These are video and animations of sea level from NASA's Climate website. Since 1992, NASA and CNES have studied sea surface topography as a proxy for ocean temperatures. NASA Missions TOPEX/Poseidon, Jason 1 and Jason 2 have been useful in predicting major climate, weather, and geologic events including El Nino, La Nina, Hurricane Katrina, and the Indian Ocean Tsunami.
About the Science
- This video interactive educates the viewer on the role that satellites play in studying the topography and temperature of sea water. It also shows how satellites can provide useful information for understanding and predicting major oceanographic events.
- Digital satellite imagery is used throughout to show changes in sea surface height and temperature.
- Background information is available by clicking on the "find out more" button.
- Passed initial science review - expert science review pending.
