Analyzing monthly environmental data from the North Atlantic Ocean will help you to learn more about how the water cycle affects sea surface salinity. Your challenge is to find the data set that most closely corresponds to sea surface salinity patterns.
The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.
Students will investigate the differences in sea surface height during an El Niño event by creating a model with gelatin, sherbet and whipped creme.
Students will use coloring sheets to create a color coded model of El Niño. If the Data Literacy Map Cube is used with this, students should color their models first.
This investigation is part of the NASA: Mission Geography Module "What are the causes and consequences of climate change?" that guides students through explorations in climatic variability and evidence for global climate change.
Students will examine a 2014-2015 El Nino Southern Oscillation (ENSO) event to identify relationships among sea surface height, sea surface temperature, precipitation, and wind vectors.
Can you tell El Nino from La Nina? This interactive was created by UCAR Center for Science Education using satellite images of the height of the ocean surface. Students interpret these images to identify whether they represent El Nino, La Nina, or neither event (La Nada!).
This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

This activity invites students to model and observe the effect of melting ice sheets (from land) on sea level and the difference between the effect of melting sea-ice to that of melting land ice on sea level.
