Arctic and Antarctic studies of the two polar regions of earth (NSF)

Microbial Life - focuses on the ecology, diversity, and evolution of micro-organisms. Learn about marine microbes and extremophile microbes that live in inhospitable environments. Explore the Gulf of Mexico Dead Zone and the red tide through case studies. Find out about microbial observatories and extreme environments, including Mono Lake (in California's Eastern Sierra), Octopus Spring (in Yellowstone National Park), and others. (NSF)

Global Change Master Directory - earth science data and services

Ice Stories: Dispatches from Polar Scientists - features photos, blogs, and webcasts of penguin biologists, glaciologists, cosmologists, geologists, and marine scientists working in Antarctica and the Arctic documenting their research and sharing discoveries. (National Science Foundation)

Energy and Material Cycles Visualizations - animations, images, graphs, and photos on the carbon cycle, greenhouse gases, sea ice, sea level change, interglacial cycle, continental drift, tectonic cycle, and the hydrologic cycle. (Carleton College & NSF)

Teaching

Teaching Geoscience with Visualizations - dozens of animations for teaching geoscience topics -- atmosphere, biosphere, climate, earth's surface, energy and material cycles, geology, human dimensions, hydrosphere and cryosphere, hydrology, ocean, solar system, solid earth, earth history, and more; learn what makes an effective visualization and best practices for using visualizations in the classroom.
