Oceanography in the formal and informal classroom

The TOPEX/Poseidon and Jason-1 ocean altimeter missions offer the educator in the middle school or informal education venue a unique opportunity for reinforcing ocean science studies. An educational poster from NASA's Jet Propulsion Laboratory and France's Centre National d'Etudes Spatiales provide teachers and students a tool to examine topics such as the dynamics of ocean circulation, ocean research, and the oceans' role in climate.

TOPEX/Poseidon Radiation Issues: Displacement Damage in Optocouplers

In this paper we describe observed failures of optocouplers on the TOPEX/Poseidon (T/P) ocean measuring satellite. An indirect assessment is made of proton doses by the spacecraft, and these data are compared with laboratory proton irradiations of optocouplers. It is shown that the T/P failures occur at expected doses for proton-induced displacement damage.

7th AAS/AIAA Space Flight Mechanics Meeting

TOPEX/Poseidon is a joint American/French ocean topography experiment conducted by the National Aeronautics and Space Administration (NASA) and the Centre National d'Etudes Spatiales (CNES)...Specifically, the paper first presents the present task configuration. Changes implemented after the prime mission are then discussed. Four areas of statistical performance are emhaszed and presented in detail...finally, the paper addresses problems encountered and lessons learned.

The Ocean and Climate: Results from the TOPEX/POSEIDON Mission

Since 1992, the TOPEX/POSEIDON satellite has been making altimetric sea surface observations with a sea level accuracy of 4.4 cm. This data can be used for studying regional and seasonal differences in sea level and for evaluating oceanic circulation models and tidal models. Longer term changes can also be studied, such as El Nino and overall sea level rising (although the latter is still within the margin of error).

Comparison of TOPEX/Poseidon Sea Level Observations to Simulations by the Los Alamos Ocean General Circulation Mode

The sea level observations from the TOPEX/Poseidon radar altimeter from October, 1992 to October, 1994 were used to study the circulation of the global oceans and their temporal changes. To provide a framework for interpreting the observations, the Parallel Ocean Program model of the Los Alamos National Laboratory was run for the same period of time for comparison. A report of that data is given.
