Measuring Distance and Area in Satellite Images
DATA: MODIS Imagery. TOOL: ImageJ. SUMMARY: Examine images of the Aral Sea from 1973 through 2003. Use image analysis software to measure changes in the width and area of the freshwater lake over time.

Shrinking Forest - Growing Problem
DATA: Synthetic Aperture Radar (SAR) Images. TOOL: ImageJ. SUMMARY: Process and measure time-series SAR images to analyze the rate of deforestation in the Amazon rainforest. Produce a color composite image showing the oldest to most recently deforested areas.

Visualizing Carbon Pathways
DATA: NASA Satellite Images TOOLS: ImageJ and Image Composite Explorer (ICE) of NASA Earth Observations (NEO). SUMMARY: Build animations of satellite data to illustrate and explore carbon pathways through the Earth system.

Whither Arctic Sea Ice?
DATA: Sea Ice Images TOOLS: ImageJ, Spreadsheet application SUMMARY: Animate 30 years of sea ice images and measure the ice extent each year to produce a graph. Compare the ice extents to air temperatures.
