NeMO studies the dynamic interactions between submarine volcanic activity and seafloor hotsprings at an observatory called Axial Seamount. The research activities at NeMO provide an extraordinary educational opportunity, both from the daily reports from expeditions at sea and from creative learning materials based on NeMO results. The site features curriculum materials designed for high school and ... Full description.

The Global Climate Animations site contains animations of the Earth's climate system for educational and research purposes. The animations show the climatology of the seasonal cycle for selected climate variables for the time period 1959-1997, based on data from the NCEP/NCAR 40-Year Reanalysis Project. The individual frames in each animation show the map pattern of the long-term monthly averages ... Full description.

Virtual Earthquake is an interactive web-based program designed to introduce the concepts of how an earthquake epicenter is located and how the Richter magnitude of an earthquake is determined. Virtual Earthquake shows the recordings of an earthquake's seismic waves detected by instruments far away from the earthquake. The instrument recording the seismic waves is called a seismograph and the recording ... Full description.
