| Title |
Life Returns to the Galapagos after El Nino (WMS) |
| Abstract |
During the El Nino in 1997 and 1998, the surface water in the eastern equatorial Pacific off the coast of South America was warmer than normal. This warm water trapped the ocean nutrients that normally come to the surface in the upwelling cold water, leading to a drastic decrease in phytonplankton and other ocean life in the region. The unique Galapagos ecosystem was severely affected and many species, including sea lions, seabirds, and baracudas, suffered a very high mortality level. During the second week of May, 1998, the ocean temperatures plummeted 10 degrees in one day, and the ocean productivity exploded with large phytoplankton blooms. After this time, many species recovered very rapidly and the land species started to reproduce immediately. The SeaWiFS instrument, which monitors global phytoplankton in the oceans by measuring the color of reflected light, caught this dramatic recovery. This visualization shws images from SeaWiFS starting on May 10, 1998 and ending on May 31, 1998, where ocean colors of blue or purple represents little or no ocean life and colors or yellow and red indicate significant ocean productivity. White and gray denote areas occluded by clouds in these images, and a relief image of the Galapagos Islands has been superimposed on the images to clarify the location of the islands. |

| Title |
SeaWiFS: El Nino on a Globe (2nd version) |
| Abstract |
By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. Until now, scientists have only had a continuous record of photosynthesis on land. But following three years of continual data collected by the SeaWiFS instrument, NASA has gathered the first record of photosynthetic productivity in the oceans. By taking three years of continuous data as a whole, experts have been able to map trends and anomalies in the global circulation of carbon to a degree of detail than has never been done before. It is a baseline measurement to by which all future measurements will be compared. |

Sea Surface Height Anomalies during El Nino/La Nina Event of 1997-1998 (WMS) |
| Abstract |
The El Nino/La Nina event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. Changes in the normal height of the ocean's surface were observed by the TOPEX/Poseidon altimeter. |

| Abstract |
The El Nino/La Nina event in 1997-1999 was particularly intense, but was also very well observed by satellites and buoys. A strong upwelling of unusually warm water was observed in the Pacific Ocean during the El Nino phase, followed by unusually cold water in the La Nina phase. The Advanced Very High Resolution Radiometer (AVHRR) instrument on the US National Oceanic and Atmospheric Administration's NOAA-14 spacecraft observed the changes in sea surface temperature shown here. |

Indecisive El Nino Exhibits 'Split Personality' |
| Abstract |
The central equatorial Pacific Ocean warmed by about one degree Celsius (1.8 degrees Fahrenheit) between June and August 2004, which can indicate development of a weak to moderate El Nino. Yet in other locations, important signals have been absent, suggesting the climate pattern may be of two minds. NASA satellites show warm water anomalies concentrated in the central Pacific Ocean in August. By September, the anomalies are weaker. The SeaWinds instrument on NASA's Quick Scatterometer (QuikScat) satellite has shown stronger than normal trade winds for this time of year on the eastern side of the Pacific basin. Since the 1997 to 1998 El Nino, these trade winds have exhibited a kind of 'split personality' condition during times when the central equatorial Pacific warmed. |
