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
Magellan Rise (ocean plateau) Magellan Rise (ocean plateau) Magellan Rise is an oceanic plateau in the Pacific Ocean, which covers a surface area of . There is another "Magellan Rise" west from the Marshall Islands as well. The Magellan Rise has been called a large igneous province by Coffin and Endholm 2001 and was emplaced 145 million or 135-128 million years ago, possibly as a consequence of intense volcanism at a former triple junction. Alternatively, the Rise was formed by a mantle plume. Candidate mantle plumes are the Easter hotspot and the Foundation hotspot. The volume of rocks in the Magellan Rise is about
