Where is the estuary biome typically located?

The estuary biome is typically located where ocean biomes meet freshwater habitats. This unique environment occurs at the interface of rivers and oceans, creating a dynamic ecosystem characterized by brackish water, which is a mix of saltwater and freshwater. Estuaries serve as crucial habitats for numerous species, offering vital resources such as nursery grounds for fish and habitat for various invertebrates, birds, and other wildlife.

The mixing of fresh and saltwater not only fosters biodiversity but also supports complex food webs. Additionally, estuaries often act as natural filters, trapping pollutants and sediments from rivers before they enter the open ocean, which plays a significant role in water quality and ecosystem health. This combination of freshwater influx from rivers and tidal influences from the ocean makes estuaries some of the most productive and critical ecosystems on the planet.
