The Cape Cod National Seashore (CCNS) encompasses 43,607 acres on Cape Cod, in Massachusetts. CCNS was created on August 7, 1961, by President John F. Kennedy, when he signed a bill enacting the legislation he first co-sponsored as a Senator a few years prior. It includes ponds, woods and beachfront of the Atlantic coastal pine barrens ecoregion. The CCNS includes nearly 40 miles (64 km) of seashore along the Atlantic-facing eastern shore of Cape Cod, in the towns of Provincetown, Truro, Wellfleet, Eastham, Orleans and Chatham. It is administered by the National Park Service.
The Wash is a rectangular bay and multiple estuary at the north-west corner of East Anglia on the East coast of England, where Norfolk meets Lincolnshire and both border the North Sea. One of Britain's broadest estuaries, it is fed by the rivers Witham, Welland, Nene and Great Ouse. It is a 620 km² biological Site of Special Scientific Interest. It is also a Nature Conservation Review site, Grade I, a National Nature Reserve, a Ramsar site, a Special Area of Conservation and a Special Protection Area. It is in the Norfolk Coast Area of Outstanding Natural Beauty and part of it is the Snettisham Royal Society for the Protection of Birds nature reserve.
A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection.
New Jersey Meadowlands, also known as the Hackensack Meadowlands after the primary river flowing through it, is a general name for a large ecosystem of wetlands in northeastern New Jersey in the United States, a few miles to the west of New York City. During the 20th century, much of the Meadowlands area was urbanized, and it became known for being the site of large landfills and decades of environmental abuse. A variety of projects are underway to restore and conserve the remaining ecological resources in the Meadowlands.
A tidal bore, often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave of water that travels up a river or narrow bay, reversing the direction of the river or bay's current. It is a strong tide that pushes up the river, against the current.
Coos Bay is an estuary where the Coos River enters the Pacific Ocean, the estuary is approximately 12 miles long and up to two miles wide. It is the largest estuary completely within Oregon state lines. The Coos Bay watershed covers an area of about 600 square miles and is located in northern Coos County, Oregon in the United States. The Coos River, which begins in the Oregon Coast Range, enters the bay from the east. From Coos River, the bay forms a sharp loop northward before arching back to the south and out to the Pacific Ocean. Haynes Inlet enters the top of this loop. South Slough branches off from the bay directly before its entrance into the Pacific Ocean. The bay was formed when sea levels rose over 20,000 years ago at the end of the Last Glacial Maximum, flooding the mouth of the Coos River. Coos Bay is Oregon's most important coastal industrial center and international shipping port, with close ties to San Francisco, the Columbia River, Puget Sound and other major ports of the Pacific rim.
The River Fal flows through Cornwall, England, United Kingdom, rising at Pentevale on Goss Moor and reaching the English Channel at Falmouth. On or near the banks of the Fal are the castles of Pendennis and St Mawes as well as Trelissick Garden. The River Fal separates the Roseland peninsula from the rest of Cornwall. Like most of its kind on the south coast of Cornwall and Devon, the Fal estuary is a classic ria, or drowned river valley. The Fal estuary from Tregony to the Truro River was originally called Hafaraell.
A tidal creek or tidal channel is a narrow inlet or estuary that is affected by the ebb and flow of ocean tides. Thus, it has variable salinity and electrical conductivity over the tidal cycle, and flushes salts from inland soils. Tidal creeks are characterized by slow water velocity, resulting in buildup of fine, organic sediment in wetlands. Creeks may often be a dry to muddy channel with little or no flow at low tide, but with significant depth of water at high tide. Due to the temporal variability of water quality parameters within the tidally influenced zone, there are unique biota associated with tidal creeks which are often specialised to such zones. Nutrients and organic matter are delivered downstream to habitats normally lacking these, while the creeks also provide access to inland habitat for salt-water organisms.
Plum Island is a barrier island located off the northeast coast of Massachusetts, north of Cape Ann, in the United States. It is approximately 11 miles (18 km) in length. The island is named for the wild beach plum shrubs that grow on its dunes, but is also famous for the purple sands at high tide, which get their color from tiny crystals of pink pyrope garnet. It is located in parts of four municipalities in Essex County. From north to south they are the city of Newburyport, and the towns of Newbury, Rowley, and Ipswich.
A tidal marsh is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. Tidal marshes experience many overlapping persistent cycles, including diurnal and semi-diurnal tides, day-night temperature fluctuations, spring-neap tides, seasonal vegetation growth and decay, upland runoff, decadal climate variations, and centennial to millennial trends in sea level and climate.
Located in northern California, the Suisun Marsh has been referred to as the largest brackish water marsh on west coast of the United States of America. The marsh land is part of the San Francisco Bay tidal estuary, and subject to tidal ebb and flood. The marsh is home to many species of birds and other wildlife, and is formed by the confluence of the Sacramento and San Joaquin rivers between Martinez and Suisun City, California and several other smaller, local watersheds. Adjacent to Suisun Bay, the marsh is immediately west of the legally defined Sacramento-San Joaquin Delta as well as part of the San Francisco Bay estuary.
The Barrington River is a tidal extension of Runnins River in the U.S. states of Rhode Island and Massachusetts. It flows approximately 6 km (4 mi). There are no dams along the river's length.
San Pablo Bay National Wildlife Refuge is a 13,190-acre (53.4 km2) National Wildlife Refuge in California established in 1970. It extends along the northern shore of San Pablo Bay, from the mouth of the Petaluma River, to Tolay Creek, Sonoma Creek, and ending at Mare Island.
The Columbia River Estuary is situated on the Oregon–Washington border and the Pacific Coast of the United States. It was traditionally inhabited by the Chinook Native Americans and discovered by settlers in 1788. The Estuary plays host to a plethora of species of marine and terrestrial flora and fauna, and multiple conservation organisations exist that maintain the area. Geologically, it is situated on a continental margin of the North American Plate.
The Sheepscot River is a 66-mile-long (106 km) river in the U.S. state of Maine. Its lower portion is a complex island estuary with connections to the Kennebec River downstream of Merrymeeting Bay.
The Herring Run is an 11.1-mile-long (17.9 km) tributary of the Back River located in Baltimore, Maryland.
Leque Island is a small island located in Snohomish County, in Washington, United States. It can be found just beneath the bridge between Camano Island and Stanwood, at the mouth of the Stillaguamish River, in Puget Sound.
East Harbor is a tidal estuary in Truro, Massachusetts that was originally a harbor until it was cut off from Cape Cod Bay to form a salt marsh lagoon, later renamed Pilgrim Lake. It is now within the Cape Cod National Seashore.
Sitka Sedge State Natural Area is an estuary and beach on the north coast of the U.S. state of Oregon in Tillamook County. Sitka Sedge consists of 357 acres (144 ha) of tidal marsh, mudflats, dunes, forested wetlands, and uplands at the south end of the Sand Lake estuary, north of Tierra Del Mar.
