- 9.1: Estuaries
- Estuaries are coastal bodies of water have mixed fresh and salty water. The water in estuaries is mixed because they are fed by rivers but also connection with oceans. 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. Because of this connection with the sea, estuaries are strongly influenced by tides.
