Atlantic coast of the United States is the eastern shoreline of the continental United States that fronts the Atlantic Ocean. It stretches from the maritime boundary with Canada near Maine southward to the boundary with the Gulf of Mexico at Florida. The coast contains diverse landscapes including rocky headlands, sandy beaches, barrier islands, estuaries, and major urban ports that have shaped regional culture, commerce, and ecology.
Geography and coastal features
The coast includes the Gulf of Maine, the Massachusetts Bay, the Long Island Sound, the New York Harbor, the Delaware Bay, the Chesapeake Bay, the Cape Hatteras, the Outer Banks, the Wilmington shoreline, the Port Royal Sound, the Savannah River estuary, and the St. Johns River delta, with prominent capes such as Cape Cod, Montauk Point, Cape May, Cape Henlopen, Cape Charles, Cape Fear, Cape Lookout, Cape Canaveral, and Cape Florida. The geological provinces include the New England Uplands, the Atlantic Coastal Plain, and remnants of the Piedmont; features comprise rocky coasts around Acadia National Park, barrier islands like Fire Island, Assateague Island, and Padre Island, tidal marshes in New Jersey, and drowned river valleys forming estuaries such as Long Island, Barnegat Bay, and Tampa Bay. Major waterways intersecting the coast include the Hudson River, Delaware River, James River, York River, and the Cooper River.
Climate and oceanography
Climatic regimes range from the humid continental climate in Maine and New England to the humid subtropical climate of Georgia and Florida, influenced by the Gulf Stream and seasonal features such as nor'easters and tropical cyclones including Hurricane Sandy, Hurricane Katrina, Hurricane Irma, and Hurricane Dorian. Oceanographic processes include the northward-flowing Gulf Stream and shelf circulation on the continental shelf, with important bathymetric features like the Hudson Canyon and the Blake Plateau. Seasonal phenomena include sea surface temperature gradients that drive fisheries studied by institutions such as the Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, and the National Oceanic and Atmospheric Administration.
Ecology and habitats
The coast supports habitats like salt marshes in the Atlantic Coastal Plain, mangrove stands in Florida, tidal creeks around Cape Cod National Seashore, seagrass beds in Florida Bay, oyster reefs in the Chesapeake Bay, and longleaf pine maritime forests on the southeastern barrier islands. Key species include Atlantic cod, striped bass, oysters, blue crab, loggerhead sea turtle, green sea turtle, North Atlantic right whale, and migratory birds using Monomoy National Wildlife Refuge, Cape Hatteras National Seashore, and Chincoteague National Wildlife Refuge. Conservation and research efforts involve The Nature Conservancy, National Audubon Society, National Wildlife Federation, U.S. Fish and Wildlife Service, and state agencies in Massachusetts, New York, New Jersey, Virginia, and Florida addressing habitat restoration, fisheries management, and protected areas like Assateague Island National Seashore and Everglades National Park.
Human history and settlement
Indigenous peoples including the Wampanoag, Mi'kmaq, Lenape, Powhatan Confederacy, Guale, and Timucua inhabited coastal regions before European contact by explorers such as John Cabot, Giovanni da Verrazzano, Hernando de Soto, and Ponce de León. Colonial settlements include Roanoke Colony, Jamestown, Plymouth Colony, Providence, Charleston, Savannah, and St. Augustine tied to figures like John Smith, William Bradford, Roger Williams, James Oglethorpe, and events such as the American Revolution battles at Saratoga, Battle of Long Island, and Siege of Charleston. Maritime history includes the Atlantic slave trade, Triangular trade, War of 1812, Civil War naval actions such as the Battle of Hampton Roads, and 19th–20th century immigration through Ellis Island and industrialization centered on ports like New York City, Philadelphia, and Baltimore.
Economy, ports, and transportation
Major commercial ports include Port of New York and New Jersey, Port of Savannah, Port of Charleston, Port of Miami, Port Everglades, Port of Baltimore, Port of Virginia, and Port Newark-Elizabeth Marine Terminal supporting container shipping, cruise terminals for Carnival Corporation & plc, Royal Caribbean International, and Norwegian Cruise Line, as well as bulk terminals serving ExxonMobil, Chevron, and BP plc. Infrastructure involves the Intracoastal Waterway, the Panama Canal connection for transoceanic trade, rail links by Norfolk Southern Railway and CSX Transportation, and highways including Interstate 95. Economic sectors include commercial fisheries regulated under the Magnuson-Stevens Fishery Conservation and Management Act, tourism centered on destinations like Myrtle Beach, Key West, and Cape Cod, and energy projects such as offshore wind leases developed by Ørsted (company), Avangrid, and Equinor.
Hazards and coastal management
The coast faces hazards from hurricanes (e.g., Hurricane Maria impacts in the region), nor'easters, sea level rise linked to studies by the Intergovernmental Panel on Climate Change, coastal erosion at locales like Hatteras Island, saltwater intrusion into aquifers used by City of Miami, and storm surge events like Sandy that affected New York City and Jersey City. Management tools include beach nourishment projects in Virginia Beach and Miami Beach, dune restoration in collaboration with U.S. Army Corps of Engineers, zoning ordinances in New York and Florida, and climate adaptation initiatives by the Environmental Protection Agency, Federal Emergency Management Agency, state coastal commissions such as the Massachusetts Office of Coastal Zone Management, and university centers including Duke University Marine Lab and Rutgers University. Legal frameworks and agreements guiding responses involve the Coastal Zone Management Act and interstate compacts among Atlantic coastal states.
