Upwelling
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.
