Estuary Ecosystem. Cold water from dams and warm water from power stations are types of thermal pollution that affect water ways. One critical step to this goal is a shift from individual problems to a focus on maintaining ecosystem functions that benefit humans. The estuary is an ecosystem a group of living and non-living things interacting with each other. Many animals rely on estuaries for food places to breed and migration stopovers.
In the past several attempts at subdividing Neva Estuary have been undertaken by researchers. - Litter on our beaches and floating in the salt and fresh water pollutes estuaries. The waters are rich in nutrients such as plankton and bacteria. Neva Estuary is located in the eastern part of the Gulf of Finland. The calm waters provide a safe area for small fish shellfish migrating birds and shore animals. The western boundary of this estuary is not clearly defined geographically due to the lack of a comprehensive definition of an estuary in general Elliott and McLusky 2002.
The seawater entering the estuary is diluted by the fresh water flowing from rivers and streams.
Estuaries are areas of water and shoreline where rivers meet the ocean or another large body of water such as one of the Great Lakes. Cold water from dams and warm water from power stations are types of thermal pollution that affect water ways. Congress created the National Estuarine Research Reserve System to protect more than one million acres of estuarine land and water. The pattern of dilution varies between different estuaries and depends on the volume of freshwater the tidal.
