Aftereffects of 2003 heat wave on the Mediterranean sea surface temperature, as seen by models assimilating altimetry

The catastrophic shrinking of the Aral Sea level is continuing. However, this drying-up of the Aral Sea is not the first in History.

Altimeter measurements provide data for operational nowcasting and forecasting of the basin-scale circulation of the Black Sea.

Altimetry cannot give the wave heights every hour, but it is a good technique for identifying trends and gives some idea of the minimum and maximum heights.

Since salinity along with temperature, determines the water density, it thus has an impact on ocean circulation, and thus can be estimated using altimetry

Sea floor relief (or bathymetry) affects the sea surface topography

Measurements at sea complete, extend and are used as reference with respect to space techniques

T/P - Jason-1 tandem shows the possibilities of a constellation of optimized altimetric satellites.

The Loop Current enters the Gulf of Mexico between the Yucatan Peninsula and Cuba, and makes a loop. Sometimes, this loop breaks, and forms a lone eddy.

Twelve African lakes can be monitored since 1992 from Topex/Poséidon

Large scale ocean currents flow along the lines of equal dynamic topography

Ocean color measurements are interesting for understanding phytoplankton life cycle, with respect to the physical parameters of the ocean when combined with altimetry.
