Sea WIFS biosphere animation

Watch the global carbon cycle! The link below takes you to a NASA page that loads a 90 megabyte animated GIF file showing chlorophyll concentration (in the oceans) and Normalized Difference Vegetation Index (NDVI, on land) as the seasons change. Note: this page requires a fair bit of computer memory and good internet connection to load the image. It may step around slowly until the image is fully loaded.
