Atlantic Intracoastal Waterway in the context of Hobucken, North Carolina

Barnegat Bay is a small brackish arm of the Atlantic Ocean, approximately 42 miles (68 km) long, along the coast of Ocean County, New Jersey in the United States. It is separated from the Atlantic by the long Island Beach State Park (colloquially called a "barrier island"), as well as by the north end of Long Beach Island, popular segments of the Jersey Shore. The bay is fed by several small rivers, including the Toms River, the Forked River, the Metedeconk River, Cedar Creek, Oyster Creek, Mill Creek, Westecunk Creek, and Tuckerton Creek, all of which empty into the bay through small estuaries along its inner shore. The communities of Toms River, Silverton, and Forked River sit along the river estuaries on the bay.

The bay connects with the ocean through the Barnegat Inlet, along which sits the Barnegat Lighthouse. The bay is part of the Atlantic Intracoastal Waterway, entered on its north end by the Point Pleasant Canal and connecting on the south end with Little Egg Harbor via the small Manahawkin Bay. In a broader sense, Barnegat Bay is sometimes considered to stretch to the south end of Long Beach Island and to include Little Egg Harbor.

Cape Fear is a coastal plain and Tidewater region of North Carolina centered about the city of Wilmington. The region takes its name from the adjacent Cape Fear headland, as does the Cape Fear River which flows through the region and empties into the Atlantic Ocean near the cape. The region's populated areas are mainly found along the Atlantic beaches and the Atlantic Intracoastal Waterway, while the rural areas are dominated by farms and swampland like that of the Green Swamp. The general area can be also identified by the titles "Lower Cape Fear", "Wilmington, NC Metropolitan Statistical Area", "Southeastern North Carolina", and "Azalea Coast". The latter name is derived from the North Carolina Azalea Festival held annually in Wilmington. Municipalities in the area belong to the Cape Fear Council of Governments.

The region is home to the Port of Wilmington, the busiest port in North Carolina, operated by the North Carolina State Ports Authority. It is also the location of Military Ocean Terminal Sunny Point, the largest ammunition port in the nation, and the U.S. Army's primary East Coast deep-water port.

The Elizabeth River is a 6-mile-long (10 km) tidal estuary forming an arm of Hampton Roads harbor at the southern end of Chesapeake Bay in southeast Virginia in the United States. It is located along the southern side of the mouth of the James River, between the cities of Portsmouth, Norfolk, and Chesapeake. Forming the core of the Hampton Roads harbor, it is heavily supported by its tributaries which depend upon it.

Through its Southern Branch and the Albemarle and Chesapeake Canal, the Elizabeth River also is a gateway to points to the south for the Atlantic Intracoastal Waterway, an inland path from the ocean providing a more sheltered navigable waterway to Florida for commercial and recreational boating.
