Ocean currents are continuous, directed movements of ocean water driven by forces such as prevailing winds, differences in water density, and global temperature gradients. These movements are vital components of global ocean circulation, which in turn plays a critical role in regulating Earth's climate by redistributing heat energy from the tropics toward the poles. Currents can be categorized as surface currents, which are primarily wind-driven, and deep currents, which circulate through the abyssal zones. The transfer of heat and dissolved nutrients via these currents makes them fundamental to marine ecosystems and the general climate stability of the planet.
