Detecting El Niño in Sea Surface Temperature Data
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.

Exploring Seafloor Topography
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.

Looking into Earth with GIS
DATA: Seismic Wave Model Output. TOOLS: My World GIS, Microsoft Excel. SUMMARY: Examine seismic wave data in a Geographic Information System (GIS). Analyze wave velocities to infer the depth of the crust-mantle boundary.
