The Antarctic Circumpolar Current (ACC) is a powerful ocean current that flows around the continent of Antarctica. It is the world's largest ocean current, moving from west to east and connecting the Atlantic, Pacific, and Indian Oceans. The ACC plays a crucial role in regulating global climate and ocean circulation. This current is driven by strong westerly winds and is characterized by its cold, nutrient-rich waters. It helps to distribute heat and nutrients across the oceans, supporting marine ecosystems and influencing weather patterns. The ACC is vital for maintaining the balance of oceanic and atmospheric systems worldwide.
