An abundance of plankton can be found in what ocean?

An abundance of plankton can be found in various oceans, but the Southern Ocean is particularly notable for its rich planktonic communities. This ocean, surrounding Antarctica, supports a diverse array of phytoplankton and zooplankton, which thrive in its nutrient-rich waters. Additionally, upwelling zones in other oceans, such as the Pacific and Atlantic, also experience high concentrations of plankton due to nutrient availability.
