Sea surface temperature monitor and predict the El Niño phenomenon. Weather satellites have been available to determine sea surface temperature information since 1967, with the first global composites created during 1970. Since 1982, satellites have been increasingly utilized to measure SST and have allowed its spatial and temporal variation to be viewed more fully. Satellite measurements of SST are in reasonable agreement with in situ temperature measurements. The satellite measurement is made by sensing the ocean radiation in two or more wavelengths within the infrared part of the electromagnetic spectrum or other parts of the spectrum which can then be empirically related to
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
