ocean currents
Seas' flowing rivers
Ocean currents are large-scale movements of seawater flowing in consistent patterns across the world's oceans.
Surface currents are driven primarily by wind and the Earth's rotation, while deep currents result from differences in water temperature and salinity.
Major currents like the Gulf Stream and the Humboldt Current profoundly influence regional climates and marine ecosystems.
Ocean currents carry warm water from the tropics toward the poles.
