    In the ocean, minerals, detritus, bits of shells, and dead organisms
    constantly drift down to the ocean floor. An upwelling of cold water
    carries them back up to the surface where they provide plankton and
    zooplankton, with nourishment. The phytoplankton and zooplankton, in
    turn, nourishment other kind of life. This is why areas of upwelling
    often have abundant sea life.
