Analyzing the Antarctic Ozone Hole
DATA: Total Ozone Mapping Spectrometer (TOMS) Images. TOOLS: ImageJ, Spreadsheet. SUMMARY: Animate and explore 10 years of Southern Hemisphere ozone images. Then measure and graph the area of the ozone hole over time.

Annotating Change in Satellite Images
DATA: Landsat Images. TOOL: ImageJ. SUMMARY: Examine time-series images that show landuse changes in China. Produce a map documenting how human activities have changed the coastline.

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.

Pollen and Climate Change
DATA: Pollen Viewer. TOOLS: Analyzing Digital Images, Spreadsheet. SUMMARY: Study the relationship between climate and the distribution of plants across North America, import data into spreadsheet and graph.

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.
