Analyzing the Antarctic Ozone Hole
LuAnn Dahlman
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.

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.

Using Satellite Images to Understand Earth's Atmosphere
DATA: NASA Satellite Images. TOOLS: ImageJ and Image Composite Explorer (ICE) of NASA Earth Observations (NEO). SUMMARY: Use ImageJ to create an animation showing the change in monthly concentration of aerosols over the course of a year and compare it to a similar animation showing change in carbon monoxide concentration. Then use NEO ICE to create histograms and scatter plots, investigating the relationship between aerosol concentration and carbon monoxide concentration.

Detecting El NiÃo in Sea Surface Temperature Data
David Smith, GLOBE; Betsy Youngman
DATA: Sea Surface Temperature (SST). TOOL: My World GIS. SUMMARY: Examine 15 years of SST data from the Pacific Marine Environmental Laboratory. Create and analyze average SST maps to identify El Nino and La Nina events.

Using NASA NEO and ImageJ to Explore the Role of Snow Cover in Shaping Climate
DATA: NASA Satellite Images. TOOLS: ImageJ and Image Composite Explorer (ICE) of NASA Earth Observations (NEO). SUMMARY: Explore and animate satellite images of reflected short wave radiation, snow cover, and land surface temperature downloaded. Then observe, graph, and analyze the relationship between these three variables.

Annotating Change in Satellite Images
LuAnn Dahlman
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.

Exploring Seafloor Topography
Sandra Swenson
DATA: Digital Elevation Model Data. TOOL: GeoMapApp. SUMMARY: Explore a timeline about how we have learned about the oceans. Construct a profile across the Atlantic Ocean and create 3-D visualizations of the seafloor.

Annotating Satellite Images
Rebecca Teed, Wright State University-Main Campus
During this exercise, students compare a series of satellite images taken 3-4 years apart to investigate the effects of human land use and annotate the images using ImageJ software. -

Investigating Earthquakes with ArcVoyager GIS
Carla McAuliffe; David Smith, GLOBE; Joseph Kerski
DATA: Recent and Historical Earthquake Data TOOL: ArcVoyager Special Edition GIS - Explore earthquake data and import them into a Geographic Information System (GIS). Analyze the data to predict where the next big earthquake will occur.

Measuring Distance and Area in Satellite Images
LuAnn Dahlman
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.

When is Dinner Served? Predicting the Spring Phytoplankton Bloom in the Gulf of Maine
Denise Blaha; Amy Holt Cline, University of New Hampshire-Main Campus
DATA: Ocean Buoy Data, MODIS Images TOOLS: GoMOOS Online Graphing Tool - Learn about conditions that influence the spring phytoplankton bloom. Use an online graphing tool to predict the date of the bloom.

Exploring and Animating GOES Images
Nick Haddad
DATA: GOES Weather Images. TOOL: ImageJ. SUMMARY: Transform a time series of GOES images into an animation. Plot a storm track and determine storm speed.

Water Availability
DATA: North American Regional Reanalysis (NARR). TOOL: FieldScope GIS. SUMMARY: Use an online GIS from the National Geographic Society, to investigate the relationship between precipitation, evaporation, and surface runoff.
