The global ocean chlorophyll archive produced by the CZCS was revised using compatible algorithms with SeaWiFS. Both archives were then blended with in situ data to reduce residual errors. This methodology permitted a quantitative comparison of decadal changes in global ocean chlorophyll from the CZCS (1979 - 1986) and SeaWiFS (1997 - 2000) records. Global spatial distributions and seasonal variablility ... Full description.

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.

DISAPPEARING WATER: THE ARAL SEA OVER TIME, FROM 1973 TO 2001 A time series is a powerful illustrative tool.

The Aral Sea is actually not a sea at all. It is ... Full description.
