By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. This animation represents the first six years' worth of data taken by the SeaWiFS instrument, showing the abundance of life both on land and in the sea. In the ocean, dark blue represents warmer areas where there is little life due to lack of nutrients, and greens and reds represent cooler nutrient-rich areas. The nutrient-rich areas include coastal regions where cold water rises from the sea floor bringing nutrients along and areas at the mouths of rivers where the rivers have brought nutrients into the ocean from the land. On land, green represents areas of abundant plant life, such as forests and grasslands, while tan and white represent areas where plant life is sparse or non-existent, such as the deserts in Africa and the Middle East and snow-cover and ice at the poles.

This animation shows the first six years worth of biosphere data taken by the SeaWiFS instrument. On land, areas of high plant life are shown in dark green, while areas of low plant life are shown in tan. In the ocean, areas of high phytoplankton are shown in red, and areas of lowest phytoplankton are shown in blue and purple.

This product is available through our Web Map Service.

This is the legend for the global biosphere animation. There are two different, but related, types of data shown. On land, plant life is denoted in shades of tan (low) and green (high), while reds and yellows denote areas of high ocean chlorophyll and blues denote low concentrations.

The large animation above is split into smaller pieces that can be played on the hyperwall. Each piece is named according to a standard spreadsheet convention with a1 at the upper left and c3 at the lower right. This image illustrates this naming convention used in the diced-up frame sets below.
