What is the second largest estuary in the world?
What are the 4 types of estuaries?
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.
Where are estuaries found in the world?
Estuaries are found on the coast where fresh water like a river or a bay has access to the ocean. A good example of an estuary is a salt marsh that can be found close to the coast. Another example is when a river feeds directly into the ocean. The largest estuary in the United States is the Chesapeake Bay estuary.
What is the second largest estuary in the United States?

What lives in an estuary?
Fish, shellfish, and migratory birds are just a few of the animals that can live in an estuary. The Chesapeake Bay, as one example, includes several different habitats. There are oyster reefs where oysters, mud crabs, and small fish may be found.
How are estuaries classified?
Estuaries Classified by Geologic Features. Estuaries can be described by how they were formed or by the characteristics of their circulation. This classification of estuaries is based on geologic features. Classifications include coastal plain estuaries, tectonic estuaries, bar-built estuaries, and fjords.
What are estuaries and lagoons?
Estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Lagoons are shallow bodies of water which got separated from a larger body of water by some barrier or reefs.
What are the general characteristics of an estuary?
The most important variable characteristics of estuary water are the concentration of dissolved oxygen, salinity and sediment load. There is extreme spatial variability in salinity, with a range of near zero at the tidal limit of tributary rivers to 3.4% at the estuary mouth.
What is an example of an estuary?
The Mississippi River is a particularly good example of a salt wedge estuary, since its size allows the detailed observation of the current field even in the narrow interface between the salt wedge and the freshwater layer.
Why is estuary important?
Estuaries are important natural places. They provide goods and services that are economically and ecologically indispensable. Often called nurseries of the sea (USEPA, 1993), estuaries provide vital nesting and feeding habitats for many aquatic plants and animals.
What plants live in an estuary?
Page 3. Plants of the estuary
- Harsh habitat. The estuary is a hostile environment for most plants because salt dominates.
- Seagrass. Seagrass (Zostera capricorni) is the only flowering plant in New Zealand capable of living submerged in sea water.
- Seagrass decline.
- Salt marsh plants.
- Salt meadows.
Are there sharks in the OBX sound?

What is the largest estuary in the United?
In comparison, the largest estuary of United States is the Chesapeake Bay, which has a watershed of about 64,000 square miles.
Are there any sharks in the Chesapeake Bay?
Sharks are valuable members of the Chesapeake Bay food chain, and historically, 12 species have been known to inhabit the Bay’s waters. Sandbar sharks are the most common shark species in the Chesapeake Bay!

How long is the River Ob?
Why is the Chesapeake Bay an estuary?
The Chesapeake Bay is the largest of more than 100 estuaries in the United States. About half of the Bay’s water volume comes from salt water from the Atlantic Ocean. Because of this mix of fresh and salt water, the Bay’s salinity gradually increases as you move from north to south.
What eats algae in an estuary?
Oysters and clams filter algae out of the water. But it also helps to turn algae into food that bigger animals can eat. Small animals called zooplankton, which include tiny crustaceans known as copepods, are the Bay’s grazers. They swim through the water, eating smaller organisms.
What happens in an estuary?
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Although influenced by the tides, they are protected from the full force of ocean waves, winds and storms by land forms such as barrier islands or peninsulas.
How is life in an estuary fed?
Life in the estuary. Estuaries connect land and sea. They are partly enclosed bodies of water situated at the edge of the land – a mixture of freshwater from streams and rivers and saltwater from the sea. Full of nutrients and home to resilient organisms, estuaries provide rich feeding grounds for fish and birds.
What is the difference between a lagoon and an estuary?
While estuaries are deeper and have fast and strong currents, lagoons are shallow and the flow of water is much slower. Despite its name and the fact that it does have shallow water, the Indian River Lagoon is actually an estuary.
What lives in a lagoon?
These sea grass communities provide spawning, nursery, and foraging habitat for many aquatic species, including spotted sea trout, redfish (red drum), snook, tarpon, mullet, sheepshead, pompano, seahorses, blue crabs, hermit crabs, pink shrimp, scallops, clams, marine worms, marine snails, and other crustaceans.
How deep is a lagoon?
Depths rarely exceed 60 metres (about 200 feet) and many are shallower, usually less than 20 metres (about 65 feet) deep. The lagoon of Mayotte island in the Comoro archipelago in the Indian Ocean attains a maximum depth of about 92 metres (about 300 feet), but it is generally shallower.
What animals live in the estuary?
The plants attract lots of different animals to the estuary and those animals attract other animals to the estuary. Common animals include: shore and sea birds, fish, crabs, lobsters, clams, and other shellfish, marine worms, raccoons, opossums, skunks and lots of reptiles.
Which of the following rivers makes an estuary?
The Narmada, Periyar and Tapti are the only long rivers, which flow west and make estuaries. An Estuary is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Only West following rivers of India forms Estuary.
What is a fjord estuary?
Fjords. coastal plain | bar-built | deltas | tectonic | fjords. Fjords (pronounced fee-YORDS) are typically long, narrow valleys with steep sides that are created by advancing glaciers. The glaciers leave deep channels carved into the earth with a shallow barrier, or narrow sill, near the ocean.
What are the conditions of an estuary?
The salinity of estuarine water varies from estuary to estuary, and can change from one day to the next depending on the tides, weather, or other factors (Levinton, 1995.) Estuaries are transitional areas that straddle the land and the sea, as well as freshwater and saltwater habitats.
Do alligators live in estuaries?
