Chesapeake Bay in the context of Embayment

A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action.The term embayment is also used for related features, such as extinct bays or freshwater environments.

A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some bays are large enough to have varied marine geology, such as the Bay of Bengal (2,600,000 km or 1,000,000 sq mi) and Hudson Bay (1,230,000 km or 470,000 sq mi).

The Potomac River (/pəˈtoʊmək/ ) is in the Mid-Atlantic region of the United States and flows from the Potomac Highlands in West Virginia to Chesapeake Bay in Maryland. It is 405 miles (652 km) long, with a drainage area of 14,700 square miles (38,000 km), and is the fourth-largest river along the East Coast of the United States. More than 6 million people live within its watershed.

The river forms part of the borders between Maryland and Washington, D.C., on the left descending bank, and West Virginia and Virginia on the right descending bank. Except for a small portion of its headwaters in West Virginia, the North Branch Potomac River is considered part of Maryland to the low-water mark on the opposite bank. The South Branch Potomac River lies completely within the state of West Virginia except for its headwaters, which lie in Virginia. All navigable parts of the river were designated as a National Recreation Trail in 2006, and the National Oceanic and Atmospheric Administration (NOAA) designated an 18-square-mile (47 km) portion of the river in Charles County, Maryland, as the Mallows Bay–Potomac River National Marine Sanctuary in 2019.

Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes. Hypoxia occurs when dissolved oxygen (DO) concentration falls to or below 2 mg of O₂/liter. When a body of water experiences hypoxic conditions, aquatic flora and fauna begin to change behavior in order to reach sections of water with higher oxygen levels. Once DO declines below 0.5 mg O₂/liter in a body of water, mass mortality occurs. With such a low concentration of DO, these bodies of water fail to support the aquatic life living there. Historically, many of these sites were naturally occurring. However, in the 1970s, oceanographers began noting increased instances and expanses of dead zones. These occur near inhabited coastlines, where aquatic life is most concentrated.

Coastal regions, such as the Baltic Sea, the northern Gulf of Mexico, and the Chesapeake Bay, as well as large enclosed water bodies like Lake Erie, have been affected by deoxygenation due to eutrophication. Excess nutrients are put into these systems by rivers, ultimately from urban and agricultural runoff and exacerbated by deforestation. These nutrients lead to high productivity that produces organic material that sinks to the bottom and is respired. The respiration of that organic material uses up the oxygen and causes hypoxia or anoxia.

The Southern Colonies within British America consisted of the Province of Maryland, the Colony of Virginia, the Province of Carolina (in 1712 split into North and South Carolina), and the Province of Georgia. In 1763, the newly created colonies of East Florida and West Florida were added to the Southern Colonies by Great Britain until the Spanish Empire took back Florida. These colonies were the historical core of what became the Southern United States, or "Dixie". They were located south of the Middle Colonies, although Virginia and Maryland (located on the expansive Chesapeake Bay in the Upper South) were also called the Chesapeake Colonies.

The Southern Colonies were overwhelmingly rural, with large agricultural operations, which made extensive use of slavery and indentured servitude. During a period of civil unrest, Bacon's Rebellion shaped the way that servitude and slavery worked in the South. After a series of attacks on the Susquehannock, attacks that ensued after the group of natives burnt one of Bacon's farms, Bacon's arrest, along with other arrest warrants, were issued by Governor Berkely, for attacking the natives without his permission. Bacon avoided detainment, though, and then burnt Jamestown, in response to the governor previously denying him land in fear of native attacks. Bacon hadn't believed his policies were entirely conventional, saying that they didn't ensure protection to the English settlers, as well as the exclusion of Bacon from Berkeley's social clubs and friend groups. The rebellion dissolved some time in 1676, following Charles II's initial sending of troops to restore order in the colony. This rebellion influenced the view of the Africans, helping create a completely African servitude and workforce in the Chesapeake Colonies, alleviating primarily White servitude, a working class that could be repugnant at times through disobedience and mischief. This also helped racial superiority in white regions, helping the poor and wealthy white people feel almost equal. It diminished alliances between white and black people, as had happened in Bacon's Rebellion.

Virginia, officially the Commonwealth of Virginia, is a state in the Southeastern and Mid-Atlantic regions of the United States between the Atlantic Coast and the Appalachian Mountains. The state's capital is Richmond and its most populous city is Virginia Beach. Its most populous subdivision is Fairfax County, part of Northern Virginia, where slightly over a third of Virginia's population of more than 8.8 million live.

Eastern Virginia is part of the Atlantic Plain, and the Middle Peninsula forms the mouth of the Chesapeake Bay. Central Virginia lies predominantly in the Piedmont, the foothill region of the Blue Ridge Mountains, which cross the western and southwestern parts of the state. The fertile Shenandoah Valley fosters the state's most productive agricultural counties, while the economy in Northern Virginia is driven by technology companies and U.S. federal government agencies. Hampton Roads is also the site of the region's main seaport and Naval Station Norfolk, the world's largest naval base.

The United States Naval Academy (USNA, Navy, or Annapolis) is a federal service academy in Annapolis, Maryland. It was established on 10 October 1845 during the tenure of George Bancroft as Secretary of the Navy. The Naval Academy is the second oldest of the five U.S. service academies and it educates midshipmen for service in the officer corps of the United States Navy and United States Marine Corps. It is part of the Naval University System. The 338-acre (137 ha) campus is located on the former grounds of Fort Severn at the confluence of the Severn River and Chesapeake Bay in Anne Arundel County, 33 miles (53 km) east of Washington, D.C., and 26 miles (42 km) southeast of Baltimore. The entire campus, known colloquially as the Yard, is a National Historic Landmark and home to many historic sites, buildings, and monuments. It replaced Philadelphia Naval Asylum in Philadelphia that had served as the first United States Naval Academy from 1838 to 1845, at which time the Naval Academy formed in Annapolis.

Candidates for admission generally must apply directly to the academy and apply separately for a nomination, usually from a member of Congress. Students are officers-in-training with the rank of midshipman. Tuition for midshipmen is fully funded by the Navy in exchange for an active duty service obligation upon graduation. Approximately 1,200 "plebes" (an abbreviation of the Ancient Roman word plebeian) enter the academy each summer for the rigorous Plebe Summer. About 1,000 midshipmen graduate and commission. Graduates are commissioned as either ensigns in the Navy or second lieutenants in the Marine Corps, but a small number can also be cross-commissioned as officers in other U.S. services, and the services of allied nations. The United States Naval Academy has some of the highest-paid graduates in the country according to starting salary. The academic program grants a Bachelor of Science degree with a curriculum that grades midshipmen's performance upon a broad academic program, military leadership performance, and mandatory participation in competitive athletics. Midshipmen are required to adhere to the academy's Honor Concept.

USS Missouri (hull number BB-63) is an Iowa-class battleship built for the United States Navy (USN) in the 1940s and is now a museum ship. Completed in 1944, she is the last battleship commissioned by the United States. The ship was assigned to the Pacific Theater during World War II, where she participated in the Battles of Iwo Jima and Okinawa and shelled the Japanese home islands. Her quarterdeck was the site where the Japanese Instrument of Surrender was signed, officially ending World War II.

After World War II, Missouri served in various diplomatic, show of force and training missions. In 1950, the ship ran aground during high tide in Chesapeake Bay and after great effort was re-floated several weeks later. She later fought in the Korean War during two tours between 1950 and 1953. Missouri was the first American battleship to arrive in Korean waters and served as the flagship for several admirals. The battleship took part in numerous shore bombardment operations and also served in a screening role for aircraft carriers. Missouri was decommissioned in 1955 and transferred to the reserve fleet (also known as the "Mothball Fleet").

The Roanoke Colony (/ˈroʊ.ə.noʊk/ ROH-ə-nohk) were two attempts by Sir Walter Raleigh to found the first permanent English settlement in North America. The first colony was established at Roanoke Island in 1585 as a military outpost, and was evacuated in 1586. The more famous second colony, known as the Lost Colony, began when a new group of settlers under John White arrived on the island in 1587; a relief ship in 1590 found the colony mysteriously abandoned. The fate of the 112 to 121 colonists remains unknown.

Roanoke Colony was founded by Governor Ralph Lane in 1585 on Roanoke Island in present-day Dare County, North Carolina. Poor relations with some of the local Native American tribes and a lack of supplies troubled Lane's colony. A resupply mission by Sir Richard Grenville was delayed, so Lane abandoned the colony and returned to England with Sir Francis Drake in 1586. Grenville arrived two weeks later and also returned home, leaving behind a small detachment to protect Raleigh's claim. A second expedition led by John White landed on the island in 1587. Sir Walter Raleigh had sent him to establish the "Cittie of Raleigh" on the Chesapeake Bay.

The Susquehannock, also known as the Conestoga, Minquas, and Andaste, were an Iroquoian people who lived in the lower Susquehanna River watershed in what is now Pennsylvania. Their name means “people of the muddy river.”

The Susquehannock were first described by John Smith, who explored the upper reaches of the Chesapeake Bay in 1608. The Susquehannocks were active in the fur trade and established close trading relationships with Virginia, New Sweden, and New Netherland. They were in conflict with Maryland until a treaty was negotiated in 1652, and were the target of intermittent attacks by the Haudenosaunee (Iroquois).

The Province of Maryland was an English and later British colony in North America from 1634 until 1776, when the province was one of the Thirteen Colonies that joined in supporting the American Revolution against Great Britain. In 1781, Maryland was the 13th signatory to the Articles of Confederation. The province's first settlement and capital was in St. Mary's City, located at the southern end of St. Mary's County, a peninsula in the Chesapeake Bay bordered by four tidal rivers.

The province began in 1632 as the Maryland Palatinate, a proprietary palatinate granted to Cecil Calvert, 2nd Baron Baltimore, whose father, George, had long sought to found a colony in the New World to serve as a refuge for Catholics at the time of the European wars of religion. Palatines from the Holy Roman Empire also immigrated to Maryland, with many settling in Fredrick County, with Maryland Palatines (Palatine German: Marylandisch Pälzer) reaching a population of 50,000 by 1774.

The Helen Delich Bentley Port of Baltimore is a shipping port along the tidal basins of the three branches of the Patapsco River in Baltimore, Maryland, on the upper northwest shore of the Chesapeake Bay. It is the nation's largest port facility for specialized cargo (roll-on/roll-off ships) and passenger facilities. It is operated by the Maryland Port Administration (MPA), a unit of the Maryland Department of Transportation.

Founded in 1706, the port was renamed in 2006 for Helen Delich Bentley (1923–2016), who represented Baltimore as a U.S. Representative for a decade and who had also been a maritime reporter and editor for The Baltimore Sun daily newspaper.

The Philadelphia campaign (1777–1778) was a British military campaign during the American Revolutionary War designed to gain control of Philadelphia, the Revolutionary-era capital where the Second Continental Congress convened, formed the Continental Army, and appointed George Washington as its commander in 1775, and later authored and unanimously adopted the Declaration of Independence the following year, on July 4, 1776, which formalized and escalated the war.

In the Philadelphia campaign, British General William Howe failed to draw the Continental Army under George Washington into a battle in North Jersey. Howe then embarked his army on transports, and landed them at the northern end of the Chesapeake Bay, where they began advancing north toward Philadelphia. Washington prepared defenses against Howe's movements at Brandywine Creek, but was flanked and beaten back in the Battle of Brandywine on September 11, 1777. After further skirmishes and maneuvers, Howe entered and occupied Philadelphia. Washington then unsuccessfully attacked one of Howe's garrisons at Germantown prior to retreating to Valley Forge for the winter, where he and 12,000 faced the harshest winter of the war, including insufficient food and clothing.

Fort McHenry is a historical American coastal pentagonal bastion fort on Locust Point, now a neighborhood of Baltimore, Maryland. It is best known for its role in the War of 1812, when it successfully defended Baltimore Harbor from an attack by the British navy from Chesapeake Bay on September 13–14, 1814.

The fort was built in 1798 and was used continuously by U.S. armed forces through World War I and by the United States Coast Guard in World War II. It was designated a national park in 1925, and, in 1939, was redesignated a U.S. National Monument.

Annapolis (/əˈnæpəlɪs/ ə-NAP-əl-iss) is the capital of the U.S. state of Maryland. It is the county seat of Anne Arundel County and its only incorporated city. Situated on the Chesapeake Bay at the mouth of the Severn River, 25 miles (40 km) south of Baltimore and about 30 miles (50 km) east of Washington, D.C., Annapolis forms part of the Baltimore–Washington metropolitan area. The 2020 census recorded its population as 40,812, an increase of 6.3% since 2010.

This city served as the seat of the Confederation Congress, formerly the Second Continental Congress, and temporary national capital of the United States in 1783–1784. At that time, General George Washington came before the body convened in the new Maryland State House and resigned his commission as commander of the Continental Army. A month later, the Congress ratified the Treaty of Paris of 1783, ending the American Revolutionary War, with Great Britain recognizing the independence of the United States.The city and state capitol was also the site of the 1786 Annapolis Convention, which issued a call to the states to send delegates for the Constitutional Convention to be held the following year in Philadelphia. The Annapolis Peace Conference took place in 2007.

Norfolk (locally /ˈnɔːrfək/ NOR-fək) is an independent city in the U.S. commonwealth of Virginia. It had a population of 238,005 at the 2020 census, making it the third-most populous city in Virginia and 100th-most populous city in the United States. The city holds a strategic position as the historical, urban, financial, and cultural center of the Hampton Roads metropolitan area (sometimes called "Tidewater"), which has more than 1.8 million inhabitants and is the 37th-largest metropolitan area in the U.S.

Norfolk was established in 1682 as a colonial seaport. Strategically located at the confluence of the Elizabeth River and Chesapeake Bay, it quickly developed into a major center for trade and shipbuilding. During the American Revolution and War of 1812, its port and naval facilities made it a critical military target. Norfolk's prominence grew in the 20th century with the expansion of the U.S. Navy, particularly through the establishment of Naval Station Norfolk in 1917, which remains the world's largest naval base.

Hampton Roads is a body of water in the United States that serves as a wide channel for the James, Nansemond, and Elizabeth rivers between Old Point Comfort and Sewell's Point near the point at which Chesapeake Bay flows into the Atlantic Ocean. It also gave its name to the surrounding metropolitan region located in the southeastern Virginia and northeastern North Carolina portions of the Tidewater Region.

Comprising the Virginia Beach–Norfolk–Newport News, VA–NC, metropolitan area and an extended combined statistical area that includes the Elizabeth City, North Carolina, micropolitan statistical area and Kill Devil Hills, North Carolina, micropolitan statistical area, Hampton Roads is known for its large military presence, ice-free harbor, shipyards, coal piers, and miles of waterfront property and beaches, all of which contribute to the diversity and stability of the region's economy.

The Eastern Shore of Maryland is a part of the U.S. state of Maryland that lies mostly on the east side of the Chesapeake Bay. Nine counties are normally included in the region. The Eastern Shore is part of the larger Delmarva Peninsula that Maryland shares with Delaware and Virginia.

As of the 2020 census, its population was 456,815, with about 7% of Marylanders living in the region. The region is politically more conservative than the rest of the state, generally returning more votes for Republicans than Democrats in statewide and national elections.
