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
In the Heart of the Sea "". In the Heart of the Sea In the Heart of the Sea: The Tragedy of the Whaleship Essex is a book by American writer Nathaniel Philbrick about the loss of the whaler "Essex" in the Pacific Ocean in 1820.
