Estuary - Wikipedia Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment
Estuary | Coastal Features, Marine Life Conservation | Britannica estuary, partly enclosed coastal body of water in which river water is mixed with seawater In a general sense, the estuarine environment is defined by salinity boundaries rather than by geographic boundaries
What is an estuary? - NOAAs National Ocean Service Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of fresh water draining from the land and salty seawater
Basic Information about Estuaries - US EPA Estuaries, and their surrounding lands, are places of transition from land to sea 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

Estuaries - Oceans, Coasts Seashores (U. S. National Park Service) Estuaries are sheltered bodies of water where rivers meet the sea, nutrient-rich freshwater mixes with saltwater, and sunlight penetrates the shallow depths All of these conditions combine to create some of the most biologically-rich waters on the planet
Estuary Habitat - NOAA Fisheries Estuaries are bodies of water where rivers meet the sea They provide homes for diverse wildlife, including popular fish species They also support recreation, jobs, tourism, shipping, and more Estuaries like Kachemak Bay in Alaska provide rich habitat for coastal and marine species Credit: Alaska Shorezone
9. 1: Estuaries - Geosciences LibreTexts Estuaries are coastal bodies of water where freshwater from land sources, such as rivers, and salty seawater mix Estuaries have a barrier to the sea, similar to lagoons, that protects them from ocean energy, but, unlike lagoons, estuaries still connect with the sea
National Estuarine Research Reserve System - National Oceanic and . . . Estuaries provide a safe haven and protective nursery for small fish, shellfish, migrating birds, and coastal shore animals In the U S , estuaries are nurseries to more than 75 percent of all fish and shellfish harvested
