An 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. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone.
Severe storms, climate change, pollution, habitat alteration and rapid population growth threaten the ecological functions that have supported coastal communities throughout history. Estuaries are the connection between the ocean (or Great Lakes) and the land and humans depend on both for their very existence, so caring for both – and the ...
Collapsed Ordovician limestone bank showing coastal erosion.NW Osmussaar, Estonia.. Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography (sociology and history) of the coast.
Estuaries and Coasts is a peer-reviewed scientific journal published by Springer Science+Business Media and the official journal of the Coastal and Estuarine Research Federation. It was established in 1960 as Chesapeake Science by Romeo J. Mansueti, covering research results and management studies on natural resources of the Chesapeake Bay region.
The coastal marshes, tidal creeks, and estuaries are important nursery areas for fish, crabs, shrimp, and other marine species. Charleston Harbor is one of the largest container ship ports on the East Coast, and it also contains one of the largest commercial shrimp fisheries in the state, raising concerns about the health of the estuary ...

A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Model of Estuary. The residence time of water is a key variable determining the health of an estuary, particularly from human-induced stresses.Rapid flushing ensures that there is insufficient time for sediment accumulation or dissolved oxygen depletion in the estuary; thus a well flushed estuary is intrinsically more robust than a poorly flushed estuary.
