2009-2010 El Niño-Southern Oscillation (ENSO) Sea Surface Temperature Anomalies (SSTA)

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).

 

 

1997-1998 El Niño-Southern Oscillation (ENSO) Sea Surface Temperature Anomalies (SSTA)

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.

A View from Above: Wastewater Diversion Plumes in Southern California (October, 2014)

The Hyperion Treatment Plant (HTP) and the Orange County Sanitation District (OCSD) are wastewater treatment facilities that discharge into the Southern California Bight. HTP and OCSD wastewater is diverted on occasion to shorter outfall pipes at shallower depths that increase risks to human health and water quality. Here the utility satellite data to detect such diversions is examined.
