Image showing regions of life in the oceans

This image shows the abundance of life in the sea, measured by the SeaWiFS instrument aboard the Seastar satellite. 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. NASA has posted a large gallery of great images for Earth Day.

    It would be interesting to see the change in dark blue region in retrospect. How has life in the sea over time? Maybe this information will be useful for scientists and society for people who care about the environmental component of our planet ..
