Thermohaline circulation refers to the large-scale movement of ocean water caused by differences in its temperature and salinity. Synonyms for thermohaline circulation include the ocean's conveyor belt, the global ocean conveyor, and the Meridional Overturning Circulation. A critical component of the Earth's climate system, thermohaline circulation plays a significant role in regulating global temperatures and influencing weather patterns. Understanding the mechanisms behind this circulation is crucial for predicting changes in ocean currents, sea level rise, and climate patterns. With ongoing research and advancements in technology, scientists are continually studying the ocean's conveyor belt to gain new insights into this vital component of Earth's climate system.
