Sea surface temperature temperature pattern is when warm water spreads from the west Pacific and the Indian Ocean to the east Pacific. It takes the rain with it, causing extensive drought in the western Pacific and rainfall in the normally dry eastern Pacific. El Niño's warm rush of nutrient-poor tropical water, heated by its eastward passage in the Equatorial Current, replaces the cold, nutrient-rich surface water of the Humboldt Current. When El Niño conditions last for many months, extensive ocean warming and the reduction in Easterly Trade winds limits upwelling of cold nutrient-rich deep water and its economic impact to local fishing for
The Ocean Cleanup next step is to test their new drifting system in the North Pacific in 2017. In May 2017, significant changes to the design were made: The Ocean Cleanup performed more scale model tests in 2018. The sea anchors were removed because the wind moved the system faster than the plastic. The opening of the U would face the direction of travel, which would be achieved by having the underwater screen deeper in the middle of the system, creating more drag. On September 9, 2018, "System 001" (nicknamed "Wilson" in reference to the floating soccer ball in the 2000 film "Cast
