This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.
How much do you know about the frozen poles of our home planet?
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.
This mini-lesson features time-series graphs of mean salinity at the surface for the Arctic and Antarctic regions. A series of questions guides students in their analysis.
Test your knowledge of sea level rise and its effect on global populations.
Students explore positive feedback effects of changing albedo from melting Arctic sea ice.
Test your knowledge of soil moisture and its effect on global populations. Soil moisture is the amount of water contained
Background information on ocean circulation.
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.
