What is brackish water?

Brackish water is defined as a mixture of salt and fresh water. It typically occurs in areas where freshwater from rivers or streams meets and mixes with saltwater from the ocean, such as estuaries and mangrove swamps. This unique mixture results in salinity levels that are higher than freshwater but lower than seawater, making brackish water an important habitat for various species of fish, plants, and other aquatic life.

Understanding the characteristics of brackish water is essential for studying ecosystems that rely on this transitional environment, as it influences the types of organisms that can thrive there. This blend of salinities supports a diverse range of species, some of which are specially adapted to live in brackish conditions.
