The ocean located to the south of the equator is the Southern Ocean, also known as the Antarctic Ocean. This ocean encircles Antarctica and extends northward to 60 degrees south latitude, playing a crucial role in the Earth's climate and ecosystem. The Southern Ocean is unique due to its cold, nutrient-rich waters and diverse marine life, including species of seals, whales, and seabirds. It is also significant for global ocean currents, which impact weather patterns and climate across the globe. The Southern Ocean supports crucial ecosystems and is a focus for conservation efforts due to climate change and human activities.
