What Really Keeps Ocean Currents Moving Around Earth

This video explains the three main drivers of ocean currents—wind, tides, and density differences—for viewers curious about how the seas connect to weather, climate, and marine life. It traces surface flows like the Gulf Stream and deep thermohaline circulation including the AMOC, showing how these currents redistribute heat and nutrients globally. The explainer highlights why the ocean's circulatory system matters far beyond the shoreline and how climate change may be altering its stability.
