24-471: The park around the lagoon was created in 1940 to protect the lagoon and particularly the population of black-necked swans ( Cygnus melancoryphus ). It has an area of 112.5 km². The lagoon is situated in the Patagonian steppe , surrounded by hills and gorges. It has important aquatic bird fauna, of several species and in great number. The lagoon used to host the largest known subpopulation of

48-539: A lake is hu ( 湖 ), and a lagoon is xihu ( 潟湖 ). In the French Mediterranean several lagoons are called étang ("lake"). Contrariwise, several other languages have specific words for such bodies of water. In Spanish, coastal lagoons generically are laguna costera , but those on the Mediterranean coast are specifically called albufera . In Russian and Ukrainian, those on

72-422: A regular flow of fresh water an "estuary". Davis does state that the terms "lagoon" and "estuary" are "often loosely applied, even in scientific literature". Timothy M. Kusky characterizes lagoons as normally being elongated parallel to the coast, while estuaries are usually drowned river valleys, elongated perpendicular to the coast. Coastal lagoons are classified as inland bodies of water. When used within

96-458: Is actually the third-largest lake by area in the country. The brackish water lagoon may be thus explicitly identified as a "coastal lagoon" ( laguna costera ). In Portuguese, a similar usage is found: lagoa may be a body of shallow seawater, or a small freshwater lake not linked to the sea. Lagoon is derived from the Italian laguna , which refers to the waters around Venice ,

120-754: Is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries . Lagoons are common coastal features around many parts of the world. Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal , coral reef , or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity . The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restricts "lagoon" to bodies of water with little or no fresh water inflow, and little or no tidal flow, and calls any bay that receives

144-492: Is low, averaging between 150 and 200 mm (5.9 and 7.9 in) per year, most of it concentrated in winter. Lagoon A lagoon is a shallow body of water separated from a larger body of water by a narrow landform , such as reefs , barrier islands , barrier peninsulas, or isthmuses . Lagoons are commonly divided into coastal lagoons (or barrier lagoons ) and atoll lagoons . They have also been identified as occurring on mixed-sand and gravel coastlines. There

168-626: The Black Sea are liman ( лиман ), while the generic word is laguna ( Лагуна ). Similarly, in the Baltic , Danish has the specific Nor  [ da ] , and German the specifics Bodden and Haff , as well as generic terms derived from laguna . In Poland these lagoons are called zalew ("bay"), in Lithuania marios ("lagoon, reservoir"). In Jutland several lagoons are known as fjord . In New Zealand

192-523: The Māori word hapua refers to a coastal lagoon formed at the mouth of a braided river where there are mixed sand and gravel beaches, while waituna , an ephemeral coastal waterbody, is neither a true lagoon, lake nor estuary. Some languages differentiate between coastal and atoll lagoons. In French, lagon  [ fr ] refers specifically to an atoll lagoon, while coastal lagoons are described as étang  [ fr ] ,

216-474: The Scottish Wildlife Trust as a Wildlife Reserve, as well as being designated as a Local Nature Reserve , Site of Special Scientific Interest , a Special Protection Area and a Ramsar Site . The enclosed tidal basin has a variety of habitats within it from exposed tidal mudflats to saltmarsh , reedbed and fen and its surroundings of arable farmland and pasture. The section of

240-610: The Venetian Lagoon . Laguna is attested in English by at least 1612, and had been Anglicized to "lagune" by 1673. In 1697 William Dampier referred to a "Lagune or Lake of Salt water" on the coast of Mexico. Captain James Cook described an island "of Oval form with a Lagoon in the middle" in 1769. Atoll lagoons form as coral reefs grow upwards while the islands that the reefs surround subside, until eventually only

264-458: The Wadden Sea , have strong tidal currents and mixing. Coastal lagoons tend to accumulate sediments from inflowing rivers, from runoff from the shores of the lagoon, and from sediment carried into the lagoon through inlets by the tide. Large quantities of sediment may be occasionally be deposited in a lagoon when storm waves overwash barrier islands. Mangroves and marsh plants can facilitate

288-466: The endemic Patagonia frog ( Atelognathus patagonicus ), but this has been extirpated by introduced predatory fish; the species survives in isolated ponds in the buffer zone of the national park. Near the lagoon is the Salamanca cave, historically inhabited by humans, where rock paintings, typical of northern Patagonia, can be seen. Other mapuche and prehistoric human artifacts have been found in

312-581: The accumulation of sediment in a lagoon. Benthic organisms may stabilize or destabilize sediments. Montrose Basin Montrose Basin is a nearly circular tidal basin which makes up part of the estuary of the River South Esk and which sits just inland of the town of Montrose in Angus on the east coast of Scotland. The basin is protected by a number of designations; it is managed by

336-849: The basin at Maryton is an important site for the study of the sea level fluctuations following the end of the last glaciation. The SPA includes the small, eutrophic freshwater loch called Dun's Dish . The basin contains the largest area of saltmarsh in Angus. The extensive mudflats are home to large populations of invertebrates, especially annelid worms, the snail Hydrobia and the amphipod Corophium . There are also beds of mussels Mytilus edulis . The flora includes beds consisting of three species of eel grass , Zostera , and algae. The mudflats support numbers of waders and wildfowl including Eurasian oystercatcher , common redshank , red knot , mute swan , Eurasian wigeon and common eider . Large flocks of pink-footed goose and greylag goose use

360-592: The basin to roost in and feed in the surrounding farmland. As well as wintering eiders the basin supports a large breeding population. In all 213 species of bird have been recorded on the basin, most being winter visitors or passage migrants and just over 50 species are thought to breed. A visitor centre was opened on the south side of the basin at Rossie Braes by the Scottish Wildlife Trust in 1995. The Montrose Basin Heritage Society

384-626: The context of a distinctive portion of coral reef ecosystems, the term "lagoon" is synonymous with the term "back reef" or "backreef", which is more commonly used by coral reef scientists to refer to the same area. Many lagoons do not include "lagoon" in their common names. Currituck , Albemarle and Pamlico Sounds in North Carolina , Great South Bay between Long Island and the barrier beaches of Fire Island in New York , Isle of Wight Bay , which separates Ocean City, Maryland from

408-597: The generic word for a still lake or pond. In Vietnamese, Đầm san hô refers to an atoll lagoon, whilst Đầm phá is coastal. In Latin America, the term laguna in Spanish, which lagoon translates to, may be used for a small fresh water lake in a similar way a creek is considered a small river. However, sometimes it is popularly used to describe a full-sized lake , such as Laguna Catemaco in Mexico, which

432-630: The lagoon. Lagoons with little or no interchange with the open ocean, little or no inflow of fresh water, and high evaporation rates, such as Lake St. Lucia , in South Africa , may become highly saline. Lagoons with no connection to the open ocean and significant inflow of fresh water, such as the Lake Worth Lagoon in Florida in the middle of the 19th century, may be entirely fresh. On the other hand, lagoons with many wide inlets, such as

456-556: The land along the coast). Coastal lagoons do not form along steep or rocky coasts, or if the range of tides is more than 4 metres (13 ft). Due to the gentle slope of the coast, coastal lagoons are shallow. A relative drop in sea level may leave a lagoon largely dry, while a rise in sea level may let the sea breach or destroy barrier islands, and leave reefs too deep underwater to protect the lagoon. Coastal lagoons are young and dynamic, and may be short-lived in geological terms. Coastal lagoons are common, occurring along nearly 15 percent of

480-406: The park. The park has an arid and windy climate with a large diurnal range . During summer, the mean temperature is 22 °C (71.6 °F) with temperatures that can exceed 40 °C (104.0 °F) during heat waves . In winter, the mean temperature is 5 °C (41.0 °F) with minimum temperatures reaching −20 °C (−4.0 °F). Snowfall can occur during the winter months. Rainfall

504-407: The reefs remain above sea level. Unlike the lagoons that form shoreward of fringing reefs, atoll lagoons often contain some deep (>20 m (66 ft)) portions. Coastal lagoons form along gently sloping coasts where barrier islands or reefs can develop offshore, and the sea-level is rising relative to the land along the shore (either because of an intrinsic rise in sea-level, or subsidence of

528-627: The rest of Worcester County, Maryland , Banana River in Florida , US, Lake Illawarra in New South Wales , Australia, Montrose Basin in Scotland , and Broad Water in Wales have all been classified as lagoons, despite their names. In England, The Fleet at Chesil Beach has also been described as a lagoon. In some languages the word for a lagoon is simply a type of lake: In Chinese

552-522: The world's shorelines. In the United States, lagoons are found along more than 75 percent of the Eastern and Gulf Coasts . Coastal lagoons can be classified as leaky, restricted, or choked. Coastal lagoons are usually connected to the open ocean by inlets between barrier islands. The number and size of the inlets, precipitation, evaporation, and inflow of fresh water all affect the nature of

576-508: Was formed in 1999 to bring together information about the basin, including its history and archaeology. The oldest evidence for humans in the area dating back as far as over 3,000 BCE , this being the linear monument, known as the cursus, which runs from Powis to Old Montrose. The Basin has been exploited for its seafood, especially the Atlantic salmon but commercial fisheries for this species ended in 2018; and mussel cultivation gave it
