The South Atlantic Gyre is a large system of rotating ocean currents located in the southern part of the Atlantic Ocean. It is part of the global ocean circulation and plays a crucial role in regulating climate and marine ecosystems. The gyre is driven by the trade winds and the Earth's rotation, creating a circular flow of water that influences weather patterns and ocean temperatures. This gyre is also associated with the South Atlantic Subtropical Convergence Zone, where warm and cold waters meet, leading to rich marine biodiversity. The currents within the gyre help distribute nutrients and support various marine life, making it an important area for fishing and ecological studies.
