Waterway, administered by the United States Army Corps of Engineers.

Virginia

The Commonwealth of Virginia is one of the original thirteen states of the United States that revolted against British rule in the American Revolution, and is part of the South. It is one of four states that use the name commonwealth. Virginia was the first part of the Americas to be colonized permanently by England. Virginia's U.S. postal abbreviation is VA, and its Associated Press abbreviation is Va. Kentucky and West Virginia were part of Virginia at the time of the founding of the United States; but the former was admitted to the Union as a separate state in 1792, while the latter broke away from Virginia during the American Civil War. Virginia is known as the "Mother of Presidents", because it is the birthplace of eight U.S. presidents, more than any other state. Five of them were re-elected to a second term: George Washington, Thomas Jefferson, James Madison, James Monroe and Woodrow Wilson. William Henry Harrison, John Tyler, and Zachary Taylor round out the list of American Presidents from the Commonwealth of Virginia. (Harrison and Taylor died while in office.)

History

Native Americans

At the time of the English colonization of Virginia, among Native American people living in what now is Virginia were the Cherokee, Chickahominy, Mattaponi, Meherrin, Monacan, Nansemond, Nottaway, Pamunkey, Pohick, Powhatan, Rappahannock, Saponi, and Tuscarora. The natives are often divided into three groups. The largest group are known as the Algonquian who numbered over 10,000. The other groups are the Iroquoian (numbering 2,500) and the Siouan.

Virginia Colony: 1607–1776

At the end of the 16th century, when Great Britain began to colonize North America, Virginia was the name that Queen Elizabeth I of England (who was known as the "Virgin Queen" because she never married) gave to the whole area explored by the 1584 expedition of Sir Walter Raleigh along the coast of North America, eventually applying to the whole coast from South Carolina to Maine. The London Virginia Company became incorporated as a joint stock company by a proprietary charter drawn up on April 10, 1606. It swiftly financed the first permanent English settlement in the New World, which was at Jamestown, named in honor of King James I, in the Virginia Colony, in 1607, which settlement was founded by Captian Christopher Newport and Captain John Smith. Its Second Charter was officially ratified on May 23, 1609. Jamestown was the original capital of the Virginia Colony, and remained so until the State House burned (not the first time) in 1698. After the fire, the colonial capital was moved to nearby Middle Plantation, which was renamed Williamsburg in honor of William of Orange, King William III. Virginia was given its nickname, "The Old Dominion", by King Charles II of England at the time of the Restoration, because it had remained loyal to the crown during the English Civil War.

A new state

In 1780, during the American Revolutionary War, the capital was moved to Richmond at the urging of then-Governor Thomas Jefferson, who was afraid that Williamsburg's location made it vulnerable to a British attack. In the autumn of 1781, American troops trapped the British on the Yorktown peninsula in the famous Battle of Yorktown. This prompted a British surrender on October 19, 1781, formally ending the war and securing the former colonies' independence, even though sporadic fighting continued for two years. Patrick Henry served as the first Governor of Virginia, from 1776 to 1779, and again from 1784 to 1786. On June 12, 1776, the Virginia Convention adopted the Virginia Declaration of Rights, a document that influenced the Bill of Rights added later to the United States Constitution. On June 29, 1776, the convention adopted a constitution that established Virginia as a commonwealth independent of the British Empire. In 1790 both Virginia and Maryland ceded territory to form the new District of Columbia, but in an Act of the U.S. Congress dated July 9, 1846, the area south of the Potomac that had been ceded by Virginia was retroceded to Virginia effective 1847, and is now Arlington County and part of the City of Alexandria.

American Civil War

Virginia is one of the states that seceded from the Union to become the Confederacy during the Civil War. When it did, some counties were separated as Kanawha (later renamed West Virginia), an act which was upheld by the United States Supreme Court in 1870. More battles were fought on Virginia soil than anywhere else in America during the Civil War. Virginia formally rejoined the Union on January 26, 1870, after a period of post-war military rule.

20th century

When Douglas Wilder was elected Governor of Virginia on January 13, 1990, he became the first African-American to serve as Governor of a U.S. state since Reconstruction.

Law and government

The capital is Richmond: the current Governor is Mark Warner, a Democrat. Tim Kaine, also a Democrat, is the governor-elect. Previous capitals included Jamestown (1609–1699) and Williamsburg (1699–1780). The Virginia State Capitol building in Richmond was designed by Thomas Jefferson and the cornerstone was laid by Governor Patrick Henry in 1785. In colonial Virginia, the lower house of the legislature was called the House of Burgesses. Together with the Governor's Council, the House of Burgesses made up the General Assembly. The Governor's Council was composed of 12 men appointed by the British Monarch to advise the Governor. The Council also served as the General Court of the colony, a colonial equivalent of a Supreme Court. Members of the House of Burgesses were chosen by all those who could vote in the colony. Each county chose two people or burgesses to represent it, while the College of William and Mary and the cities of Norfolk, Williamsburg, and Jamestown each chose one burgess. The Burgesses met to make laws for the colony and set the direction for its future growth; the Council would then review the laws and either approve or disapprove them. The approval of the Burgesses, the Council, and the Governor was needed to pass a law. The idea of electing burgesses was important and new. It gave Virginians a chance to control their own government for the first time. At first the burgesses were elected by all free men in the colony. Women, indentured servants, and Native Americans could not vote. Later the rules for voting changed, making it necessary for men to own at least fifty acres (200,000 m²) of land in order to vote. Founded in 1619, the Virginia General Assembly is still in existence as the oldest legislature in the Western Hemisphere. Today, the General Assembly is made up of the Senate and the House of Delegates. Like many other states, by the 1850s Virginia featured a state legislature, several executive officers, and an independent judiciary. By the time of the Constitution of 1901, which lasted longer than any other state constitution, the General Assembly continued as the legislature, the Supreme Court of Appeals acted as the judiciary, and the eight elected executive officers were the Governor, Lieutenant Governor, Attorney General, Secretary of the Commonwealth, State Treasurer, Auditor of Public Accounts, Superintendent of Public Instruction and Commissioner of Agriculture and Immigration. The Constitution of 1901 was amended many times, notably in the 1930s and 1950s, before it was abandoned in favour of more modern government, with fewer elected officials, reformed local governments and a more streamlined judiciary. Virginia currently functions under the 1970 Constitution of Virginia. It is the state's ninth constitution. Under the Constitution, the State Government is composed of three branches: legislative, executive, and judicial. The legislative branch or state legislature is the Virginia General Assembly, a bicameral body whose 140 members make all state laws. Members of the Virginia House of Delegates serve two-year terms, while members of the Virginia Senate serve four-year terms. The General Assembly also selects the state's Auditor of Public Accounts. The statutory law enacted by the General Assembly is codified in the Code of Virginia. The executive branch comprises the Governor of Virginia, the Lieutenant Governor of Virginia, and the Attorney General of Virginia. All three officers are separately elected to four-year terms in years following Presidential elections (1997, 2001, 2005, etc) and take office in January of the following year. The Governor serves as chief executive officer of the Commonwealth and as Commander-in-Chief of the State Militia. State law forbids any Governor from serving consecutive terms. The Lieutenant Governor serves as President of the Senate of Virginia and is first in the line of succession to the Governor. The Attorney General is chief legal advisor to the Governor and the General Assembly, chief lawyer of the state and the head of the Department of Law. The Attorney General is second in the line of succession to the Governor. Whenever there is a vacancy in all three executive offices of Governor, Lieutenant Governor, and Attorney General, then the Speaker of the House of the Virginia House of Delegates becomes Governor. The Office of the Governor's Secretaries helps manage the Governor's Cabinet, comprised of the following individuals, all appointed by the Governor:
- Governor's Chief of Staff
- Secretary of Administration
- Secretary of Agriculture and Forestry
- Secretary of Commerce and Trade
- Secretary of the Commonwealth
- Secretary of Education
- Secretary of Finance
- Secretary of Health and Human Resources
- Secretary of Natural Resources
- Secretary of Public Safety
- Secretary of Technology
- Secretary of Transportation
- Assistant to the Governor for Commonwealth Preparedness The judicial branch consists of the Supreme Court of Virginia, the Virginia Court of Appeals, the General District Courts and the Circuit Courts. The Virginia Supreme Court, composed of the chief justice and six other judges is the highest court in the Commonwealth (although, as with all the states, the U.S. Supreme Court has appellate jurisdiction over decisions by the Virginia Supreme Court involving substantial questions of U.S. Constitution law or constitutional rights). The Chief Justice and the Virginia Supreme Court also serve as the administrative body for the entire Virginia court system. The 95 counties and the 39 independent cities all have their own governments, usually a county board of supervisors or city council which choose a city manager or county administrator to serve as a professional, non-political chief administrator under the council-manager form of government. There are exceptions, notably Richmond, Virginia, which has a popularly-elected Mayor who serves as chief executive separate from the city council.

Political control

After William Mahone and the Readjuster Party lost control of Virginia politics around 1883, the Democratic Party held a strong majority position of state and federal offices for over 85 years. In 1970, Republican A. Linwood Holton Jr. became the first Republican governor in the 20th century. In the years thereafter, Republicans made substantial gains, and for a time, controlled both houses of the Virginia General Assembly, as well as the Governorship from 1994 until 2002.
- Republicans hold both seats in the U.S. Senate, 8 of 11 seats in the U.S. House of Representatives, hold a majority in the Virginia House of Delegates and the Virginia Senate, and a Republican is Virginia's Lieutenant Governor-Elect. A republican is also temporarily serving as attorney general having been appointed to fill the seat left by Jerry Kilgore. However, the recent election for attorney general to fill the open seat has not been decided and a recount will occur to determine the election.
- Democrats control the remaining 3 seats in the U.S. House of Representatives. The Governor and Governor-Elect are both Democrats. The Democrats have steadily been gaining seats in the Virginia House of Delegates and may soon take control, however the State Senate will likely remain under Republican Leadership. Incumbent Virginia governors cannot run for re-election under the state constitution and In the November 2005 election, the race to succeed Democratic Governor Mark Warner, Democrat Timothy M. Kaine beat Republican Attorney General Jerry Kilgore (Scott County), and State Senator Russ Potts (Winchester) (longtime Republican) running as an independent. Kaine will become governor of the state at his inauguration on January 14, 2006.

Geography

2006 2006 Virginia is bordered by West Virginia, Maryland, and the District of Columbia (across the Potomac River) to the north, by Chesapeake Bay and the Atlantic Ocean to the east, by North Carolina and Tennessee to the south, and by Kentucky and West Virginia to the west. The Chesapeake Bay divides the state, with the eastern portion (called 'the Eastern Shore of Virginia'), a part of the Delmarva Peninsula, completely separate (an exclave) from the rest of the state. Geographically, Virginia is divided into the following 5 regions:
- Tidewater - Stretching from the Atlantic coast to the fall line
- Piedmont - East of the Blue Ridge Mountains to the Tidewater Region
- Blue Ridge Mountains - East of the Appalachian Mountains to the Blue Ridge Mountain Region
- Valley and Ridge - Appalachian Mountains and Shenandoah Valley Region
- Appalachian Plateau - West of the Appalachian Mountains Virginia's long east-west axis means that metropolitan northern Virginia lies much closer to New York and New England than to the rural western panhandle of its own state. Conversely, Lee County, at the tip of the panhandle, is closer to 8 state capitals than it is to Richmond.

Demographics

As of 2004, Virginia's population was estimated to be 7,459,827. The state had a foreign-born population of 679,500 (9.1% of the state population), of which an estimated 100,000 were illegal aliens (15% of the foreign-born). The state's population increased by 1.3 million between 1990 and 2004, a growth of 21% Race and Ancestry
The racial makeup of the state:
- 70.2% White non-Hispanic
- 19.6% Black
- 4.7% Hispanic
- 3.7% Asian
- 0.3% Native American
- 2% Mixed race The five largest reported ancestry groups in Virginia are: African American (19.6%), German (11.7%), American (11.2%), English (11.1%), Irish (9.8%). Historically, as the largest and wealthiest colony and state and the birthplace of Southern and American culture, a large proportion (about half) of Virginia's population was made up of black slaves who worked the state's tobacco, cotton, and hemp plantations. The twentieth century Great Migration of blacks from the rural South to the urban North reduced Virginia's black population to about 20 percent. Today Blacks are concentrated in the eastern and southern tidewater and piedmont regions where plantation agriculture was most dominant. The western mountains are populated primarily by people of British and American ancestry. People of German descent are present in sizable numbers in the northwestern mountains and Shenandoah Valley. And due to recent immigration, there is a rapidly growing population of Hispanics (particularly Central Americans) and Asians in the northern Virginia suburbs of Washington, DC. 6.5% of Virginia's population were reported as under 5, 24.6% under 18, and 11.2% were 65 or older. Females made up approximately 51% of the population.

Religion

The religious affiliations of the people of Virginia are:
- Christian – 84%
  - Protestant – 69%
    - Baptist – 32%
    - Methodist – 8%
    - Episcopal – 3%
