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.

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.

  • 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.
  • Mangroves.
  • Salt marsh plants.
  • Salt meadows.
  • Cordgrass.

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?
