Coastal areas are subjected to erosion from waves breaking on shore and storms. Satellite altimetry from the Jason series can provide information on sea level rise, which can be used in planning beach renourishment to combat erosion.  To further understand coastal processes and monitor coastal erosion a new satellite mission, SWOT, will provide a finer resolution than what the current altimeters can provide.

The El Niño-Southern Oscillation (ENSO) is a quasi-periodic fluctuation of ocean temperatures in the equatorial Pacific. The temperatures generally fluctuate between two states: warmer than normal central and eastern equatorial Pacific (El Niño) and cooler than normal central and eastern equatorial Pacific (La Niña). This animation illustrates the evolution of sea surface temperature (SST) anomalies (relative to the respective normal state) in the Pacific Ocean associated with the developing 2015 El Niño, the warm phase ENSO. SST anomalies reflect the heat content in the mixed layer (upper 50 meters).

The animation illustrates the evolution of sea surface temperature anomaly (SSTA) associated with the 2009-10 El Niño in the Pacific Ocean. The El Niño-Southern Oscillation (ENSO) is a quasi-periodic fluctuation of ocean temperatures in the equatorial Pacific. The temperatures generally fluctuate between two states: warmer than normal central and eastern equatorial Pacific (El Niño) and cooler than normal central and eastern equatorial Pacific (La Niña).

The El Niño-Southern Oscillation (ENSO) is a quasi-periodic fluctuation of ocean temperatures in the equatorial Pacific. The temperatures generally fluctuate between two states: warmer than normal central and eastern equatorial Pacific (El Niño) and cooler than normal central and eastern equatorial Pacific (La Niña). The 1997-98 event was the first major El Niño that was observed extensively by satellites, including those that measured SST and sea surface height (SSH). These measurements are helpful to examine the evolution of an El Niño event.

This visualization from 1 January 2011 to 31 December 2013 shows sea surface temperatures (SST) associated with the Agulhas Current near South Africa at 1-kilometer (~0.6 mile) resolution. The Agulhas Current is a western boundary current that transports warm water southward in the Indian Ocean along the west coast of Africa. Near South Africa the current retroflects (or turns back on itself), called the Agulhas Retroflection, due to interactions with the Antarctic Circumpolar Current. Eddies that form as a result of Agulhas Retroflection are clearly visible in the animation.

This visualization from 1 January 2011 to 31 December 2013 shows sea surface temperatures (SST) in the Eastern Pacific near Central America at 1-kilometer (~0.6 mile) resolution. Cold SSTs are clearly visible off the Central American coast from October to March. Such cooling events are associated with accelerated winds that blow through gaps in the mountainous terrain of Central America.
