What is the meaning of estuarine environment?
The estuarine environment is characterised by having a constantly changing mixture of salt and fresh water, and by being dominated by fine sedimentary material carried into the estuary from the sea and from rivers which accumulates in the estuary to form mudflats.
What does estuary mean in the dictionary?
noun, plural es·tu·ar·ies. that part of the mouth or lower course of a river in which the river’s current meets the sea’s tide. an arm or inlet of the sea at the lower end of a river.
What are the examples of estuarine?
Examples of Estuaries The Chesapeake Bay in Maryland is a large estuary. The bays surrounding the boroughs of New York City are also estuaries. San Francisco Bay in California and Lake Pontchartrain in Louisiana are other examples of large, developed estuaries.
Why do estuarine ecosystem are important?
Estuaries Are Critical Natural Habitats And many marine organisms, including most commercially-important species of fish, depend on estuaries at some point during their development. Because they are biologically productive, estuaries provide ideal areas for migratory birds to rest and refuel during their long journeys.
Why estuarine habitat is a very productive area?
Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
What are the three types of estuarine habitat?
There are four different kinds of estuaries, each created a different way: 1) coastal plain estuaries; 2) tectonic estuaries; 3) bar-built estuaries; and 4) fjord estuaries. Coastal plain estuaries (1) are created when sea levels rise and fill in an existing river valley.
Why is an estuary important?
Estuaries are important natural places. In addition to essential habitats for birds, fish, insects, and other wildlife, estuaries provide goods and services that are economically and ecologically indispensable, such as commercial fishing and recreational opportunities.
What are the characteristics of an estuarine?
In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water. Brackish water is somewhat salty, but not as salty as the ocean. An estuary may also be called a bay, lagoon, sound, or slough. Water continually circulates into and out of an estuary.
What are the ecosystem services of the estuarine ecosystems?
Estuaries provide a range of valuable ‘ecosystem services’ for humans such as food provision, water filtration, nutrient regulation and storm protection (see Figure 1).
What is the meaning of estuarine?

What is an estuary in geology?
Relating to a system of deep-water and wetland tidal habitats characterized by fluctuating salinity and, in intertidal zones, by the presence of trees, shrubs, and emergent vegetation. 3. Geology Formed or deposited in an estuary. American Heritage® Dictionary of the English Language, Fifth Edition.
What are the characteristics of estuarine ecosystems?
The physical, chemical and biological gradients typically present in estuarine ecosystems lead to a diverse and complex mosaic of habitats. Each estuary has a unique combination of features derived from its shape, catchment, connection to the sea, tidal regime and exposure.
What is the scientific name for formed or deposited in estuaries?
(Geological Science) formed or deposited in an estuary: estuarine muds. (Biology) growing in, inhabiting, or found in an estuary: an estuarine fauna.
