Description:
A joint US and France project, the TOPEX-Poseidon satellites continuously measure sea surface height. The oceans store and transport solar heat, helping to keep Earth's climate in balance. The overall shape of the oceans' "hills" and "valleys" is called ocean surface topography, or OST. Precise knowledge of OST is essential to predict the effects of catastrophic storms. Educational resources available for all ages and backgrounds. Outstanding animation of OTS also included.
