Sea-viewing Wide Field-of-view Sensor (SeaWiFS) on board the Orbview 2 satellite captured the phytoplankton bloom October 6, 2002 . Red represents high concentration of chlorophyll, follow by orange, yellow and green. Land and cloud portions of the image are presented in natural color. SeaWiFS monitors ocean plant life by measuring the amount of chlorophyll in the ocean. Large phytoplankton blooms ... Full description.

Comment on this resource
The Microwave Limb Sounder (MLS) measures microwave emission from ozone and chlorine monoxide, a major ozone destroying radical. Right after UARS was launched, MLS began to measure large concentrations of chlorine monoxide over the south pole. These dramatic images clearly showed the extent of the south polar ozone destruction and confirmed the connection between man-made chlorine and the formation ... Full description.

Comment on this resource
This video summarizes science and data obtained by the Upper Atmosphere Research Satellite (UARS) mission. UARS was launched in 1991 to study ozone depletion and the processes that control the stratospheric ozone layer. Although the mission was intended to last only 18 months, UARS continued to operate 7.5 years after launch with 8 of the 10 instruments at the time this video was made. UARS has been ...

DISAPPEARING WATER: THE ARAL SEA OVER TIME, FROM 1973 TO 2001 A time series is a powerful illustrative tool. Where in the case of Las Vegas we see the direct effects of people on the land, in the case of the Aral Sea, separating the countries of Kazakhstan and Uzbekistan, we see indirect, but no less dramatic effects on a different part of the world. The Aral Sea is actually not a sea at all. It is ... Full description.

Comment on this resource
The Aral Sea is actually not a sea at all, but an immense fresh water lake. In the last thirty years, more than sixty percent of the lake has disappeared because much of the river flow feeding the lake was diverted to irrigate cotton fields and rice paddies. Concentrations of salts and minerals began to rise in the shrinking body of water, leading to staggering alterations in the lakes ecology and ... Full description.
