Background information on sea level change.

Explore the energy and matter cycles found within the Earth System. 

GLOBE protocols and learning activities that complement the Sea Level Change phenomenon are outlined.

Explore and connect to pedosphere protocols in GLOBE. Each protocol correlates to related datasets from the Earth System Data Explorer.

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.

The My NASA Data visualization tool, Earth System Data Explorer (ESDE), helps learners visualize complex Earth System data sets over space and time. Visit this page to review the datasets we have available to you and their organization by Earth System sphere, science variable, dataset name, and start/end dates. 

Phytoplankton distribution background information.

The world's surface air temperature is getting warmer. Whether the cause is human activity or natural changes in the Earth System—and the enormous body of evidence says it’s humans—thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution.
