For example, Chinese and Russian industrial pollution, such as phenols and heavy metals, has devastated fish stocks in the Amur River and damaged its estuary soil. [34] Estuaries tend to be naturally eutrophic because land runoff discharges nutrients into estuaries. With human activities, land run-off also now includes the many chemicals used ...
There are two types of lagoons, coastal and oceanic/atoll lagoons. [19] A coastal lagoon is, as the definition above, simply a body of water that is separated from the ocean by a barrier. An atoll lagoon is a circular coral reef or several coral islands that surround a lagoon. Atoll lagoons are often much deeper than coastal lagoons. [20]

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.
The inflow of both seawater and freshwater provide high levels of nutrients in both the water column and sediment, making estuaries among the most productive natural habitats in the world. [41] Most estuaries were formed by the flooding of river-eroded or glacially scoured valleys when sea level began to rise about 10,000-12,000 years ago. [42]
Coastal dunes on the Leschenault Peninsula. Leschenault Estuary is an estuarine lagoon that lies to the north of Bunbury, Western Australia.It had in the past met the Indian Ocean at the Leschenault Inlet, but that has been altered by harbour works for Bunbury, and the creation of The Cut north of the historical inlet location.
Hynek spotted the system of lagoons through satellite imagery in April 2022 when he was studying another lagoon in northwestern Argentina that had smaller stromatolites with microbes that use ...
False Bay, Lake St Lucia This is a list of estuaries in South Africa. The list is in order from East (border with Mozambique) to the West (border with Namibia). The South African coastline stretches for some 3000 km from Kosi Bay near the Mozambique border in the east to the Gariep (Orange) River at the Namibian border in the west. Some 300 river outlets intersect this coastline and these ...
