Exploring Ocean Life and Color on the Internet - Red Nova
A new NASA Internet tool called "Giovanni" allows high school and college students and researchers to access and analyze satellite-derived ocean color data. Ocean color data provides students with information about ocean biology by looking at phytoplankton through changes in the color of the ocean surface. "Ocean color" refers primarily to the measurement of the green pigment called chlorophyll, which is contained in phytoplankton. Phytoplankton are free-floating plants that are the foundation of the ocean's food chain. http://reason.gsfc.nasa.gov/Giovanni/
