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
Corvallis to the Sea Trail had more than 40,000 volunteer hours and $20,000 in donations. The effort began in 1974 but failed due to private property permission difficulties. In 2004, the C2C partnership was created and it proved able to work with Siuslaw National Forest officials. Corvallis to the Sea Trail Corvallis to the Sea Trail is a long hiking, bicycling, and equestrian trail in Western Oregon (United States) which links the Willamette Valley to the Pacific Ocean. It connects between Corvallis and Ona Beach. As of September 9, 2017, it is approximately 50% complete with the eastern half open and crosses a patchwork of
