What is a coastal lagoon?

Coastal lagoons are bodies of water that are formed in the interface between terrestrial and marine ecosystems. These natural formations are crucial for biodiversity and play essential roles in local and global ecology. We will then explore in detail what coastal lagoons are, their distinctive characteristics, and why they are so important from an ecological point of view.

Definition and characteristics of coastal lagoons

nCoastal lagoons are saltwater or brackish bodies that are partially separated from the ocean by a natural barrier such as barrier islands, coral reefs, or sand dunes.These formations may vary in size from small pools to large bodies of water that cover several square kilometers.The connection to the ocean can be through narrow canals or entrances, which facilitates the exchange of water and nutrients between both ecosystems.nnA distinctive feature of coastal lagoons is their variability in salinity, which can change dramatically due to factors such as the entry of freshwater from rivers or intense evaporation.nnThis fluctuating environment creates a unique habitat that can withstand a diversity of organisms adapted to these changing conditions.In addition, coastal lagoons tend to have shallow water zones, which allows the penetration of sunlight to the bottom, promoting primary production through photosynthesis.nnCoastal lagoons also present a geomorphological structure that can include marshes, mangroves, grasslands of marine pastures, and areas of soft sediments.The interaction between these different habitatss favors, and nutrients.
