Randall Jackson, for NASA

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.

Climate Literacy
About Teaching Climate Literacy

Climate change is a significant and persistent change in an area’s average climate conditions or their extremes. Seasonal variations and multi-year cycles (for example, the El Niño Southern Oscillation) that produce warm, cool, wet, or dry periods across different regions are a natural part of climate variability. They do not represent climate change.
About Teaching Principle 4
Other materials addressing 4c
Melting of ice sheets and glaciers, combined with the thermal expansion of seawater as the oceans warm, is causing sea level to rise. Seawater is beginning to move onto low-lying land and to contaminate coastal fresh water sources and beginning to submerge coastal facilities and barrier islands. Sea-level rise increases the risk of damage to homes and buildings from storm surges such as those that accompany hurricanes.

Teaching Tips

  • In-class discussion tool or use as an independent research tool.

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.
  • Comments from expert scientist: This activity presents a good overview over space missions that are concerned with sea level hights, as well as introduces good examples of why this is a relevant topic of research.

About the Pedagogy

  • The video interactive educates the viewer on the roles satellites have played in understanding how sea-level data can be used to understand and predict oceanographic phenomena.
  • It is a unique resource showing the relationship between water temperature and sea-level height.
  • The video has several components that can be examined separately from a computer.
  • There are no prerequisite skills needed.
  • It has well-organized information and lay-out.
  • There is no suggested teaching sequence and no teachers' guide is provided.
  • Students would be engaged.

Technical Details/Ease of Use

  • Easy to use and technically well-produced.
