The cause of this is from wind driven currents and a resulting process called Ekman transport.
WebThis process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is … WebUpwelling occurs when strong polar winds blow across the surface of the water.

WebJul 15, 2024 · Scientists discovered that in certain regions of the ocean, the nutrient -rich deep water was upwelling, or rising to the surface. Scientists realized that the ocean was slowly turning over from top to bottom in a continuous global loop. Like a conveyor belt, thermohaline circulation moves nutrients from one part of the ocean to another.
WebUpwelling is an oceanic process in which cold water from the deep rises toward the surface of the ocean. It is caused by strong winds and the rotation of the Earth which moves warmer surface waters offshore allowing the cold, nutrient rich water to rush up.
