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. |

| Title |
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. |

Wind 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. Deviations from normal winds speeds and directions of the were computed using data from the Special Sensor Microwave/Imager (SSMI) on the Tropical Rainfall Measuring Mission (TRMM) satellite. |

Sea Surface Temperature 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. 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. |

| Title |
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. |
