  • The Ocean ConveyorWoods Hole Oceanographic Institution

    Feb 19 2020 · The Ocean Conveyor was rolling drawing even more Gulf Stream waters northward. Today s climate system is influenced by the ocean s conveyor-like global circulation. Cold salty waters sink to drive the conveyor and warm surface currents complete the loop.

  • What are two things that drive the global conveyor belt A

    The great ocean conveyor moves water around the globe. The global conveyor belt is a system of ocean currents that transport water around the world. The global conveyor enriches carbon dioxide-poor nutrient-depleted surface waters by carrying them through the ocean s belt and it moves much more slowly than surface currents.

    A global conveyor belt This Atlantic current is also called the Atlantic Meridional Overturning Circulation or AMOC. It works like a colossal conveyor belt. It carries warm water along the Atlantic Ocean surface moving from south to north. Near Greenland the current makes a U-turn. Then the cold water sinks and flows south again.
