Whirling currents, also known as EDDIES, are swirling masses of water or air that move in a circular motion. They are created when a larger body of water or air is disturbed by an outside force, such as a rock or a gust of wind. EDDIES can be small or large, and can last for a few minutes or several days. They can form in oceans, rivers, and even in the atmosphere. Whirling currents can have a significant impact on the environment, influencing the movement of sediment, nutrients, and pollutants.
