The "Ocean Conveyor Belt" is the entire ocean circulation system which is driven by surface heat, fresh water infiltration and changes in salt content throughout the oceans. These changes throughout the oceans create sinking and mixing throughout the ocean basins and a pathway of these waters mix heat, solids, and gases across the entire globe to create uniformity throughout the oceans. <span style="font-size: 10pt; color: rgb(19,17,17); font-family: Arial;">
