lagúnáció

Lagúnáció is a term used in some contexts to describe the process of forming or being transformed into a lagoon. A lagoon is a shallow body of water separated from a larger body of water by a barrier, such as a reef, sandbar, or barrier island. The formation of a lagoon, or lagúnáció, can occur through various geological and hydrological processes.

One common mechanism for lagúnáció involves the gradual accumulation of sediment along coastlines. Prevailing currents and wave action can deposit sand and other debris, creating natural barriers that enclose a portion of the sea. Over time, these barriers can grow and become more substantial, leading to the formation of a distinct lagoon. Another process can involve the subsidence of land, which may allow a shallow sea to inundate low-lying coastal areas, with offshore reefs or islands acting as the separating barriers.

The characteristics of a lagoon formed through lagúnáció vary greatly depending on factors such as the source of water, the size and permeability of the barrier, and the local climate. Lagoons can be brackish, saltwater, or even freshwater, depending on the balance between freshwater input from rivers or rainfall and the inflow from the adjacent larger water body. These environments are often rich in biodiversity and play important ecological roles, serving as nurseries for fish and supporting unique plant and animal communities. The term lagúnáció, while not universally standardized, encapsulates the dynamic geological and environmental changes that result in the creation of these distinct coastal features.
